Quick answer: Missouri requires that one spouse has been a resident, or a member of the armed services stationed in the state, for 90 days before the proceeding starts, and that 30 days have passed since the petition was filed. The only ground is that the marriage is irretrievably broken, with no separation period.
This Missouri divorce timeline calculator applies RSMo 452.305. Enter the date residence began, your planned filing date and the service date: it shows the earliest filing date, the earliest judgment and the respondent’s deadline to answer, nothing more. A real case usually takes longer, because the court must also make provision for custody, support, maintenance and property.

What does this divorce timeline calculator check?
The calculator adds 90 days to the date residence began and tells you whether your planned filing date is early; if it is, it uses the first valid filing date. It then adds 30 days to the filing date for the earliest judgment, and 30 days to the service date for the respondent’s answer. It cannot say how long the court will take. Support and parenting questions that arise during the case are covered by the Missouri alimony calculator and the Missouri parenting time calculator.
