Legal Separation in Minnesota

Last reviewed November 3, 2026

A legal separation in Minnesota is a court proceeding that settles spouses’ rights and responsibilities toward each other while leaving the marriage itself in place. The governing definition appears in Minn. Stat. § 518.06, subd. 1. A decree of legal separation resolves the same financial and parenting issues as a divorce. However, it does not end the marital status of either spouse. This page explains how a legal separation is obtained, what it decides, and how its legal consequences differ from those of a dissolution. It is part of the site’s guide to divorce in Minnesota.

Legal Separation and Dissolution Compared

Minnesota law describes the two proceedings in parallel terms. A dissolution “completely terminates the marital status of both parties.” A legal separation, by contrast, is a court determination of the spouses’ rights and responsibilities arising out of the marriage, and it “does not terminate the marital status of the parties” (§ 518.06, subd. 1).

Feature	Legal separation	Dissolution (divorce)
Marriage ends	No	Yes
Required finding	One or both parties need a legal separation	Irretrievable breakdown of the marriage
180-day residency requirement	Not required by § 518.07	Required (§ 518.07)
Property, debts, custody, support, maintenance	Decided by the court	Decided by the court
Either spouse may remarry	No	Yes
Surviving-spouse status at death	Generally retained	Ends

Grounds and the Uncontested Rule

A court grants a decree of legal separation when it finds that one or both parties need one (§ 518.06, subd. 1). Fault is not required. Indeed, traditional defenses such as condonation and recrimination have been abolished for both proceedings.

The statute adds a specific rule for agreed cases. When one or both spouses petition for legal separation, and neither contests it nor asks for a dissolution, the court must grant the separation (§ 518.06, subd. 3). If one spouse instead seeks a dissolution, the court evaluates that request under the irretrievable-breakdown standard. Consequently, one spouse generally cannot insist on a separation over the other’s request for a divorce once that standard is met. The site’s page on family law terms distinguishes legal separation from a simple physical separation.

Residency

A dissolution requires that one spouse have resided in Minnesota, or been domiciled or stationed here in the armed services, for at least 180 days before filing (§ 518.07, subd. 1). That requirement is written for dissolutions. As a result, spouses who have recently moved to Minnesota sometimes begin with a legal separation. Even so, the court must still have jurisdiction over the parties, the property, and any custody questions. Custody jurisdiction is governed separately by Minn. Stat. ch. 518D.

What a Separation Decree Decides

A legal separation proceeding addresses the same issues as a divorce:

• Property and debts, divided under Minn. Stat. § 518.58;
• Spousal maintenance, under § 518.552;
• Custody and parenting time, under the best-interests factors in § 518.17; and
• Child support, under the guidelines in chapter 518A.

The process is also similar. It includes a summons and petition, financial disclosure, and, in most contested cases, alternative dispute resolution under Minn. Gen. R. Prac. 310. The court costs are the same as well; see divorce filing fees and court costs. A legal separation is therefore rarely faster or less expensive than a divorce.

Property Acquired After the Decree

Marital property is defined by reference to the valuation date in the separation or dissolution proceeding (Minn. Stat. § 518.003, subd. 3b). Property a spouse acquires after that date is nonmarital. Thus, once the separation decree divides the estate, later earnings and acquisitions generally belong to the spouse who acquires them.

Consequences of Remaining Married

Remarriage

Because the marriage continues, neither spouse may remarry. Doing so requires a dissolution first.

Inheritance Rights

Under Minnesota’s probate code, a decree of separation that does not end the marital status is not a dissolution (Minn. Stat. § 524.2-802). A legally separated spouse may therefore still be treated as a surviving spouse when the other spouse dies. Spouses who do not intend that result should address estate rights expressly, both in the decree and in their wills and beneficiary designations.

Insurance and Benefits

Some spouses choose legal separation to preserve health insurance or other benefits tied to marriage. Eligibility, however, is controlled by each plan’s own terms, and many plans treat a legal separation like a divorce. The specific plan documents should be reviewed before relying on continued coverage.

Moving from Separation to Divorce

A separation decree does not convert automatically into a divorce. A spouse who later wants to end the marriage must bring a dissolution proceeding. In that proceeding, the court must find an irretrievable breakdown, and the residency requirement then applies. The earlier decree’s terms are often carried forward, but the new case can involve further negotiation. For this reason, spouses who expect eventually to divorce often proceed directly with a dissolution.

When a Legal Separation May Fit

A legal separation may suit spouses who:

• have religious or personal objections to divorce;
• wish to keep a specific benefit that their plan continues for separated spouses;
• want a binding order on finances and parenting while they consider reconciliation; or
• have not yet met the residency requirement for a dissolution.

Spouses who reach a full agreement may also document it in a court-approved stipulation. Unlike a postnuptial agreement, which governs a continuing marriage, a separation decree is a court judgment and is enforceable as one.
