Rhode Island Prenuptial Agreement Laws: Requirements and Enforcement

Yes. Rhode Island enforces prenuptial agreements under its Uniform Premarital Agreement Act, chapter 15-17 of the General Laws, and its enforcement test is demanding for the challenger. Under R.I. Gen. Laws 15-17-6, a spouse who wants to avoid the agreement must prove both that they did not sign voluntarily and that it was unconscionable without fair disclosure, each by clear and convincing evidence.

Jurisdiction scope: This article covers premarital agreements under Rhode Island's Uniform Premarital Agreement Act, R.I. Gen. Laws 15-17-1 to 15-17-11, with a note on property division under 15-5-16.1. It does not cover Rhode Island case law on prenups, postnuptial agreements, which agreements the Act applies to by signing date, or other states' law. It is not a template and does not suggest terms.

Are prenups enforceable in Rhode Island?

Generally, yes. Section 15-17-10 provides: "This chapter may be cited as the Uniform Premarital Agreement Act." The chapter sets the formal requirements, the grounds for refusing enforcement, and limits on support waivers and child support.

Rhode Island's version places a heavy burden on the person challenging the agreement, as the next sections explain.

Formal requirements for a Rhode Island prenup

Section 15-17-2 provides: "A premarital agreement must be in writing and signed by both parties." The agreement is enforceable without consideration, and under 15-17-4 it becomes effective upon marriage. Rhode Island's statute of frauds, 9-1-4(2), also bars an action on an agreement made upon consideration of marriage unless it, or a note or memorandum of it, is in writing and signed by the party to be charged.

Section 15-17-2 does not mention notarization or witnesses. This page does not cover whether any other Rhode Island statute adds requirements for particular terms or property, such as real estate. A lawyer licensed in Rhode Island can review an agreement before it is signed.

When a Rhode Island prenup is not enforceable

Section 15-17-6(a) requires the party resisting enforcement to prove two things, joined by "and":

"(1) That party did not execute the agreement voluntarily; and (2) The agreement was unconscionable when it was executed and, before execution of the agreement, that party:"

The second element continues with three disclosure conditions. The challenger must show that, before signing, they were not given fair and reasonable disclosure, did not voluntarily and expressly waive disclosure in writing, and did not have, or reasonably could not have had, adequate knowledge of the other party's property or obligations.

Because the two elements are joined, proving only that the agreement was signed under pressure, or only that it was one-sided without disclosure, does not satisfy 15-17-6(a). Proving both is required.

Burden of proof. Under 15-17-6(b), the burden as to each element "must be proven by clear and convincing evidence." Under 15-17-6(d), whether the agreement is unconscionable is decided by the court as a matter of law.

Counsel and timing. Section 15-17-6 does not list independent legal counsel or a waiting period before the wedding as a condition of enforcement. This page does not cover how Rhode Island courts weigh those facts when deciding voluntariness or unconscionability.

Spousal support waivers in Rhode Island

Under 15-17-6(c), if modifying or eliminating spousal support would make a party eligible for public assistance, "a court, notwithstanding the terms of the agreement, may require the other party to provide support to the extent necessary to avoid that eligibility."

What a Rhode Island prenup cannot do

Section 15-17-3(b) provides: "The right of a child to support may not be adversely affected by a premarital agreement." For how child support is set, see Rhode Island child support laws.

This page does not cover whether a premarital agreement can address child custody in Rhode Island.

If the marriage turns out to be void

Under 15-17-7, 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."

Changing or cancelling a prenup after marriage

Section 15-17-5 provides: "After marriage, a premarital agreement may be amended or revoked only by a written agreement signed by the parties." The amendment or revocation is enforceable without consideration.

Time limits on prenup claims

Section 15-17-8 provides: "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." The equitable defenses of laches and estoppel remain available, so delay can still matter.

Postnuptial agreements in Rhode Island

Chapter 15-17 addresses premarital agreements, signed before marriage. This page does not cover how Rhode Island treats agreements spouses sign after the wedding, other than amendments to a premarital agreement under 15-17-5. The Family Court's jurisdiction covers antenuptial agreements and other contracts between persons who, when they signed, were husband and wife or planned to marry (8-10-3(a)). Ask a Rhode Island lawyer about a postnuptial agreement.

Rhode Island property division without a prenup

Without an agreement, the court in a divorce "may assign to either the husband or wife a portion of the estate of the other" under 15-5-16.1(a), considering the factors listed there.

Property held in one spouse's name before the marriage, inherited property, and gifts from a third party generally may not be assigned; the statute provides, "The court shall not assign property or an interest in property which has been transferred to one of the parties by gift from a third party before, during, or after the term of the marriage." Appreciation from either spouse's efforts and income from premarital property may be assigned. See Rhode Island divorce laws.
