DC Prenuptial Agreement
District of Columbia prenuptial agreements are governed by the D.C. Uniform Premarital Agreement Act, D.C. Code §§ 46-501 to 46-510. Courts apply single review only — unconscionability is assessed at signing, not additionally at divorce — and challengers must prove either involuntary execution OR all three of: unconscionability at signing, inadequate disclosure, and lack of financial knowledge. Unconscionability alone is not enough. Spousal support waivers are enforceable with a minimum of public assistance eligibility.
Bottom line: D.C. earns an A grade. Single review, a tough challenge standard, and a clear alimony floor at public assistance eligibility give D.C. prenups more certainty than most other states.
District of Columbia Prenup Enforceability Rating: A
District Of Columbia Prenup Laws: Key Statutes Explained
1996 D.C. Uniform Premarital Agreement Act, D.C. Code §§ 46-501 to 46-510
Alimony must be at least public assistance in prenups, single review only.
Separate Property
All assets can remain separate property, avoiding costly divorce settlements. Joint assets and debts titled in both names can be split 50/50 according to a prenuptial agreement.
Unconscionability Single Review (Pro-Prenup)
D.C. reviews prenuptial agreements for unconscionability ONLY at execution (signing), not at enforcement (divorce). This prevents courts from second-guessing agreements based on changed circumstances during marriage, providing greater certainty and discouraging litigation challenges.
Unconscionability Standard—§ 46-506 Two-Prong Test
A prenup is unenforceable if the challenging party proves: (1) involuntary execution due to coercion or undue pressure; OR (2) the agreement was unconscionable at execution AND (a) lacked fair and reasonable disclosure of the other's property/obligations, (b) no written waiver of disclosure, AND (c) challenging party lacked adequate knowledge of the other's finances. Per Simon v. Smith, 273 A.3d 321 (D.C. 2022), unconscionability requires both procedural and substantive unfairness.
Spousal Support Public Assistance Minimum
Courts may override spousal support waivers if enforcement would make one party eligible for public assistance at separation or divorce. However, courts can only require support "to the extent necessary to avoid that eligibility" under § 46-506(b).
Timing
No minimum specified, but we recommend signing the prenup 30+ days before the wedding, with both parties having 2-3 weeks to review the final version to minimize challenge risk. Norris v. Norris, 419 A.2d 982 (D.C. 1980), invalidated an agreement signed roughly an hour before the wedding. Reach out to an attorney at least 4-6 months before the wedding with your draft prenup. Better yet, sign the prenup before proposing.
Independent Counsel
Not required, but separate counsel dramatically strengthens enforceability if the agreement is later challenged. D.C. courts closely scrutinize whether parties had opportunity for independent legal review.
Financial Disclosure
"Fair and reasonable disclosure" of property and financial obligations required under § 46-506, or written waiver. PerfectPrenup includes both.
Moderate Burden to Challenge
Challenging party must prove either involuntary execution or unconscionability plus lack of disclosure by preponderance of evidence. D.C. courts favor enforcement of prenuptial agreements but apply heightened scrutiny under Burtoff v. Burtoff, 418 A.2d 1085 (D.C. 1980).
Child Support and Custody
Child support and custody clauses are unenforceable and could undermine the entire agreement. Do not include.
District Of Columbia Prenuptial Agreement Court Cases
Simon v. Smith, 273 A.3d 321 (D.C. 2022)
The D.C. Court of Appeals struck down two 2010 spousal agreements — a below-market lease with a fixed $290K purchase option and a property-management agreement giving the husband's trust irrevocable control over the wife's pre-marital condo — as both procedurally and substantively unconscionable, articulating the controlling two-prong unconscionability test.
Norris v. Norris, 419 A.2d 982 (D.C. 1980)
Applying Florida law per a choice-of-law clause, the court invalidated an antenuptial agreement signed roughly one hour before the wedding because the husband (net worth ~$450K) failed to fully disclose his assets and the circumstances were unduly coercive to the wife.
