代理Agency
代理关系的成立要件Formation of Agency
代理是一种法律关系，当委托人（Principal）与代理人（Agent）双方同意，由代理人为了委托人的利益（Benefit）并在委托人的控制（Control）下行动，且代理人也同意这样行动时，代理关系即告成立。成立代理关系不需要书面合同，也不需要支付对价。
An agency relationship is created when a principal and an agent manifest assent that the agent shall act on the principal's benefit and subject to the principal's control, and the agent consents so to act. No written contract or consideration is required to form an agency.
甲让乙帮其去超市购买办公用品，并嘱咐乙必须在100美元预算内购买。乙表示同意。此时，由于存在双方的合意、为了甲的利益以及甲对购买范围的控制，甲与乙之间成立了代理关系。
A asks B to buy office supplies for him at the supermarket, instructing B to stay under a 100-dollar budget. B agrees. Here, an agency relationship is formed because there is mutual assent, action for the benefit of A, and control by A over the scope.
雇员与独立合同工的区分Employee versus Independent Contractor
区分代理人是雇员（Employee）还是独立合同工（Independent Contractor）至关重要，因为这直接决定了委托人是否需要承担侵权替代责任。核心衡量标准是委托人是否控制或有权控制代理人工作时的具体工作方式和方法（Manner and Means）。
Distinguishing between an employee and an independent contractor is critical because it determines whether the principal is vicariously liable in tort. The primary test is whether the principal controls or has the right to control the manner and means of the agent's performance.
实际授权：明示与默示Actual Authority: Express and Implied
实际授权（Actual Authority）取决于委托人向代理人传递的信息。基于委托人的言行，如果一个理性的代理人认为自己拥有采取某种行动的权力，则实际授权存在。实际授权分为明示（Express）与默示（Implied）两种。
Actual authority depends on communication between the principal and the agent. It exists if a reasonable agent, based on the principal's words or conduct, would believe they have the authority to act. It can be either express or implied.
明示实际授权是委托人通过口头或书面语言直接赋予代理人的权力。默示实际授权则是指代理人基于履行明示授权所必须的、习惯上的或委托人以往的默认行为，而合情合理地认为自己拥有的附带权力（Incidental Power）。
Express actual authority is directly granted by the principal through oral or written words. Implied actual authority includes incidental powers that the agent reasonably believes they possess based on custom, past practices of acquiescence, or actions necessary to accomplish the express authority.
甲雇佣乙管理其名下的 ABC 生意，明示授权乙‘运营该店’。虽然甲没有明示提及，但乙为了维持经营而雇佣清洁工并支付水电费的行为，属于享有默示实际授权。
A hires B to manage his business, ABC Business, expressly authorizing B to 'run the store.' Although A never explicitly mentions it, B has implied actual authority to hire cleaners and pay utility bills to maintain operations.
表见授权Apparent Authority
表见授权（Apparent Authority）取决于委托人向第三人（Third Party）传递的信息。如果委托人的言行导致一个理性的第三人合理地相信，该代理人拥有代表委托人订立合同的权力，则表见授权成立。仅凭代理人自己宣称拥有权力的言行，不能创设表见授权。若委托人完全隐名，第三人根本不知道委托人存在，因此通常不能成立表见授权；相反，若委托人公开赋予代理人某一职位或角色，该职位通常具有的交易权限可能支持表见授权，即使委托人私下限制了代理人。
Apparent authority depends on manifestations traceable to the principal and received by the third party. It exists when the principal's words, conduct, position, or other manifestations cause a reasonable third party to believe that the agent has authority to bind the principal. The agent's own self-serving representations cannot create apparent authority. If the principal is completely undisclosed, apparent authority usually cannot arise because the third party does not even know the principal exists; by contrast, a publicly assigned title or role may support apparent authority for the usual authority associated with that position despite private limits.
甲带乙去拜访供应商丙，并对丙说：‘乙是我的首席采购员。’随后甲私下告诉乙禁止购买任何红酒。如果乙违背私下指令代表甲向丙订购了红酒，由于甲向丙作出了表示，乙虽无实际授权，但对丙构成表见授权，甲仍需承担合同责任。
A takes B to meet supplier C and tells C, 'B is my chief purchasing agent.' Later, A privately instructs B not to buy any wine. If B disobeys and orders wine from C on A's behalf, B has apparent authority as to C due to A's statement, making A liable on the contract despite the lack of actual authority.
追认Ratification
如果代理人在订立合同时完全缺乏授权（既无实际授权也无表见授权），委托人事后仍可以通过追认（Ratification）选择受该合同约束。追认赋予该合同与事前获得授权同等的法律效力。
If an agent enters into a contract completely unauthorized (lacking both actual and apparent authority), the principal may still choose to be bound by the contract through ratification. Ratification gives the transaction the same legal effect as if it had been authorized from the beginning.
有效的追认必须满足以下要件：委托人必须对合同的所有实质性事实有充分的了解（Knowledge）；委托人必须追认合同的全部内容，不能选择性地只追认有利条款；且追认不能改变第三人在追认前已经取得的合法权利。
For ratification to be effective, the principal must have knowledge of all material facts of the contract; the principal must ratify the entire transaction and cannot selectively adopt only beneficial terms; and ratification cannot alter the intervening rights of third parties.
委托人身份分类与合同责任Disclosed, Partially Disclosed, and Undisclosed Principals
根据第三人在订立合同时对委托人身份的认知，委托人分为三类：显名委托人（Disclosed Principal，第三人知道代理人代表委托人且知道委托人是谁）、部分显名委托人（Partially Disclosed Principal，第三人知道存在委托人，但不知道其具体身份）、以及隐名委托人（Undisclosed Principal，第三人误以为代理人是为自己利益独立行动，完全不知道委托人的存在）。
Based on the third party's knowledge at the time of contracting, principals are classified into three types: disclosed (third party knows the agent acts for a principal and knows the principal's identity); partially disclosed (third party knows a principal exists but not their identity); and undisclosed (third party believes the agent is acting solely on their own behalf and is unaware of any principal).
