Key Takeaways: Should I Move Out of the House During a Divorce?

Moving out does not forfeit your interest in the home. The court apportions property belonging to either or both spouses, whoever holds title, and who is living there is not a listed factor (MCA § 40-4-202(1)).
Montana abolished the old fault defenses, and property is divided without regard to marital misconduct. Leaving is not treated as a wrong that costs you property.
If you have children, where they live after you move can shape an interim parenting plan, because courts consider continuity and stability of care (MCA § 40-4-212(1)(h)).
The restraining order's living-expense exception takes into account the added cost of a second household (MCA § 40-4-126(1)).
A court can exclude a spouse from the family home on a showing that physical or emotional harm would otherwise result (MCA § 40-4-121(2)(c)).
If you are in danger, leave and call 911. The National Domestic Violence Hotline is 1-800-799-7233.

Moving out of the family home does not cost you your share of it under Montana law. The court divides property based on a list of statutory factors, and who is sleeping in the house is not one of them. What moving out can change is the day-to-day pattern of parenting, the household budget, and how safe everyone is. Those are the real questions to weigh. This page is part of our Montana Divorce Guide.

Moving Out Does Not Forfeit Your Property Interest

In a dissolution, the court "without regard to marital misconduct" equitably 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)). The factors the court considers include the length of the marriage, each spouse's age, health, income, and needs, and each spouse's contributions, including as a homemaker. Occupancy at the time of the divorce is not on the list.

Many people worry about "abandonment." Montana's dissolution statutes do not use that concept. The only ground is that the marriage is irretrievably broken, and the old fault-based defenses were abolished (MCA § 40-4-105(4)). For how the home itself is handled, see who gets the house in a divorce.

How Moving Out Can Affect Parenting

This is where the decision has legal weight. Either parent may ask for an interim parenting plan while the case is pending, and the court decides it under the best interest standard (MCA § 40-4-213(1)). The factors include the child's adjustment to home, school, and community, and continuity and stability of care (MCA § 40-4-212(1)(d) and (h)).

If you move out and the children stay, the arrangement that develops over the following weeks becomes the practical starting point when a court looks at what has been working. That does not decide the final plan, and the statute does not say that the parent who stays is preferred. It does mean that a parent who leaves should keep up regular, substantial time with the children from the beginning and, where possible, agree on a written schedule before moving. See interim parenting plans.

Taking the children and leaving without the other parent's knowledge raises different problems. The best interest factors treat frequent and continuing contact with both parents as being in the child's interest unless the court determines, after a hearing, that contact with a parent would be detrimental (MCA § 40-4-212(1)(l)). The exception is safety, covered below.

The Money Side of Two Households

One income stream that supported one home now has to support two. Montana's automatic economic restraining order recognizes this. Its exception for expenses necessary to maintain the marital standard of living or for the necessities of life takes into consideration "additional living expenses arising out of a party obtaining a second household and current available income" (MCA § 40-4-126(1)). Paying a deposit and rent on a reasonable place to live fits that exception. For a proposed extraordinary expenditure, the order requires a notice filed with the court at least 14 days ahead. The statute does not define the term, so ask before making a large commitment such as buying another home.

If you cannot agree on who pays what, either spouse can ask for temporary maintenance, temporary child support, or a temporary family support order that assigns marital bills while the case is pending (MCA § 40-4-121(1)). See temporary orders during divorce. Do not stop paying the mortgage, insurance, or utilities on your own. The restraining order bars canceling or allowing to lapse existing property insurance, among other policies.

When Safety Is the Reason

If you or your children are in danger, leave and call 911. The National Domestic Violence Hotline is 1-800-799-7233. The considerations above about parenting patterns do not outweigh safety, and Montana law reflects that.

A court may issue a temporary injunction excluding a party from the family home on a showing that physical or emotional harm would otherwise result (MCA § 40-4-121(2)(c)).
A temporary order of protection may remove and exclude the respondent from the petitioner's residence "regardless of ownership of the residence" (MCA § 40-15-201(2)(e)).
The right to petition for this relief may not be denied because the person vacated the residence to avoid abuse (MCA § 40-4-123(4)).
When the petitioner has fled the parties' residence, notice of the new residence must be withheld except by court order for good cause (MCA § 40-4-121(9)).

Physical abuse or the threat of it by one parent against the other parent or the child is itself a best interest factor (MCA § 40-4-212(1)(f)). Our Montana Domestic Violence Guide and our page on orders of protection during a divorce explain the process.

Practical Steps Before You Move

Talk first if it is safe to. A short written agreement about the parenting schedule and the bills prevents most of the problems described here.
Copy records, do not strip the house. Take your personal belongings and copies of financial records. Leave joint property in place and make a list or photos of what is there.
Update your own mailing address. The restraining order allows a spouse to submit a change of their own individual mail or email address.
Keep paying what you have been paying until there is an agreement or an order.
Stay involved with the children on a regular schedule from the first week.

Whether to stay, go, or share the house for a time is a decision about your family, not a legal test you pass or fail. Our overview on preparing for divorce in Montana puts it alongside the other early decisions.

FAQ

Should I Move Out of the House During a Divorce? FAQ

Do I lose my rights to the house if I move out?

No. In a Montana dissolution the court equitably apportions the property and assets belonging to either or both spouses, however and whenever acquired, and whether title is in one name or both (MCA § 40-4-202(1)). Who is occupying the home is not one of the listed factors. Each spouse's interest is determined and made final in the decree (MCA § 40-4-202(3)).

Is moving out considered abandonment in Montana?

Montana's dissolution statutes do not use abandonment as a ground or a defense. The only ground is that the marriage is irretrievably broken, the old fault-based defenses are abolished (MCA § 40-4-105(4)), and property and maintenance are decided without regard to marital misconduct. Moving out can still have practical effects on parenting arrangements and finances.

Can I take the children with me when I move out?

Before any court order exists, no parenting plan assigns where the children live, and the statutes do not answer this with a simple yes or no. A move that cuts the children off from the other parent can lead to an urgent motion and can reflect on the parent who did it, because frequent and continuing contact with both parents is considered to be in a child's best interest unless the court finds otherwise (MCA § 40-4-212(1)(l)). If safety is the reason, get advice right away about protective orders.

Can my spouse make me leave?

Not without a court order. A court can issue a temporary injunction excluding a party from the family home on a showing that physical or emotional harm would otherwise result (MCA § 40-4-121(2)(c)), and an order of protection can remove a person from a residence regardless of who owns it (MCA § 40-15-201(2)(e)). Short of an order, spouses decide living arrangements between themselves.

Who pays the mortgage if I move out?

Moving out does not change who owes the lender. Between the spouses, a court can enter a temporary family support order directing one or both to pay marital liabilities out of certain income sources while the case is pending (MCA § 40-4-121(1)). Without an order or agreement, missed payments affect both spouses' credit and the property itself.