Macklin v. Johnson, 268 A.3d 1273 (D.C. 2022)
Though not a prenup case, the court held as a matter of first impression that a homemaker spouse's substantial non-financial contributions can support an equitable interest in the other spouse's separately-titled real property — awarding the wife 40% ($203,984) of the cash-out value of the husband's pre-marital home — making express reciprocal waivers of homemaker-based equitable claims essential in any D.C. prenup.
Burtoff v. Burtoff, 418 A.2d 1085 (D.C. 1980)
The court enforced an antenuptial agreement providing the wife a tiered lump sum ($10K if marriage <1 year, up to $50K on death) against a husband worth ~$1M, holding such contracts are not void on public policy grounds and establishing D.C.'s heightened-scrutiny test for fairness, voluntariness, and adequate financial disclosure.
Critchell v. Critchell, 746 A.2d 282 (D.C. 2000)
The court held that ERISA does not preempt a validly executed premarital waiver of a former spouse's marital interest in pension benefits at divorce, distinguishing the divorce-context waiver (enforceable in a prenup) from the ERISA survivor-annuity waiver (which requires a post-marriage spousal consent on the plan form).
5-Step Checklist: How to Sign & Execute a Prenup in District Of Columbia
Step 1: Download and read the District of Columbia prenuptial agreement
Start with our free template. It is written for D.C.-specific statutes and case law under the D.C. Uniform Premarital Agreement Act (D.C. Code §§ 46-501 to 46-510). Read it in full — know what you are getting into legally with marriage. The 15+ pages is written thoroughly to include rebuttals to common legal challenges and fallback provisions.
Step 2: Draft changes on your own
See a clause you don't like? Copy it into an AI like Claude, explain what you'd like to change or what you want the clause "to do." Save any changes as a separate alternate version — don't overwrite the original. Bring both versions to your attorney review. Note: AI is often gender-biased and crafts terms beyond what is legally required. Push back on its output.
Step 3: Find a matrimonial or divorce lawyer in District of Columbia
Find a matrimonial or divorce attorney in D.C. Avvo, Findlaw, and Justia are good. Look for someone with 10+ years experience. Call or email and ask them how much to review your draft prenup and help with signing. Send them your draft.
Step 4: Meet your lawyer 4–6 months before the wedding
Our recommendation: sign the prenup before proposing. That way, you both get the legal work out of the way, and you know this is the right person to marry. Already proposed? 4–6 months before the wedding should leave you enough time to give your spouse 1–2 weeks to review the final draft and have it signed 30+ days before the wedding. D.C.'s Court of Appeals invalidated an agreement signed roughly an hour before the wedding in Norris v. Norris, 419 A.2d 982 (D.C. 1980) — last-minute pressure is one of the most successful challenge grounds in D.C.
Step 5: Review and sign the prenup with your attorney
D.C. requires only that the agreement be in writing and signed by both parties (D.C. Code § 46-502) — no witnesses or notarization required for validity. We HIGHLY recommend having the prenup reviewed and signed with an attorney, however, even if you don't have one, we recommend notarizing the signatures to strengthen the agreement against later challenges. Each party keeps a signed original, and so should each party's attorney.
District Of Columbia Prenuptial Agreement: Frequently Asked Questions (2026)
1. Are prenuptial agreements enforceable in D.C.?
Yes. D.C. enforces premarital agreements under the Uniform Premarital Agreement Act of 1995, codified at D.C. Code §§ 46-501 to 46-510, effective February 9, 1996. The statute presumes enforceability — the burden falls on the party challenging the agreement to prove it should not be enforced. D.C. courts review unconscionability only at the time of execution, not at divorce, providing strong predictability.
2. How much does a prenup cost in Washington, D.C.?
Attorney-drafted prenups in D.C. average $910 for drafting and $530 for review on a flat-fee basis (ContractsCounsel data). Hourly rates for experienced family law attorneys typically range from $350 to $650 per hour. Online services like PerfectPrenup cost a fraction of attorney rates and produce a draft you can take to a D.C. attorney for a much shorter, cheaper review.
