North Carolina Prenuptial Agreement Laws: UPAA Rules (2026)

Prenuptial agreements are enforceable in North Carolina under the Uniform Premarital Agreement Act, Chapter 52B of the General Statutes. The agreement must be in writing and signed by both parties (G.S. 52B-3), and under G.S. 52B-7(a) a court will not enforce it if the challenger proves an involuntary signing, or an agreement that was unconscionable when signed combined with a lack of financial disclosure.

Jurisdiction scope: This article covers premarital agreements under North Carolina's Uniform Premarital Agreement Act (G.S. 52B-2 to 52B-10), with the related sections on spousal support (G.S. 50-16.6), property agreements (G.S. 50-20) and contracts between spouses (G.S. 52-10 and 52-10.1). Where it describes how the rules apply, it relies on the UNC School of Government's Trial Judges' Bench Book (2018 replacement chapter on spousal agreements). The statute quotations are the text of the North Carolina General Statutes as compiled in mid-2026; check the current code before relying on exact wording. It does not cover agreements signed before July 1, 1987, custody provisions, tax effects, the general statute of frauds or other states' law.

Are prenups enforceable in North Carolina?

Yes, when they meet the requirements of Chapter 52B. North Carolina enacted the Uniform Premarital Agreement Act as Chapter 52B of the General Statutes. G.S. 52B-10 directs that "The Uniform Premarital Agreement Act shall be applied and construed to effectuate its general purpose to make uniform among the states enacting it, the law on premarital agreements."

Which agreements the Act covers. According to the bench book, the Act applies to any premarital agreement executed on or after July 1, 1987 (S.L. 1987-473, sec. 3). Agreements signed earlier are governed by G.S. 52-10. This page covers agreements under Chapter 52B.

Formal requirements: writing and signatures

G.S. 52B-3 is two sentences: "A premarital agreement must be in writing and signed by both parties. It is enforceable without consideration."

G.S. 52B-5 adds that "A premarital agreement becomes effective upon marriage." If the wedding does not happen, the agreement does not take effect.

Acknowledgment. G.S. 52B-3 does not require notarization, witnesses or a formal acknowledgment, and the bench book states that a premarital agreement "does not have to be acknowledged." Acknowledgment does appear elsewhere in the property statutes. G.S. 50-20(d) allows spouses, "Before, during, or after marriage," to provide by written agreement for the distribution of marital and divisible property, using an agreement "duly executed and acknowledged in accordance with G.S. 52-10 and G.S. 52-10.1, or by a written agreement valid in the jurisdiction where executed." A lawyer licensed in North Carolina can explain whether that language matters for a particular agreement.

No lawyer or waiting period in Chapter 52B. G.S. 52B-3 through 52B-9 do not require that either party have independent legal counsel, and they do not set a waiting period between signing and the wedding. What they do test is voluntariness and disclosure, covered next.

When a North Carolina prenup is not enforceable (G.S. 52B-7)

G.S. 52B-7(a) places the burden on the party resisting the agreement. It provides that a premarital agreement "is not enforceable if the party against whom enforcement is sought proves" either of two things:

"(1) That party did not execute the agreement voluntarily; or (2) The agreement was unconscionable when it was executed and, before execution of the agreement, that party: a. Was not provided a fair and reasonable disclosure of the property or financial obligations of the other party; b. Did not voluntarily and expressly waive, in writing, any right to disclosure of the property or financial obligations of the other party beyond the disclosure provided; and c. Did not have, or reasonably could not have had, an adequate knowledge of the property or financial obligations of the other party."

Three points follow from that text:

• Voluntariness stands alone. An agreement signed involuntarily is unenforceable on that ground by itself.
• Unconscionability is judged at signing. The test asks whether the agreement was unconscionable "when it was executed," not whether it looks unfair years later. Under G.S. 52B-7(c), unconscionability is decided by the court as a matter of law.
• The disclosure conditions are joined by "and." For the unconscionability route, the challenger must show unconscionability plus all three disclosure conditions: no fair and reasonable disclosure, no written waiver of disclosure, and no adequate knowledge of the other party's finances.

Waiving alimony in a North Carolina prenup

A premarital agreement may modify or eliminate spousal support. G.S. 50-16.6(b) provides: "Alimony, postseparation support, and counsel fees may be barred by an express provision of a valid separation agreement, premarital agreement, or marital contract made pursuant to G.S. 52-10(a1) so long as the agreement is performed." The bench book notes this wording took effect June 19, 2013 (S.L. 2013-140).

The waiver has a limit. G.S. 52B-7(b) provides:

"If a provision of a premarital agreement modifies or eliminates spousal support and that modification or elimination causes one party to the agreement to be eligible for support under a program of public assistance at the time of separation or marital dissolution, a court, notwithstanding the terms of the agreement, may require the other party to provide support to the extent necessary to avoid that eligibility."

Before ordering that support, the court must find a dependent spouse and the requirements for postseparation support (G.S. 50-16.2A) or alimony (G.S. 50-16.3A). For how support is decided generally, see North Carolina alimony laws.

