stipulation

This term carries a heavy legal and formal weight, evoking the image of a precise, non-negotiable clause in a contract. It suggests a boundary or a prerequisite that must be met for an agreement to remain valid, often implying a sense of strictness or a specific demand made by one party to protect their interests. While it refers to a requirement, it differs from a general rule by being specific to a particular deal or arrangement. It is almost exclusively used in professional, legal, or diplomatic contexts rather than casual conversation.
