Spousal support in Missouri is determined by a statutory multi-factor analysis under RSMo § 452.335. The court weighs the following factors to arrive at a fair support amount and duration. Unlike the temporary formula, there is no mathematical calculation for permanent support — it is a discretionary determination by the judge based on the totality of the circumstances.
The types of spousal support available in Missouri include: Rehabilitative (fixed term), Indefinite (long-term). The type ordered depends on the length of the marriage, each spouse's financial situation, and the supported spouse's ability to become self-supporting.
Primary statute: RSMo § 452.335
The court considers these 8 statutory factors when determining the amount and duration of spousal support:
Financial resources of the party seeking maintenance, including marital property apportioned
Time necessary to acquire education or training for appropriate employment
Comparative earning capacity of each spouse
Standard of living established during the marriage
Obligations and assets of each party
Duration of the marriage
Age and physical and emotional condition of the seeking spouse
Ability of the paying spouse to meet own needs while paying maintenance
No formula. Both rehabilitative and indefinite maintenance available. Entirely discretionary based on 8 factors.
Duration is one of the most heavily litigated aspects of spousal support. The length of the marriage is the single most important factor in most cases, but the court also considers the supported spouse's age, health, job skills, and the time needed to acquire education or training for appropriate employment.
Two-part eligibility test: (1) insufficient property or cannot self-support, AND (2) other spouse has ability to pay.
Conduct during marriage IS a factor for BOTH property and maintenance.
Unique commingling rule: intent of the owner determines whether separate property was converted to marital (RSMo §452.330(4)).
