The personal representative will be able to show Letters Testamentary, issued by the court, showing that he was appointed and has the power to administer the estate. The power of the PR includes the power to bring an eviction proceeding if that is otherwise lawful. Someone who has lived in real property for 11 years might possibly have the right to claim adverse possession, but not if they moved into the property with the permission of the owner. Letters of administration would be issued if there was no will. In that case, the decedent's natural children would inherit, not a neighbor.
