A Missouri Petition for Determination of Warship is a legal document used to establish the rights of heirs to a deceased person’s estate. It is typically used when the deceased person has died without a will, or when the validity of a will is disputed. The petition must be filed in the probate court of the county where the decedent resided at the time of death. The petition must provide the names and addresses of all the heirs, any surviving spouse, any known creditors, and the name and address of the person who is filing the petition. The petitioner must also provide evidence that the decedent has died, such as a death certificate or other legal document. The court will review the petition and make a ruling on whom the rightful heirs are. There are three main types of Missouri Petition for Determination of Warship: Small Estate Petition, Standard Estate Petition, and Formal Estate Petition. The Small Estate Petition is used when the decedent’s estate is valued at less than $40,000, the Standard Estate Petition is used when the estate is valued between $40,000 and $400,000, and the Formal Estate Petition is used when the estate is valued at more than $400,000.
