Prenuptial & Marital Property Agreements

Why These Agreements Matter — Especially in Second Marriages

Many couples entering a second or later marriage come with a more complicated financial picture than they had the first time: property they owned before the marriage, children from a prior relationship whose inheritance they want to protect, a business built over years, or retirement accounts and real estate that represent decades of hard work.

Without a written agreement, Utah's marital property laws may classify and distribute those assets in ways neither spouse intended — whether at divorce or at death. A prenuptial or marital property agreement puts the couple in control of those decisions instead of leaving them to a default legal framework.

This is not just a document for the wealthy. Any couple who enters a marriage with property, children, or financial obligations they want to protect has a reason to consider one.

What a Utah Prenuptial Agreement Can — and Cannot — Cover

Under the Utah Uniform Premarital Agreement Act (Utah Code § 81-3), the parties to a prenuptial agreement have wide latitude to define their legal rights and obligations. Both what the agreement covers and what it excludes are governed by statute.

Prenuptial vs. Marital Property Agreements

The most common question is the difference between a prenuptial agreement (executed before the marriage) and a marital property agreement (sometimes called a postnuptial agreement, executed after the wedding). Both can address the same subjects — property characterization, spousal support, business interests, and estate planning coordination — but the timing and legal context differ.

Prenuptial Agreement

Executed and signed before the marriage, a prenuptial agreement becomes effective on the date of the wedding. It is the more common choice because it is entered into when both parties have full freedom of action and the agreement cannot be challenged on the basis of changed circumstances in the marriage.

To strengthen enforceability, both parties should have the opportunity for independent legal review before signing, and the agreement should be signed well in advance of the wedding — not under the pressure of an imminent ceremony.

Marital Property Agreement

A marital property agreement (postnuptial agreement) is entered into after the couple is already married. These are particularly useful when:

• A prenuptial agreement was not in place and the couple wants to clarify property rights mid-marriage
• One spouse starts a business after the wedding and wants to define its ownership
• The couple receives a significant inheritance and wants to confirm its character as separate property
• Circumstances change and the couple wants to update their written understanding

Like prenuptial agreements, marital property agreements must be voluntary, in writing, and supported by adequate financial disclosure between the parties to be enforceable.

How This Coordinates with Your Estate Plan

A prenuptial or marital property agreement does not replace an estate plan — it works alongside it. The agreement defines how property is characterized and what each party's rights are during the marriage and at divorce. Your will and trust control what happens to that property when you die.

The two documents need to be consistent with each other. A prenuptial agreement that designates certain assets as separate property should be mirrored by a trust that holds and distributes those assets accordingly. A provision in the agreement that directs specific property to children from a prior relationship needs a corresponding will or trust provision to carry it out.

Many clients come to me for their estate plan and realize during our discussions that a marital property agreement would address questions their estate plan alone cannot answer — particularly around what happens to property during their lifetime rather than only at death. Others come for a prenuptial agreement and discover the value of building a complete estate plan at the same time.

Wherever you are starting, building these documents together — or reviewing them together if one already exists — produces a more coherent and reliable result. For clients whose primary concern is protecting assets from future creditors or legal claims, coordinating the agreement with proper ownership structures adds another layer of protection.

What to Expect from the Process

Every prenuptial and marital property agreement I draft starts with a clear conversation about what each party owns, what they want to protect, and what they are building together going forward. The process generally involves:

• Initial consultation — understanding your situation, goals, and the assets involved
• Financial disclosure — both parties provide a fair and complete picture of their assets, debts, and income; this is essential to enforceability
• Drafting — I prepare the agreement based on your agreed-upon terms
• Review — both parties review the draft; the other party should have independent legal counsel review before signing
• Execution — both parties sign the agreement, well in advance of the wedding if possible
• Estate plan coordination — if a will and trust are needed, we draft them to align with the agreement's terms

Frequently Asked Questions

• What can a prenuptial agreement cover in Utah?+
  Under the Utah Uniform Premarital Agreement Act (Utah Code § 81-3), a prenuptial agreement can address property ownership and characterization as separate or marital, rights to specific assets at divorce or death, spousal support obligations, disposition of property through the estate plan, business ownership interests, and any other matter not in violation of Utah law or public policy. It cannot predetermine child support or child custody, which courts decide at the time of any dispute.
• Are prenuptial agreements enforceable in Utah?+
  Yes. Under Utah Code § 81-3, a prenuptial agreement is enforceable if it is in writing, signed by both parties, and becomes effective upon marriage. A court may decline to enforce it if the challenging party proves it was not voluntary, or that it was unconscionable when executed and not preceded by adequate financial disclosure. Allowing both parties time to review the agreement with independent counsel before signing significantly strengthens enforceability.
• Can a prenuptial agreement address what happens when I die?+
  Yes. A prenuptial agreement can specify property rights at death — including directing that separate property passes to children from a prior relationship rather than to the surviving spouse. This is one of the most important uses for people entering a second marriage. The agreement should be coordinated carefully with your will and trust to avoid conflicts between the documents.
• What is the difference between a prenuptial and a postnuptial agreement?+
  A prenuptial agreement is executed before the marriage; a postnuptial (or marital property) agreement is entered into after the couple is already married. Both can address property characterization, spousal support, business interests, and estate planning coordination. Postnuptial agreements are especially useful when circumstances change after the wedding — a new business, an inheritance, or a significant shift in the couple's financial picture.
• Do both parties need their own attorney?+
  Utah does not legally require both parties to have separate attorneys, but independent legal counsel for both parties significantly strengthens enforceability and ensures both parties understand what they are signing. I represent one party in drafting and negotiating the agreement; the other party should have their own attorney review it before signing.