只要代理人拥有合法授权（实际或表见），委托人通常对第三人承担合同责任。代理人的自身责任取决于委托人的分类：若属于显名委托人，代理人通常不对合同承担个人责任；若属于部分显名或隐名委托人，代理人与委托人都可能对第三人承担合同责任。但在传统普通法下，第三人不能就同一合同获得双重全额赔偿，许多题目会要求第三人在最终判决前选择追究代理人或委托人。
If the agent has proper authority (actual or apparent), the principal is generally liable on the contract. The agent's own liability depends on the disclosure type: if the principal is disclosed, the agent is usually not personally liable; if the principal is partially disclosed or undisclosed, both the agent and the principal may be liable to the third party. Under traditional common law, however, the third party cannot obtain a double full recovery on the same contract, and many exam questions frame this as an election before final judgment between the agent and the principal.
侵权责任：雇主替代责任与直接责任Tort Liability: Vicarious Liability and Direct Liability
根据雇主替代责任原则（Respondeat Superior），若代理人属于雇员，且其侵权行为发生于雇佣范围（Scope of Employment）之内，则委托人需要承担连带侵权责任。对于独立合同工的侵权行为，委托人通常不承担替代责任，除非该工作属于不可转让的义务（Non-delegable Duty）或具有高度危险性（Inherently Dangerous Activity）。
Under respondeat superior, a principal may face vicarious liability for torts committed by an employee acting within the scope of employment. A principal is generally not vicariously liable for torts committed by an independent contractor, unless the work involves a non-delegable duty or an inherently dangerous activity.
划分雇佣范围时，必须区分绕道（Detour）与擅离职守（Frolic）。绕道是指雇员在执行任务时发生轻微、短暂的偏离，这仍在雇佣范围内，委托人需承担责任；擅离职守则是指雇员彻底偏离了雇主的业务而追求个人目的，超出了雇佣范围，委托人免除替代责任。
In determining the scope of employment, a distinction is made between a detour and a frolic. A detour is a minor, foreseeable deviation from the employer's business, which remains within the scope of employment. A frolic is a major abandonment of the employer's business for personal purposes, which falls outside the scope of employment.
乙是 ABC 公司的送货司机。在送货途中，乙开着货车偏离正常路线一个街区去买杯咖啡，期间撞伤了路人丙。这属于‘绕道’， ABC 公司需承担替代责任。若乙擅自开车前往五十英里外的游乐园游玩，在途中撞伤丙，则属于‘擅离职守’， ABC 公司不承担替代责任。
B is a delivery driver for ABC Corporation. While delivering, B drives one block off the regular route to buy coffee and hits pedestrian C. This is a detour, so ABC Corporation faces vicarious liability. If B drives fifty miles away to an amusement park for personal pleasure and hits C, this is a frolic, so ABC Corporation is not vicariously liable.
除替代责任外，如果委托人自身存在过错，也会承担直接责任（Direct Liability）。例如，委托人明知代理人没有驾驶执照或有暴力倾向，却仍将其雇佣或派往客户家中工作（过失雇佣或过失留任，Negligent Hiring or Retention）。
Independent of vicarious liability, a principal faces direct liability if the principal was personally negligent. This occurs, for example, if the principal hires or retains an agent knowing they are unlicensed or have dangerous propensities (negligent hiring or retention).
代理人的信义义务Agent's Fiduciary Duties
代理人对委托人负有信义义务（Fiduciary Duties）。如果代理人违反了这些义务，委托人可以撤销相关交易、追讨代理人获得的所有不当利益或秘密利润，并要求赔偿损失。这些信义义务主要包括：
An agent owes fiduciary duties to the principal. If an agent breaches these duties, the principal can rescind the transaction, disgorge secrets profits, and seek damages. These duties primarily include:
代理关系的终止与残留表见授权Termination of Authority and Lingering Apparent Authority
代理关系可通过双方行为终止（如任何一方单方撤回同意或通知对方），或依法自动终止（如委托人或代理人死亡、丧失行为能力）。一旦终止，代理人的实际授权（明示和默示）立即消灭。
An agency relationship terminates by acts of the parties (such as unilateral revocation or notification) or by operation of law (such as death or incapacity of either the principal or the agent). Upon termination, the agent's actual authority immediately ceases.
然而，实际授权的消灭并不必然消除表见授权。如果第三人先前知道该代理权的存在，但在代理权终止后仍未收到合理的终止通知，则该代理人对该第三人可能依然拥有残留表见授权（Lingering Apparent Authority）。为了消除残留表见授权，委托人必须向曾有过往交易的第三人发出实际通知（Actual Notice），并向其他潜在第三人发出公告通知（Constructive Notice）。
However, the termination of actual authority does not automatically extinguish apparent authority. If a third party previously knew of the agency and has not received proper notice of its termination, the agent may still possess lingering apparent authority. To eliminate this, the principal must give actual notice to third parties who have previously dealt with the agent, and constructive notice to other prospective third parties.
合伙企业Partnership
普通合伙企业的成立与合伙人身份认定Formation of General Partnership and Identification of Partners
普通合伙企业无需向州政府提交任何正式文件或进行登记即可成立。只要两人或两人以上为了营利而作为共同所有者共同经营某项生意，合伙企业即告成立。即使当事人主观上不打算成立合伙企业，其行为符合法定要件的，法律亦认定其成立。
A general partnership requires no formal filing or state registration to exist. It is formed whenever two or more persons associate to carry on as co-owners a business for profit. The law deems a partnership formed if the parties' conduct meets these criteria, even if they subjectively did not intend to create one.
在认定是否存在合伙关系时，共享生意利润是一项极其重要的推定依据。除非该项利润是以偿还债务、支付工资或租金等例外形式收取的，否则只要收取了利润，法律即推定其为合伙人。
Sharing of profits creates a rebuttable presumption that a person is a partner in the business. This presumption does not arise if the profits were received in payment of a debt, as wages, or as rent, which constitute specific legal exceptions.
