Your decree of dissolution says which of you pays each debt. Your creditors never agreed to that. If both names are on a loan or card, the lender can still look to both of you, whatever the judge ordered. So the work after a divorce is to get every joint account paid off, refinanced, or closed, and to watch your credit reports until that is done. This article explains how. It is part of our Montana Divorce Guide.
Why the Decree Does Not Bind Creditors
A Montana court divides the marital estate between the two spouses, and in doing so considers each party's liabilities (MCA § 40-4-202(1)). The lender is not a party to that case. Its rights come from the contract you both signed.
The federal Consumer Financial Protection Bureau describes the result plainly: "Divorce changes the relationship between spouses, but it doesn't automatically change their relationship with creditors." A decree may allocate a debt to one spouse, but a creditor can still collect from anyone whose name appears as a borrower. The Bureau adds that you are generally responsible for a debt unless you were contractually released by the creditor or your former spouse refinanced the loan and removed your name, and that "sending creditors a copy of your divorce decree doesn't end your responsibility on a joint account."
How debts are assigned in the first place is covered in dividing debt in a divorce.
Account by Account
| Type of account | Who is responsible to the creditor | Usual way to separate it |
|---|---|---|
| Joint credit card | Both account holders are responsible to the card issuer for the balance. | Pay it off or have the responsible spouse move the balance to a card in one name, then close the joint account. |
| Card where you were only an authorized user | CFPB guidance says an authorized user is generally not responsible for the amount owed. | Ask the issuer to remove you as an authorized user. |
| Card in your name with your ex as authorized user | You remain responsible for charges on your account. | Remove the authorized user and request new card numbers. |
| Joint auto loan | Both borrowers remain liable until the loan is paid or refinanced. | Refinance into one name. Update the title and insurance to match. |
| Joint mortgage | Both borrowers remain liable. A deed does not change that. | Refinance, an approved assumption, a lender release, or sale. |
| Joint checking or savings | Ask the bank what each holder can do with the funds under the account agreement. | Divide the balance as the decree directs and close the account once automatic payments are moved. |
The distinction between a joint account holder and an authorized user matters. The Bureau's guidance is that you are responsible for the debt on a joint credit card account, but if you were only an authorized user on your former spouse's account, you are generally not responsible for the amount owed. If you are not sure which you were, ask the card issuer.
A creditor does not have to release a borrower just because the decree assigned the debt to the other one. Whether it will depends on the remaining borrower's income and credit. For the house, see transferring the house and refinancing.
Timing: During the Case and After the Decree
While the divorce is pending, do not start closing things. The automatic economic restraining order that the clerk issues with the summons restrains both parties from "canceling jointly held credit cards or terminating signatory authority of the other party on a credit card" and from "incurring unreasonable debt" (MCA § 40-4-126). It also restrains transferring or disposing of marital property without the other party's written consent or a court order, with exceptions for necessary living expenses, ordinary business operations, and reasonable professional fees.
Those restrictions protect both of you while the estate is being sorted out. Changes during the case should be made by written agreement or court order. Once the decree is entered, carry out what it says about each account, by the dates it sets. If the decree has no dates, sooner is better, because every month a joint account stays open is a month the other person's payment habits can affect you.
A Short Clean-Up List
- List every account that has, or ever had, both names on it. Your credit reports are the best source.
- For each one, confirm in writing with the creditor whether you are a joint holder, the sole holder, or an authorized user.
- Carry out the decree: pay off, refinance, transfer balances, and close.
- Ask for written confirmation that each joint account is closed or that you have been released.
- Move automatic payments and deposits before closing bank accounts.
- Update utilities, phone plans, insurance, and subscriptions that bill a joint card.
- Keep the confirmations with your decree.
Monitoring Your Credit Reports
The Federal Trade Commission explains that the three nationwide credit bureaus, Equifax, Experian, and TransUnion, let you check your credit report from each once a week for free at AnnualCreditReport.com. That is the only website authorized to fill those orders. You can also request reports by calling 1-877-322-8228.
Look for accounts you forgot, accounts that should show as closed and do not, late payments on debts assigned to your former spouse, and anything you do not recognize. If you find mistakes, the FTC says to contact the credit bureau and the business that supplied the information. If you see signs that someone opened credit in your name without permission, the FTC directs people to IdentityTheft.gov to report it and get a recovery plan.

If Your Ex Does Not Pay a Debt Assigned to Them
You may face a hard choice between paying a debt that is not yours under the decree and letting it go late on your credit. Whichever you choose, your claim is against your former spouse. Terms of a settlement agreement set out in the decree "are enforceable by all remedies available for enforcement of a judgment, including contempt, and are enforceable as contract terms" (MCA § 40-4-201(5)).
A settlement agreement may include a promise by each spouse to hold the other harmless on the debts they take. If yours does, that is the term you would ask the court to enforce, along with reimbursement of what you had to pay. Keep proof of every payment you make on the other person's debt. See enforcing a divorce decree.
Two related problems have their own rules. A joint tax return from a year before the divorce carries joint liability to the IRS regardless of what the decree says. See taxes the year you divorce. And if either of you is considering bankruptcy, see a bankruptcy lawyer.
