Missouri Spousal Maintenance Calculator

Under §452.335(1), the requesting spouse must prove: (1) they lack sufficient property — including marital property — to provide for their reasonable needs, and (2) they are unable to support themselves through appropriate employment, or are the custodian of a child whose age or condition makes outside employment inappropriate.

Under §452.335(2), courts consider: financial resources of the requesting spouse; time needed for education or training; comparative earning capacity; standard of living during the marriage; obligations and assets of each party; duration of the marriage; age and health; ability of the paying spouse to meet their own needs while paying maintenance; and the conduct of the parties during the marriage.

Yes. "The conduct of the parties during the marriage" is a listed factor under §452.335(2)(8). While Missouri is a no-fault divorce state, marital misconduct can influence the maintenance award — courts have discretion to weigh fault in setting the amount or duration.

Yes, unless the parties agree otherwise. Either party may petition to modify or terminate maintenance upon a showing of a substantial and continuing change in circumstances that makes the current terms unreasonable. Remarriage of the recipient terminates maintenance; death of either party also terminates it.
