What Can and Can’t Be Included in a Prenup Under Iowa Law?

By Jeremy Feitelson, In Blog, 0 Comments

Prenuptial agreements are often misunderstood. While some people view them as rigid or one-sided, Iowa law allows couples to use prenups as practical planning tools that clarify expectations and reduce uncertainty. A well-drafted prenuptial agreement can protect assets, define financial responsibilities, and help both parties enter into marriage with transparency.

At the same time, not everything can legally be included in a prenuptial agreement. Understanding what Iowa courts will and will not enforce is critical to drafting a contract that holds up if challenged.

What a Prenuptial Agreement is Designed to Do

Under Iowa law, a prenuptial agreement is a written contract entered into before marriage that outlines how certain financial matters will be handled during the marriage and in the event of divorce or death. When properly drafted, these agreements allow couples to make decisions in advance rather than leaving them entirely to default state laws.

Prenup Under Iowa Law

Prenups are particularly common for individuals who own businesses, have significant premarital assets, expect inheritances, or are entering second marriages.

What Can Be Included in an Iowa Prenup

Iowa courts generally permit a wide range of financial provisions, provided the agreement is entered into voluntarily and with full disclosure.

  • Property Ownership and Division

A prenup may clearly define which assets are considered separate property and which will be treated as marital property. This often includes real estate, retirement accounts, investments, business interests, and personal property owned before the marriage.

Couples may also agree on how property acquired during the marriage will be divided if the marriage ends.

  • Debt Allocation

Prenuptial agreements can address responsibility for existing debts, such as student loans, business liabilities, or credit card balances. They may also specify how future debts will be handled, helping avoid disputes later.

  • Spousal Support Provisions

Iowa law allows prenups to address spousal support, including whether support will be paid, limited, or waived entirely. However, these provisions must be fair at the time of enforcement. If a spousal support waiver would leave one spouse destitute, a court may refuse to enforce it.

  • Estate Planning and Inheritance Rights

Prenuptial agreements can complement estate plans by clarifying inheritance rights and waiving specific statutory claims against an estate. This is especially important in blended families or when one spouse wants to preserve assets for children from a prior relationship.

What Cannot Be Included in an Iowa Prenup?

While prenuptial agreements offer flexibility, Iowa courts draw firm lines around specific issues.

  • Child Custody and Parenting Time

A prenuptial agreement cannot determine child custody or parenting time. Iowa courts decide these matters based on the child’s best interests at the time of separation or divorce, not on pre-marriage agreements.

  • Child Support Obligations

Parents cannot waive or limit child support in a prenuptial agreement. Child support is considered a child’s right, and Iowa courts retain full authority to set or modify support regardless of any prior agreement.

  • Illegal or Unconscionable Terms

Any provision that violates public policy or is fundamentally unfair may be struck down. This includes clauses that encourage divorce, penalize lawful behavior, or result from coercion or lack of disclosure.

What Makes a Prenup Enforceable in Iowa?

For a prenuptial agreement to be enforceable, it must meet specific legal requirements. Both parties must enter the agreement voluntarily, without pressure or last-minute demands. Full and honest financial disclosure is essential, and each party should have adequate time to review the terms.

Independent legal counsel is strongly recommended. While not strictly required, having separate attorneys significantly strengthens enforceability and helps ensure the agreement reflects informed consent.

Why Legal Guidance Matters When Drafting a Prenup

A poorly drafted prenup can create more problems than it solves. Ambiguous language, improper provisions, or procedural mistakes may render parts of the agreement unenforceable.
