Montana Divorce Myths and What the Law Actually Says

Several common beliefs about divorce do not match Montana law. Fault does not decide who gets what. Neither parent starts ahead because of their sex. Property is not automatically split in half, and a name on a title does not settle ownership. You do not have to be separated first, and alimony is not automatic. Each correction below comes from the text of the Montana Code Annotated. This page is part of our Montana Divorce Guide.

Myth: Fault Matters

Montana has one ground for dissolution: the marriage is irretrievably broken (MCA § 40-4-104(1)(b)). The defenses that existed under the old fault system, "including but not limited to condonation, connivance, collusion, recrimination, insanity, and lapse of time, are abolished" (MCA § 40-4-105(4)).

Fault is also excluded from the money. The court apportions property "without regard to marital misconduct" (MCA § 40-4-202(1)) and sets maintenance "without regard to marital misconduct" (MCA § 40-4-203(2)). Two things are different from marital misconduct and do matter. Wasting or hiding assets is financial conduct, and the court must consider "dissipation of value." And abuse matters in parenting, where physical abuse or the threat of it by one parent against the other parent or the child is a best interest factor (MCA § 40-4-212(1)(f)).

Myth: Mothers Always Get the Kids

Montana's parenting statutes are not written around awarding custody to a mother or a father. They are written around a parenting plan, determined "in accordance with the best interest of the child" (MCA § 40-4-212(1)). The listed factors include the wishes of the parents and the child, the child's relationships and adjustment to home, school, and community, the health of everyone involved, continuity and stability of care, and the child's developmental needs. A parent's sex is not on the list.

The statute also says that frequent and continuing contact with both parents is considered to be in the child's best interest, unless the court determines after a hearing that contact with a parent would be detrimental (MCA § 40-4-212(1)(l)). The listed factors direct the court to the child's relationships, stability, and needs, not to which parent is the mother or the father. See the best interest of the child factors.

Myth: Everything Is Split 50/50

This myth has two versions. For property, the statute requires the court to "equitably apportion" it after considering factors such as the duration of the marriage, each spouse's age, health, occupation, income, employability, liabilities, and needs, and the contribution of a spouse as a homemaker (MCA § 40-4-202(1)). Equitable means fair under those factors. Sometimes that is an equal division and sometimes it is not. See how property is divided in Montana.

For parenting time, the best interest statute does not set an equal schedule as a starting point. Parents can agree to one, and a court can order one when it serves the child. See is 50/50 parenting the default.

Myth: What Is in My Name Is Mine

The court apportions "the property and assets belonging to either or both, however and whenever acquired and whether the title to the property and assets is in the name of the husband or wife or both" (MCA § 40-4-202(1)). A retirement account in one spouse's name, a house deeded to one spouse, and a business one spouse runs are all before the court.

That does not mean origin is irrelevant. For property owned before the marriage, or received by gift or inheritance, the court must consider the other spouse's contributions, including the nonmonetary contribution of a homemaker and the extent to which those contributions facilitated the maintenance of the property. The same reach applies to disclosure: every asset must be listed, whatever name is on it (MCA § 40-4-252(3)). See separate versus marital property.

Myth: We Have to Be Separated for Six Months

The finding that a marriage is irretrievably broken must be supported by evidence of one of two things: that the spouses have lived separate and apart for more than 180 days before the case began, or that there is "serious marital discord that adversely affects the attitude of one or both of the parties towards the marriage" (MCA § 40-4-104(1)(b)). The word between them is "or." Spouses who still live in the same house can file.

The time rules that do apply are different ones: 90 days of Montana domicile or military presence before filing (MCA § 40-4-104(1)(a)), and no decree until 21 days after service (MCA § 40-4-105(3)). See do we have to be separated first.

Myth: Alimony Is Automatic

Montana calls alimony maintenance. A court may grant it only if it finds that the spouse seeking it lacks sufficient property to provide for their reasonable needs and is unable to be self-supporting through appropriate employment, or is the custodian of a child whose condition or circumstances make it appropriate that the custodian not be required to seek employment outside the home (MCA § 40-4-203(1)).

If that threshold is met, the amount and duration are what the court considers just after weighing the listed factors (MCA § 40-4-203(2)). The statute contains no formula and no rule tied to a number of years of marriage. It is also available to either spouse. See who qualifies for maintenance.

Myth: My Spouse Can Refuse the Divorce

If one spouse states under oath that the marriage is irretrievably broken and the other denies it, the court does not dismiss the case. It considers all relevant factors, including the prospect of reconciliation, and either makes a finding or continues the matter for a further hearing 30 to 60 days later, when it makes the finding (MCA § 40-4-107(2)). A spouse who does not respond at all does not stop the case either. See can my spouse refuse a divorce.
