The controlling statute & cases

What law governs prenups in Iowa?

Iowa prenuptial agreements are governed by the Iowa Uniform Premarital Agreement Act, found in Chapter 596 of the Iowa Code (Iowa Code ch. 596). The chapter explains how a prenuptial agreement must be created, which subjects it may address, how it can be changed, and the narrow circumstances in which a court may decline to enforce it. The Iowa Supreme Court has applied the act in decisions such as In re Marriage of Erpelding, 917 N.W.2d 235 (2018). The default rules a prenup is designed to change come from Iowa's divorce statutes, including Iowa Code § 598.21 on property division and § 598.21A on spousal support.

Is Iowa a UPAA state?

Yes, Iowa is a UPAA state. Iowa adopted its own version of the Uniform Premarital Agreement Act (UPAA) in 1991, with several changes from the original model law. Here is a list of what is different about Iowa’s UPAA:

• Iowa removed “income and earnings” from its definition of property.
• Iowa expressly requires both partners to sign any additional documents needed to enforce their agreement.
• Unlike the original UPAA, Iowa prohibits prenups from negatively affecting a spouse’s right to support. It also protects child support.
• Different reasons to reject a prenup: Iowa allows a court to refuse enforcement if the agreement was unconscionable (meaning extremely unfair) when signed. Inadequate financial disclosure is a separate ground, provided the person challenging the agreement also lacked, or could not reasonably have had, adequate knowledge of the other partner’s finances. They do not have to prove both unconscionability and inadequate disclosure together.

Requirements for an Iowa prenup

What are the requirements for a prenup in Iowa?

Under Iowa’s prenup act, a premarital agreement must be in writing and signed by both people, and it does not need separate consideration beyond the marriage itself. To withstand a challenge, the agreement must also have been signed voluntarily, and it cannot be unconscionable when signed in a situation where the challenging spouse was not given fair disclosure of the other's finances, did not waive that disclosure in writing, and had no other reasonable way of knowing the full financial picture.

Requirements:

• In writing
• Signed by both partners
• Signed voluntarily
• Fair disclosure of each partner’s finances, or a written waiver of it
• No terms that adversely affect a spouse’s or child’s right to support

Does a prenup need to be notarized in Iowa?

In Iowa, a prenuptial agreement does not need to be notarized. The Iowa Uniform Premarital Agreement Act sets forth the formal requirements for a valid premarital agreement, and notarization is not among them. Even though notarization is not mandatory in Iowa, having both signatures notarized is a smart, low-cost step because a notary's certificate gives both people a neutral record of who signed and when, which can matter if the signing is ever questioned.

Do both parties need a lawyer for a prenup in Iowa?

No, both parties do not need a lawyer for a prenup in Iowa. The act does not require either person to have independent counsel. However, whether each person had a fair chance to get legal advice still matters, because it bears on voluntariness and understanding if the agreement is attacked. Skipping a lawyer will not by itself invalidate an Iowa prenup, but it makes a challenge easier to build.

What makes a prenup invalid in Iowa?

An Iowa court may refuse to enforce a prenuptial agreement if the person challenging it proves that they did not sign voluntarily, or that the agreement was unconscionable when signed and they were not given fair disclosure of the other's property and financial obligations, did not waive that disclosure in writing, and could not reasonably have known those facts independently. An agreement that was not in writing, or was not signed by both people, never becomes enforceable at all.

How long before the wedding should I sign a prenup in Iowa?

Iowa attorneys generally suggest getting your prenup done 30 days before the wedding. Iowa courts have found agreements unenforceable when presented too close to the wedding.

For example, in In re Marriage of Maifield, the Iowa Court of Appeals held that a prenuptial agreement was unenforceable where the husband presented the agreement to the wife for signature the night before the wedding while she was entertaining dinner guests, which effectively prevented her from hiring an attorney and getting competent legal advice. (In re Marriage of Maifield, 796 N.W.2d 457 (2004)). By contrast, in Roberts v. Roberts, the Iowa Supreme Court held that a prenup executed approximately two weeks before the wedding was valid, suggesting that a period of roughly two weeks is generally sufficient. (Roberts v. Roberts as trustee of W. David Roberts Revocable Trust, 6 N.W.3d 730 (2024)).

