What term refers to an event that can nullify a right in a contract?

The correct term that refers to an event that can nullify a right in a contract is "condition subsequent." A condition subsequent is a specific event or circumstance that, if it occurs, can terminate or nullify the obligations or rights defined in the contract. For example, if a contract includes a clause stating that a party’s obligation to perform certain duties is contingent upon the occurrence of a specific event (such as the failure to meet certain conditions), and that event occurs, the rights outlined in the contract can be rendered void.

Understanding this term is important for anyone involved in contractual agreements, as it outlines the potential for certain conditions to impact the enforceability of the contract. Condition precedent, on the other hand, refers to an event that must occur before a party's obligation arises, not one that nullifies it. Breach represents a violation of contract terms but does not specifically refer to a condition that nullifies rights, while misrepresentation involves providing false information that may lead to an unenforceable contract but does not directly relate to nullifying a right through conditions.
