Executor's dutiesWithin 30 days after letters are granted (unless the court allows more time), the personal representative must file an inventory and appraisement of all the decedent's property, classified by type, with any liens. Notice of letters is published so creditors can file claims, which are barred unless filed within six months after first publication. The representative must file a statement of accounts for settlement every year on the anniversary of letters until administration is complete, and must file a final settlement on the first court day after six months and ten days from first publication of notice of letters, or as soon after as administration is completed.

Letters testamentaryEstates are opened in the probate division of the circuit court. 'Letters testamentary' are granted to the personal representative named in the will; if none qualifies, to another qualified person. Without a will, 'letters of administration' go first to the surviving spouse, then to one or more of those entitled to distribution whom the court believes will best manage the estate; a person with priority may nominate someone else. A nonresident may be appointed.
Disqualifications and bond rules: RSMo §§ 473.117, 473.160.

Most claims are barred 1 year after death whether or not an estate is opened.
