n. particularly in contracts, what a prudent person would believe and act upon if told something by another.

The one who relied can recover damages for the costs of his/her actions or demand performance if the reliance was "reasonable." If the promisor says he "owned the Brooklyn Bridge," reliance on that statement is not reasonable. In a complaint the language would read something like: "in reasonable reliance on defendant's statement (or promise), plaintiff did the following…."
