Use the cancel provision included in the agreement. Most prenuptial agreements include a section that dictates the requirements for canceling the prenuptial agreement, which usually involves the consent of both parties.
Let the "sunset provision" do the work for you. Some prenuptial agreements are drawn up with "sunset" provisions, which cause the prenuptial agreement to automatically expire and no longer be valid after a certain amount of time has passed.
Argue the prenuptial agreement should be ruled invalid because it's not in writing or it wasn't signed before the wedding.
Contend that the prenup should be cancelled because you felt "pressured" or didn't read it before signing it.
Convince a court that either party lied or omitted information during the drafting of the contract.
Get the contract ruled as invalid because an independent attorney didn't represent a party, or if the court finds that the contract is so unfair, it is considered "unconscionable."
