Definition
A nominate contract is a contract that bears a specific, recognized legal name — such as sale, lease, loan, hire, or insurance — with that name carrying defined legal consequences under civil law systems. The name is not merely descriptive; it triggers a particular set of default rules, obligations, and remedies established by law or legal tradition for that category of agreement. A contract without such a recognized name is called an innominate contract.
The concept originates in Roman law, which organized contracts into named categories (nomina contractuum), each governed by its own rules. Within civil law systems that descend from Roman law, whether a contract is nominate determines what gap-filling rules apply when the parties have not addressed a particular term, and sometimes whether the agreement is enforceable at all.
Common Confusion
NOMINATE CONTRACT vs. INNOMINATE CONTRACT: These are paired opposites, and the distinction matters primarily within civil law systems. An innominate contract is one that does not fit a recognized named category and therefore lacks a pre-built body of default rules. Researchers working in common law jurisdictions will encounter these terms mainly in comparative law materials and civil law-influenced jurisdictions (Louisiana, Quebec, Puerto Rico, Scotland, and mixed systems). Do not confuse "nominate" here with "nominal" — the two words are unrelated in legal usage. A nominate contract may involve substantial consideration; a nominal consideration refers to a token amount used to satisfy formal requirements.
Why It Matters in Research
This term is nearly invisible in mainstream American common law materials because the common law does not formally organize contracts into named and unnamed categories in the same way. Researchers encountering "nominate contract" in a U.S. source are almost certainly reading materials from Louisiana, a civil law jurisdiction, or from comparative or international commercial law contexts.
In civilian jurisdictions, whether a contract is nominate has real doctrinal consequences: courts apply the statutory or codified rules for that contract type to fill gaps, interpret ambiguous terms, and assign default obligations. For example, if a Louisiana court characterizes an agreement as a contract of lease rather than a contract of sale, an entirely different set of Civil Code articles governs.
The primary trap for common law researchers is treating "nominate" as a synonym for "named" in the colloquial sense — meaning simply that the parties gave their contract a title. In civilian doctrine, the classification is objective and determined by the nature of the agreement, not by what the parties chose to call it. A contract titled "Service Agreement" might be characterized by a civil law court as a contract of lease of services, nominate under the Civil Code, regardless of the parties' label.
Historical sources will reflect the Roman law taxonomy more explicitly than modern American materials. Researchers using Bouvier's for American contract law should note that his treatment of nominate and innominate contracts draws from civilian tradition and is more directly applicable to mixed or civil law jurisdictions than to most U.S. states.
For comparative and international research, the nominate/innominate distinction surfaces in UNIDROIT materials, civilian treatises, and scholarship on mixed legal systems. It also appears in discussions of unjust enrichment and quasi-contract, where the absence of a nominate contract framework sometimes drives liability analysis differently than in common law.
Historical Dictionary Support
Bouvier's Law Dictionary defines a nominate contract as one "distinguished by a particular name, the use of which name determines the" — the entry as preserved is truncated, but the civilian framework is clear. Bouvier situates the term within Roman law inheritance, where recognized contract names (emptio venditio for sale, locatio conductio for hire, mutuum for loan, and so on) each carried specific actiones and obligations. Wiktionary's current definition — "a contract distinguished by a particular name, such as sale, insurance, or lease" — captures the surface meaning accurately but omits the doctrinal significance: the name does not just identify the agreement, it activates a body of law.
Neither Bouvier nor modern general dictionaries fully convey how the nominate/innominate distinction operates as a gap-filling mechanism in civilian legal reasoning. Researchers relying solely on these definitions may underestimate the term's functional importance in jurisdictions where it applies.
Jurisdictional Note
The nominate/innominate framework is a civilian doctrine with limited direct application in common law states. It operates with full doctrinal force in Louisiana (see Louisiana Civil Code arts. 1914–1916), Quebec, Puerto Rico, and other mixed or civil law systems. In comparative and international commercial law scholarship, the term appears frequently regardless of jurisdiction.