What can & can't be in an Iowa prenup

Does cheating void a prenup in Iowa?

No, cheating does not void a prenup in Iowa. Infidelity does not automatically cancel a prenuptial agreement. There is no state-listed ground for invalidating a prenup under infidelity/adultery. In fact, Iowa is a no-fault state: the sole ground for dissolution is that the marriage has broken down to the point that its legitimate objects have been destroyed (Iowa Code § 598.5), and courts do not look to fault when dividing property or deciding support.

Are infidelity clauses enforceable in Iowa?

According to Iowa prenup lawyer AJ Skogerson, “In Iowa, clauses imposing financial penalties for infidelity are unenforceable, so I encourage couples to focus on what a prenup can do well: clarify financial expectations and help them enter marriage with greater understanding and confidence.” Some couples may still choose to include infidelity clauses in their prenup, even though they are not enforceable. Not all attorneys will agree to sign off on these types of clauses, though, so be careful when adding these.

Can a prenup include child custody in Iowa?

No, a prenup cannot include child custody in Iowa. Custody is decided under the best-interest factors in Iowa Code § 598.41, based on the child's circumstances when custody is actually at issue. A prenup signed before children exist cannot predetermine custody or visitation, and the act also protects a child's right to support from being reduced by contract.

Can a prenup protect a business in Iowa?

Yes, prenups can protect businesses in Iowa. The Iowa prenup act lets couples contract about their rights in property whenever and wherever acquired, which includes business interests. This can matter a good deal in Iowa, because Iowa courts generally divide property a spouse brought into the marriage, giving that spouse credit for its value at the time of the wedding rather than excluding it. A prenup can state that a business owned before the marriage, along with its growth, income, debt, and any eventual sale proceeds, stays the separate property of the owner and is not divided in a divorce.

Can a prenup protect inheritance in Iowa?

Yes, a prenup can protect a future inheritance in Iowa. Iowa Code § 598.21 provides that inherited property and gifts to one spouse generally belong to that spouse and are not divided, unless refusing to divide them would be inequitable to the other spouse or the children. That exception leaves room for argument, particularly if inherited funds were mixed with marital funds. A prenuptial agreement lets a couple confirm in writing that inherited and gifted assets, and their growth, remain separate no matter what happens during the marriage. In fact, about 93% of Iowa users on HelloPrenup choose to keep their future inheritances separate.

Marital property in Iowa

Is Iowa a community property state?

No, Iowa is not a community property state. Iowa divides property under an equitable distribution model. Instead of assuming everything acquired during the marriage is owned equally, a court divides the couple's property in a way it considers equitable, which is often close to an even split but does not have to be.

How is property divided in a divorce in Iowa without a prenup?

Under Iowa Code § 598.21, an Iowa court divides the property of the parties equitably after considering factors including the length of the marriage, the property each spouse brought into it, each spouse's contributions to the marriage, including as a homemaker, the age and health of each spouse, each spouse's earning capacity, and the other economic circumstances of the parties. A feature that sets Iowa apart is that property owned before the marriage is generally included in the division, with the court giving credit to the spouse who brought it in, while inherited and gifted property is generally set aside to its owner. For example, a home bought prior to the marriage could be considered marital property and divided regardless of whose name is on the deed.

Does a prenup override equitable distribution in Iowa?

Yes, a prenup in Iowa can override equitable distribution laws in the state. A valid agreement lets a couple replace the court's discretionary analysis with their own terms, deciding in advance which assets are separate, how future earnings and purchases are classified, and how jointly built wealth is divided. Because Iowa's default includes premarital property in the pool, a prenup can protect more here than in states that automatically exclude it.

What is separate property in Iowa?

Iowa does not use a single catch-all statutory category of separate property. Inherited property and gifts to one spouse are generally set aside to that spouse under Iowa Code § 598.21, but property owned before the marriage is ordinarily part of the property a court may divide, with credit given for its premarital value. A prenup is the most dependable way to define in advance what stays separate and to avoid arguing about it later.

Spousal support in Iowa

Can a prenup waive spousal support in Iowa?

