What maintenance is (and is not)
Maintenance is court-ordered support from one spouse to the other after separation or divorce. It is separate from child support (see Mont. Code Ann. § 40-4-204; Montana Child Support Guidelines) and from property division. A single judgment may include all three, but each has its own legal tests.
No spouse is automatically entitled to maintenance. Courts typically ask whether one party has a genuine need and whether the other has the ability to pay, then apply Montana's statutory framework.
Eligibility and statutory factors
Discretionary after eligibility findings. Courts apply statutory factors without a percentage formula.
Fault. Marital misconduct is generally not considered except as it relates to economic matters.
Document income, earning capacity, health, length of marriage, contributions as homemaker or to the other spouse's career, and the marital standard of living. Those facts drive both temporary (pendente lite) and final awards.
Types of maintenance in Montana
Temporary and longer-term maintenance; rehabilitative structuring is common.
Labeling matters. Rehabilitative awards usually require a plan (schooling, retraining, re-entry to the workforce). Durational or term awards run for a fixed period. Lump-sum or reimbursement awards may be non-modifiable depending on the judgment language and statute.
How amount is set
Montana does not use a statewide calculator for final maintenance. Judges weigh the statutory factors and the record. Online “alimony calculators” are at best rough illustrations and are not controlling.
Temporary support while a divorce is pending often follows different local practices or guidelines than the final award. Confirm what your county or division actually uses.
How long maintenance lasts
Duration should reflect the time needed to obtain education or employment unless longer support is justified.
Permanent / indefinite support. Limited. Indefinite awards are uncommon and fact-intensive.
When maintenance ends or can be changed
Death, remarriage, or the end of the ordered term.
Either party may usually seek modification upon a substantial change in circumstances unless the award was expressly made non-modifiable. Retirement, disability, remarriage, cohabitation, and large income swings are frequent triggers — but the statutory test and burden of proof are Montana-specific.
Taxes
Post-2018 federal TCJA rules apply; confirm Montana state-tax conformity.
Child support remains non-deductible and non-taxable. Do not assume maintenance treatment mirrors child support.
