Can prenuptial agreements expire? Is there a statute of limitations?

Yes.  Parties can have their attorneys prepare a prenuptial agreement that is not permanent in nature but instead one that expires after a certain number of years.  They may insert a sunset provision into the premarital contract, stating that after a specific period of time, such as five years, the contract will expire.  Some states, such as Maine, provide for the automatic expiration or lapsing of a prenuptial agreement after the couple gives birth to a child, unless they renew the contract. 

In other states, the agreement will lapse after the couple has been married for a certain number of years.  Still, other states, where the Uniform Prenuptial Agreement Act (UPAA) is in effect, allow parties to contract for a sunset provision.  You and your partner are free to choose the length of time that you wish your premarital agreement to be in force as well as which portions of the contract will expire.  Parties can decide that their agreement will expire either partially or in its entirety; however, they must do so explicitly.
