Wyoming's unclaimed property program is the Unclaimed Property Division of the State Treasurer's Office in Cheyenne. The Treasurer's page links owners to the official search-and-claim portal.
Wyoming has a mineral-specific rule: mineral proceeds unclaimed for more than three years after becoming payable are deemed abandoned, along with the owner's underlying right to receive them and any proceeds that accrue later. The Treasurer says the three years start when the payor first could not pay because it lost contact with the owner, such as an uncashed or returned check or funds put into suspense.
Dormancy period: 3 years

Wyoming holder reports and payments are due by November 1 for the period ending the previous June 30. When a payor first reports a missing mineral owner it remits everything it holds for that owner. The Treasurer's 2026 notice says Wyoming no longer requires ongoing monthly royalty payments for properties reported earlier; starting with the 2027 reporting period, holders report them in the regular annual report.
Report due: No later than November 1 (reports and remittances)
Covers property held as of: Reporting period ending the preceding June 30
Oil and gas rule: On first reporting a missing owner, the holder remits the full net amount held as of remittance (if the oldest payment is over three years old); each owner is listed once with all wells/leases combined; mineral proceeds are not aggregated. The Treasurer's 2026 notice ends the separate ongoing monthly royalty payments: starting with the 2027 reporting period, holders report those properties and payments in the regular annual report, with extraction-location information. Wyoming-production proceeds are reportable to Wyoming under the rules in § 34-24-117(b).

The Treasurer publishes a holder guide just for mineral proceeds. It says payors must also check for abandoned working interests, delay rentals and overriding royalties, not just royalties in suspense, and should include lease and well names on the report. Its property-type list includes mineral codes MI01 to MI09 and MI99, and its mineral descriptions include royalties, overriding royalties, working interests, bonuses, delay rentals, shut-in and minimum royalties, and aggregate mineral proceeds under $50.
