Okla. Stat. tit. 58, § 58-108: Presumed renunciation of executorship

If the person named in a will as executor, for thirty (30) days

after he has knowledge of the death of the testator, and that he is

named as executor, fails to petition the proper court for the

probate of the will, and that letters testamentary be issued to him,

he may be held to have renounced his right to letters, and the court

may appoint any other competent person administrator, unless good

cause for delay is shown.
