Title Examination Standards
Chapter 1, App.
Chapter 24. Mortgages and Other Liens
§24.3. Release by Personal Representative.

A mortgage release executed by the personal representative of a decedent's estate is sufficient where the personal representative was appointed in Oklahoma, or in any other state of the United States or the territories thereof, provided a certified copy of the personal representative's letters testamentary or of administration reflecting that the person is the duly qualified and acting personal representative of the mortgagee's estate is filed with the county clerk in the county in which the mortgage is recorded.

The 2014 Report of the Title Examinations Standards Committee proposed a new Standard to clarify the authority of a Personal Representative of an estate, appointed by an Oklahoma court or a court of another jurisdiction, to release a mortgage. The Real Property Law Section approved the proposal on November 13, 2014, and the House of Delegates adopted the amendment on November 14, 2014.
