MO sets alimony by judicial discretion; there is no statutory formula. Courts weigh the enumerated factors below.
Factors the court weighs
- Seeking spouse’s resources, apportioned property, needs, and child-custodian support
- Time needed for education or training
- Comparative earning capacity
- Marital standard of living
- Each party’s obligations, marital property, and separate property
- Marriage duration
- Seeking spouse’s age and physical and emotional condition
- Paying spouse’s ability to meet both parties’ needs
- Conduct during the marriage
- Any other relevant factor
Mo. Rev. Stat. § 452.335.2
Duration limits
- Threshold findings: Maintenance is available only after findings that the seeking spouse lacks sufficient property for reasonable needs and cannot self-support through appropriate employment, or appropriately remains home as a child’s custodian.
- Term and modification: The court sets a just amount and period and states whether the order is modifiable or nonmodifiable; a dated modifiable order may be changed for a substantial and continuing change before termination.
Assumptions
- This tool does not estimate a dollar amount for discretionary states: any number would be invented.
- Missouri supplies threshold findings and ten factors, not a mandatory statewide dollar formula.
Estimate only. The court or state agency calculation controls.
Missouri alimony under Mo. Rev. Stat. § 452.335.
Maintenance starts with two required findings
The seeking spouse must lack sufficient property for reasonable needs and be unable to self-support through appropriate employment, subject to the child-custodian circumstance.
Only then does the court select a just amount and period after considering ten statutory factors.
Do not skip eligibility
Document reasonable needs, apportioned property, employability, and any child-care circumstance before moving to amount and duration.
What this estimate includes
- Eligibility test
- Ten-factor checklist
- Modification framework
What it leaves out
