Legal Definition
In a legal context, 'expire' refers to the termination of a legal right, validity period, or contractual term, signifying the end of a defined duration or obligation. It is crucial for determining when a legal action ceases to be valid or when a contractual obligation ends.
Plain-English Translation
Imagine a rule that says something is no good after a certain time runs out. 'Expire' means that time has run out, and the rule or contract is now finished. For instance, if a ticket to a game expires, it means the time limit for using that ticket has ended.