What a prenup can and cannot cover

G.S. 52B-4 lists subjects the parties may contract about, including:

• Property rights of the parties
• Disposition of property on separation, marital dissolution or death
• Modification or elimination of spousal support
• Making a will, trust or other arrangement to carry out the agreement
• Death benefits under a life insurance policy
• The choice of law governing the agreement
• Other matters that do not violate public policy or a statute imposing a criminal penalty

Child support. G.S. 52B-4(b) provides: "The right of a child to support may not be adversely affected by a premarital agreement." See North Carolina child support laws.

Custody. G.S. 52B-4 does not mention child custody, and this page does not cover custody provisions in a premarital agreement.

Changing or cancelling a prenup

G.S. 52B-6 provides: "After marriage, a premarital agreement may be amended or revoked only by a written agreement signed by the parties. The amended agreement or the revocation is enforceable without consideration."

Time limits and void marriages

Tolling. Under G.S. 52B-9, "Any statute of limitations applicable to an action asserting a claim for relief under a premarital agreement is tolled during the marriage of the parties to the agreement. However, equitable defenses limiting the time for enforcement, including laches and estoppel, are available to either party."

Void marriages. Under G.S. 52B-8, "If a marriage is determined to be void, an agreement that would otherwise have been a premarital agreement is enforceable only to the extent necessary to avoid an inequitable result."

Postnuptial agreements in North Carolina

Spouses can also contract after the wedding, but different rules apply than for a premarital agreement.

General contracts between spouses. G.S. 52-10(a) provides that "Contracts between husband and wife not inconsistent with public policy are valid." The same subsection provides that a contract or release between spouses made during the marriage does not affect either spouse's real property, or income from it accruing more than three years after the contract, unless it is in writing and acknowledged by both parties before a certifying officer.

Property agreements. G.S. 50-20(d) lets the parties provide for the distribution of marital and divisible property by a written agreement made before, during or after marriage, executed and acknowledged under G.S. 52-10 and 52-10.1 (or valid where executed), and states that "The agreement is binding on the parties."

Support waivers. G.S. 52-10(a1) validates a contract between spouses "made, with or without a valuable consideration, during a period of separation to waive, release, or establish rights and obligations to postseparation support, alimony, or spousal support." That subsection is about contracts made during a separation. It does not authorize a support waiver in a contract made during the marriage before any separation, and the bench book describes contracts made during the marriage, before separation and not in contemplation of separation, as able to address property rights but not support rights.

S.L. 2025-25 made technical wording changes to G.S. 52-10 in Part I, effective June 26, 2025. Part VI of the same act, effective October 1, 2025, also changed G.S. 50-20. Real property acquired by gift from the other spouse during the marriage is now separate property only if that intent is expressly stated in a written agreement separate from the conveyance, made in accordance with G.S. 50-20(d); other property acquired by gift from the other spouse needs that intent expressly stated in writing. G.S. 50-20(d) now also provides that the parties shall not provide for the distribution of marital or divisible property in an instrument of conveyance of real property. Section 48(e) of the act applies these changes to conveyances executed on or after its effective date. The quotations on this page are the text after those amendments. This page does not cover how those changes apply to a particular agreement or deed.

Property division without a prenup

North Carolina uses equitable distribution. G.S. 50-20(c) provides: "There shall be an equal division by using net value of marital property and net value of divisible property unless the court determines that an equal division is not equitable." The bench book notes that G.S. 50-20(d) expressly allows premarital agreements that dispose of property on divorce in place of equitable distribution. For the divorce process, see North Carolina divorce laws.

Frequently Asked Questions

Does a prenup need to be notarized in North Carolina?

G.S. 52B-3 requires only that a premarital agreement be in writing and signed by both parties, and the UNC School of Government bench book states that it does not have to be acknowledged. G.S. 50-20(d) refers to acknowledged agreements for property distribution, so a North Carolina lawyer can explain whether that matters for a given agreement.

Do both people need a lawyer for a prenup in North Carolina?

G.S. 52B-3 through 52B-9 do not require independent counsel. The enforceability test in G.S. 52B-7(a) turns on voluntariness and on unconscionability combined with a lack of financial disclosure.

Can a prenup waive alimony in North Carolina?

Yes. G.S. 50-16.6(b) allows alimony, postseparation support and counsel fees to be barred by an express provision of a valid premarital agreement so long as it is performed. G.S. 52B-7(b) lets a court order support anyway to the extent needed to keep a spouse from becoming eligible for public assistance.

Can a prenup decide child support in North Carolina?

No. G.S. 52B-4(b) provides that the right of a child to support may not be adversely affected by a premarital agreement.

Can you sign a prenup right before the wedding in North Carolina?

G.S. 52B-3 through 52B-9 set no waiting period. A party challenging the agreement can still try to prove under G.S. 52B-7(a)(1) that it was not signed voluntarily; this page does not cover how courts weigh timing.

Can a prenup be changed after the wedding in North Carolina?

Yes, but only by a written agreement signed by both spouses, and no consideration is needed (G.S. 52B-6).

Is North Carolina a community property state?

No. North Carolina divides property by equitable distribution under G.S. 50-20, which calls for an equal division of net marital and divisible property unless the court finds an equal division is not equitable.
