For couples in Bethesda, Potomac, Chevy Chase, Georgetown, and throughout the greater Washington, D.C. area, marriage often brings together not just two individuals, but two sets of family wealth — inherited trusts, closely held businesses, real estate portfolios, and generational assets that took decades to build. A well-drafted prenuptial or postnuptial agreement is one of the most effective tools available to protect that wealth, clarify expectations, and avoid costly, uncertain litigation if the marriage later ends.
Yet many high-net-worth individuals delay this conversation, assuming it is either unnecessary, unromantic, or legally complicated. In reality, Maryland law gives couples significant flexibility to define their own financial arrangement — but only if the agreement is properly drafted and executed.
Why Maryland Law Makes These Agreements Especially Important
Maryland is an equitable distribution state. Under the Maryland Code, Family Law Article, § 8-201, property acquired before the marriage, or acquired during the marriage by inheritance or gift from a third party, is generally treated as non-marital property and is not subject to division in a divorce — unless it has been commingled with marital assets or its separate character cannot otherwise be traced.
That protection sounds reassuring, but in practice it is fragile. Inherited funds deposited into a joint account, a family business that a spouse actively works in and grows during the marriage, or the appreciation on a premarital investment portfolio can all become entangled with marital property over the course of a long marriage. Once assets are commingled, tracing them back to their separate, non-marital origin can become a difficult and expensive forensic accounting exercise — and sometimes an impossible one. A prenuptial or postnuptial agreement allows a couple to define, in advance, exactly what stays separate and how it will be treated, removing that uncertainty entirely.
Prenuptial Agreements Under Maryland Law
Maryland does not have a comprehensive statute specifically governing premarital agreements. Instead, under § 8-101 of the Family Law Article, spouses (and prospective spouses) may enter into a valid and enforceable agreement relating to alimony, support, and property rights. Maryland courts evaluate these agreements under general contract law principles, with particular attention paid to the fact that the parties are in a confidential relationship at the time of signing.
Because of that confidential relationship, Maryland courts apply heightened scrutiny to prenuptial agreements when they are challenged, examining the agreement for what courts describe as "overreaching" — a concept with both a procedural component (was the agreement entered into fairly) and a substantive component (is the resulting agreement itself unfair). Generally, an enforceable Maryland prenuptial agreement should include:
- A written agreement, signed by both parties, before the marriage takes place
- Full and honest financial disclosure from both spouses regarding assets, debts, and income
- Voluntary execution, free from duress, coercion, or undue pressure
- Independent legal counsel for each party, or at minimum, a clear and documented opportunity to consult with separate counsel
- Adequate time to review the agreement before the wedding, rather than presenting it for signature at the last minute
Maryland courts can invalidate or refuse to enforce a prenuptial agreement found to be the product of fraud, mistake, incompetence, undue influence, or unconscionability. This is precisely why cutting corners on disclosure or timeline is one of the most common — and most avoidable — mistakes wealthy couples make when drafting these agreements.
Postnuptial Agreements: A Tool for Couples Already Married
Not every couple has the opportunity, or the foresight, to sign an agreement before the wedding. Fortunately, Maryland law also permits married couples to enter into postnuptial agreements — contracts signed after marriage that address the same categories of issues: how property will be classified, divided, or protected in the event of divorce or death.
Postnuptial agreements are particularly useful for couples who:
- Received a significant inheritance or family gift after marrying
- Started or grew a business together, or where one spouse built a business during the marriage
- Established or restructured family trusts after the wedding
- Simply never got around to a prenuptial agreement but want the same clarity and protection now
Maryland courts apply similar fairness and disclosure principles to postnuptial agreements as they do to prenuptial agreements, generally requiring that the agreement not be the product of overreaching and that both spouses had full knowledge of the marital finances before signing. Because spouses are already bound to each other by marriage at the time of signing — and because postnuptial agreements can sometimes be scrutinized even more closely by courts than prenuptial agreements — careful drafting, full transparency, and independent counsel for each spouse are especially important.
Coordinating Marital Agreements With Trusts and Estate Planning
For high-net-worth families, a prenuptial or postnuptial agreement rarely exists in isolation. It typically needs to work in tandem with a broader estate plan, including:
- Family and dynasty trusts. An agreement should clarify that trust assets, and any distributions from an irrevocable trust, remain the separate property of the beneficiary spouse and are not converted into marital property through use during the marriage.
- Inheritance expectations. Couples with anticipated inheritances from parents or grandparents can address, in advance, how those future assets will be treated if received during the marriage.
- Business succession plans. For family businesses intended to pass to the next generation, a marital agreement can help ensure that a divorce does not force a sale, dilution, or unwanted co-ownership of the company.
- Life insurance and beneficiary designations. Coordinating these designations with the marital agreement avoids conflicting instructions between the contract and other estate planning documents.
Because these instruments intersect, it is important that a family law attorney draft the marital agreement in coordination with the couple's estate planning attorney and, where relevant, the family office or wealth manager overseeing trust administration.
What a Prenuptial or Postnuptial Agreement Cannot Do
Maryland law places clear limits on what these agreements may address. A marital agreement cannot determine child custody or child support in advance — those issues remain subject to the court's independent judgment, based on the best interests of the child, regardless of what the agreement says. Agreements also cannot include terms that violate public policy or law, and courts will not enforce provisions that effectively encourage or reward divorce. Understanding these boundaries up front helps avoid drafting provisions that could later be challenged or struck from the agreement.
Protecting Wealth Without Undermining Trust
For many high-net-worth couples, the hesitation around a prenuptial or postnuptial agreement is less about the law and more about the conversation itself. An experienced family law attorney can help frame these agreements as what they are: a practical, forward-looking financial planning tool — not a sign of distrust. When approached early, with full transparency and the guidance of experienced counsel on both sides, these agreements typically strengthen a marriage's financial foundation rather than undermine it.
