Mo. Rev. Stat. § 475.280: Settlement and report dockets — notice to conservators and guardians.

1. The clerk shall keep a docket in which shall be entered the names of all conservators and the particular day upon which their annual settlements are required.

2. The clerk shall notify each conservator by ordinary mail of the day on which each of his annual settlements is required to be filed at least thirty days before such date. Failure to receive the notice herein required does not excuse a conservator from making settlement as required by law.

3. Sections 473.560 to 473.567 as to decedents' estates apply to conservators and their settlements.

4. The clerk shall also keep a docket in which shall be entered the names of all guardians and limited guardians and the particular day upon which their report of annual personal review is required. The clerk shall notify such guardians in the same manner as prescribed in subsection 2 of this section. Failure to receive the notice herein required does not excuse such guardians from making the report as required by law.
