Why Oklahoma Public Work Runs on a Bond
On a private Oklahoma job, an unpaid subcontractor or supplier files a verified lien statement with the county clerk within 90 days of its last furnishing under 42 O.S. § 143, after the pre-lien notice covered in the Oklahoma pre-lien notice guide . A school bond project in Oklahoma City, an ODOT interchange in Tulsa, a county courthouse in Norman or a water plant in Lawton is different. Public property cannot be liened, so Title 61 puts a payment bond between the unpaid claimant and the public owner. Oklahoma’s bond rule is close to the federal Miller Act in structure. Claimants are split into two groups. Those in contract with the bonded contractor need no notice. Those further down the chain owe a 90-day notice to the contractor, with a copy to the surety. Everyone has one year from their own last day to sue. The Mechanics Lien Management Method treats an Oklahoma public job as a tier-check file . The first question is whether you have a contract with the company that posted the bond. The answer decides whether a missed 90-day letter costs you the claim.
The Bond: Full Contract Sum on Jobs Over $100,000
Under 61 O.S. § 1(A), anyone awarded a contract exceeding $100,000 for construction or repair of a public or private building, structure or improvement on public real property must furnish a bond, with good and sufficient sureties, payable to the state, in a sum not less than the total sum of the contract . Subsection (B) says the bond secures completion of the work and payment of everything the contractor owes its subcontractors and its suppliers of labor, material, rental of machinery or equipment, and repair of and parts for equipment. The Public Competitive Bidding Act repeats the requirement in 61 O.S. § 113(B). On public construction contracts over $100,000, and on construction management trade contracts or subcontracts over $50,000 , the contractor provides the § 1 bond, a performance bond equal to the contract price, and a bond equal to the contract price against defective workmanship and materials for one year after acceptance (one year after completion on Department of Transportation and Turnpike Authority work). The agency may allow up to 60 more days to obtain the bonds under § 113(C). A full-value payment bond is the good news. Unlike states that require only a 50 percent bond, an Oklahoma bond on a qualifying job should cover the whole contract. On a contract of $100,000 or less, though, neither section requires a bond, so confirm one exists before you rely on it.
Who Owes the 90-Day Notice
Read the sentence by tier: The phrase “regardless of tier” matters. Oklahoma does not stop at the second tier the way the federal Miller Act does. A supplier to a third-tier subcontractor is still a claimant, provided it gives the notice. The test is not how far down you are; it is whether you have any contract, express or implied, with the bonded contractor.
What the Notice Says and How It Is Served
Section 2 requires the notice to state, with substantial accuracy: Service is by registered or certified mail , postage prepaid, in an envelope addressed to the contractor at any place it maintains an office or conducts business, together with a copy to the surety or sureties on the payment bond. The safest practice is to send both pieces the same day, by certified mail with return receipt, and keep the receipts and a copy of what was in each envelope. Add more than the statute requires. Name the project, the public owner and the county. Give the bond number from the copy of the bond. List your first and last furnishing dates and attach the unpaid invoices. A surety that can match the notice to a bond file quickly tends to answer sooner.
The One-Year Suit Bar and the Two-Year Exception
Under 61 O.S. § 2(A), no action may be brought on the bond after one year from the day the claimant last performed labor or furnished material or parts for which the claim is made. The clock belongs to each claimant. A drywall supplier whose last delivery was in May and an electrician who finished in October have different deadlines on the same job. The same sentence allows two years if a prior claim was filed within one year of the labor or material. The statute does not say where a claim is filed or what form it takes. Until an Oklahoma court or a lawyer reviewing your file tells you otherwise, do not plan on the second year. Section 2 does not set a waiting period before suit, does not name a venue and does not provide for attorney fees. Ask an Oklahoma construction attorney about venue and fee recovery before you file, because the answer may come from the bond form or from other statutes.
Construction Manager at Risk Jobs
Oklahoma treats at-risk construction management differently. When an at-risk construction manager, or a trade contractor working under an agency or at-risk CM contract, is the party that furnishes the payment bond, Section 2 gives a right of action only to persons in direct contract with the party that furnished the bond . On a CM-at-risk job, find out early which company posted the bond that covers your work. If the trade contractor that hired you posted it, you are in direct contract with the bonding party. If you are a supplier to that trade contractor’s subcontractor, the bond may not reach you at all, and you need payment security from your customer before you ship.
Every Oklahoma Public-Project Claim Deadline in One Table
The Mechanics Lien Management State System calendars the 90-day notice date and the one-year suit bar from your last furnishing date. Private-work rules are on the Oklahoma lien statutes page, with the calculator on the Oklahoma mechanics lien hub . The last row covers federal prime contracts in Oklahoma, such as Tinker Air Force Base, Fort Sill, Vance and Altus Air Force Bases and the McAlester Army Ammunition Plant. Those run under the federal Miller Act , whose notice rule looks like Oklahoma’s but whose suit window also requires a 90-day wait.

Frequently Asked Questions
What is the deadline for an Oklahoma payment bond claim notice?
Ninety days. Under 61 O.S. § 2, a claimant that must give notice has to do so within 90 days from the date it performed the last of the labor or furnished the last of the material or parts for which the claim is made. The clock runs from the claimant's own last day on the job, not from completion of the project or acceptance by the public owner.
Who has to send the 90-day notice in Oklahoma?
Only a claimant with a direct contract with a subcontractor, at any tier, and no contract, express or implied, with the contractor that furnished the payment bond. A sub-subcontractor, a supplier to a subcontractor, or a laborer hired by a subcontractor owes the notice. A first-tier subcontractor or a supplier that sold directly to the prime contractor has no statutory notice to give, although sending one costs little and often speeds payment.
Who do you send an Oklahoma bond claim notice to?
The contractor that furnished the payment bond, with a copy to the surety or sureties on the bond. Section 2 says the notice is served by registered or certified mail, postage prepaid, in an envelope addressed to the contractor at any place it maintains an office or conducts business, together with a copy to the surety. Mailing only the public owner, or only the subcontractor that owes you, does not satisfy the statute.
What must an Oklahoma bond claim notice say?
It must state with substantial accuracy the amount claimed and the name of the party to whom the material or parts were furnished or supplied, or for whom the labor was performed. In practice, also include the project name and location, the public owner, the bond number if you have it, and the dates of first and last furnishing, so the surety can match the claim to the right bond.
How long do you have to sue on an Oklahoma payment bond?
One year from the day the claimant last performed labor or furnished material or parts for which the claim is made. Section 2 extends that to two years if a prior claim was filed within one year of the labor or material. The statute does not say where that prior claim must be filed, so the safe plan is to treat one year as the real deadline and file suit before it runs.
Which Oklahoma public jobs require a payment bond?
Under 61 O.S. § 1, any contract exceeding $100,000 for construction or repair of a public or private building, structure or improvement on public real property requires a bond payable to the state of not less than the total contract sum. Section 113 of the Public Competitive Bidding Act requires the same bond on public construction contracts over $100,000 and on construction management trade contracts or subcontracts over $50,000, along with a performance bond and a one-year defect bond.
How do you get a copy of the payment bond in Oklahoma?
Ask the public agency that awarded the contract. Section 2 requires the bond to be filed in the office of the agency, institution, department, commission, municipality or other government body that entered into the contract, and the officer holding it must furnish a copy to any person claiming rights under it. The copy gives you the surety's legal name and address for the notice.
