Missouri Revised Statutes Title X. Taxation and Revenue § 141.535. Sale of parcel under tax foreclosure judgment stayed, when

1. If a parcel is the subject of an action filed under sections 447.620 to 447.640, the court shall stay the sale of any tax parcel to be sold under execution of a tax foreclosure judgment obtained under this chapter, provided that the party which has brought such an action has paid into the circuit court the principal amount of all land taxes then due and owing under the tax foreclosure judgment, exclusive of penalties, interest, attorney fees, and court costs, prior to the date of any proposed sale under execution. The party bringing such action shall provide written notice of the filing of the action to the court administrator and file with the circuit court in which the action is pending a certificate that such notice has been provided to the court administrator. If the party that brought the action under sections 447.620 to 447.640 dismisses its action prior to gaining temporary possession of the property, it shall recover any amounts paid into the circuit court under this subsection.

2. In any order granting a sheriff's deed under section 447.625 or a judicial deed under section 447.640, the court shall also order the permanent extinguishment of liability against the grantee and the grantee's successors in interest for penalties, interest, attorney fees, and court costs arising from actions to collect delinquent land taxes due on the subject property. The funds paid into the court for land taxes under subsection 1 of this section shall then be paid to the county collector.

3. If an owner of such a property moves the court for restoration of possession of the subject property under section 447.638, the owner shall pay into the circuit court all land tax amounts currently due and owing on the property, including all statutory penalties, interest, attorney fees, and court costs retroactive to the date of accrual, and in the event that an owner of the tax parcel regains possession under section 447.638, funds deposited by the owner under this subsection shall be paid to the county collector, and funds paid into the court by a party under subsection 1 of this section shall be paid out in full to the payer.
