Definition
Numerata (also rendered numerata pecunia) is a term from Roman and civil law referring to money actually counted out and paid — that is, money physically delivered and received in a transaction, as opposed to money merely promised, acknowledged, or represented in writing. The concept was central to disputes over whether a loan or obligation had genuinely been executed by actual transfer of funds.
In its most precise sense, numerata pecunia denotes the specific act of counting and handing over coins or currency, completing the real element of a mutuum (loan of money) under Roman law. A debtor could challenge a creditor's claim on the ground that the money had never actually been paid over — the exceptio non numeratae pecuniae, or defense of money not counted out.

Common Confusion
Numerata should not be confused with the broader concept of consideration in common law contract doctrine. While both concepts address whether something of value actually changed hands, numerata is specifically concerned with the physical delivery of money in the context of Roman-derived civil law obligations. Common law consideration encompasses a far wider range of acts, promises, and forbearances, and does not require physical transfer. Researchers working in mixed civil/common law jurisdictions or in historical materials should be alert to this distinction.

Core Elements
The operative legal significance of numerata pecunia turned on three conditions:
1. Actual counting and delivery — the money must have been physically transferred from creditor to debtor, not merely acknowledged in a written instrument.
2. Receipt by the debtor — the debtor must have actually received the funds, not merely signed a document reciting that they had.
3. Timing and burden — Roman law placed significant procedural weight on when a debtor raised the non numerata pecunia defense. After a prescribed period (classically two years under later imperial legislation), the presumption shifted and the debtor could no longer easily deny receipt.

Why It Matters in Research
Researchers encountering numerata in historical legal materials — particularly in civil law sources, canon law texts, Scottish law, Louisiana law, or Quebec law — should understand it as a term of art signaling a dispute about whether a monetary obligation was actually consummated by delivery.
The most important navigational point is the companion doctrine: the exceptio non numeratae pecuniae. This defense appears extensively in Justinian's Corpus Juris Civilis (notably at C. 4.30, De non numerata pecunia) and in later civilian commentators. Bouvier's truncated entry references this title directly (L. 8, 10, C. de non numerat. pecun.), pointing researchers to the relevant title in the Codex. Any research into numerata that does not pursue the exceptio is incomplete.
Historical sources from the early American period — including Bouvier's — tend to treat numerata as background Roman law rather than operative American doctrine. Its appearance in domestic materials is therefore a strong signal that the researcher is in a civil law jurisdiction, a Roman law-influenced treatise, or an ecclesiastical/canon law context.
In Louisiana and Quebec materials, the concept retains practical relevance longer than in common law jurisdictions and surfaces in debates over proof of payment and the evidentiary status of written acknowledgments of debt.
Trap for researchers: Written acknowledgments of debt (cautiones, chirographa) in Roman and early civil law do not automatically establish that numerata pecunia occurred. A document reciting that money was received could be challenged as a simulation. This distinction between the written record and the actual transaction is the heart of the non numerata pecunia doctrine and is easy to miss when reading sources that focus on the document rather than the underlying act.

Historical Dictionary Support
Bouvier's Law Dictionary provides only a fragmentary entry, citing the relevant title of Justinian's Codex (C. de non numerat. pecun.) without defining the term itself — the entry in the source material appears to trail off mid-sentence. This is characteristic of how Bouvier treats terms that were standard civilian learning but had limited operative application in American common law courts.
The civilian tradition offers substantially more. The Digest and the Codex of Justinian treat numerata pecunia as the defining feature of the mutuum: a loan of money is not formed by promise or writing alone but requires actual delivery. Later commentators including Pothier (Traité des Obligations) and Domat (Les Lois Civiles) elaborate on this requirement and on the procedural mechanics of the non numerata defense.
What historical dictionaries miss: English-language legal dictionaries uniformly underserve this term because it has no direct common law counterpart. Researchers relying solely on English dictionaries will find little. The substantive treatment is in the Latin civilian sources and in the civilian-tradition treatise literature.

Jurisdictional Note
Numerata pecunia is a term of civil law, not common law, and has no direct operative counterpart in English-derived common law jurisdictions. It retains relevance in Louisiana, Quebec, and other mixed or civilian-tradition jurisdictions, as well as in any research touching Roman law, canon law, or the intellectual history of contract doctrine.
