Mo. Rev. Stat. § 513.525
Whenever any dwelling house, outbuilding and the land in connection therewith, in which a homestead shall exist, shall exceed the respective value mentioned in section 513.475, and a severance of such homestead would greatly depreciate the value of the residue of the premises, or be of great inconvenience to the parties interested either in such residue or in such homestead, either party may apply to the circuit court by petition, setting forth the facts, for relief; and upon the hearing of such petition, if it shall appear that such homestead cannot be occupied in severalty without great inconvenience to the parties interested in such homestead or in such residue, the court may order such homestead to be transferred to such other parties, and the payment of the value of the homestead interest to the owner thereof; or, at the option of such owner, may order such other parties to transfer such residue to him, and order him thereupon to pay such other parties the value thereof, to be fixed by the court; or, if the case require it, the court may order a sale of the whole premises, and apportion the proceeds between the parties; and such court may make all such orders in the premises as shall be equitable and needful.
