Definition
Satisfaction is the discharge of an obligation by fulfilling what is legally owed or what has been agreed upon as an acceptable substitute. The term carries distinct meanings depending on the legal context in which it appears.
1. Contract law. The performance of a contractual duty in the manner required, or the acceptance of something in lieu of that performance, such that the underlying obligation is extinguished. Satisfaction in this sense often pairs with accord: the accord is the agreement to accept a substitute; satisfaction is the actual delivery of that substitute. Until satisfaction occurs, the original obligation is not discharged.
2. Judgment satisfaction. The payment — or other legally recognized discharge — of a monetary judgment recovered in a court proceeding. Satisfaction of a judgment extinguishes the creditor's right to enforce it. In practice, satisfaction is memorialized by an entry on the court record (a satisfaction piece or satisfaction of judgment), releasing the judgment debtor from further liability under that judgment.
3. Mortgage and lien satisfaction. The discharge of a mortgage, lien, or security interest upon full payment of the secured debt. A satisfaction of mortgage is the formal instrument evidencing that the encumbrance has been released. Recording requirements for such instruments vary by jurisdiction.
4. Equity: satisfaction of portions and legacies. In equitable doctrine, satisfaction addresses the overlap between two independent gifts or obligations — for example, where a portion promised to a child in a settlement is later duplicated by a legacy in a will. Equity may treat the legacy as satisfying the earlier obligation, preventing a double benefit. This doctrine is closely associated with ademption (the extinction of a legacy by a lifetime gift) but is conceptually distinct from it.
5. Satisfaction clauses in contracts. Some contracts make performance expressly contingent on one party's satisfaction — "to the satisfaction of the owner," for instance. Courts analyze whether such clauses invoke a subjective standard (the actual satisfaction of that party, exercised in good faith) or an objective standard (the satisfaction of a reasonable person). The distinction determines when performance is legally complete.

Common Language
Modern common usage (Wiktionary): A fulfillment of a need or desire; the pleasure obtained by such fulfillment; a reparation for an injury or loss.
Historical common usage (Webster's 1913): The act of satisfying; gratification of desire; contentment in possession and enjoyment; settlement of a claim, due, or demand; payment; adequate compensation.
The ordinary meaning of satisfaction centers on subjective contentment — a state of mind. The legal meaning is more precise and less psychological: it denotes the objective discharge of a legal obligation by performance, payment, or an accepted equivalent. A debtor who pays a judgment debt has given satisfaction in the legal sense regardless of whether the creditor feels gratified. The gap matters most in contracts containing satisfaction clauses, where courts must decide whether the parties incorporated the common-language sense (genuine personal contentment) or the legal sense (objectively adequate performance).

Common Confusion
Satisfaction is frequently conflated with two related but distinct concepts.
Accord and satisfaction vs. satisfaction alone. An accord is the agreement to accept something different from what was originally owed; satisfaction is the performance of that agreement. Satisfaction alone, without accord, refers to the discharge of the original obligation on its own terms. The two operate in sequence: no discharge occurs until both are present.
Satisfaction vs. ademption (equitable doctrine). In the equity context involving portions and legacies, satisfaction and ademption are related but not interchangeable. Ademption operates when a testator makes a lifetime gift that is treated as replacing a bequest — the bequest is adeemed (revoked). Satisfaction, in the equitable sense, operates when a prior obligation (such as a promised portion) is treated as discharged by a later gift. Historical sources, including Rapalje & Lawrence, draw this distinction explicitly; older cases occasionally use the terms loosely.

Recognized Forms
/SUBTYPES
Accord and satisfaction. Discharge of a contract or claim by mutual agreement to accept a substitute performance, followed by delivery of that substitute.
Satisfaction of judgment. The formal extinguishment of a court judgment upon payment or other discharge, typically recorded in the court docket.
Satisfaction of mortgage. The release of a mortgage lien upon full payment of the secured obligation, evidenced by a recorded instrument.
Equitable satisfaction. The doctrine by which a prior obligation (particularly a portion or legacy) is treated as discharged by a subsequent gift or bequest from the same obligor or testator.
Satisfaction clause performance. Completion of a contractual obligation contingent on one party's expressed satisfaction, governed by either a subjective or objective standard depending on the nature of the contract.

