- Common forms include: Temporary and modifiable or non-modifiable maintenance as authorized; rehabilitative terms are common.
- Duration framework: Duration is case-specific; limited-term maintenance is frequent after mid-length marriages.
- Permanent / indefinite support: Possible after long marriages with lasting disparity, but often styled as modifiable rather than truly permanent.

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 Mo. Rev. Stat. § 452.340; Missouri Supreme Court Form 14 Directions) 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 Missouri's statutory framework.
Eligibility and statutory factors
Discretionary after threshold findings. Courts weigh statutory factors including comparable earning capacity and duration of marriage—no formula.
Fault. Conduct during the marriage may be considered among the statutory factors.
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 Missouri
Temporary and modifiable or non-modifiable maintenance as authorized; rehabilitative terms are 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
Missouri 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 is case-specific; limited-term maintenance is frequent after mid-length marriages.
Permanent / indefinite support. Possible after long marriages with lasting disparity, but often styled as modifiable rather than truly permanent.
When maintenance ends or can be changed
Death, remarriage, or expiration of a fixed term; cohabitation may support modification.
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 Missouri-specific.
Taxes
TCJA federal treatment applies post-2018; Missouri generally conforms for state tax.
Child support remains non-deductible and non-taxable. Do not assume maintenance treatment mirrors child support.