甲和乙共同经营 ABC 生意。甲负责出资，乙负责运营，双方口头约定平分年终净利润。即便双方从未签署合伙协议，也未向政府登记，ABC 生意在法律上仍属于普通合伙企业。
A and B operate ABC Business together. A provides capital, and B manages operations. They orally agree to split net profits at year-end. Even though they never signed a partnership agreement or filed with the state, ABC Business is legally a general partnership.
利润分享推定的法定例外Statutory Exceptions to the Profit-Sharing Presumption
合伙企业财产Partnership Property
普通合伙企业是一个独立的法律实体。凡是用合伙企业资金购买的，或者以合伙企业名义受让的财产，均属于合伙企业财产，而不属于合伙人个人。合伙人对合伙企业财产不拥有独立的、可执行的个人所有权，其仅有为了合伙目的而使用该财产的权利。
A general partnership is a distinct legal entity. Property acquired with partnership funds or in the partnership's name belongs to the entity rather than to the individual partners. Partners have no personal, transferable interest in specific partnership property and may only use it for partnership purposes.
合伙人的对外代理权与日常业务范围Partner Authority and the Ordinary Course of Business
在法律上，每位合伙人都是合伙企业开展日常业务的代理人。合伙人为开展合伙企业日常业务而实施的行为，对合伙企业具有约束力，除非该合伙人事实上没有该项权利，且与其交易的第三人知道或收到了其没有该项权利的通知。
Each partner is an agent of the partnership for the purpose of its business. An act of a partner for apparently carrying on in the ordinary course the partnership business binds the partnership, unless the partner lacked actual authority and the third party knew or had received a notification that the partner lacked authority.
甲、乙、丙三人成立 ABC 合伙企业经营餐厅。甲在未通知乙和丙的情况下，向供货商订购了一批餐具。由于购买餐具属于该合伙企业的日常业务范围，即使甲在内部违反了约定，该采购行为对 ABC 合伙企业依然具有约束力。
A, B, and C form ABC Partnership to operate a restaurant. Without consulting B and C, A orders a shipment of tableware from a vendor. Because purchasing tableware is in the ordinary course of business for a restaurant, the transaction binds ABC Partnership even if A violated an internal agreement.
合伙人的个人责任与连带责任Personal Liability and Joint and Several Liability of Partners
普通合伙人对合伙企业在合伙存续期间所产生的所有债务和义务承担无限的、连带的个人赔偿责任。这意味着，如果合伙企业的资产不足以清偿债务，债权人可以直接追索任何一个普通合伙人的个人财产。
General partners are jointly and severally liable for all obligations of the partnership incurred during their tenure. Consequently, if partnership assets are insufficient to satisfy a judgment, creditors may seek satisfaction directly from the personal assets of any general partner.
新加入合伙人与退出合伙人的责任边界Liability Boundaries for Incoming and Outgoing Partners
新加入的合伙人对加入前合伙企业已经发生的债务不承担个人责任，其风险仅限于其向合伙企业投入的资本。相反，退出的合伙人对在其退出前合伙企业已经发生的债务仍需继续承担个人责任，除非债权人明示释放其责任。
An incoming partner is not personally liable for partnership obligations incurred before their admission; their risk is capped at their capital contribution. Conversely, an outgoing partner remains personally liable for partnership obligations incurred while they were a partner, unless released by the creditor.
甲、乙经营 ABC 合伙企业，对外欠债十万美元。此时丙作为新合伙人加入。三个月后，合伙企业因无力偿还该十万美元被起诉。债权人可以对 ABC 合伙企业的资产以及甲、乙的个人资产执行，但不能要求丙用个人资产偿还该笔加入前的债务。
A and B operate ABC Partnership, which owes one hundred thousand dollars to a creditor. C is then admitted as a new partner. Three months later, the creditor sues due to non-payment. The creditor can execute against partnership assets and the personal assets of A and B, but cannot reach C's personal assets for this pre-existing debt.
合伙人的信义义务Fiduciary Duties of Partners
合伙人对合伙企业及其他合伙人负有法定的信义义务，主要包括忠实义务和谨慎义务。忠实义务要求合伙人不得与合伙企业进行恶意竞争、不得篡夺合伙企业的商业机会、不得利用合伙企业财产谋取私利。谨慎义务则要求合伙人在管理业务时不得从事重大过失、鲁莽、故意违法或知情违约的行为。
Partners owe the partnership and other partners the fiduciary duties of loyalty and care. The duty of loyalty prohibits a partner from competing with the partnership, usurping partnership opportunities, or using entity property for personal enrichment. The duty of care restricts partners from engaging in grossly negligent, reckless, intentional misconduct, or knowing violations of law.
内部管理权与表决机制Internal Management Rights and Voting Mechanics
除非合伙协议另有约定，所有合伙人在管理日常业务时均享有同等的权利，不论其出资比例如何。对于日常业务中的争议，由过半数的合伙人表决决定；而对于改变合伙企业本质、修改合伙协议等非日常业务的重大事项，则必须经全体合伙人一致同意。
Unless otherwise provided in the partnership agreement, each partner has equal rights in the management and conduct of the ordinary business, regardless of capital contribution. Matters in the ordinary course of business require a majority vote of the partners, while extraordinary matters or amendments to the agreement require unanimous consent.
合伙企业分配、损益分担与补偿机制Partnership Distributions, Loss Allocation, and Indemnification
合伙企业的利润分配由合伙协议决定。如果协议未作约定，则全体合伙人平分利润。关于亏损的分担，若协议未作特别约定，则亏损的分担比例与利润分配比例完全相同。此外，如果某个合伙人为合伙企业的日常业务垫付了个人资金或承担了个人负债，合伙企业对其负有法定的补偿义务。
Profits are shared equally among partners unless the partnership agreement specifies otherwise. If the agreement is silent on losses, losses are shared in the exact same proportion as profits. Furthermore, a partnership must indemnify a partner for personal disbursements made or liabilities incurred in the ordinary course of the business.
