Oklahoma's recorded instrument, affidavit of death and heirship, rests on the general recording statute for affidavits of facts affecting title to land. What a recorded affidavit does, in the statute's words: a rebuttable presumption that facts stated in a recorded affidavit are true as they relate to real estate, its use, or its ownership; and, for a severed mineral interest, valid and marketable title as against adverse claimants once the affidavit has been of record ten years with nothing inconsistent filed16 O.S. § 82; 16 O.S. § 67(A)Verified Sep 24, 2026View source. The effect attaches once the affidavit has been of record for 10 years16 O.S. § 67(C)(4)-(5)Verified Sep 24, 2026View source. It is evidence of the facts it states, not a deed; it does not itself transfer title, and a purchaser, lender or title company decides whether to rely on it.

Who may sign, in the statute's words: for the § 67 marketable-title effect, the maker must be related to the decedent or otherwise have personal knowledge of the facts stated16 O.S. § 67(C)(3)Verified Sep 24, 2026View source. The statute names no witness requirement16 O.S. §§ 67, 82-85 (scan)Verified Sep 24, 2026View source. Title companies commonly ask that the affiant be someone other than an heir, or that two people who know the family sign; the office relying on the affidavit sets what it will accept. It states: That the decedent died without a will; or, if the decedent had a will, that the will was never probated in Oklahoma and a copy of the will is attached; or, if the will was probated, that the severed mineral interest was omitted from the final decree and a copy of the will and final decree is attached; The names of the decedent's heirs and their relationship to the decedent; That the maker is related to the decedent or otherwise has personal knowledge of the facts stated; A description of the land for which the title may be affected by matters covered in the affidavit16 O.S. § 67(C)(1)-(3); 16 O.S. § 84Verified Sep 24, 2026View source.

In Oklahoma, estates with personal property of $50,00058 O.S. § 393Verified Sep 8, 2026View source or less skip probate with the Small Estate Affidavit58 O.S. § 393Verified Sep 8, 2026View source, 10 days58 O.S. § 393Verified Sep 8, 2026View source after death. Real property cannot pass through the affidavit58 O.S. § 393Verified Sep 8, 2026View source; an estate that includes real estate uses a separate process. An estate over the limit does not qualify, and no affidavit is prepared for it.
