While a prenuptial or postnuptial agreement can certainly be changed or revoked entirely, both parties must agree. In fact, there are many different reasons a couple might want to change their prenuptial agreement, including: The couple has children and seeks to account for the children in their prenuptial agreement There is an agreement between the spouses for a redistribution of property allocation Additional property is acquired by one spouse and both spouses want to include this property in the original agreement (otherwise, any property acquired during the marriage falls under equitable distribution rules of NC, meaning it will be divided fairly)
