Nudum Pactum Law and Legal Definition

Nudum Pactum is a Latin word which means “bare agreement.” It is an agreement that is unenforceable as a contract because it is not “clothed” with consideration required by law. This is also referred to as naked contract or nude contract or nude pact

In Roman law, it refers to an informal agreement that is not legally enforceable, because it does not fall within the specific classes of agreements that can support a legal action. However a pactum could create an exception to or modification of an existing obligation.