Why It Matters in Research
Researchers encounter satisfaction across multiple distinct bodies of law — contract, judgment enforcement, real property, and equity — and the doctrinal rules differ in each. Conflating these contexts is a persistent trap in historical sources, which often define the term in a single sentence and move on.
For contract researchers: the accord and satisfaction doctrine has a long common law history, but its application to disputed debt settlements shifted significantly in the twentieth century with the adoption of the Uniform Commercial Code. UCC Article 1 modified common law accord and satisfaction rules for negotiable instruments and commercial paper. Pre-UCC sources may not reflect current doctrine.
For judgment researchers: satisfaction of judgment entries were historically a matter of court record practice, not always a separately filed instrument. The procedural mechanics — who makes the entry, when it is required, what happens if a satisfied judgment is not formally marked — vary by jurisdiction and era. Colonial and early American court records may reflect satisfaction by informal notation rather than a separate document.
For real property researchers: satisfaction of mortgage is a recording act matter. The obligation to record a satisfaction, the form of the instrument, and the consequences of a creditor's failure to record vary meaningfully across states and across time. Pre-twentieth century sources often describe practice in states that have since overhauled their recording systems.
For equity researchers: the equitable doctrine of satisfaction of portions and legacies is largely a product of English chancery practice. American courts received it unevenly, and many modern courts have abandoned or substantially limited it. Historical equity treatises — including the sources cited by Rapalje & Lawrence (Haynes, Snell, White & Tudor) — describe English practice that may not reflect American application.
Satisfaction clauses are a distinct research problem. The subjective/objective distinction in satisfaction clauses developed through case law across the late nineteenth and twentieth centuries and is now addressed directly in encyclopedia entries on contract interpretation. Historical dictionaries do not address this doctrinal line at all.

Historical Dictionary Support
Black's Law Dictionary (both editions) defines satisfaction primarily through the judgment and debt-payment context: paying what is due under a mortgage, lien, contract, or judgment, and the formal record entry that evidences that payment. The first edition's treatment is truncated in the surviving excerpt but consistent with the second edition's more complete account. Both editions treat satisfaction of judgment as the paradigm case.
Burrill's Law Dictionary offers the most precisely structured definition among the historical sources, grounding satisfaction in its Latin root (satisfactio) and distinguishing its use in practice (payment of a legal debt or demand, typically one of record) from its broader equitable applications. Burrill is useful for locating the term's procedural orientation in nineteenth-century practice.
Rapalje & Lawrence provides the most doctrinally useful account of equitable satisfaction, identifying it as the exhaustion of an obligation by performance or an act equivalent to performance, and explicitly distinguishing satisfaction from ademption. The citation to Haynes's Principles of Equity, Snell's Principles of Equity, and White & Tudor's Leading Cases in Equity points researchers toward the English chancery sources underlying American equity practice on this point.
Bouvier's Law Dictionary entries as excerpted here are fragmentary and do not independently add to the synthesis, though Bouvier's fuller treatment elsewhere addresses presumptions of satisfaction in debt contexts.
None of the historical dictionaries addresses satisfaction clauses in contracts as a distinct interpretive problem — that doctrinal development postdates the primary edition periods of these sources. Researchers relying solely on historical dictionaries for satisfaction clause analysis will find no guidance on the subjective/objective standard distinction.

Jurisdictional Note
Mortgage satisfaction recording requirements differ substantially by state: some jurisdictions impose mandatory recording obligations on lenders within a fixed period after payoff, with statutory penalties for non-compliance; others leave recording to the parties. Accord and satisfaction doctrine in commercial transactions is governed in most U.S. jurisdictions by Article 1 of the UCC, which preempts older common law rules in that context. The equitable doctrine of satisfaction of legacies has been largely displaced in American jurisdictions by testamentary and probate statutes.
