Prenuptial Agreement (Financial)

From a financial planning perspective, a prenuptial agreement is fundamentally a risk management tool. It allows each party to enter marriage with clear expectations about the treatment of premarital assets, anticipated inheritances, business ownership, and financial obligations — reducing the potential for litigation and wealth destruction if the relationship ends.

Common uses include protecting a business or professional practice from becoming a marital asset subject to division, preserving premarital investment portfolios or real estate, defining spousal support terms, protecting children from a prior relationship, and addressing debt responsibility. In states with community property laws, a prenuptial agreement can specify that certain assets earned during the marriage will be treated as separate rather than community property.

For a prenuptial agreement to be enforceable, courts generally require full financial disclosure by both parties, independent legal representation or a clear waiver of the right to counsel, that the agreement was signed voluntarily and without coercion, and that its terms are not unconscionable at the time of enforcement. An agreement signed the night before the wedding, without both parties having reviewed it with their own attorneys, is vulnerable to challenge.

Postnuptial agreements serve a similar function but are executed after marriage. They can be used when circumstances change significantly — a large inheritance, the founding of a business, or a blended family situation that was not anticipated when the marriage began.

Prenuptial agreements do not cover child custody or child support, as courts in every US state retain jurisdiction over decisions affecting the welfare of children regardless of any private agreement between the parents.
