Under Utah Code § 81-3-202, the law explicitly allows prospective spouses to sign a premarital agreement, commonly known as a prenup, that modifies or completely eliminates spousal support, or alimony.
However, a signed waiver is not invincible. Utah courts may and will override an alimony waiver if enforcing it would leave one spouse so destitute that they become eligible for public assistance at the time of the divorce.
If you’re looking to create a prenup with this purpose in mind, the real challenge is ensuring the waiver can withstand legal scrutiny years or even decades later. Things like insufficient financial disclosure or signing the agreement under duress may render the entire document invalid.
With careful drafting that adheres to Utah’s Uniform Premarital Agreement Act (UPAA), you may create an enforceable agreement that protects your assets while ensuring a fair process for both parties. Prenuptial agreement lawyers at RCG Law Group handle the meticulous drafting and, when necessary, the litigation of these complicated contracts to ensure they accomplish their intended purpose.

Key Takeaways for Alimony Waivers in Utah Prenuptial Agreements
- Alimony waivers are legally permitted in Utah. The Utah Uniform Premarital Agreement Act explicitly allows couples to modify or eliminate spousal support in a prenup, giving you control over your financial future.
- Waivers must meet strict legal standards to be enforceable. A court can invalidate a waiver if it was signed involuntarily, was grossly unfair, or if there was a lack of full financial disclosure.
- A waiver cannot leave a spouse on public assistance. Utah law includes a safety net that allows a judge to order support if enforcing the waiver would make a spouse eligible for public aid at the time of divorce.
Utah’s Legal Framework for Alimony Waivers
Utah has adopted the Uniform Premarital Agreement Act (UPAA), which is contained in Title 81, Chapter 3 of the Utah Code. This set of laws gives couples significant power to define their own financial landscape in a marriage, shifting control from the state to the individuals.

Specifically, Utah Code § 81-3-203(d) grants you the right to contract for the modification or elimination of spousal support. This is true regardless of how long the marriage lasts or the difference in your incomes, as long as the correct legal procedures are followed during the creation of the agreement and whether a prenuptial agreement be renegotiated after marriage is a related question many couples explore.
For many high-net-worth individuals, this provides a layer of financial predictability. It helps avoid the uncertainty of a divorce court, where a judge’s view of the marital standard of living can lead to widely varying alimony awards.
Challenges to Enforceability: When Waivers Fail
The central fear for a wealthier spouse is whether the agreement will hold up under pressure. For the lower-earning spouse, the question is typically whether they unknowingly signed away their financial security.
Utah law provides a roadmap for challenging a prenup. Under Utah Code § 81-3-205(1), a party may ask the court to invalidate an alimony waiver by proving specific defects in its creation. This means a simple mistake made years before a divorce can have immense financial consequences.
At our firm, we analyze agreements against the three primary grounds for invalidation:
- Involuntariness: The agreement must be signed voluntarily. A court will look for signs of duress or coercion. For example, was the agreement presented just days before the wedding, leaving no real time for review? Was there a threat to call off the wedding if it wasn’t signed immediately? These situations could lead a judge to conclude the signature was not freely given.
- Unconscionability and Nondisclosure: This is a two-part test, reinforced in Utah case law like Keyes v. Keyes. An agreement may be thrown out if it was extremely one-sided (unconscionable) and the challenging party was not given a fair and reasonable disclosure of the other’s assets and debts before signing. Hiding assets is a fast track to getting an agreement voided.
- Lack of Waiver: If one party did not receive full financial disclosure, the agreement can still be valid if they voluntarily and expressly waived their right to that disclosure in writing. Without that written waiver, a lack of transparency may become a fatal flaw for the alimony provision.
The Public Assistance Safety Net
You may not create a private contract that forces the state to foot the bill for a person’s basic needs. This is a core principle of public policy that directly impacts alimony waivers.
Utah Code § 81-3-205(2) establishes a crucial safety valve. If enforcing an alimony waiver would cause a spouse to become eligible for a public assistance program (like food stamps or housing aid) at the time of the divorce, a court may step in. In such a case, the judge may override the prenup and order the other party to provide support.
Understand that this does not automatically reinstate a full alimony award based on the marital lifestyle. Instead, the court may order just enough support to prevent that spouse from needing to rely on public aid. When drafting these agreements, it is usually wise to include proactive safety net clauses to address this possibility and maintain control, rather than leaving it to a judge.