No, you cannot waive spousal support in Iowa prenuptial agreements. Under Iowa law, a spousal support waiver in a prenuptial agreement is not enforceable. Iowa Code § 596.5(2) expressly prohibits Iowa prenup agreements from affecting a spouse's right to support, and Iowa courts have consistently held that alimony waiver provisions in prenuptial agreements executed on or after January 1, 1992, are invalid and unenforceable.

How is spousal support determined in Iowa without a prenup?

Without a prenup, an Iowa court decides spousal support under Iowa Code § 598.21A, which recognizes several types of support, including traditional, rehabilitative, and reimbursement alimony, and which directs the court to weigh factors such as:

• The length of the marriage
• The age and physical and emotional health of each spouse
• The distribution of property made in the divorce
• The educational level of each spouse and the time needed to gain further education or training
• The earning capacity of each spouse
• The feasibility of the spouse seeking support becoming self-supporting at a reasonably comparable standard of living
• Tax consequences to each spouse

How much does a prenup cost in Iowa?

How much does a prenup cost in Iowa?

A straightforward Iowa prenup drafted and reviewed by two Iowa prenup lawyers usually costs between $2,000 and $5,500 per couple. Business ownership, real estate in several states, or extended negotiation will push the total higher. We spoke with Iowa prenup lawyer AJ Skogerson, who told us: “HelloPrenup’s flat-fee approach helps couples plan for that expense at a reasonable cost while still having separate attorneys review and refine their agreement. The combination of predictable pricing and individual legal guidance can make the process more approachable.”

What is the cheapest way to get a prenup in Iowa?

The most affordable route to an Iowa prenup is usually to create the agreement on an online prenup platform and then pay an Iowa-licensed attorney a flat fee to review it, rather than paying hourly for a lawyer to draft from scratch. HelloPrenup allows Iowa-based couples to complete a guided questionnaire and then connect with a licensed attorney in the state for questions, review, and explanation.

How much does a prenup lawyer cost in Iowa?

The average Iowa attorney charges $250 per hour. Attorneys handling prenuptial agreements in Iowa typically charge between $200 and $350 per hour, with rates higher in Des Moines. A simple agreement with simple assets takes fewer hours than one involving business valuations, trusts, or heavy back-and-forth between two attorneys.

How to get a prenup in Iowa

How do I get a prenup in Iowa?

Couples in Iowa usually choose between two paths: each person hires their own attorney, with one drafting and the other reviewing and negotiating, or the couple uses an online platform, compliant with Iowa laws, to generate the agreement and then adds attorney review. The two-attorney route is generally slower and costlier because drafting time is billed on top of review. Starting online and using Iowa-licensed attorneys for review is typically faster and cheaper.

Can I write my own prenup in Iowa?

Yes, you can technically write your own prenup, at your own risk. Nothing in the Iowa prenup act requires a lawyer. The risk is that a self-drafted agreement with vague wording, conflicting terms, or improper financial disclosure is easier to challenge, and Iowa's practice of including premarital property in the divisible estate means a poorly worded agreement may not protect what the couple meant to protect. Some couples may choose to draft the substance themselves and then have an attorney review it before they sign.

How long does it take to get a prenup in Iowa?

It depends on how you choose to get a prenup. If you’re going the two-attorney route, it usually takes a few weeks to a couple of months. With an online prenup platform, it can take less time, even as little as a few hours. The slowest part is typically gathering the financial disclosure, such as account statements, property records, and debts. Also, if you’re hiring attorneys, working with their availability can add time.

Do I need a lawyer to get a prenup in Iowa?

No, you don’t need a lawyer to get a prenup in Iowa. However, you should have the opportunity to hire a lawyer. For example, in In re Marriage of Maifield, the Iowa Court of Appeals threw out a prenuptial agreement because the wife was not given a meaningful opportunity to seek legal counsel. The husband presented the agreement to the wife for signature on the eve of the wedding when she was entertaining dinner guests, effectively precluding her from seeking competent advice on the legal implications of the agreement (In re Marriage of Maifield, 796 N.W.2d 457 (2004)).

Caselaw & enforceability

Are prenups enforceable in Iowa?

Yes, prenups are enforceable in Iowa. Iowa enforces prenuptial agreements that satisfy its Uniform Premarital Agreement Act requirements. The person seeking to avoid enforcement carries the burden of proving that the agreement was not signed voluntarily, or that it was unconscionable when signed and paired with inadequate disclosure that was not waived.

