You don’t need a lawyer to get divorced in Montana — as long as your case is uncontested and both spouses agree on the terms. Here’s the complete process from start to finalized decree, with Montana-specific requirements throughout.

Is a Lawyer Required to Get Divorced in Montana?

No. Montana — like every US state — gives any person the right to represent themselves in court proceedings, including divorce. This is called “pro se” representation. Montana’s District Court processes self-represented divorce filings every day, and they are handled identically to attorney-filed cases.

You qualify for a lawyer-free divorce in Montana if:

Both spouses agree on how to divide all marital property and debt, any spousal support, and — if you have children — custody arrangements, parenting schedules, and child support amounts. You don’t need to agree on everything before starting, but you need full agreement before filing.

When you do need an attorney: If your spouse contests any major issue, there is a history of domestic violence, significant business interests require valuation, or you need temporary court orders while the divorce is pending — consult a licensed Montana family law attorney.

Montana Divorce Requirements

Residency Requirement

At least one spouse must have been a resident of Montana for a minimum of 90 days before filing. You do not need to have been married in Montana.

Grounds for Divorce

Montana allows divorce on the grounds of irretrievable breakdown only. For an uncontested no-fault divorce, no proof of wrongdoing is required.

Waiting Period

Once you file, Montana requires a 20 days waiting period before the divorce can be finalized. Montana is no-fault only. The 20-day waiting period begins after the petition is served.

Where to File

In Montana, file your divorce petition with the District Court in the county where either spouse resides. Filing instructions specific to your jurisdiction are included with the document service.

What You Need Before You Start

📋Both spouses’ full legal names, dates of birth, and current addresses
📋Date and location of marriage as listed on your marriage certificate
📋Date of separation — when you stopped living together as spouses
📋All marital assets — real property addresses, vehicle VINs, bank and retirement account summaries
📋All marital debts — mortgage, vehicle loans, credit cards, personal loans
📋Children’s information (if applicable) — names, dates of birth, current residence
📋Income information for both spouses — needed for support calculations
Tip: You don’t need every number before you start. The questionnaire saves your progress — stop, look something up, and return. Having a rough inventory ready speeds the process significantly.

Step-by-Step: How to File for Divorce in Montana Without a Lawyer

1
Confirm you meet Montana’s residency requirementVerify that at least one spouse has lived in Montana for 90 days. Courts can dismiss cases filed prematurely.
2
Reach agreement with your spouse on all major issuesDiscuss and document agreements on property division, debt, spousal support, and — if you have children — custody, parenting time, and support amounts. The more you resolve before the paperwork, the faster the process.
3
Complete the online divorce questionnaireOnlineDivorce.com’s guided questionnaire generates Montana-specific, court-ready forms based on your answers. Most couples complete it in 30–60 minutes. Both spouses can contribute. Progress saves automatically.
4
Review and download your completed Montana formsWithin 2 business days, completed documents are ready in your account. Review carefully — verify names, dates, and agreed terms. Revisions are available within your 30-day access window.
5
Sign the documents (with notarization if required)Most Montana divorce documents require both spouses’ signatures. Some forms require notarization — your filing instructions specify which. Noble Notary provides notarization throughout Florida; for other states, UPS Store, bank branches, and courthouse clerks commonly offer notary services.
6
File your petition at the District CourtBring completed forms to the District Court in the county where either spouse resides. Pay the filing fee ($170–$200). The clerk stamps your petition and assigns a case number. Keep copies of everything. Ask about income-based fee waivers if cost is a concern.
7
Serve the divorce papers on your spouseYour spouse must be formally served. For uncontested cases, many Montana courts allow your spouse to sign a voluntary acknowledgment of service. If not, a process server or sheriff can complete service for approximately $50–$150.
8
Wait out the 20 days waiting periodAfter filing and service, Montana requires a 20 days waiting period before the judge can sign your final decree.
9
Submit your final decree for judge’s signatureIn many uncontested Montana cases, no hearing is required — the judge reviews and signs based on submitted paperwork. Your filing instructions will clarify if a brief hearing is needed in your specific county.
10
Receive your signed divorce decreeOnce signed, your divorce is legally finalized. Obtain certified copies from the court clerk — you’ll need them to update IDs, financial accounts, and beneficiary designations. Order at least 3–4 certified copies at time of filing.

Frequently Asked Questions — Divorce in Montana Without a Lawyer

Can I really file for divorce in Montana without any legal training? ▼
Yes — thousands of Montana residents do it every year. The right to represent yourself in court is guaranteed in every US state. For uncontested cases, the process is procedural: completing and filing the correct forms correctly. The online service handles form preparation; you handle filing using the included step-by-step instructions.
What if my spouse won’t cooperate or sign the papers? ▼
A spouse’s refusal doesn’t prevent a divorce. If your spouse is served but doesn’t respond, you can request a default judgment from the District Court. If your spouse actively contests the terms, the divorce becomes contested and typically requires attorney involvement.
We have children. Can we still do this without a lawyer in Montana? ▼
Yes. Online divorce services handle cases with minor children at the same $199 flat fee — parenting plans, custody arrangements, child support calculations, and parenting schedules are all included. Both spouses must agree on all child-related terms.
How long will the process take in Montana? ▼
Document preparation takes 30–60 minutes plus 2 business days for delivery. The 20 days waiting period then begins after filing. Total timeline: typically 4–8 weeks from starting the questionnaire to receiving your final decree.
We own a house and have retirement accounts. Is that too complex? ▼
Not if you agree on the terms of division. Real estate, retirement accounts (including QDRO guidance), vehicles, and shared debt are all covered in the questionnaire at the same $199 price. Retirement accounts like 401(k)s will need a separate QDRO document after the divorce — typically $500–$2,500 from a QDRO specialist.
Can I get the Montana court filing fee waived? ▼
Montana courts have a fee waiver process for people who meet income guidelines. You apply at the courthouse clerk’s office when you file. If approved, you pay nothing. If denied, you pay the standard fee ($170–$200). The $199 document service fee is separate and not waivable through the court.

After Your Divorce Is Final: Important Next Steps

→Obtain certified copies of your final decree — needed for name changes, account updates, and beneficiary changes
→Update your Social Security card and driver’s license if resuming a former name
→Update beneficiary designations on life insurance, retirement accounts, and bank accounts
→Refinance any joint mortgage into one spouse’s name — only a refinance removes a spouse from mortgage liability
→Update your estate planning documents — will, power of attorney, and healthcare directive
→Initiate the QDRO process if any retirement accounts were divided in the settlement
