The District of Columbia governs premarital agreements under the Uniform Premarital Agreement Act, codified at D.C. Code §§ 46-501 through 46-510. The statute permits parties to contract regarding property rights, spousal support, and certain estate matters, but it draws hard lines around the rights of children. Understanding where that line sits — and where it doesn’t — is the difference between an agreement a court will enforce and one it will strike down as unenforceable.

Alimony:

The Most Negotiated Clause, and the Most Enforceable provision. Sec. 46-503(a)(4) expressly authorizes parties to modify or eliminate spousal or domestic partner support. A full waiver, a fixed dollar cap, a durational limit, or a lump-sum buyout are all permissible. The District of Columbia Court of Appeals upheld a modest lump-sum limitation in Burtoff v. Burtoff, 390 A.2d 989 (DC 1980), and has consistently treated support waivers as ordinary contract terms rather than public-policy violations. The single statutory override appears in § 46-506(b): if enforcing the waiver would leave a spouse eligible for public assistance at separation or dissolution, the court may order support only to the extent necessary to avoid that eligibility. That is a floor, not a license to rewrite the agreement. Critically, unconscionability is measured as of the date of execution — § 46-506(c) makes it a question of law for the judge — so a waiver that looks harsh at divorce remains enforceable if it was reasonable when signed.

Child Support: Off-Limits

Section 46-503(b) provides that a premarital agreement may not adversely affect the right of a child to support. Any clause purporting to waive, cap, or predetermine child support is void. Child support belongs to the child, not the parents, and the Superior Court applies the guideline in § 16-916.01 based on the parents’ incomes and the custody arrangement at the time of the proceeding. A below-guideline provision in a prenup will not bind the court, and attempting to include one invites scrutiny of the entire agreement.

Child Custody: Judicially determined and not contractual overridden

Custody determinations rest exclusively with the court under the best-interests standard of § 16-914. In Spires v. Spires, the Court of Appeals invalidated portions of a marital agreement that preemptively allocated custody, holding that parents cannot by contract deprive the court of its power to determine what serves the children. A prenup clause granting or denying custody is not binding; the judge will set it aside and conduct a fresh analysis. The same principle applies to visitation and parenting-time schedules.

Property Division: Broadly Enforceable

Section 46-503(a)(3) permits parties to define the disposition of property upon separation, dissolution, annulment, or death. This is the workhorse of most DC prenups. In Critchell v. Critchell, 746 A.2d 282 (D.C. 2000), the Court of Appeals enforced a waiver of rights to the other spouse’s retirement accounts, rejecting the trial court’s equal division and confirming that a properly drafted agreement can shield pension and retirement assets from marital claims. Property clauses covering premarital assets, future earnings, business interests, and appreciation are routinely upheld.

Estate and Insurance Provisions

Parties may also address wills, trusts, and life-insurance death benefits. A clause designating who receives a policy’s proceeds or requiring maintenance of coverage is enforceable, subject to the same voluntariness and disclosure requirements that govern the rest of the agreement.

The Enforcement Gatekeepers

Two grounds defeat enforcement under § 46-506(a). First, involuntary execution — coercion, threats to cancel the wedding, presentation on the eve of the ceremony, or denial of meaningful opportunity to consult counsel. Second, unconscionability at signing combined with all three disclosure failures: no fair and reasonable disclosure of the other party’s property and financial obligations, no voluntary written waiver of further disclosure, and no adequate independent knowledge. Any one of the three disclosure conditions being satisfied defeats the challenge. Disclosure schedules should itemize assets, debts, income sources, contingent liabilities, and business interests with precision; an understated schedule is the most common litigation vulnerability.

Litigation experience directly correlates with drafting an enforceable prenuptial agreement. The small textual ambiguities, disclosure gaps, and procedural shortcuts that opposing counsel seize upon in a contested enforcement action are precisely the details litigants must anticipate and close before the ink dries. A clause that reads cleanly in a conference room can collapse under cross-examination when the record lacks a signed disclosure waiver, a dated financial schedule, or evidence of independent counsel. The attorney who has watched agreements fail in court knows that enforceability is not a matter of elegant language but of an unbroken evidentiary chain — voluntariness documented, disclosure itemized, unconscionability foreclosed as a matter of law. Drafting without litigation experience, perspective and produces will render an agreements that look complete on paper fragile and unenforceable in practice.
