Marital and Nonmarital Property in Minnesota

Last reviewed November 3, 2026

Marital and nonmarital property in Minnesota are the two categories a court uses to sort a couple’s assets in a divorce. Marital property is divided between the spouses, while nonmarital property generally stays with the spouse who owns it. The definitions appear in Minn. Stat. § 518.003, subd. 3b, and the division rules in Minn. Stat. § 518.58. This page explains how property is classified, how nonmarital claims are proven, and how the court divides the marital estate. It is part of the site’s guide to divorce in Minnesota.

What Counts as Marital Property

Marital property is real or personal property that either spouse acquires during the marriage and before the valuation date. It expressly includes vested public and private pension benefits (§ 518.003, subd. 3b).

Title does not control the result. Property acquired during the marriage is presumed marital, whether it is held in one name, in joint tenancy, or in another form of co-ownership. Accordingly, a 401(k) in one spouse’s name, or a car titled to one spouse, is ordinarily marital if acquired during the marriage.

The Five Types of Nonmarital Property

The marital presumption is overcome by showing that the property falls into one of five categories (§ 518.003, subd. 3b(a)–(e)). Nonmarital property is property that:

1. was received as a gift, bequest, devise, or inheritance from a third party to one spouse alone;
2. was acquired before the marriage;
3. was acquired in exchange for, or is the increase in value of, other nonmarital property;
4. was acquired by a spouse after the valuation date; or
5. is excluded by a valid antenuptial agreement.

Gifts between spouses are not on the list. A gift from one spouse to the other during the marriage is therefore generally marital property. In addition, an antenuptial agreement or a postnuptial agreement can change these default rules.

Proving a Nonmarital Claim

The spouse claiming that property is nonmarital carries the burden of proof. The standard is a preponderance of the evidence. The Minnesota Supreme Court confirmed this standard in Antone v. Antone, 645 N.W.2d 96 (Minn. 2002). That decision also held that classification is a question of law, which appellate courts review independently.

Tracing

Nonmarital funds often change form during a marriage. For example, an inheritance may be deposited in a bank account and later used for a down payment. To keep its nonmarital character, the money must be traced from its source to the current asset. Bank statements, closing documents, and estate records are the usual evidence.

Commingling

When nonmarital money is mixed with marital money and cannot be traced, it may lose its nonmarital status. Keeping inherited or premarital funds in a separate account, in one name, makes tracing much easier.

Appreciation of Nonmarital Property

An asset can contain both marital and nonmarital interests. A common example is a home that one spouse owned before marriage, then paid down with marital earnings.

Minnesota courts apportion such assets using the formula from Schmitz v. Schmitz, 309 N.W.2d 748 (Minn. 1981). Broadly, the nonmarital share of the asset’s value grows in proportion to the nonmarital contribution. Increases caused by market forces, such as inflation, follow the ownership share. In contrast, increases caused by marital effort or marital funds are marital. The site’s page on the house in a divorce covers real estate in more detail.

The Valuation Date

Marital assets are valued as of the day of the initially scheduled prehearing settlement conference (§ 518.58, subd. 1). The parties may agree on another date, or the court may choose one with specific findings. If an asset’s value changes substantially before final distribution, the court may adjust it. Property acquired after the valuation date is nonmarital.

How Marital Property Is Divided

The court must make a “just and equitable” division of marital property, without regard to marital misconduct (§ 518.58, subd. 1). Equitable does not always mean equal, although an equal division is common. The court weighs factors such as:

• the length of the marriage and any prior marriage;
• each spouse’s age, health, occupation, income, and employability;
• each spouse’s needs, liabilities, and opportunity to acquire future assets; and
• each spouse’s contribution to the property, including work as a homemaker.

The statute conclusively presumes that each spouse made a substantial contribution to income and property while they lived together. For retirement assets specifically, see Retirement Accounts and Divorce.

When Nonmarital Property May Be Shared

Nonmarital property is not always untouchable. If one spouse’s resources, including that spouse’s share of the marital property, are so inadequate as to cause unfair hardship, the court may award up to one-half of the other spouse’s nonmarital property (§ 518.58, subd. 2). The court must support that award with findings. This remedy is exceptional and is not available for property excluded by an antenuptial agreement.

Hiding or Wasting Assets

During a divorce, and when one is contemplated, each spouse owes the other a fiduciary duty regarding marital assets. If a spouse transfers, conceals, or disposes of marital property outside the usual course of business or the necessities of life, the court must compensate the other spouse (§ 518.58, subd. 1a). The court may charge the full value of the asset, plus a fair return, to the spouse who disposed of it.
