What a prenup can and cannot decide, and what makes one hold up years later.
A prenuptial agreement is a contract signed before marriage that decides in advance what happens to property and support if the marriage ends. People tend to assume it is about distrust. In practice it is usually about clarity: a family business, children from an earlier marriage, a large disparity in assets or debts, or an inheritance someone wants to keep separate.
The same document signed after the wedding is a postnuptial agreement, and it raises similar questions.
This is the limit people most often get wrong. A Maryland prenuptial agreement cannot determine child support or child custody. Those questions belong to the child, not to the parents’ contract, and a court decides them on the child’s best interests and the support guidelines whatever the agreement says.
See child support and custody and parenting plans.
Maryland courts will enforce a prenuptial agreement, but they look at how it was made. The elements that matter:
A spouse who later challenges the agreement carries the burden, and has to show something like fraud, duress, coercion, mistake, undue influence, incompetence or unconscionability. That is a real burden, which is why a carefully made agreement usually holds.
Maryland does not require each party to have their own lawyer, but having one materially strengthens the agreement. One attorney cannot represent both people, and an agreement where only one side had advice is the one most likely to be attacked later. If your fiancé’s attorney drafted it, have your own attorney review it before you sign.
Timing matters as much as content. Start months before the wedding, not weeks.
A valid agreement can settle the property and alimony questions that otherwise consume a divorce, which is much of its value. See property and debt division and alimony. It does not by itself end a marriage; the grounds and the process are the same. See grounds for divorce in Maryland.
A related but different document is the marital settlement agreement, which is negotiated when a marriage is ending rather than beginning.
