nudum pactum
Very LowFormal, Technical (Law)
Definition
Meaning
An agreement or promise that is not legally enforceable due to the absence of consideration (something of value exchanged).
In common law, a 'naked' or 'bare' agreement that lacks the essential element of consideration (something given in return for a promise), rendering it unenforceable in court.

Learning
Memory Aids
Mnemonic
Think of 'nudum' as 'nude' or naked, and 'pactum' as pact or promise. A 'naked promise' lacks the 'clothing' (consideration) needed to be legally valid.
Conceptual Metaphor
A PROMISE IS AN OBJECT; a legally valid promise/contract is a DRESSED OBJECT; a nudum pactum is a NAKED/UNDRESSED OBJECT (lacking the essential covering of consideration).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'голый пакт'. It is a specific legal term: 'неподкрепленное встречным предоставлением соглашение' or 'неформальный договор' (in the legal sense).
- The concept of 'consideration' (встречное удовлетворение) is key and has no direct, simple equivalent in Russian civil law systems.
- Confusing it with a simple 'oral agreement' (устное соглашение), which may be binding in some contexts.
Common Mistakes
- Using it to describe any informal agreement. It specifically refers to lack of *consideration*, not lack of writing.
- Pronouncing 'pactum' with a hard /k/ like 'pack-tum'; the 'c' is soft /k/ before 't'.
- Thinking it applies to all non-contractual promises; some promises are binding without consideration (e.g., under seal).
