What is an Uncontested Divorce?
An uncontested divorce is one where both spouses agree on all issues, including property division, debt allocation, child custody, child support, and spousal support.

How to File an Uncontested Divorce in Montana
Reach Agreement with Your Spouse
Discuss and agree on property division, debts, custody, support, and any other issues before filing. Write down your agreement — Divorce.ai can help you create a formal settlement agreement.
Complete Your Forms
Fill out the 4 required forms for Montana. See the complete forms list.
File Your Petition
File the petition with your local court and pay the $250 filing fee. E-filing may be available in your county.
Serve Your Spouse
Even in an uncontested divorce, you must formally serve your spouse. In many cases, your spouse can sign a waiver of service to simplify this step.
Wait for the Mandatory Period
Montana has a 20-day waiting period. Under Mont. Code Ann. § 40-4-126, no decree of dissolution may be entered until at least 20 days after the respondent was served with the summons and petition. For joint petitions, the 20-day waiting period runs from the date the joint petition was filed.
Receive Your Final Decree
Once the waiting period ends and the court approves your agreement, you will receive your final decree of divorce. Some courts require a brief hearing; others approve by mail.

Common Mistakes in Uncontested Divorces
Not putting your agreement in writing
Verbal agreements are not enforceable. Always create a written settlement agreement filed with the court.
Forgetting about retirement accounts
401(k)s, pensions, and IRAs earned during marriage are marital property. Address them in your agreement even if one spouse doesn't claim them.
Incomplete financial disclosure
Montana requires financial disclosure within 30 days. Hiding assets can void your agreement.
Skipping proper service
Even if your spouse agrees, improper service can invalidate the entire case. Follow Montana's service rules carefully.
