You protect your finances in a Montana divorce by knowing what exists, keeping records, continuing to pay ordinary bills, and using the court when something is wrong. You do not protect them by moving money where your spouse cannot find it. Montana law restrains that, requires both spouses to disclose everything under oath, and lets the court account for value that was wasted or hidden. This page explains what you may and may not do, and it is part of our Montana Divorce Guide.
The Automatic Economic Restraining Order
When a petition for dissolution, legal separation, or declaration of invalidity is filed, the clerk of district court issues a summons and includes an automatic economic restraining order with it (MCA § 40-4-126(1)). The person who files acknowledges in the petition that the order applies to them on filing (MCA § 40-4-105(1)(h)). It binds the other spouse when the petition is served.
The order stays in place until the case is dismissed or a final order is entered, unless the court orders otherwise (MCA § 40-4-126(2)). The court may expand, limit, modify, or revoke it, and the spouses may waive some or all of its provisions by a joint written agreement. The table summarizes the main terms. The right-hand column gives the paragraph of the order as it is set out in § 40-4-126(1).
| Action | Status | Order ¶ |

| Pay ordinary living expenses: food, clothing, shelter, necessary health care, transportation to work, child care | Allowed | (1)(a) |
| Run an existing business in its customary and usual course | Allowed | (1)(b) |
| Pay a reasonable amount for professional fees and costs of the case | Allowed | (1)(c) |
| Create, modify, or revoke a will; change a power of attorney; create an unfunded trust | Allowed unless the court orders otherwise | (4) |
| Transfer, encumber, conceal, or dispose of marital property | Restrained without written consent or a court order | (1) |
| Cancel a joint credit card or remove your spouse as a signer | Restrained | (3)(a) |
| Take on unreasonable debt, including borrowing against a credit line secured by the home | Restrained | (3)(b) |
| Withdraw or borrow from retirement plans or IRAs | Restrained, except as the exceptions or the notice procedure allow | (3)(c) |
| Change a beneficiary on life insurance or on any other account or asset | Restrained | (3)(e) |
| Cancel, alter, or let lapse property, life, auto, or health insurance | Restrained | (3)(f) |

Before a Case Is Filed
The order does not exist until a petition is filed, but that is not a free period. The order itself says that in issuing temporary orders or a final decree, the court may consider any action taken by the petitioner within a reasonable time before filing that would have violated the order if it had been in place (MCA § 40-4-126(1)). And for either spouse, the property statute directs the court to consider "the contribution or dissipation of value of the respective estates" (MCA § 40-4-202(1)).
The practical rule is the same before and after filing: spend as you normally would, do not make unusual transfers, and keep a record of anything out of the ordinary and the reason for it.
Your Own Account and New Income
People are often told to open a separate account. Nothing in the order prohibits that, and having your pay deposited to an account in your own name can make budgeting for a second household simpler. Two cautions apply.
- A new account is not a separate estate. The court apportions property belonging to either or both spouses, "however and whenever acquired," whoever holds title (MCA § 40-4-202(1)). Income you earn before the decree and the account that holds it are part of what the court looks at.
- It must be disclosed. The preliminary declaration must identify all assets in which you have or may have an interest (MCA § 40-4-252(3)).
If your household has run on one joint account, do not redirect income in a way that leaves your spouse or children without money for necessities. If you cannot agree on how bills are paid, either spouse may ask for temporary maintenance, temporary child support, or a temporary family support order that assigns who pays which marital bills (MCA § 40-4-121(1)). See temporary orders during divorce.
Large or Unusual Transactions
For anything outside the ordinary, the order sets out a notice procedure. Each spouse must file a notice with the court of any proposed extraordinary expenditure, proposed revocation of a nonprobate transfer, or proposed elimination of a right of survivorship at least 14 days before acting. The notice must say what is proposed and when, how it may affect the marital estate, and why it is necessary at that time. If the other spouse files an objection within the 14 days, the action may not be taken until the court rules, and the spouse proposing it carries the burden of justifying it.
The simpler route, where it is available, is written consent. The order allows transfers made with the written consent of the other spouse.
Credit and Joint Debt
You may not cancel joint cards or take on unreasonable new debt, and neither may your spouse. What you can do is watch. Review statements for joint accounts as they arrive, keep copies, and check your credit reports so you know every account that carries your name. A divorce decree divides debts between spouses, but a creditor's rights come from the original contract, which is why joint debt deserves attention early. See dividing debt in a divorce and credit and joint accounts after divorce.
If Your Spouse Is Not Following the Rules
Do not answer one violation with another. If a spouse fails to comply with the order, the other may move the court for an appropriate order, including sanctions and all remedies for contempt (MCA § 40-4-126(4)). Either spouse may also ask for a temporary injunction restricting or reaffirming the order's terms (MCA § 40-4-121(2)(a)).
Disclosure has its own enforcement. An asset left off a final declaration is presumed to be grounds to award it to the other spouse (MCA § 40-4-253(4)). See hidden assets and dissipation.
Financial control can be part of an abusive relationship. If you are in danger, call 911. The National Domestic Violence Hotline is 1-800-799-7233, and our Montana Domestic Violence Guide explains orders of protection, which can include their own property restraints.
