The estate planning process is more complicated if you own real estate in different states because each state’s probate court only has authority over property located in their own state. Thus, if you are a Washington State resident and own a home here, a Washington State probate court can oversee that property’s transfer to your heirs, but it can’t do anything about your timeshare in Hawaii or your mountain vacation home in Colorado. The properties in those states will have to go through an ancillary probate process in the states where they are located. Your personal representative may have to travel there, and you’ll probably need a lawyer in each state.
