Legal Definition
A defeasance is a legal concept referring to the failure of a contract or legal obligation to be fully performed, often resulting in a breach of warranty or contract. It signifies that a party has failed to meet a contractual duty, leading to potential remedies for the injured party.
Plain-English Translation
Imagine a situation where someone promised to do something important (like paying money or doing a job), but they didn't actually do it correctly. In law, 'defeasance' means that the promise was broken, and the person who failed to deliver is in trouble because they broke the agreement.
