A prenuptial agreement is a written agreement between two people who are going to get married. Most prenuptial agreements concern what will happen to a couple's money, property, or children if the marriage ends. It is used only if a problem occurs in the marriage and the couple decides to get divorced. However, some prenuptial agreements also describe how the husband and wife must act during the marriage. Steve and Karen Parsons made this type of agreement. They wrote a contract with rules for how they must behave in almost every part of their daily lives after they tie the knot.
