Modern jurisdictions have largely abolished or sharply limited the doctrine so that the parent-child relationship alone does not create tort immunity.

A common-law doctrine that barred an unemancipated minor from suing a parent for ordinary negligence arising out of the exercise of parental authority, supervision, or discretion within the family relationship. The rule rested on preserving family harmony and parental autonomy. Modern authority has largely repudiated any blanket bar based solely on the parent-child relationship.

A legal status that confers rights and obligations between a parent and child. This status requires consent from both biological parents for adoption unless rights have been terminated or consent is waived after notice and hearing. It also determines standing in custody proceedings and bars certain parties from altering the relationship through arbitration or donor agreements without formal compliance.

An oral agreement that discharges all unperformed duties under an existing contract.

An agreement formed by spoken words or conduct rather than a complete signed writing. At common law the term also denotes any contract not executed under seal even if reduced to writing.

A substantive rule of law that renders inoperative prior or contemporaneous agreements, whether oral or written, to the extent they contradict or add to the terms of a completely integrated written agreement.

A substantive rule of contract law that renders prior agreements inoperative to the extent they contradict or add to a completely integrated writing. The court determines as a preliminary matter whether an agreement is integrated and the degree of integration before applying the rule. The doctrine does not bar evidence offered to show fraud, illegality, or to interpret ambiguous terms.

The proof may be admitted when it shows fraud, mistake, collateral agreements, or donor intent.

Oral testimony offered to prove the terms of an agreement or the true character of a transaction. Courts admit the testimony when a writing is not completely integrated or when offered to show that an absolute deed was intended only as security for a debt.

A trust created by oral declaration of the settlor rather than by a written instrument. The existence of the trust and its material terms must be established by clear and convincing evidence unless another statute requires a writing.

Technical words or phrases peculiar to legal discourse and instruments.

A party to an action. The term identifies any person or entity that participates in litigation as plaintiff, defendant, or intervenor.

A contractual provision or preliminary communication that forms part of the parties' final agreement. Such a provision becomes binding when the parties manifest assent to it as an element of their exchange, whether through incorporation into a later offer or through conduct recognizing the existence of a contract.

A prerequisite for the creation of an express warranty under the Uniform Commercial Code that an affirmation of fact, promise, description, or sample must satisfy to bind the seller. The requirement focuses on whether the seller's statement or representation was a material factor in the buyer's decision to enter the transaction.

An equitable doctrine that permits enforcement of an oral contract or restitution for benefits conferred when a party has rendered part performance in reliance on the agreement. The doctrine satisfies the evidentiary purpose of the statute of frauds or creates an option contract that renders a unilateral offer irrevocable while performance continues. It applies when the acts are unequivocally referable to the contract and the performing party cannot be restored to the status quo without injustice.

An equitable exception to the statute of frauds that permits enforcement of an oral contract when a party has substantially performed in reliance on the promise. Courts typically require acts such as payment of part or all of the purchase price, taking possession of the property, or making substantial improvements that are unequivocally referable to the contract. The doctrine prevents the statute from being used as an instrument of fraud when the performing party's conduct corroborates the existence of the agreement.

An exception to the statute of frauds that permits recovery in restitution for benefits conferred by part performance when a contract has been avoided on grounds such as mistake or misrepresentation. The claim is not treated as an action upon the contract. The rule applies after avoidance on any statutory ground and allows recovery of the reasonable value of improvements or other benefits conferred.

An action or proceeding conducted without notice to or participation by the opposing party. The phrase describes any judicial, administrative, or transactional step taken when one side remains unheard because no opportunity for response was afforded.

A claim for damages based on only part of the injured party's remaining rights to performance under the contract. The claim leaves the overall agreement in force and seeks compensation limited to the specific shortfall rather than the value of all unperformed obligations.

A mental condition short of full insanity under which evidence of the defendant's mental abnormality is admissible to determine whether the mental state required as an element of the charged offense was present.

An integrated agreement other than a completely integrated agreement. Extrinsic evidence of consistent additional terms may be admitted to supplement the writing but not to contradict its terms.

A basis for restitution allowing a party who has conferred benefits through part performance of an avoided contract to recover the value of those benefits from the other party. The doctrine also supplies an exception to the statute of frauds when the conduct unequivocally refers to the alleged agreement and prevents injustice.

A principal in an agency relationship when the third party knows that an agent is acting for some principal but lacks notice of the principal's identity. The principal remains liable on authorized contracts made by the agent.

A classification of principal in agency law under which the third party knows that an agent is acting for some principal but lacks notice of the principal's identity. The classification determines the principal's liability on the agent's authorized contracts and the agent's personal liability alongside the principal. It occupies the middle ground between a disclosed principal whose identity is known and an undisclosed principal whose existence is unknown.

A principal in an agency relationship when the third party has notice that the agent acts for a principal but lacks notice of the principal's identity. The principal remains bound on authorized contracts made by the agent.

An integrated agreement other than a completely integrated agreement. The writing serves as the final expression of some but not all terms of the parties' deal.

