Definition
The performance of an obligation to pay money, or, in some contexts, the delivery of something accepted in lieu of money, by which a debt or duty is discharged. Payment is the ordinary mode of extinguishing a monetary obligation: the debtor tenders what is owed, the creditor receives it, and the obligation is satisfied.
Several distinct legal meanings operate under this single term:
1. Discharge of a monetary debt. The transfer of money (or money's equivalent) from debtor to creditor in the amount and manner required by the obligation. To constitute a valid payment, the sum paid must correspond to the amount due, the tender must be made to the proper party, and the creditor must accept it.
2. Satisfaction by substitute. Courts have long recognized that a creditor may agree to accept something other than money — goods, services, a negotiable instrument — in full satisfaction of a debt. This is sometimes called payment by accord and satisfaction, though it technically merges with that doctrine.
3. Payment as a plea or affirmative defense. In pleading, "payment" is a distinct defense asserting that the obligation sued upon has already been discharged. The defendant bears the burden of proving it.
4. Constructive or involuntary payment. A payment compelled by legal process — for example, a levy or garnishment — still discharges the underlying obligation, even though it lacks the voluntariness of ordinary payment.

Common Language
Modern common usage (Wiktionary): The act of paying, or giving compensation; the discharge of a debt or an obligation.
Historical common usage (Webster's 1913): The act of paying, or giving to a party that which is due, whether it be money, goods, or service; discharge of a debt or obligation.
The common and legal meanings are closely aligned in ordinary use. The legal gap emerges in specifics: common usage treats payment as essentially any transfer satisfying a debt, while law scrutinizes whether payment was made to the right party, in the right form, at the right time, and whether it was accepted. A payment made to an unauthorized agent, or by a check that is later dishonored, may not legally discharge the obligation even though it looks like payment in everyday terms.

Common Confusion
Payment vs. Tender. Tender is the offer to pay; payment is the completed act. A valid tender, if refused, stops the running of interest and may shift costs, but it does not itself discharge the debt. Researchers in older equity sources should be careful: "tender and payment" sometimes appear as a compound phrase where only tender was actually made.
Payment vs. Accord and Satisfaction. Payment discharges a liquidated, undisputed debt in full. Accord and satisfaction resolves a disputed or unliquidated claim by agreement to accept something different or less. Historical sources sometimes blur these — particularly where a creditor accepts a partial payment "in full satisfaction" — and courts have divided on whether that transaction is payment, accord and satisfaction, or neither.

Core Elements
For payment to discharge an obligation, the following must generally be established:
1. Proper party. Payment must be made to the creditor or to an agent authorized to receive it. Payment to an unauthorized third party does not discharge the debt, even if the creditor never receives the funds.
2. Proper amount and form. Payment must be in the amount due. Partial payment discharges the debt only to the extent of the amount paid, unless the creditor agrees to accept it in full satisfaction.
3. Acceptance. The creditor must receive and accept the payment. Where a creditor wrongfully refuses a valid tender, the obligation's character may be affected (interest ceases to run), but technical discharge generally requires actual receipt or a court's intervention.
4. Intent to apply. Where a debtor owes multiple debts to the same creditor, the debtor may direct application of a payment to a specific debt. If the debtor does not direct, the creditor may apply it as the creditor chooses. If neither directs, courts apply it according to equitable rules (generally, to the oldest debt first).

Why It Matters in Research
Payment is one of the most common affirmative defenses in contract and debt litigation, and its treatment in historical sources reflects assumptions about commercial practice that researchers must handle carefully.
In Rapalje & Lawrence and comparable 19th-century dictionaries, payment doctrine is largely common-law based and creditor-protective: the rules on application of payments, payment to agents, and the effect of a dishonored instrument all developed in an era before negotiable instruments statutes standardized much of this analysis. Researchers working with pre-UCC materials should be alert to the fact that payment by check was not universally treated as conditional payment — the rule that a check constitutes only conditional payment until honored is a modern commercial law position that older sources treat inconsistently.
The distinction between payment and tender is frequently collapsed in older pleading manuals. A plea of "payment" in equity proceedings sometimes encompassed what would now be called tender plus acceptance, and it is worth reading the specific procedural context before concluding that a historical source confirms actual discharge.
In tax contexts, payment carries specialized meanings that diverge from the general contract-law framework. Estimated tax payments, withholding, and credits operate under statutory regimes that define when a payment is "made" for purposes of penalty computation — rules that do not track common-law payment doctrine at all. Researchers moving between general contract sources and tax materials should treat the tax definition of payment as essentially a separate term.
Application-of-payments rules — which debt gets credited when a debtor makes a partial payment — generated substantial 19th-century equity litigation, particularly in mortgage contexts. Law Mind's historical corpus contains considerable material on this, and researchers should expect to find it under both "payment" and "appropriation of payments" in index systems of that era.

Historical Dictionary Support
Rapalje & Lawrence define payment as "the fulfillment of a promise, or the performance of an agreement," emphasizing that while money is the standard medium, anything accepted by the creditor in satisfaction of a money demand may constitute payment. This reflects the 19th-century common-law position that payment is ultimately a consensual act — the creditor's acceptance is what gives it operative legal effect.
Rapalje & Lawrence also note the distinction between payment and accord and satisfaction, though the treatment is compressed. Their entry is more useful for identifying the basic elements than for resolving edge cases; researchers should supplement it with treatise authority for the application-of-payments rules, which they do not systematically cover.
What historical dictionaries generally miss is the procedural significance of payment as a plea. By the 19th century, payment was a recognized affirmative defense requiring specific pleading in many jurisdictions, and the burden of proof sat firmly on the defendant. Sources that define payment substantively often fail to address these procedural mechanics, which matter as much as the substantive definition when working with historical litigation records.

Jurisdictional Note
The common-law framework for payment is broadly uniform across American jurisdictions, but the effect of payment by negotiable instrument (check, note) varies under each state's enactment of the Uniform Commercial Code. In tax matters, federal payment rules under the Internal Revenue Code govern entirely independently of state contract law.