甲出资百分之八十，乙出资百分之二十成立 ABC 合伙企业。双方未签署任何书面协议，也未口头约定如何分担盈亏。第一年结算时，合伙企业亏损十万美元。在法律上，甲和乙必须各自分担五万美元的亏损。
A contributes eighty percent of the capital and B contributes twenty percent to form ABC Partnership. They do not execute any agreement or discuss loss allocation. At the end of the first year, the partnership incurs a loss of one hundred thousand dollars. Legally, A and B must share the loss equally, meaning fifty thousand dollars each.
退伙与解散Dissociation versus Dissolution
退伙是指某个特定合伙人终止其与合伙企业的法律关系，例如合伙人自愿退出、死亡或被开除。退伙并不必然导致整个合伙企业的终止。解散则是指引发合伙企业停止营运并进入清算程序的法定事由（例如任意合伙企业中某个合伙人通知退出，或者合伙协议约定的期限届满）。
Dissociation occurs when a specific partner ceases to be associated with the carrying on of the partnership business (e.g., voluntary withdrawal, death, or expulsion). Dissociation does not automatically terminate the entity. Dissolution, however, is the legal event that triggers the winding up and ultimate termination of the partnership business (e.g., notice of withdrawal in a partnership at will, or expiration of a defined term).
清算程序与财产分配顺序Winding Up and the Order of Asset Distribution
在解散发生后，合伙企业必须进入清算阶段。在此期间，合伙企业的资产必须按照法定顺序处理：首先支付给债权人（包括外部债权人以及以债权人身份向合伙企业提供借款的合伙人）；随后，将清算产生的收益或损失记入各合伙人的资本账户；最后，剩余财产按照合伙人最终调整后的资本账户正余额进行分配。若某合伙人的资本账户为负数，该合伙人通常必须补足。
Upon dissolution, the partnership must wind up its affairs. Liquidation proceeds are handled in statutory order: first, creditors are paid, including outside creditors and partners who are creditors by reason of loans to the partnership; then liquidation gains and losses are credited or charged to the partners' capital accounts; finally, remaining assets are distributed to partners according to their final positive capital account balances. A partner with a negative capital account generally must contribute the deficiency.
有限合伙企业Limited Partnerships
有限合伙企业与普通合伙企业不同，其必须向州政府提交正式的“有限合伙企业证明书”方可成立。有限合伙企业包含两类截然不同的合伙人：至少有一名普通合伙人，对合伙企业债务承担无限的个人责任，并负责日常经营管理；以及至少有一名有限合伙人，其角色类似于被动的投资者，仅以其出资额为限承担有限责任，传统上不参与企业的日常管理。
Unlike a general partnership, a limited partnership must file a formal Certificate of Limited Partnership with the state registry to exist. It features two distinct classes of partners: at least one general partner, who manages operations and faces unlimited personal liability, and at least one limited partner, who acts as a passive investor, enjoys limited liability capped at their investment, and traditionally does not manage day-to-day operations.
有限责任合伙企业与有限责任隔离墙Limited Liability Partnerships and the Shield of Protection
有限责任合伙企业通常由律师、会计师等专业人士组建。它必须向州政府登记才能取得该项身份。有限责任合伙企业最大的特点在于其提供了“有限责任隔离墙”：任何合伙人均无需为其他合伙人在执业过程中所实施的疏忽、恶劣行为、违法操作或侵权行为承担个人的连带赔偿责任。但是，合伙人仍需为自己亲自实施的侵权行为或者其直接监督管理之下的下属所犯的错误承担个人责任。
A Limited Liability Partnership is typically utilized by professionals such as lawyers or accountants, and must file a statement of qualification with the state. The primary advantage of an LLP is its liability shield: no partner is vicariously liable for the negligent, wrongful acts, or misconduct committed by other co-partners. However, a partner remains personally liable for their own torts and the torts of anyone acting under their direct supervision.
公司Corporations
法人人格独立与公司设立Corporate Personhood and Formation
公司是一个独立于其所有者（股东）和管理者（董事与高级职员）的法定独立法人。公司享有起诉、被诉、拥有财产和签署合同的权利，并对其自身的债务承担独立责任。股东通常仅以其出资额为限承担有限责任。
A corporation is a legal entity distinct from its owners (shareholders) and managers (directors and officers). It possesses the capacity to sue, be sued, own property, and enter into contracts, and is solely liable for its own debts. Shareholders generally enjoy limited liability up to the amount of their investment.
设立章程与成立程序Articles of Incorporation and Formation Procedure
设立公司必须向州政府提交设立章程（或称公司注册证书）。章程必须包含：唯一的公司名称（须包含“公司”等字样）、法定的股份授权总数、设立人的姓名与地址，以及注册代理人的信息。当州政府正式接受并归档该章程时，公司正式成立。
To form a corporation, articles of incorporation (or a certificate of incorporation) must be filed with the state. The articles must include a unique corporate name (including an indicator like 'Corp.' or 'Inc.'), the maximum number of authorized shares, the names and addresses of incorporators, and registered agent information. Corporate existence begins upon filing by the state.
设立人责任与前期合同Promoter Liability and Pre-Incorporation Contracts
设立人是指在公司成立前，为公司筹集资金、购买资产或签署合同的人。除非合同另有明确约定，设立人对代表未成立公司签署的前期合同承担个人连带责任。即使公司随后成立并采纳了该合同，设立人的个人责任也不会自动解除，除非债权人、公司和设立人三方达成明示的债务更替协议。
A promoter is a person who acts on behalf of a corporation before it is formed, such as by raising capital, acquiring assets, or entering into contracts. Promoters are personally liable on pre-incorporation contracts unless the contract provides otherwise. The subsequent formation and adoption of the contract by the corporation does not automatically release the promoter; a novation is required.
甲代表尚未成立的 ABC 公司向乙购买办公楼，签署了买卖合同。随后 ABC 公司正式成立并入驻该办公楼。由于 ABC 公司未能支付房款，乙有权直接起诉甲要求其承担个人付款责任，因为双方并未签署债务更替协议。
A acts as a promoter for the unformed ABC Corporation and signs a contract with B to purchase an office building. After ABC Corporation is incorporated, it occupies the building. If ABC Corporation fails to pay, B can sue A personally because no novation occurred.