3. What makes a prenup invalid in D.C.?
Under D.C. Code § 46-506, a prenup is unenforceable only if the challenger proves (1) involuntary execution, OR (2) it was unconscionable at execution AND lacked fair financial disclosure, no written waiver of disclosure, and no adequate independent knowledge of the other party's finances. Simon v. Smith, 273 A.3d 321 (D.C. 2022), requires both procedural and substantive unconscionability — an extremely high bar.
4. Does a prenup need to be notarized in D.C.?
No. D.C. Code § 46-502 requires only that the agreement be in writing and signed by both parties — no notarization, witnesses, or acknowledgment is required for validity. However, notarization is strongly recommended because it strengthens the evidentiary record against later voluntariness or forgery challenges.
5. How long before the wedding should I sign a prenup in D.C.?
D.C. has no statutory minimum, but signing 30+ days before the wedding is the practical floor. Norris v. Norris, 419 A.2d 982 (D.C. 1980), invalidated an agreement signed roughly an hour before the wedding due to coercive timing. Best practice: engage an attorney 4–6 months out and sign 60+ days before the wedding.
6. Can a prenup waive alimony in D.C.?
Yes, but with one limit. D.C. Code § 46-506(b) lets a court override an alimony waiver only if enforcement would make one party eligible for public assistance — and only "to the extent necessary to avoid that eligibility." Otherwise, full waivers are enforceable. Lake v. Lake, 756 A.2d 917 (D.C. 2000), confirms D.C. courts have broad discretion over alimony absent a valid prenup, making the waiver valuable.
7. Do I need a lawyer for a prenup in D.C.?
No. D.C. law does not require either party to have independent counsel. However, separate counsel for each party dramatically reduces challenge risk by neutralizing claims of involuntariness and unequal bargaining power. The DC Bar Lawyer Referral Service (202-780-2500) offers prescreened family law attorneys with $35 consultations.
8. Can a prenup determine child custody or child support in D.C.?
No. Under D.C. Code § 46-503(b), a child's right to support cannot be adversely affected by a prenup. Custody must always be determined by the child's best interests at the time of divorce. Including child support or custody terms could undermine the entire agreement — leave them out.
9. What can a prenup cover in D.C.?
Under D.C. Code § 46-503, prenups can cover property rights, division at separation/divorce/death, alimony modification or waiver, will and trust commitments, life insurance death benefits, choice of law, domestic partnership rights, and any other matter not violating public policy or criminal law. Domestic partners are expressly covered alongside spouses.
10. Can a stay-at-home spouse claim part of my pre-marital home in D.C.?
Yes — unless your prenup expressly waives it. Macklin v. Johnson, 268 A.3d 1273 (D.C. 2022), held that a homemaker spouse's substantial non-financial contributions can support an equitable claim against the other spouse's separately-titled real property. The wife in Macklin received 40% ($203,984) of the husband's pre-marital home. A D.C. prenup must include reciprocal waivers of homemaker-based equitable claims to fully protect separate real estate.
11. Can I modify or revoke a prenup after marriage in D.C.?
Yes. Under D.C. Code § 46-504, a prenup can be amended or revoked any time after marriage by a written agreement signed by both parties. No new consideration is required. Couples concerned about long-term enforceability can include a sunset clause that terminates the agreement after a set number of years.
12. Will a D.C. court second-guess my prenup at divorce?
No. D.C. is a "single review" jurisdiction — § 46-506(a) tests unconscionability only "when it was executed." Unlike states under the 2012 UPMAA (Colorado, North Dakota), D.C. courts cannot refuse enforcement based on changed circumstances or substantive hardship at divorce. This makes D.C. one of the more pro-enforcement jurisdictions in the country, provided the agreement was properly executed with disclosure.
