Legal Definition
Invalidity refers to a legal concept where a contract, claim, or action is deemed void because it lacks a fundamental defect that prevents its valid execution or recognition under the law. In legal contexts, this often relates to the failure of a legal action to meet the required standards for validity.
Plain-English Translation
Imagine something is 'invalid' when it breaks the rules of the game. For example, if a contract says something is invalid, it means the rulebook shows that the agreement or claim doesn't actually work because it misses a crucial requirement needed to be legally valid.