设立瑕疵：事实公司与表见公司Defective Incorporation: De Facto Corporation and Corporation by Estoppel
如果设立程序存在瑕疵导致公司未能合法成立，在诚信经营且不知情的情况下，当事人可以通过两种普通法抗辩免除个人责任：事实公司和表见公司。事实公司要求存在有效的成文法依据、当事人做出了善意的设立尝试、且实际行使了公司权力。表见公司则适用于与该组织进行交易的第三人，如果该第三人一直将其视为公司对待，则在诉讼中被禁止否认其公司地位。
If incorporation is defective, parties who acted in good faith without knowing the formation failed may escape personal liability via two common law doctrines: de facto corporation and corporation by estoppel. A de facto corporation requires a valid statute, a good faith attempt to comply, and an actual exercise of corporate powers. Corporation by estoppel bars a third party from denying corporate existence if they treated the entity as a corporation.
揭开公司面纱Piercing the Corporate Veil
为了防止欺诈或不公，法院可能会忽略公司的独立法人人格，要求股东对公司债务承担个人连带责任。通常情况下，单纯不遵守公司内部程序并不足以揭开面纱。法院在裁量时主要考察以下要素：
To prevent fraud or injustice, courts may look past the corporate form and hold shareholders personally liable for corporate obligations. Failure to follow corporate formalities alone is generally insufficient. Courts primarily weigh the following factors:
甲是 ABC 公司 的独资股东。甲直接用 ABC 公司 的银行账户支付个人房贷，且未保留任何财务账目。当 丙 在 ABC 公司 经营的店面内因疏忽受伤并赢得诉讼后，发现 ABC 公司 账户已被掏空。法院可准许 丙 揭开公司面纱，要求 甲 承担个人赔偿责任。
A is the sole shareholder of ABC Corporation. A pays his personal mortgage directly from ABC Corporation's bank account and keeps no separate books. C is injured due to negligence at the store run by ABC Corporation and wins a judgment, but ABC Corporation has no funds left. The court may allow C to pierce the corporate veil to collect from A.
资本结构与股份Capital Structure and Shares
公司的资本结构由其设立章程中所授权的股份决定。设立章程必须列明授权股份总数。已发行股份是指公司实际向股东卖出的股份；流通在外的股份则是指目前由股东持有的股份（不包括公司回购的库藏股）。股份可以分为普通股和享有分红或清算优先权的优先股。
A corporation's capital structure is determined by the stock authorized in its articles of incorporation. Authorized shares are the maximum number the corporation can issue. Issued shares are those sold to shareholders, and outstanding shares are those currently held by shareholders (excluding repurchased treasury shares). Shares may be divided into common shares and preferred shares with dividend or liquidation preferences.
股东投票、委托书与投票协议Shareholder Voting, Proxies, and Voting Agreements
除非设立章程另有规定，只有在法定股权登记日登记在册的股东才享有投票权。股东可通过签署书面委托书（代理投票权）授权他人代为投票。普通委托书在签署11个月后自动失效，且除非明确声明不可撤销并同时与一项财产或法律权益挂钩，或用于担保某项义务的履行（如股份购买权、质押权或债权人权益），否则委托人可随时任意撤销该委托。
Unless the articles provide otherwise, only shareholders of record on the record date are entitled to vote. A shareholder may vote shares in person or by executing a written proxy. A proxy is valid for 11 months unless otherwise provided and is freely revocable unless it explicitly states that it is irrevocable and is coupled with a legal or property interest, or given to secure performance of a duty, such as an option, pledge, or creditor interest.
表决权协议与表决权信托Voting Agreements and Voting Trusts
股东之间为了协调投票，可以签署书面表决权协议，该协议可由法院判令强制实际履行。此外，股东也可以设立表决权信托，将股份的法律所有权正式转移给信托受托人，该信托必须归档并对公众公开，且通常受法律规定的最长期限限制。
Shareholders may enter into a written voting agreement specifying how they will vote their shares; such agreements are specifically enforceable. Alternatively, shareholders may establish a voting trust by transferring legal title of their shares to a trustee. A voting trust must be filed with the corporation and is typically subject to statutory duration limits.
股东大会与非开会决议Shareholder Meetings and Action Without Meeting
公司必须每年召开一次股东年会以选举董事。董事会、章程授权人员或持有法定比例以上股份的股东可召集股东特别大会。公司必须在会前提前特定时间（通常为10至60天）书面通知股东开会的时间、地点，对于特别大会还必须说明会议目的。如果没有召开会议，股东必须通过全体一致书面同意（除非章程另有规定较低比例）才能通过决议。
Corporations must hold annual shareholder meetings to elect directors. Special meetings may be called by the board, authorized officers, or holders of a statutory percentage of shares. Shareholders must be given timely written notice (typically 10 to 60 days) of the time, place, and, for special meetings, the purpose. Action may be taken without a meeting only by unanimous written consent unless statutes or articles permit otherwise.
董事会：职权、法定人数与表决Directors: Board Authority, Quorum, and Voting
一切公司权力和业务运营必须由董事会管理或在其监督下进行。董事不享有单独代表公司签约的个人代理权，其必须作为一个整体共同行动。董事会做出有效决议的前提是会议召开时达到了法定人数（通常要求过半数董事在场）。决议必须获得在场董事的过半数赞成票。董事不能通过代理人（委托书）参加董事会投票。
All corporate powers and business affairs must be managed by or under the direction of the board of directors. Individual directors are not agents of the corporation and cannot bind it unilaterally. For the board to act, a quorum (generally a majority of total directors) must be present at the meeting. Action requires the affirmative vote of a majority of directors present. Directors cannot vote by proxy.
高级职员与表见代理Officers and Apparent Authority
高级职员（如总裁、秘书、财务总监）由董事会任命和罢免，负责执行公司的日常运营。高级职员作为公司的法律代理人，其权限适用普通代理法。如果公司向第三方表现出某位高级职员拥有特定职权，导致第三方产生合理信赖，则该高级职员的行为可能构成表见代理，进而约束公司。通常，公司总裁具有处理日常正常商业事务的默示职权，但无权处理重大非常规交易。
Officers (such as the president, secretary, and CFO) are appointed and removed by the board to handle daily operations. Officers are agents of the corporation, and their authority is governed by agency law. A corporation may be bound via apparent authority if it holds out an officer as having power and a third party reasonably relies on it. A president generally has implied actual authority for ordinary business actions, but not extraordinary ones.
