As noted, it depends. A couple may not own many assets when they first get married. Therefore, it may not make sense at the time to enter into a prenuptial agreement. However, if the parties accumulate assets over time during the marriage, if one spouse starts a new business, or if one person comes into a large inheritance during the marriage, it may start to make a lot of financial sense to enter into a postnuptial agreement. Moreover, finances are one of the leading causes of stress and conflict in marriages. Couples sometimes discover only after they’re married that they have vastly different spending habits and/or attitudes about money. Agreeing to a postnuptial agreement may reduce simmering tension in a marriage over finances.
