Mo. Rev. Stat. § 473.360
Limitations on filing of claims
473.360. Limitations on filing of claims — when claims barred. — 1. Except as provided in section 473.370, all claims against the estate of a deceased person, other than costs and expenses of administration, exempt property, family allowance, homestead allowance, claims of the United States and claims of any taxing authority within the United States, whether due or to become due, absolute or contingent, liquidated or unliquidated, founded on contract or otherwise, which are not filed in the probate division of the circuit court within six months after the date of the first published notice of letters testamentary or of administration or, if notice was actually mailed to, or served upon, such creditor, within two months after the date such notice was mailed, or served, whichever later occurs, or which are not paid by the personal representative, within six months after the first published notice of letters testamentary or of administration, are forever barred against the estate, the personal representative, the heirs, devisees and legatees of the decedent. No contingent claim based on any warranty made in connection with the conveyance of real estate is barred under this section. This six-month period does not extend any other applicable limitation periods.
2. Unless written notice of actions instituted or revived under section 473.363 or 473.367 is filed in the probate division within six months after the first published notice of letters, no recovery may be had in any such action on any judgment therein against the personal representative out of any assets being administered upon in the probate division or from any distributee or other person receiving the assets. Timely filing of the claim against the estate, under this section, within six months after the first published notice of letters, whether said claim is filed before or after the institution or revival of an action against the personal representative or the estate shall satisfy the requirement of written notice herein imposed.
3. Nothing in this section affects or prevents any action or proceeding to enforce any mortgage, pledge or other lien upon property of the estate; except that attachment, judgment, and execution liens shall be enforced as provided in this chapter and not otherwise.