ABC 公司 的总裁 甲 在未获得董事会正式授权的情况下，代表公司向 乙 订购了一批日常办公耗材。由于此类采购属于总裁的日常业务默示职权范畴，且 乙 拥有合理的第三方信赖，该合同对 ABC 公司 具有完全约束力。
A, the president of ABC Corporation, enters into a contract with B to buy ordinary office supplies without dynamic board approval. Because purchasing supplies falls within the implied actual or apparent authority of a president conducting routine operations, ABC Corporation is bound.
注意义务与商业判断规则Duty of Care and the Business Judgment Rule
董事和高级职员对公司负有信义义务。注意义务要求他们在履行职责时，必须保持诚信，并像一个普通的谨慎人在类似情形下一样尽到合理的注意和技能。在评估董事是否违反注意义务时，法院全面适用“商业判断规则”：这是一项反向推定，即推定董事是在知情、诚信且理性相信该决定符合公司最佳利益的基础上做出的商业决策。原告必须证明董事存在重大过失或不履职才能推翻该推定。
Directors and officers owe fiduciary duties to the corporation. The duty of care requires them to act in good faith and with the care that an ordinarily prudent person in a like position would exercise under similar circumstances. Under the Business Judgment Rule (BJR), courts presume that directors made their decision on an informed basis, in good faith, and with an honest belief that the action taken was in the best interests of the company. The plaintiff must show gross negligence to rebut this.
忠实义务、关联交易与公司机会Duty of Loyalty, Interested Director Transactions, and Corporate Opportunity
忠实义务要求董事和高级职员必须将公司的利益置于个人利益之上。商业判断规则不适用于涉及忠实义务和自我交易的诉讼。当董事与公司进行资产买卖等关联交易时，该交易原则上存在利益冲突而可被撤销，除非董事能证明交易条件完全公平，或者该交易在充分披露后获得了无利害关系董事过半数或无利害关系股东的批准。
The duty of loyalty requires directors and officers to prioritize the corporation's interests over their personal interests. The Business Judgment Rule does not shield self-dealing transactions. An interested director transaction is voidable unless the director demonstrates that the transaction was intrinsically fair to the corporation, or it was approved by a majority of disinterested directors or disinterested shareholders after full disclosure.
篡夺公司商业机会Corporate Opportunity Doctrine
董事和高级职员不得篡夺属于公司的商业机会。如果某一机会属于公司的业务线范围或公司对其有合理的预期，董事在个人利用该机会前，必须先向董事会全面披露并由董事会正式拒绝。如果董事未经披露便私自投资，公司有权要求其交出全部所得利润（拟制信托）。
Directors and officers are prohibited from usurping business opportunities that belong to the corporation. An opportunity belongs to the corporation if it is within the corporation's line of business or the corporation has an expectancy in it. A director must disclose the opportunity and allow the board to reject it before pursuing it personally. If violated, the corporation can seek a constructive trust to disgorge profits.
甲 是专门从事芯片研发的 ABC 公司 的董事。在一次行业会议上，他人向 甲 推荐了一个极具前景的全新芯片专利。甲 未将此事告知 ABC 公司，而是以个人名义买下该专利并转手获利。甲 违反了忠实义务中的公司机会原则，ABC 公司 有权索要其全部获利。
A is a director of ABC Corporation, a semiconductor microchip research firm. At a tech summit, a patent broker offers A a lucrative new chip patent. Without disclosing this to ABC Corporation, A buys the patent personally and resells it for profit. A violated his duty of loyalty, and ABC Corporation can disgorge his gains.
补偿与保险Indemnification and Insurance
当董事因公司职务被起诉时，法律区分了三种补偿情形：强制补偿、禁止补偿和自主补偿。如果董事在诉讼中成功胜诉（无论实体还是程序上），公司必须补偿其合理的律师费和诉讼支出。如果董事被法院认定对公司承担了直接责任，或者其行为涉及不当个人牟利，公司禁止对其进行补偿。在其他情况下，若董事主观出于诚信且合理相信其行为符合公司利益，公司可以自主选择给予补偿。公司亦可购买D&O保险来覆盖这些风险。
When a director is sued in their corporate capacity, indemnification falls into three categories: mandatory, prohibited, and permissive. A corporation must indemnify a director who is wholly successful on the merits or otherwise. A corporation is prohibited from indemnifying a director who is adjudged liable to the corporation or received an improper personal benefit. In other cases, a corporation may permissively indemnify if the director acted in good faith and reasonably believed their conduct was in the corporation's interest. Corporations may purchase liability insurance.
分红与财产分配Dividends and Distributions
发放分红的权力完全属于董事会的商业裁量权，股东无权强行要求分红。然而，董事会在宣布分红时必须遵守法定的资产清偿测试。如果发放分红会导致公司在日常商业中无法偿还到期债务（破产测试），或者导致公司总资产低于其总负债加优先清算权益（资产负债表测试），则禁止发放。投下赞成票的董事对违规分红承担个人连带赔偿责任。
The power to declare dividends rests entirely within the board's business discretion; shareholders have no absolute right to distributions. However, a board cannot declare a distribution if it violates statutory solvency tests: the corporation would be unable to pay debts as they come due in the ordinary course, or total assets would be less than total liabilities plus liquidation preferences. Directors who vote for an unlawful distribution are personally liable for the excess.
