Divorce When Your Spouse Lives in Another State

Yes, you can get a divorce in Montana when your spouse lives in another state, as long as you meet Montana's residency requirement yourself. The harder question is what else the court can do. A court's power to end a marriage and its power to order an absent person to pay money or give up property are two different things, and Montana's dissolution statute recognizes that. This page is part of our Montana Divorce Guide.

Ending the Marriage Takes Only One Montana Spouse

The court enters a decree of dissolution if "one of the parties" was domiciled in Montana, or stationed here in the armed services, for 90 days before filing, and the marriage is irretrievably broken (MCA § 40-4-104(1)(a) and (b)). The third requirement is worded carefully: the court must have considered or provided for parenting, child support, maintenance, and property "to the extent it has jurisdiction to do so" (§ 40-4-104(1)(c)).

That phrase reflects a long-standing rule of constitutional law sometimes called divisible divorce. In Estin v. Estin, 334 U.S. 541 (1948), the U.S. Supreme Court treated a divorce decree as effective to change marital status but ineffective on support, because the court that entered it had no personal jurisdiction over the absent spouse.

What Personal Jurisdiction Means

Personal jurisdiction is the court's authority over a particular person. Under Rule 4(b)(1) of the Montana Rules of Civil Procedure, everyone found within Montana is subject to the jurisdiction of Montana courts. A person outside the state is subject to it for claims arising from certain acts, including the ownership, use, or possession of property located in Montana. Rule 4(b)(2) adds that a court acquires jurisdiction through service of process as the rule provides or by the person's voluntary appearance, personally or through an attorney.

The federal Constitution sets the outer limit. In Kulko v. Superior Court, 436 U.S. 84 (1978), the Supreme Court held that California could not exercise personal jurisdiction in a child support case over a father who lived in New York. His agreeing that his daughter could live with her mother in California was not enough of a connection. A spouse who has never lived in Montana and has no ties here may be beyond the court's reach on money issues.

What the Court Needs for Each Issue

Whether your spouse's past connections to Montana are enough is a fact question. A couple who lived in Montana for years before one moved away is in a different position from a couple who never lived here together.

Serving a Spouse Outside Montana

When a person cannot with due diligence be served inside Montana, Rule 4(n) allows personal service outside the state in the same manner as inside, with the same force and effect. Service tells your spouse about the case and starts the 21-day response period in MCA § 40-4-105(3). It does not create personal jurisdiction where no ground for it exists.

If your spouse cannot be located, Rule 4(o)(1)(C) permits service by publication in an action for dissolution of the marriage of a Montana resident. The rule is direct about the limits: the court may then adjudicate the absent spouse's interest in "the status, property, or thing acted upon," but the decree "does not bind the defendant personally" unless some ground for personal jurisdiction exists (Rule 4(o)(2)).

Property and Maintenance Can Be Decided Later

Montana's statutes plan for the divided case. The property statute applies to a proceeding for "division of property following a decree of dissolution of marriage or legal separation by a court that lacked personal jurisdiction over the absent spouse or lacked jurisdiction to divide the property" (MCA § 40-4-202(1)). The maintenance statute has matching language (MCA § 40-4-203(1)). So a decree that ends the marriage without reaching those issues does not necessarily close the door on them. It may mean a second proceeding, here or in another state, once a court has authority over both spouses or the property.

Before you accept a status-only decree, consider what it changes. Health coverage as a spouse, the automatic economic restraining order in the Montana case, and survivorship rights can all be affected when the marriage ends, while the property questions remain open.

Children Follow Different Rules

Parenting jurisdiction does not depend on personal jurisdiction at all. Under the uniform act Montana has adopted, a Montana court can make an initial parenting determination if Montana is the child's home state when the case starts, or was within the prior 6 months and a parent still lives here, with fallback rules when no state qualifies (MCA § 40-7-201(1)). The statute says that physical presence of, or personal jurisdiction over, a party or a child is neither necessary nor sufficient (§ 40-7-201(3)). See which state decides custody.

Child support is the opposite. It is a money obligation, and the court needs personal jurisdiction over the parent who would pay. MCA § 40-5-1008(1) lists the bases for reaching a nonresident. One state may end up deciding parenting while support is established or enforced through another.

When Your Spouse Will Cooperate

Most of this analysis matters only when a spouse will not participate. A spouse who joins a joint petition, or files a response has appeared, and the court can then approve a full agreement on property, maintenance, and support. If you and your spouse are on workable terms, an uncontested divorce can be handled with documents signed in two states. If either of you plans to relocate while the case is open, read moving out of state during a divorce first.
