St. Louis, Missouri Family Court Guide

St. Louis is an independent city in Missouri that runs its own court. How and where to file family court papers for St. Louis: the clerk of court, e-filing, filing fees, and self-help for custody, child support, and divorce.

The most time-sensitive thing for any St. Louis parent is the response clock. In Missouri you generally have 30 days to file a written response after you are served (Mo. Sup. Ct. R. 55.25(a)). 45 days after first publication if you were served only by publication. Miss that window and the other side can ask the St. Louis city court to move ahead without you, so put the deadline on your calendar the day you are served and confirm the exact date with the clerk.

Child support for St. Louis families is set under Missouri's Income Shares guideline. Both parents' incomes combined; obligation split proportionally by income share. The judge applies the same statewide formula whether you file in St. Louis or anywhere else in Missouri, so an honest income picture and the official worksheet matter more than where in the state you live.

When St. Louis parents split parenting time, Missouri courts call the schedule "Custody / Parenting Time", and that is the language to use in your paperwork. If safety is the issue, the order to ask the St. Louis city court about is the Order of Protection.
