/n(j)uːdʌm pæk.tʊm/ – Phrase
Definition: Thỏa thuận không có giá trị pháp lý.
A more thorough explanation: a Latin phrase that means a bare promise. In common law jurisdictions, the phrase refers to a promise that is not legally enforceable because there is no consideration (=payment) agreed at the time the promise was made.
Example: A unilateral undertaking is nudum pactum, and therefore not binding in those jurisdictions which require consideration.
