Definition
A claim is a demand or assertion of a right — a party's assertion that they are entitled to something from another person, an institution, or a legal system. The term operates across virtually every field of law and carries distinct meanings depending on context.
1. In civil procedure and litigation: A claim is the legal theory or cause of action upon which a party seeks relief. It is the assertion that the defendant's conduct (or failure to act) has caused harm for which a remedy — damages, injunctive relief, or other relief — is available under law. Under modern procedural rules, a "claim for relief" is the foundational unit of a complaint.
2. In property law: A claim is an assertion of ownership, title, or possessory right to real or personal property. This includes adverse possession claims, mineral claims, and competing title claims. Historically, the term frequently appeared in land law to describe unproven or contested title.
3. In the law of obligations and debt: A claim is a creditor's demand for payment of money owed, whether arising from contract, tort, or statute. In bankruptcy proceedings, a "proof of claim" is a creditor's formal assertion of the amount owed to them from a debtor's estate.
4. In public law and administrative law: A claim is a formal demand submitted to a government body — a benefits claim, a tax refund claim, or a claims act petition. Veterans' benefits claims, insurance claims, and tort claims against government entities all fall within this usage.
5. In patent law: A claim is the precisely worded statement at the end of a patent application defining the scope of the patent's legal protection. Patent claims are the operative legal text of a patent; they determine what is and is not protected.

Common Language
Modern common usage (Wiktionary): A demand for something as rightful; an assertion that something is true; the thing demanded or asserted.
Historical common usage (Webster's 1913): "A demand of a right or supposed right; a calling on another for something due or supposed to be due; as, a claim of wages for services." Also: "A right to claim or demand something; a title to any debt, privilege, or other thing in possession of another; as, to have a claim on a man for services rendered."
The ordinary English meaning — a demand or assertion — maps closely to the legal meaning's surface. The gap lies in precision and consequence. In law, not every assertion is a cognizable claim; a claim must be legally actionable, grounded in a recognized cause of action or right. Calling something a "claim" in conversation carries no procedural or legal weight; calling something a "claim" in litigation triggers duties to respond, procedural timelines, and potential liability.

Common Confusion
Claim vs. Cause of Action: These terms are often used interchangeably but carry a technical distinction in some contexts. A cause of action is the legal theory or set of elements that, if proven, entitles a party to relief (e.g., negligence, breach of contract). A claim is the assertion that those elements are met in a particular dispute. In practice, many courts and practitioners use them synonymously, and modern federal pleading standards (notice pleading) have softened any rigid distinction. Historical sources, however, tend to treat "cause of action" as the more precise term and "claim" as its broader, more colloquial equivalent.
Claim vs. Right: A claim is an asserted right — it may or may not be recognized by law. A right, in legal usage, is a protected interest already established. The distinction matters: a party may have a claim without ultimately having a right, and the litigation process exists in part to determine which claims become enforceable rights.

Why It Matters in Research
CLAIM is one of the most pervasive and context-sensitive terms in the entire legal corpus, which creates real traps for researchers.
First, jurisdictional and doctrinal context governs meaning. A "claim" in a bankruptcy docket has a specific statutory definition. A "claim" in a patent file has an entirely different technical meaning. A "claim" in a veterans' benefits file triggers a distinct regulatory framework. Treating any of these as interchangeable with the litigation sense produces errors.
Second, historical sources use the term with more elasticity than modern sources. Rapalje & Lawrence and contemporaneous treatises frequently use "claim" and "demand" as near-synonyms, and the procedural distinction between a claim and a cause of action was less developed under common law pleading than under modern rules. When reading 19th-century cases or treatises in the corpus, expect looser usage.
Third, the shift from common law pleading (with its formal forms of action) to code pleading and then to notice pleading under modern federal rules changed what "stating a claim" requires. Corpus materials from different eras reflect different standards; a 19th-century discussion of whether a declaration states a claim is procedurally different from a 20th-century motion to dismiss for failure to state a claim.
Fourth, administrative and government claims operate under separate regimes. For researchers working in veterans law, the pathway from initial claim to rating decision to appeal is governed by statutes and regulations that define "claim" in specific and sometimes counterintuitive ways. The Law Mind Military, Veterans & Admiralty Law Encyclopedia entry on the VA Claims Process is the right starting point for that context.
Fifth, in patent research, the word "claim" is a term of art with near-mathematical precision. Historical patent law materials in the corpus show the gradual formalization of claim drafting as a practice; early patent instruments often lack the structured independent/dependent claim format that became standard.

Historical Dictionary Support
Rapalje & Lawrence define a claim broadly as a demand for something as one's due, or a title to any debt or property held by another, encompassing both the demand itself and the underlying right asserted. Their treatment is consistent with the general common law usage of the era and does not sharply distinguish between claims in the litigation sense and claims in the property or debt sense — all are unified under the concept of an asserted entitlement.
What Rapalje & Lawrence do not address, and what the historical dictionary literature broadly misses, is the procedural significance of "claim" that modern practice has elevated. The transformation of "claim" into the foundational unit of civil litigation — the thing a complaint must plead, the thing a motion to dismiss targets — is a product of 20th-century procedural reform. Researchers relying solely on 19th-century dictionary definitions will find accurate descriptions of the word's substance but no guidance on its procedural function under modern rules.
Historical sources also do not address patent claims as a distinct category in any meaningful way, and they predate the development of administrative claims practice as it exists under modern regulatory states. The corpus materials must be read with awareness of these gaps.

Jurisdictional Note
The procedural meaning of "claim" varies between federal and state courts, and among states that have not adopted rules modeled on the Federal Rules of Civil Procedure. In federal court, Rule 8 governs what a claim for relief must contain. Some states retain code pleading traditions that impose different requirements. In veterans' benefits and other federal administrative contexts, "claim" carries specific statutory definitions that control the administrative process regardless of how courts use the term in other contexts.