How hard is it to break a prenup in Iowa?

It is hard to break a prenup in Iowa. The challenger must prove one of the act's narrow grounds rather than simply argue that the deal was unfair or has worked out badly. Regret, standing alone, is not enough to undo an agreement that was properly signed and fairly disclosed under Iowa prenup laws.

Can a judge throw out a prenup in Iowa?

Yes, a judge can throw out a prenup in Iowa, but only on the grounds the Iowa prenup act recognizes. Unconscionability is a question the court decides as a matter of law, and the court will look at whether the signing was voluntary and whether both people had a fair picture of each other's finances. An agreement that satisfies both is difficult to unwind. For example, a judge in In re Marriage of Maifield threw out a prenup because the husband didn’t give the wife enough time to find an attorney to have her review it. He rushed her into the prenup the night before the wedding. (In re Marriage of Maifield, 796 N.W.2d 457 (2004)).

What can void a prenup in Iowa?

An Iowa premarital agreement may be unenforceable if:

• It was not in writing or not signed by both people
• It was not signed voluntarily
• It was unconscionable when signed and the challenger lacked fair disclosure that was not waived in writing
• A provision violates public policy or requires an illegal act

Outside those situations, Iowa courts generally hold couples to what they signed.

Duration & after-marriage

How long does a prenup last in Iowa?

A valid Iowa prenup agreement takes effect on marriage and stays in force for the life of the marriage unless the couple builds in an end date. Some couples add a “sunset clause” that ends all or part of the agreement on a given anniversary, such as the 20th wedding anniversary, in order to recognize that a long marriage tends to blend finances in ways the original terms did not anticipate.

Can you get a prenup after marriage in Iowa?

No, you cannot get a prenup after marriage in Iowa. In fact, Iowa is one of a handful of states that do not recognize postnuptial agreements at all. The Iowa legislature has authorized prenup agreements through a dedicated statutory framework, but has made no equivalent statute for postnups. Iowa courts have consistently treated postnuptial agreements with skepticism, and the most recent Iowa Supreme Court decision confirms that key categories of postnuptial agreements are invalid under Iowa law.

Can you change a prenup in Iowa?

No, you cannot amend a prenup in Iowa. Iowa's premarital agreement law states that after marriage, a prenuptial agreement may be revoked only. The statute does not include any right to amend (Iowa Code § 596.7). This is a deliberate departure from the Uniform Premarital Agreement Model Act, which expressly provides that after marriage, a premarital agreement may be amended or revoked by a written agreement signed by the parties. Iowa's legislature chose to omit the right to amend, and Iowa courts do not search for meaning beyond the statute's express terms (In re Marriage of Hansen, 924 N.W.2d 873 (2018)).

Cross-border & recognition

Is a prenup signed in another state valid in Iowa?

Iowa's act lets couples choose which state's law governs their agreement, and Iowa courts generally honor a reasonable choice. An Iowa court asked to enforce an out-of-state prenup will still check whether it meets Iowa's baseline requirements and whether any term offends Iowa public policy.

For example, in Hussemann ex rel. Ritter v. Hussemann, the Iowa Supreme Court applied Florida law, rather than Iowa law, to determine the validity of a postnuptial agreement that had been negotiated and executed in Florida. The agreement contained a choice-of-law provision specifying that Florida law applied to any dispute, and it included a waiver of the wife's spousal elective share of the husband's trust. The court found that Iowa did not have a materially greater interest than Florida in the dispute, and therefore Florida law governed. The court noted that the couple lived in Florida at the time of signing the agreement, the parties were married in Florida, and the trust at issue was formed under Florida law. (Hussemann ex rel. Ritter v. Hussemann, 847 N.W.2d 219 (2014)).

What happens to my Iowa prenup if I move to another state?

That depends on how the new state treats choice-of-law clauses and its own prenup agreement rules. Because Iowa follows the UPAA, many other UPAA states will recognize an Iowa choice-of-law clause without much friction, while states with a different framework may honor the clause but apply their own public policy limits. A clear choice-of-law provision improves the odds that Iowa law keeps governing the agreement, though it is not a guarantee.
