Montana Divorce Checklist: Every Document You Need to File

The Clerk of District Court will reject your dissolution filing for a blank field, a missing signature, or the wrong number of copies. Pro se filers in Montana lose weeks to these administrative bouncebacks — not because the law is against them, but because nobody gave them a complete list of what goes in the packet before they drove to the courthouse.

Here is that list, organized by filing phase.

Phase 1: The Initial Filing Packet

These documents organize the day-one packet. File the court-filed forms with the Clerk of Court and keep the MP-510 for service on your spouse only. Bring the original plus two copies of the filed forms unless your county specifies otherwise.

Without minor children (MP-112 packet):

• Petition for Dissolution of Marriage (MP-112) — signed and verified under oath
• Summons and Automatic Economic Restraining Order (MP-400) — the clerk issues this after you file the petition
• Proposed Property Distribution (MP-500) — your proposed division of all assets and debts
• Preliminary Disclosure of Income and Expenses (MP-510) — served on your spouse only, never filed with the court
• Statement of Inability to Pay (if requesting a fee waiver) — must be approved by a judge before the clerk assigns a case number

With minor children (MP-113 packet):

• Everything above, but use MP-113 instead of MP-112
• Proposed Parenting Plan (MP-300 series) — mandatory, covering physical custody, decision-making, holiday schedule, and relocation provisions
• Child support calculation worksheet
• Medical insurance disclosure for each child

Joint petition filers use MP-115 (no children) or MP-116 (with children) instead of MP-112/113. Both spouses sign as co-petitioners, and formal service of process is bypassed entirely.

Phase 2: Service of Process Documents

After filing, you must serve the respondent. The documents needed depend on your service method:

Mail acknowledgment method:

• Notice and Request for Acknowledgment of Service (MP-403.1) — two copies
• Prepaid return envelope addressed to you
• Complete copy of all filed documents

Sheriff service:

• Request for Sheriff to Serve Documents (MP-401)
• Complete copy of all filed documents plus the service fee (typically ~$50)

Private process server:

• Use a state-licensed professional process server and confirm the server's required documents and fee

Service by publication (last resort):

• Request for Order Granting Service of Summons by Publication (MP-402.1)
• Affidavit of Due Diligence detailing all search efforts
• Judge's signed order authorizing publication

Phase 3: Proof of Service

Once service is completed, file the original summons and executed proof with the court within 30 days of receiving the proof:

• Acknowledgment of Receipt of Service (MP-403.2 or MP-414) — if served by mail
• Sheriff's Return of Service — if served by sheriff
• Proof of Publication — if served by publication
• Original summons returned to the court

Phase 4: The Response (Respondent Only)

If you received papers, file within 21 calendar days of service:

• Response to Petition for Dissolution (MP-201) — signed and verified
• Your own Proposed Property Distribution (MP-500)
• Your own Preliminary Disclosure of Income and Expenses (MP-510) — served on petitioner, not filed
• Your own Proposed Parenting Plan (if children are involved)
• Filing fee of $70 ($60 appearance + $10 technology) or an approved fee waiver

Phase 5: Finalization Documents

Once all terms are agreed upon or adjudicated:

• Request for Hearing (MP-701), or MP-726 for clerk entry of default when applicable — or Joint Affidavit for Entry of Decree Without Hearing (if both parties agree to skip the hearing)
• Decree of Dissolution (MP-713 for no children, MP-703 for children with parenting plan)
• Notice of Entry of Decree (MP-704) — filed with the clerk and served on the other party, starting the 30-day appeal window
• Judgment fee of $50

Financial Documents to Gather Before You Start

Beyond the court forms, you will need these supporting records to complete your property distribution and financial disclosures accurately:

• Tax returns for the past 2-3 years
• Pay stubs for the past 3 months (both spouses)
• Bank and investment account statements
• Mortgage and loan statements
• Credit card statements showing current balances
• Retirement account statements (401(k), IRA, pension)
• Vehicle titles and registration
• Real estate appraisals or comparable sales data
• Insurance policy declarations pages (life, health, auto, home)
• Business financial statements (if either spouse owns a business)

Common Rejection Triggers

Clerks reject filings most often for:

• Blank fields that should read "N/A" or "None"
• Missing signatures or unsigned verification pages
• Using outdated form versions (check courts.mt.gov/forms for current versions)
• Wrong number of copies
• Filing the MP-510 with the court instead of serving it only on the spouse
• Missing parenting plan in cases with minor children
