Statutory Durable Power of Attorney
I was made agent (attorney-in-fact) in a Statutory Durable Power of Attorney for my mother. This was executed December 9, 2003 in Texas. My mother died January 23,2004 following surgery for a brain tumor. Her Will written in Oklahoma ~ 1999 has her preacher as the Administrator. I know she wanted me to be the Adminstrator of her Will. Does my being named Agent in the Power of Attorney replace the Adminstrator named in her Will? This Statutory Durable Power of Attorney has broad and sweepin powers including estate, trust and other beneficiary transactions.
