Very good point above @Deidre ..... So while you can sign on dads behalf now (if he can't ) on a property settlement application, your POA will end if he passes & the executor named in his will (or appointed administrator as the case may be) will become a party to the settlement proceedingsPerson taking over is the executor named in the will. POA losses effect with the death of the maker.
Who is named as executor of his estate in his will?