An integrated agreement other than a completely integrated agreement. The writing serves as a final expression of the terms it addresses but leaves room for consistent additional terms not covered in the document.

An integrated agreement other than a completely integrated agreement. The writing serves as the final expression of the terms it contains but does not preclude proof of consistent additional terms reached during negotiations.

A participant in a legal transaction, proceeding, or relationship. The term identifies one who joins in the relevant conduct or arrangement and thereby incurs the associated rights or obligations under the governing rule.

A participant in the commission of a criminal offense who aids or encourages its commission and thereby becomes legally accountable for the conduct of the principal actor. The term encompasses both direct assistance with the purpose of promoting the offense and failure to fulfill a legal duty to prevent it when that failure is accompanied by the requisite culpability. Conviction as a particeps criminis requires proof of the underlying offense and the defendant's complicity, even if the principal has not been prosecuted or convicted.

A standard of involvement that triggers disqualification from later representation in the same matter. Direct hands-on work on a discrete controversy involving specific parties meets the threshold when the lawyer exercises independent judgment and shapes outcomes.

An act of taking part in an activity, proceeding, or transaction. The concept requires active involvement that contributes to the outcome or decision at issue.

Liability imposed on a person who aids, encourages, or facilitates another's commission of a crime with the purpose of promoting or facilitating the offense. The doctrine reaches conduct that would establish complicity if the crime were completed and extends to inchoate forms such as attempt to aid or solicitation even when the principal never acts.

A specific, quantifiable loss that a plaintiff must plead with particularity and prove as a legal consequence of the defendant's conduct.

Compensatory damages awarded for harms other than those that ordinarily flow from the wrongful act. Recovery requires specific pleading and proof that the losses were caused by the conduct, were reasonably foreseeable, and could not have been avoided.

An injury that is concrete and particularized to the plaintiff. The injury must affect the plaintiff in a personal and individual way rather than constituting a generalized grievance shared equally by all citizens.

A specific subject or issue to which a portion of manifested intention or assent relates. The concept identifies the discrete topic that determines the reach of authority, contractual terms, or professional obligations.

A concept in defamation law identifying the specific controversy into which a person has voluntarily injected himself, thereby becoming a limited-purpose public figure subject to the actual-malice standard on that issue.

A specific use for which the buyer requires the goods that is known to the seller at contracting. The seller's knowledge of that use plus the buyer's reliance on the seller's skill or judgment creates an implied warranty that the goods will be fit for the use.

A requirement applied to subpoenas that the scope of documents or information demanded must not harass or oppress the recipient to the point of causing unreasonable business detriment. Courts assess this prong by weighing the volume, time span, and operational impact of compliance against the needs of the investigation.

An injury that affects the plaintiff in a personal and individual manner rather than as a member of the general public. The harm must be concrete and distinct to the plaintiff instead of a diffuse grievance shared equally by all citizens.

A concrete demonstration of harm to the defense that a defendant must ordinarily prove to obtain relief from certain constitutional violations. Structural errors such as the erroneous disqualification of chosen retained counsel relieve the defendant of any obligation to make this showing because the violation itself distorts the framework of the trial.

A requirement that legal authorizations and pleadings identify the place, persons, things, or matters involved with sufficient specificity to prevent ambiguity or overbreadth. The description must enable the executing party to ascertain the precise scope without resort to external documents or guesswork. Failure to meet the standard renders the authorization or pleading defective.

The individuals or entities who assert claims or defend against them in a judicial proceeding.

A legal relationship between parties that arises from contract, property transfer, or succession and permits rights or obligations to be enforced between them or to run with the land. The relationship supplies the connection required for one party's duties or benefits to bind or benefit the other after a transfer or in successive use. It exists in distinct forms such as privity of contract and privity of estate.

The division of real property held jointly or in common by co-owners into individually owned interests. The division may occur through physical allocation of parcels or through a judicial sale followed by distribution of the proceeds among the former co-owners.

A judicial proceeding in which one or more co-owners of property compel division of their undivided interests. The court first considers whether the property can be physically divided into separate parcels of comparable value and utility. When physical division would be inequitable because of the land's characteristics or external legal constraints such as zoning or water-rights rules, the court may instead order a sale and divide the proceeds among the co-owners according to their respective interests.

A judicial proceeding by which a co-tenant may compel the division of property held in concurrent ownership either by physical allotment of separate parcels or by sale with division of proceeds.

A method of dividing co-owned real property into physically distinct parcels that are separately titled and allocated to each co-owner according to their interests.

A judicial remedy available to co-tenants by which a court orders the sale of commonly owned real property and the division of sale proceeds among the owners. The remedy is available when a fair and equitable physical division of the land cannot be accomplished because of the property's physical characteristics or external legal constraints such as zoning rules that would render resulting parcels unusable or unbuildable.

