From November 1, 2026, Oklahoma has a separate rule for mineral proceeds: proceeds that were not sent to the State Treasurer's Mineral Owner's Fund are presumed abandoned 36 months after they were due to the owner (HB 1371, amending 60 O.S. § 658(C)). Other intangible property keeps the general five-year period, and mineral proceeds never have to be reported or remitted sooner than six months after first sale from the well.

When the owner is deceased, the Treasurer pays only on a certified copy of court or other lawful documents showing the claimant's entitlement. Claims of $10,000 or more also need a certified death record, and a small-estate affidavit can be used only for accounts that came from a bank, credit union or savings and loan.
Documents: Certified copy of court or other lawful documents establishing entitlement to the decedent's property; for claims of $10,000 or more, a government-issued certified record of death; a small estate affidavit (6 O.S. § 906) may be used if the account came from a bank, credit union or savings and loan; the Treasurer may ask for more.

HB 1371 (effective November 1, 2026) also had the State Treasurer set up a separate escrow account within the Mineral Owner's Fund, which already existed under 52 O.S. § 553. When proceeds stay unpaid for 36 months after they first became due and the payor has had contact with the owner, the payor may remit them with accrued statutory interest to the Fund (52 O.S. § 570.10(H)(1)). Proceeds held because a probate is needed to cure title, because of a statutory lien or the owner's written request, or because a payment was returned as undeliverable or not cashed must instead be remitted to the Fund within 180 days after they become due (§ 570.10(H)(8)). Owners recover money in the Fund from the Treasurer with proof of identity and ownership. Separately, if proceeds from an Oklahoma mineral interest stay presumed abandoned for 15 years, the mineral interest becomes subject to sale under 84 O.S. §§ 271.1-277 (60 O.S. § 658.1).
