Today, it is common for retirees to have residences in multiple states. Some choose to keep his or her family home and acquire a small home in Florida to visit during the cold months. When a person who owns residences or financial accounts in two different states passes, an ancillary probate proceeding must be commenced where the other real property is located. An ancillary proceeding is an administrative proceeding that is required in addition to the original probate process of a Last Will & Testament. Usually, this administrative proceeding is required because a person owns real property outside of his or her home state.