A method of dividing commonly owned real property by physically separating the land into distinct parcels awarded to each co-tenant. Each former co-tenant receives fee simple title to a separate portion rather than retaining an undivided interest in the whole. Courts favor this approach when the land's physical features and any legal restrictions permit an equitable allocation without rendering parcels unusable.

A judicial action in which co-owners of real property seek to terminate their concurrent estate by obtaining a court order for physical division of the land or, if that is impracticable, for sale of the property with division of the proceeds.

A judicial remedy ordering the sale of co-owned real property with division of proceeds when a fair physical division among cotenants cannot be made. Physical characteristics of the land or external legal constraints such as zoning rules that render separate parcels unusable can justify the sale instead of partition in kind.

A judicial remedy in which a court orders the sale of property held by co-tenants and divides the proceeds among them when physical division of the land is impractical or inequitable. Physical characteristics of the land and external legal constraints such as zoning requirements that render separate parcels unusable can justify the sale instead of division in kind.

A judicial proceeding brought by one or more co-tenants to divide jointly owned real property either by physical allotment of separate parcels or by sale with division of the proceeds.

An association of two or more persons who carry on a business as co-owners for profit. Existence of a partnership is presumed when the persons agree to share profits or losses proportionally.

Dissolution occurs when the partnership receives notice of a partner's express will to withdraw, effective on the date specified in the notice if later than receipt.

A payment of cash or property made by a partnership to one of its partners from earnings, as an advance on future earnings, or in partial or complete liquidation of the partner's interest. The default rule requires that such distributions be shared equally among the partners unless the partnership agreement provides otherwise or a charging order redirects payment.

A partnership formed for a fixed duration or to accomplish a specific undertaking. The arrangement imposes a temporal limit that distinguishes it from an at-will partnership and triggers special rules governing dissociation before the agreed endpoint.

A partnership structure derived from civil law in which one or more general partners manage the business and bear unlimited personal liability while one or more limited partners contribute capital, take no part in management, and risk only the amount of their investment.

The event by which a person ceases to be a partner or member in a partnership or limited liability company.

Evidence sufficient on its face to establish a fact or to shift the burden of production unless the opposing party introduces contrary proof.

An evidentiary threshold that requires a party to produce evidence sufficient, if unrebutted, to support a particular conclusion or finding. The showing shifts the burden of production to the opposing party, which must then introduce contrary evidence or risk an adverse determination. The standard does not shift the ultimate burden of persuasion.

An item that a statute or rule declares presumptively authentic. The presumption relieves the proponent of producing extrinsic evidence of genuineness before the item is admitted.

A rule of law that requires a certain result unless the party adversely affected produces evidence to overcome it. The presumption shifts only the burden of production and remains subject to rebuttal by contrary proof.

A limited search conducted by officers incident to an in-home arrest of areas beyond the arrestee's immediate control when officers possess a reasonable belief based on specific and articulable facts that the area harbors an individual posing a danger. The sweep must be cursory and confined to places where a person could hide.

A foundational principle of Fourth Amendment jurisprudence holding that constitutional protection extends to individuals' reasonable expectations of privacy rather than to particular physical locations.

A doctrine mitigating an intentional killing from murder to voluntary manslaughter when the defendant acts in the heat of passion upon adequate provocation before a reasonable cooling-off period has elapsed. Adequate provocation requires that the provocation would arouse sudden intense passion in an ordinary person, that the defendant was actually provoked, that a reasonable person would not have cooled, and that the defendant did not cool.

A common-law doctrine that reduces an intentional killing from murder to voluntary manslaughter when the defendant acts in the heat of passion upon adequate provocation and before a reasonable cooling-off period has elapsed. Adequate provocation must be of a type that would arouse sudden and intense passion in an ordinary person, the defendant must have been actually provoked, and the defendant must not have cooled off before the killing. Certain situations such as a serious battery on the defendant or a close relative or discovering a spouse in the act of adultery qualify as adequate provocation while mere words, trivial battery, and old wrongs do not.

A causal connection between an actor's tortious conduct and harm to another that the law deems sufficient to impose liability on the actor. The connection exists when the actor's conduct is a substantial factor in bringing about the harm and no superseding cause or defense severs responsibility.

A causation standard that limits liability to harms sufficiently connected to the defendant's conduct. The test requires more than factual causation and examines whether the harm was a foreseeable or direct result of the act or omission.

A test for determining whether conduct constitutes criminal attempt under which the defendant's overt act must come dangerously close to completing the target offense. Mere preparation remains insufficient. The act must stand in close physical and causal proximity to the completed crime so that the offense would have occurred but for an interruption.

A common-law doctrine for determining attempt liability that requires the defendant's overt act to come dangerously close to completing the target offense. The test distinguishes mere preparation from perpetration by focusing on physical and causal proximity to the completed crime. Conduct remains insufficient if substantial steps are still undone even when the defendant possesses clear intent and tools.

A doctrinal test used to determine whether a defendant's conduct has progressed far enough to support liability for attempt. The test requires that the defendant's overt act come dangerously close to completing the target offense, going beyond mere preparation and approaching the point of consummation.
