Definition
A liquidated account is a claim for money in which the amount owed is certain, fixed, and not subject to dispute or further calculation. The sum is determined either by the express agreement of the parties, by the terms of a written instrument, or by operation of law — leaving nothing to be resolved through proof, estimation, or judicial discretion. The debt is, in effect, already computed: it is so much, or it is nothing.
The concept stands in contrast to an unliquidated account, where the amount remains open, contested, or dependent on facts still to be established. A promissory note for a stated sum, a price term in a completed sale, or a settled balance on a running account are typical examples of liquidated accounts. A claim for damages whose value has not yet been determined is not.
The term operates at the intersection of pleading, procedure, and remedies. In practice, it governs whether a creditor may obtain judgment by default or summary process without a full trial on the merits of the amount owed.

Common Language
Modern common usage (Wiktionary): "Liquidated" in ordinary English derives from financial usage meaning converted into cash or settled — as in liquidating assets or liquidating a business.
Historical common usage (Webster's 1913): To liquidate meant "to ascertain the amount of, and settle" a debt or obligation; also to wind up the affairs of a concern by converting assets to cash.
The gap between common and legal meaning is narrow but important. In everyday financial language, "liquidated" suggests a process of settlement or conversion. In legal usage, a liquidated account does not require that payment has actually been made — only that the amount is already ascertained and fixed. An unpaid debt of a definite sum is legally liquidated even if no cash has changed hands.

Common Confusion
LIQUIDATED ACCOUNT vs. LIQUIDATED DAMAGES: These are related but distinct concepts. A liquidated account is a pre-existing debt or obligation whose amount is already certain. Liquidated damages refers to a contractually specified remedy agreed upon in advance for breach, which may or may not reflect actual loss. Not every liquidated damages clause creates a liquidated account; the clause must survive challenge as a reasonable pre-estimate of harm rather than a penalty before the amount becomes fixed and enforceable.
LIQUIDATED ACCOUNT vs. ACCOUNT STATED: An account stated arises when parties examine a running account, agree on the balance, and the debtor acknowledges it — creating a new, enforceable obligation. A liquidated account may exist without any such mutual review or acknowledgment; the amount need only be fixed by the original terms or by law. An account stated is one common path to liquidation, but the two concepts are not synonymous.

Why It Matters in Research
The distinction between liquidated and unliquidated claims is procedurally consequential and surfaces across multiple bodies of law. Researchers should be alert to the following:
Pleading and default judgment. Courts historically allowed entry of judgment by default on a liquidated account without a formal hearing on damages, since no factual inquiry into the amount was needed. This procedural shortcut does not apply to unliquidated claims. Historical pleading manuals and forms books treat the distinction as foundational.
Pre-judgment interest. Whether pre-judgment interest accrues — and from what date — often depends on whether the claim was liquidated. Some jurisdictions allow interest only on liquidated sums from the date the debt became due, not on unliquidated demands. This creates research traps when reading older cases applying interest rules, since the underlying question of liquidation may be assumed rather than analyzed.
Set-off and counterclaims. Procedural rules in equity and at common law treated liquidated and unliquidated demands differently for purposes of set-off. A defendant could typically set off a liquidated cross-claim against a plaintiff's liquidated demand more readily than an unliquidated one. Historical equity practice and early code pleading cases reflect this distinction.
Bankruptcy and insolvency. Proofs of claim in insolvency proceedings turn on whether the amount can be fixed. Liquidated accounts are admitted to proof directly; contingent or unliquidated claims require estimation. Researchers working with nineteenth- and early twentieth-century insolvency materials will encounter this distinction frequently.
Corpus connections. The liquidated/unliquidated distinction appears across contracts, civil procedure, commercial law, and creditor-debtor materials. It is not siloed to any single field.

Historical Dictionary Support
Both Black's and Bouvier's define a liquidated account by the same functional standard: the amount is certain and fixed, either by agreement of the parties or by operation of law. The sources converge on this core, and neither introduces material qualification.
Black's adds a useful gloss — "a sum which cannot be changed by the proof" — that captures the procedural significance of the concept more sharply than a purely transactional description would. It also notes explicitly that the term does not necessarily refer to a writing, which is an important clarification: liquidation is a legal status, not a documentary one. A verbal agreement fixing a price, or a statutory rule setting a rate, can liquidate an account just as effectively as a signed instrument.
Bouvier's formulation is more compact but consistent, and its string of case citations (Connecticut and Georgia authorities from the mid-to-late nineteenth century) reflects that the concept was well-settled and widely applied at common law well before the modern era.
Neither source devotes attention to the procedural consequences of the distinction — default judgment availability, interest accrual, set-off — which are often the operative reason the characterization matters in litigation. Researchers should not treat the dictionary definitions alone as a complete picture.

Jurisdictional Note
The substantive definition of a liquidated account is broadly uniform across American jurisdictions. Procedural consequences — particularly default judgment rules and pre-judgment interest entitlement — vary by state and should be checked against local rules and statutes. Some states codify the liquidated/unliquidated distinction in their civil procedure codes; others leave it to common law development.
