This Oklahoma lien deadline calculator is for original contractors, subcontractors, sub-subs and suppliers. Pick your role and the type of project, then enter your last date of furnishing. It shows each deadline under Title 42 with the statute section next to it.
Subs and suppliers on commercial jobs also enter the amount owed, because the pre-lien notice is required only on claims of $10,000 or more. On a home the owner lives in, it's required on any amount. If you already filed the lien statement, add that date and we'll show when foreclosure is due.
It takes about 20 seconds, and it's free. When you're ready to file, LevelSet Collections sends the pre-lien notice, files the lien statement and affidavit with the county clerk, and gives the clerk the owner's address for its mailed notice, in all 77 Oklahoma counties. Liens are $199 to $500 all-inclusive.
Leave blank if you haven't filed yet. With it, we show the owner-notice and enforcement dates too.
Public project? You can't lien public property, but you can still get paid. Ask us how. We get contractors, subs and suppliers paid on public work across the country through Freedom of Information Act and state public-records requests for the contract and payment bond, and Miller Act and state Little Miller Act bond claims. Call or text (469) 694-8003.
What sinks Oklahoma liens
- Skipping the pre-lien notice on an owner-occupied home because the claim is small.
- Using the general contractor's 4-month deadline when you're a sub or supplier with 90 days.
- Forgetting the notarized pre-lien affidavit at filing.
- Giving the clerk a stale owner address, so the mailed notice never arrives.
- Missing the 1-year foreclosure deadline.

Frequently asked questions
How long do I have to file a mechanics lien in Oklahoma?
4 months after last furnishing if you contracted with the owner (42 O.S. § 142), and 90 days if you're a sub, sub-sub or supplier (42 O.S. § 143). Both are filed with the county clerk where the land sits.
Do I need a pre-lien notice in Oklahoma?
Subs and suppliers send one within 75 days after their last supply, unless the claim is under $10,000 or the job is a residential project of four or fewer units the owner doesn't live in. On a home the owner lives in, it's always required (42 O.S. § 142.6).
How long does an Oklahoma lien last?
Foreclosure has to be filed within 1 year after the lien statement is filed (42 O.S. § 172).