重大公司变更与估值异议权Fundamental Changes and Appraisal Rights
修改设立章程、合并、解散以及出售绝大部分资产等属于“重大公司变更”。完成此类变更通常需要：(1) 董事会采纳决议；(2) 向有权表决的股东发送专项通知；(3) 取得法定股东批准；(4) 向州政府归档变更文件。考试中要特别看清表决基数：传统规则常要求全体有权表决在册股份的过半数赞成；现代 MBCA 口径则常要求在达到法定人数的会议上，赞成票数多于反对票数。对上述变更持反对意见的特定股东，有权行使估值异议权，强制公司以公允价值现金回购其股份。
Fundamental corporate changes include amending the articles, mergers, dissolution, and selling substantially all assets. They usually require: (1) board approval of the transaction; (2) special notice to voting shareholders; (3) the required shareholder approval; and (4) filing the appropriate amendment, merger, or dissolution documents with the state. On an exam, watch the voting base: traditional statutes often require a majority of all outstanding shares entitled to vote, while the modern MBCA commonly requires votes cast in favor to exceed votes cast against at a meeting with a quorum. Dissenting shareholders may have appraisal rights, requiring the corporation to buy back their shares for fair cash value.
直接诉讼与派生诉讼Direct vs. Derivative Actions
股东起诉主要分为两类。直接诉讼是指股东针对自身受到的独特伤害（如剥夺表见投票权、拒绝查账）提起的诉讼，诉讼收益归股东个人。派生诉讼则是指股东代表公司向伤害公司的第三方（通常是违反信义义务的内部董事）提起诉讼，伤害直接作用于公司，股东仅受间接折损。派生诉讼获得的任何胜诉款项全部归入公司账户。
Shareholder suits are either direct or derivative. A direct action is brought for an injury suffered directly by the shareholder (e.g., denial of voting rights, inspection rights), and recovery goes to the individual. A derivative action is brought by a shareholder on behalf of the corporation for an injury done to the corporation itself (e.g., board breach of fiduciary duties). Any recovery flows back into the corporate treasury.
派生诉讼的必备前置程序Standing and Demand Requirements in Derivative Actions
提起派生诉讼的原告股东必须同时满足“同期持股”和“持续持股”：原告必须在被诉不当行为发生时就是股东，或因继承等法律转移取得股份；并且必须在整个诉讼过程中持续保持股东身份。此外，股东必须首先向董事会提交书面请求，敦促董事会自行起诉（前置催告）。根据 MBCA（通用规则），必须强制催告并等待90天，除非董事会提前拒绝。而在某些特拉华州规则中，如果原告能证明董事会多数成员存在重大利益冲突，可豁免催告（催告徒劳例外）。
To bring a derivative suit, the plaintiff must satisfy both contemporaneous and continuous ownership: the plaintiff must have been a shareholder when the challenged conduct occurred, or have received the shares by operation of law such as inheritance, and must continue to hold shareholder status throughout the litigation. The shareholder must also make a written demand on the board to bring suit. Under the MBCA, universal demand is required and the shareholder must wait 90 days unless the demand is rejected earlier. Delaware law may excuse demand if the plaintiff proves demand futility due to disabling director conflicts.
闭锁公司与特别治理Closely Held Corporations
闭锁公司是指股东人数极少且股票不在公开市场交易的公司。这类公司的内部治理更类似于合伙企业。法律允许闭锁公司股东签署股东协议，直接限制董事会权力、甚至完全取消董事会并由股东直接经营。由于其股份缺乏流动性，闭锁公司多数股东对少数股东负有类似于合伙人之间的、极高标准的绝对诚信义务。如果多数股东存在压榨行为，少数股东可请求法院强制解散公司或强制实施股权收购。
A closely held corporation has few shareholders and no public market for its shares. Internal governance functions similarly to a partnership. Shareholders may execute an agreement under the MBCA that alters or abolishes the board of directors in favor of direct shareholder management. Because shares lack liquidity, majority shareholders owe minority shareholders a heightened fiduciary duty of utmost good faith. In case of oppression, minority shareholders can petition for dissolution or a mandatory buyout.
LLCLLC
有限责任公司的概念与设立Nature and Formation of an LLC
有限责任公司（LLC）是一种非法人商事组织，它结合了公司（股东有限责任）与合伙企业（穿透式税收和运营灵活性）的独特优势。设立 LLC 必须向州级主管机关（通常为州务卿）提交组织章程（Articles of Organization 或 Certificate of Formation）。
A Limited Liability Company (LLC) is an unincorporated business entity that combines the corporate advantage of limited liability with the partnership advantages of pass-through taxation and operational flexibility. Formation requires filing Articles of Organization (or a Certificate of Formation) with the designated state official, typically the Secretary of State.
甲和乙决定成立 ABC LLC。他们签署了内部协议，但忘记向州务卿提交组织章程。此时 ABC LLC 并未依法成立，甲和乙可能需要承担无限连带责任。
A and B decide to form ABC LLC. They sign an internal agreement but forget to file the Articles of Organization with the Secretary of State. ABC LLC is not validly formed, and A and B may face unlimited joint and several liability.
运营协议的地位The Role of the Operating Agreement
运营协议是成员之间管理公司内部事务的核心契约。虽然多数州不要求运营协议必须采用书面形式或向州政府备案，但它是调整成员权利义务的首要依据。若运营协议未作约定，则适用州法的默认规则。
The operating agreement is the core contract among members governing the internal affairs of the company. While most states do not require it to be in writing or filed with the state, it serves as the primary source of governance. Where the agreement is silent, state statutory default rules apply.
管理模式与代理权限Governance Models and Agency Authority
除非组织章程或运营协议另有约定，现代 LLC 默认由成员共同管理（成员管理型）。如果协议明确约定，则可交由专职经理管理（经理管理型）。
Unless otherwise provided in the articles of organization or the operating agreement, a modern LLC is presumed to be member-managed. If specified in the agreement, it can be manager-managed.
成员管理型 LLCMember-Managed LLC
在成员管理型 LLC 中，管理权属于全体成员。通常情况下，每位成员在日常商业事务中享有同等的管理权；但在现代 LLC 法下，成员并不会仅因“成员身份”自动成为 ABC LLC 的代理人。对外缔约权限仍应依据普通法代理规则、运营协议以及 ABC LLC 向第三人作出的表示判断。对于超出日常业务的重大事项，则通常需要绝对多数或全体成员同意。
In a member-managed LLC, management rights belong to all members. Each member typically has equal rights in ordinary business affairs, but under modern LLC statutes a member is not automatically an agent of ABC LLC merely by being a member. Authority to bind the LLC must still be established through ordinary agency principles, the operating agreement, or manifestations made by ABC LLC to the third party. Extraordinary matters usually require majority or unanimous member consent.
