Missouri's courts
| Court | Role |

| Trial courts | Circuit courts |
Before you start
Missouri adopted pure comparative fault by judicial decision in Gustafson v. Benda (1983). The Court of Appeals also disposes of many cases by unpublished order under Rule 84.16(b); those orders aren't precedent.
Fault and recovery
Missouri applies pure comparative fault: a plaintiff's recovery is reduced by their share of fault, even if they were mostly at fault.

From facts to cases
Suppose a client tells you: "A St. Louis delivery van ran a red light and hit our client's car; the van's company says our client was speeding." The closest Missouri decisions on facts like these will tell you more than a keyword search; read them alongside the comparative fault rule from Gustafson v. Benda and later Missouri decisions.
LegiMatch ranks real decisions by how closely their facts, issues and statutes match yours - up to 100 per matter - so the most useful cases are at the top. Results link to the courts' text, and the tool doesn't give legal advice.
