In general, when someone dies, the estate must go through probate which can be a complicated and lengthy process. But many states provide less complicated options for smaller estates.

Missouri law provides for simplified probate when the value of the entire estate less liens, debt, and encumbrances does not exceed $40,000.  If no application for letters of administration has been filed or such application has been revoked, the personal representative or any distributee of the decedent may file a an affidavit with the court after a waiting period of 30 days.  The representative must also file a bond for at least the value of the personal property in the estate which must be approved by the judge or clerk of the probate court.
