Montana Maintenance Case Law Examples
Marriage of: Kelly and Camp (2025)
Montana Supreme Court, DA 24-0659 (2025)
This recent case reinforces that final maintenance decrees are difficult to overturn. The Montana Supreme Court affirmed that a party cannot set aside a final judgment years later based on procedural issues like the lack of final financial disclosures if they did not object at the time of trial. The court enforced the original support order and awarded attorney fees to the recipient spouse, emphasizing the finality of dissolution decrees and the obligation to comply with maintenance orders.
In re Marriage of Peterson (2002)
2002 MT 96, 309 Mont. 339, 46 P.3d 605
The Montana Supreme Court affirmed that the duration of the marriage is a significant factor in determining spousal support, with longer marriages typically warranting longer support periods. The court also clarified that cohabitation alone doesn't automatically terminate maintenance.
In re Marriage of Gochanour (2007)
2007 MT 138, 337 Mont. 346, 160 P.3d 537
The Montana Supreme Court clarified that a spouse's earning capacity, not just actual earnings, may be considered when determining spousal support obligations. The court also addressed professional license considerations in maintenance calculations.
In re Marriage of Smith (2005)
2005 MT 201, 328 Mont. 178, 119 P.3d 100
The Montana Supreme Court addressed retirement considerations in spousal support cases, ruling that retirement may constitute a substantial change in circumstances justifying modification of maintenance obligations.
In re Marriage of Herron (1996)
278 Mont. 245, 924 P.2d 1174
The Montana Supreme Court established that the primary purpose of spousal support is to provide support for a spouse who cannot be self-sufficient, not to punish the other spouse. The court emphasized that maintenance should be based on need and ability to pay.
Modifying Maintenance in Montana
Montana law allows for modification of maintenance under certain circumstances. Here's the process for requesting a modification:
Grounds for Modification
Under Montana Code Annotated § 40-4-208, maintenance can be modified for:
A substantial and continuing change in circumstances
Remarriage of the recipient spouse
Payor's retirement at a reasonable age
Recipient's improved earning capacity
Disability or health issues affecting earning capacity
Modification Process
File a Petition: Submit a Petition for Modification to the court that issued the original order.
Serve Notice: Legally notify the other party using certified mail or a process server.
Gather Evidence: Collect documentation supporting the change (tax returns, pay stubs, medical records).
Mediation: Many Montana courts require mediation before a hearing.
Court Hearing: If unresolved, present evidence to the court for a decision.
Important Considerations
Modifications are not retroactive - they only apply from the filing date forward.
Never stop paying maintenance without court approval - you risk contempt charges.
Montana requires a "substantial and continuing" change in circumstances.
Retirement modifications typically require the payer to be at least 65 years old.
Note: The modification process typically takes 3-6 months for uncontested cases and 9-18 months for contested cases, depending on court backlogs.
