District of Columbia: Prenuptial Agreement Requirements
The short answer
The District of Columbia's Uniform Premarital Agreement Act requires a writing signed by both prospective spouses, needs no consideration, and makes the agreement effective upon marriage. There is no statutory notary, witness, counsel, or waiting-period requirement. Enforcement fails for involuntary execution or for execution-time unconscionability combined with all three disclosure failures. Spousal support may be modified or eliminated subject to a public-assistance safety valve, while child support cannot be adversely affected and custody remains controlled by the child's best interests.

| Governing law and framework | Uniform Premarital Agreement Act of 1995 for agreements executed on or after February 9, 1996 (D.C. Code §§ 46-501 to -510) |
|---|---|
| Writing, signature, and effect | Writing signed by both; no consideration; effective upon marriage (§§ 46-501(3), 46-502, 46-504) |
| Execution formalities | No statutory notary, acknowledgment, witness, attestation, or recording requirement; writing and both signatures are the formalities (§ 46-502) |
| Financial disclosure and waiver | Fair and reasonable disclosure; voluntary express written waiver or actual/reasonably available adequate knowledge are alternatives within the combined unconscionability test (§ 46-506(a)(2)) |
| Independent counsel and timing | No statutory independent-counsel/advisement requirement and no fixed final-draft or pre-wedding period; voluntary execution remains required (§§ 46-502, 46-506(a)(1)) |
| Fairness standard and source | Statute — involuntary execution defeats enforcement; execution-time unconscionability plus all three disclosure failures also defeats it; the court decides unconscionability (§ 46-506) |
| Spousal-support limits | May modify or eliminate support; court may order only enough support to avoid public-assistance eligibility caused by the term at separation or dissolution (§§ 46-503(a)(4), 46-506(b)) |
| Child and public-policy limits | Cannot adversely affect child support; custody stays with the court under best interests; other terms cannot violate public policy or a criminal statute (§§ 46-503(a)(8), (b), 16-914) |
| Amendment and revocation | After marriage, only by a written agreement signed by both; amendment or revocation needs no consideration (§ 46-505) |

Requirements one by one
The District uses the Uniform Premarital Agreement Act
D.C. Law 11-82 enacted the Uniform Premarital Agreement Act of 1995, now
codified at D.C. Code §§ 46-501 through 46-510. D.C. Code § 46-510 directs uniform
construction, and § 46-509 makes the chapter applicable to agreements executed
on or after February 9, 1996.
The chapter also covers prospective domestic partners, but this page focuses on
ordinary agreements between prospective spouses.
Both signatures and marriage are separate requirements
Section 46-502 requires a writing signed by both parties and makes it
enforceable without consideration. Section 46-501(3) defines the agreement as
one made in contemplation of marriage and intended to take effect upon marriage;
§ 46-504 confirms that marriage is the event that activates it.
The paired definitions at § 46-501(3)-(4) cover the agreement and the broad
property interests it may address.
A signed document therefore exists before the wedding, but it becomes a
premarital agreement with operative effect when the marriage occurs.
The statute does not require a notary or witnesses
The section titled “Formalities,” § 46-502, requires the writing and both
signatures. Chapter 5 adds no notary, acknowledgment, witness, attestation,
oath, or recording requirement for basic validity between the parties.
Notarization may help authenticate signatures, but it is not part of the act's
stated formation rule.
Disclosure uses a combined statutory test
Section 46-506(a)(2) does not make imperfect disclosure a standalone reason to
void every agreement. The challenging party must show that the agreement was
unconscionable when executed and establish all three listed circumstances: no
fair and reasonable disclosure, no voluntary express written waiver of further
disclosure, and no actual or reasonably available adequate knowledge.
The statute says the waiver must be express and in writing. It does not say the
waiver must be in a document separate from the agreement.
Counsel and timing are not fixed statutory formalities
Sections 46-501 through 46-510 impose no mandatory independent counsel, written
counsel advisement, fixed final-draft review period, or minimum number of days
between signing and the wedding. That statutory silence does not eliminate
§ 46-506(a)(1)'s separate requirement of voluntary execution.
The District's statute should not be confused with jurisdictions that condition
a support waiver on counsel or mandate a pre-wedding countdown.
The statute supplies the fairness test
The fairness source is statutory. Under § 46-506(a), involuntary execution is
one independent route to nonenforcement. The second route requires
unconscionability when the agreement was executed plus all three disclosure
failures. The court decides unconscionability as a matter of law.
The statute does not state a general divorce-time unconscionability or
changed-circumstances second look. Its support provision has a narrower express
override tied to public-assistance eligibility.
A support waiver has a public-assistance safety valve
Section 46-503(a)(4) permits modification or elimination of spousal support.
If that term causes a party to qualify for public assistance at separation or
dissolution, § 46-506(b) permits the court to order support only to the extent
necessary to avoid that eligibility.
That safety valve is narrower than a free-standing authority to rewrite any
support term that later appears harsh.
Child support and custody remain outside private control
Section 46-503(b) says a premarital agreement may not adversely affect a
child's support right. D.C. Code § 16-916.01(a) applies the child-support guideline and
allows later modification of an agreement's support provision after a
substantial and material change.
Custody remains a judicial best-interests determination under § 16-914(a)(1). The
act's general subject-matter clause also prohibits provisions that violate
public policy or a statute imposing a criminal penalty.
Changes after marriage require another signed writing
Under § 46-505, a premarital agreement may be amended or revoked after marriage
only through a written agreement signed by both parties. The amendment or
revocation needs no consideration.
The statute does not add notarization to that change mechanism.
What trips people up
- The disclosure elements are conjunctive. Execution-time
unconscionability and all three disclosure failures are required under
§ 46-506(a)(2). - The support override is limited. It reaches only the amount necessary to
avoid public-assistance eligibility caused by the modification or waiver. - The chapter numbers start at 46-501. References to a D.C. premarital act
at §§ 46-701 or 46-706 are wrong.
Common questions
Does a D.C. prenup need notarization?
No. Section 46-502 requires a writing signed by both parties. It does not list
a notary or witnesses as validity formalities.
Is independent counsel required?
The act contains no express counsel mandate or written counsel-waiver form.
Voluntary execution remains necessary, and separate advice is prudent, but the
statute does not make actual counsel a universal formation requirement.
What if the marriage is later declared void?
D.C. Code § 46-507 generally limits enforcement to what is necessary to avoid an
inequitable result. The agreement can instead expressly provide that it remains
enforceable if the marriage is later determined to be void.
