Minimum period or timing rule
Separation for more than 180 days is one way to establish the breakdown of the marriage; serious marital discord may be an alternative. Do not therefore assume that 180 days of separation is required in every case.

PREPARATION ROADMAP
Use this order before filing.
- 01
Confirm residence and filing eligibility
For an ordinary Montana dissolution, one spouse must have maintained Montana domicile or qualifying military presence for 90 days before filing. Separately, §25-2-118(3) places the case in a county where the petitioner or respondent resided during the 90 days before filing. Child-custody jurisdiction and exceptions require separate review. Record actual dates and do not combine two people’s residence periods unless the controlling rule expressly allows it.
- 02
Identify the correct court and county
Use the official statewide source to locate the trial court or clerk. Confirm venue, the family-law filing location, accepted filing method, current fee and required local packet.
- 03
Select the procedure that matches the facts
Check whether the state distinguishes regular, joint, simplified, summary, contested or uncontested procedures. Agreement alone does not prove eligibility for a shorter procedure.
- 04
Collect the facts requested by the forms
Prepare legal names, marriage and separation dates, residence history, children’s information, income, expenses, assets, debts, requested relief and existing orders.
- 05
Prepare opening documents without inventing events
Complete only facts you know. Leave clerk, court, signature, notarization, service and later-event fields for the correct person and stage.
- 06
File and complete valid notice
A draft or download is not a filed case. Follow the clerk’s instructions and record service or waiver only after the legally effective event occurs.
- 07
Address disclosure, children and unresolved issues
Use current financial, child-jurisdiction, parenting and support documents. Settlement terms should match the procedure and be reviewed before rights are waived.
- 08
Obtain and review the final judgment
A waiting or separation period does not itself end a marriage. Confirm entry and the effective date from the court’s signed or entered order.
RESIDENCE CHECK
Which spouse has maintained Montana domicile or qualifying military presence for 90 days immediately before filing?
Generally, one spouse must satisfy the requirement of Montana domicile or qualifying military assignment for 90 days before filing.
This intake question helps organize facts; it does not decide domicile, jurisdiction or venue for an individual case.
