You can file for divorce, or be served with one, while a partner or family member assault (PFMA) charge is pending. Montana dissolution is no-fault, so the charge does not decide whether the marriage ends or how property is divided. It does bear on the parenting plan, and anything you put in a sworn family court filing can be read by the prosecutor. This page covers how the two cases interact. It is part of our Montana Domestic Violence Guide.

Montana Divorce Is No-Fault

A district court enters a decree of dissolution when three things are shown (MCA § 40-4-104(1)):

  • one party was domiciled in Montana, or stationed here as a member of the armed services, for 90 days before the action was filed;
  • the marriage is irretrievably broken, supported by evidence that the parties have lived separate and apart for more than 180 days before filing, or that there is serious marital discord that adversely affects the attitude of one or both parties toward the marriage; and
  • the court has addressed parenting, child support, maintenance, and property to the extent it has jurisdiction.

Older fault defenses, including condonation, collusion, and recrimination, are abolished (MCA § 40-4-105(4)). Neither spouse has to prove the other did something wrong.

Where the Allegation Does and Does Not Matter

IssueDoes alleged abuse matter?MCA
Granting the dissolutionNo. The question is whether the marriage is irretrievably broken.40-4-104(1)(b)
Dividing propertyThe court apportions property without regard to marital misconduct.40-4-202(1)
MaintenanceSet without regard to marital misconduct.40-4-203(2)
Child supportSet without regard to marital misconduct, using the state guidelines.40-4-204(1) and (3)
Parenting planYes. Physical abuse or threat of physical abuse is a listed factor.40-4-212(1)(f)
Temporary ordersYes. A party can be excluded from the family home on a showing that physical or emotional harm would otherwise result.40-4-121(2)(c)

The practical result is that the criminal allegation concentrates its effect on two parts of the divorce: the temporary orders at the start, and the parenting plan. See parenting plan factors and abuse.

Sworn Statements and the Criminal Case

A dissolution petition is verified, meaning sworn, and so is the response (MCA § 40-4-105(1) and (3)). Motions for temporary orders and interim parenting plans require affidavits setting out facts (MCA §§ 40-4-121(1) and 40-4-220(1)). In a contested case you may also be asked questions under oath.

Two rules make this matter for a pending charge. Rule 801(d)(2) of the Montana Rules of Evidence covers an "admission by party-opponent," which includes a statement offered against a party that is the party's own statement. And the Montana Constitution provides that "No person shall be compelled to testify against himself in a criminal proceeding" (Article II, section 25). How that protection is asserted in a civil case, and what it costs you there, is a judgment call that belongs to your lawyers, made question by question.

The safe practice is simple. Nothing that describes the incident, your relationship history, or your drinking or temper goes into the family file until your criminal defense lawyer has read it. That includes informal documents such as a parenting evaluation questionnaire or a letter to a guardian ad litem.

Deadlines Do Not Wait for the Criminal Case

If you are served, you may file a verified response within 21 days after the date of service (MCA § 40-4-105(3)). The dissolution statutes do not contain an automatic pause for a pending criminal charge. A court can be asked to adjust the schedule, and practice varies by judge, but you should assume every family court deadline is real.

Missing the response deadline can lead to orders entered without your input, including a parenting plan, because a final plan is incorporated into a decree even in a default (MCA § 40-4-234(1)).

The No Contact Order Still Applies

A divorce does not create an exception to a no contact order under MCA § 45-5-209 or to a release condition. You may not call your spouse to talk about settlement, the house, or the children unless an order specifically allows it. Consent of the protected person is not a defense.

Communication moves through lawyers and court filings. If you do not have a family lawyer, ask the court clerk how to serve documents without direct contact, and do not hand anything to your spouse yourself or through a relative unless the order allows that. Court hearings where both spouses appear should be raised with your criminal defense lawyer beforehand, so the no contact order can be addressed. Our page on what counts as contact explains the limits.

Money and the House From Day One

On filing, the clerk issues an automatic economic restraining order with the summons. It restrains both parties from transferring, encumbering, concealing, or disposing of marital property without written consent or a court order, with exceptions for the necessities of life and ordinary business, and from things like canceling insurance or changing beneficiaries (MCA § 40-4-126(1)). It binds the petitioner on filing and the respondent on service.

Either party may also ask for temporary maintenance, temporary child support, or a temporary family support order that assigns who pays which bills while the case is pending (MCA § 40-4-121(1)). We cover that in the family home and bills during the case.

Timing: File Now or Wait

There is no single right answer. Reasons people file while the criminal case is open include the need for a parenting schedule, support, or decisions about the home. Reasons to move carefully include the risk that sworn statements or testimony will be used in the criminal case, and the fact that the outcome of the charge may change the parenting analysis. A conviction for certain offenses gives the other parent a specific tool under MCA § 40-4-219(8).

These tradeoffs are why the criminal and family lawyers must talk to each other. See one lawyer for criminal and family cases, our divorce page, and PFMA and child custody.
