Okla. Stat. tit. 61 § 137
Any contract which has been bid under the provisions of the Public Competitive Bidding Act, Section 101 et seq. of Title 61 of the Oklahoma Statutes, and on which no work has been performed and no formal claim or litigation has been pending within the last twenty-four (24) months shall be terminated by the public agency which awarded the contract. After termination, the public agency shall determine the amount of any final payment due to the contractor and shall make such payment to the contractor at the contractor's last-known address, or if the public agency is unable to locate the contractor, the amount due shall be held in a separate account by the State Treasurer in the name of the contractor. Termination of the contract and payment to the contractor or deposit of the funds due to the contractor as determined by the public agency shall release the public agency from any further liability to the contractor or surety company. Any such funds held by the State Treasurer for the contractor which are not claimed by the contractor within thirty-six (36) months from the date of deposit with the State Treasurer shall be deposited in the General Revenue Fund and the state shall have no further liability on the project to the contractor or surety company.
