Like any other contract, the parties in a Premarital Agreement can mutually agree to terminate the agreement. But the terms cannot be nullified by just one of the parties to the contract without valid legal grounds.
But valid legal grounds do exist that would nullify the agreement: fraud, coercion, a factual mistake, etc. These grounds are set forth in case law (i.e. a court\’s decisions) and have specific elements to each that require detailed review.
