The Missouri Petition for Determination of Warship (Sec. 473.633 RSM) is a legal process by which one can establish the succession of ownership rights to an estate of someone who has died without leaving a valid will. It is used when the deceased has no known heirs or the known heirs are unable or unwilling to proceed with the probate process. This petition is filed in the circuit court in the county where the decedent lived or owned property. There are two types of Missouri Petition for Determination of Warship (Sec. 473.633 RSM): a voluntary petition and an involuntary petition. A voluntary petition is initiated by a relative of the decedent who is willing to act as the petitioning party, while an involuntary petition is initiated by a creditor of the decedent or other interested party. In either case, the petition must include the decedent's name and date of death, a description of the decedent's property, a list of potential heirs, and a description of the petitioner's relationship to the decedent. Once the petition is filed, the court will hold a hearing to determine the rightful heirs of the decedent's estate. This process may include gathering evidence from witnesses, examining legal documents, and determining the validity of the will. Once the court has determined the rightful heirs, the estate will be distributed accordingly. The court’s decision is binding on all parties, and any disputes over the distribution must be resolved through a separate legal action.