经理管理型 LLCManager-Managed LLC
在经理管理型 LLC 中，管理权专属授予经理（经理可以由成员担任，也可以由非成员担任）。普通成员不享有管理权，在日常业务中通常也没有代理公司对外缔约的权限。经理的对外权限同样要结合运营协议、职位授权以及 LLC 对第三人的表示判断；若这些依据存在，经理才可能使 LLC 受日常业务合同约束。
In a manager-managed LLC, management authority is vested in the managers, who may or may not be members. Regular members do not have management rights and usually lack authority to bind the firm in ordinary transactions. A manager's external authority is still evaluated by reference to the operating agreement, the manager's role, and manifestations made by the LLC to the third party; where those bases exist, the manager may bind the LLC in ordinary business contracts.
ABC LLC 在其运营协议中约定为经理管理型，并聘请丙担任经理。成员甲在未经丙授权的情况下，擅自代表 ABC LLC 向丁购买了一批办公设备。若丁知晓该 LLC 为经理管理型且甲非经理，则该购买行为对 ABC LLC 不发生法律效力。
ABC LLC specifies in its operating agreement that it is manager-managed and appoints C as manager. Member A, without authorization from C, enters into a contract to purchase office equipment from D on behalf of ABC LLC. If D knows that the LLC is manager-managed and that A is not a manager, the contract does not bind ABC LLC.
有限责任与揭开公司面纱Limited Liability and Piercing the Veil
LLC 的基本特征是成员与经理的有限责任。作为独立法人，LLC 自身的债务和责任应由公司财产独立承担。成员仅以其出资额为限对公司承担责任。但是，若发生欺诈、严重资本不足、财产高度混同等情形，法院可参照公司法规则“揭开公司面纱”，判令成员承担个人责任。需要注意的是，LLC 内部程序的不合规（如未召开会议）通常不能作为揭开面纱的独立理由。
The foundational feature of an LLC is the limited liability of its members and managers. As a distinct legal entity, the LLC is solely responsible for its own debts and obligations. Members risk only their capital contributions. However, courts may "pierce the LLC veil" to impose personal liability under corporate law analogies, such as fraud, severe undercapitalization, or pervasive commingling of assets. Notably, failure to observe organizational formalities (like holding meetings) is generally not a ground for piercing the veil in an LLC context.
信义义务及其调整Fiduciary Duties and Modification
具有管理权的组织控制者（成员管理型中的各成员，或经理管理型中的各经理）对公司及其他成员负有忠实义务（Duty of Loyalty）和勤勉义务（Duty of Care）。
Those who possess management control (members in a member-managed LLC, or managers in a manager-managed LLC) owe fiduciary duties of loyalty and care to the entity and its other members.
财务结构与财产权益的转让Financial Structure and Transferability of Interests
在高级别财务层面上，LLC 默认享受“穿透式”税收待遇（Pass-through Taxation）。这意味着 LLC 实体本身无需缴纳联邦所得税，其利润或亏损直接分配并转嫁至各成员的个人税单中，从而避免了传统公司的“双重征税”。
At a high level, an LLC defaults to "pass-through" tax treatment. This means the LLC entity itself pays no federal income tax; instead, profits and losses flow directly through to the individual tax returns of the members, avoiding the double taxation encountered by standard corporations.
成员在 LLC 中拥有的财产权（分配利润的权利）可以自由转让给第三方。然而，成员的管理权（表决权、参与管理权）属于人身权，未经全体其他成员一致同意，不得随同转让。受让人在获得一致同意前，仅为利益受让人，无权参与公司经营。
A member's financial interest (the right to receive distributions) is freely transferable to a third party. However, a member's management interest (voting and participation rights) is personal and cannot be transferred without the unanimous consent of the remaining members. Prior to such consent, the transferee is merely an assignee/transferee of financial rights and has no right to manage the business.
甲是 ABC LLC 的成员。甲在未征得其他成员同意的情况下，将其在公司中的全部“成员权益”转让给了丙。丙仅有权收取甲原本应得的利润分配，但丙无权就公司事务进行表决，也无权查阅公司账簿，除非其他成员一致同意接纳丙为全面成员。
A is a member of ABC LLC. Without the consent of other members, A transfers all of his "membership interest" to C. C is only entitled to receive the financial distributions A would have received; C has no right to vote on company affairs or inspect corporate books unless all other members unanimously agree to admit C as a full member.
退股、解散与清算Dissociation, Dissolution, and Winding Up
成员可以通过向公司发出通知随时退出（退股/Dissociation）。虽然成员拥有退出的权力，但如果该退出违反了运营协议的约定，则属于违约退出，须向公司承担损害赔偿责任。在现代 LLC 法下，单一个别成员的退股通常不再直接触发整个公司的强制解散。
A member has the power to dissociate at any time by giving notice to the company. While a member always has the power to dissociate, doing so in violation of the operating agreement constitutes a wrongful dissociation, making the member liable for damages. Under modern LLC statutes, the dissociation of a single member no longer automatically triggers dissolution of the entire entity.
LLC 的解散（Dissolution）会导致公司进入清算（Winding Up）阶段。导致解散的事由通常包括：运营协议约定的解散期限届满或事件发生、全体成员一致同意、或由于管理僵局或欺诈等原因由法院判决司法解散。在清算期间，公司资产必须首先用于清偿债权人（包括属于债权人的成员），剩余资产再依照成员的出资及比例进行内部结算与分配。
Dissolution of an LLC commences the winding-up phase. Triggering events for dissolution generally include the expiration of a term or event specified in the operating agreement, unanimous consent of the members, or a judicial decree of dissolution due to management deadlock or oppressive conduct. During winding up, assets must first be applied to discharge obligations to creditors (including members who are creditors) before remaining assets are distributed internally to members.
