Oklahoma Mechanics Lien

File an Oklahoma mechanics lien to secure payment for construction work. Learn the 4-month and 90-day filing deadlines, the pre-lien notice, and enforcement.

Introduction

An Oklahoma mechanics lien is a legal claim filed against real property by a contractor, subcontractor, or supplier who improved the property and was not paid. Once filed, the lien statement attaches to the property, clouds the title, and can be enforced by a court-ordered sale. That security gives the lien its leverage, and Oklahoma grants the right to it in Title 42 of the statutes. The lien only works if you follow each step on time. A claimant other than the original contractor must usually send the owner a pre-lien notice no later than 75 days after last furnishing. An original contractor files the lien statement within four months of last furnishing, while a subcontractor has 90 days. You must then sue to enforce within one year of filing the lien. DocDraft prepares an Oklahoma lien statement and its notices from your project details, and attorney review is available before you file.

Key Things to Know

  1. 1

    An Oklahoma mechanics lien secures payment against the improved property. Contractors, subcontractors, and material suppliers who furnished material, services, labor, or equipment to improve real property and were not paid can file a lien statement under Okla. Stat. tit. 42.

  2. 2

    A pre-lien notice is due within 75 days for most claimants. Under 42 O.S. 142.6 a claimant other than the contractor must send the owner this notice within 75 days of last furnishing. It does not apply to claims under $10,000 or some residential jobs.

  3. 3

    The filing deadline splits by role. Under 42 O.S. 142 an original contractor files the lien statement within four months after material or equipment was last furnished or labor last performed; under 42 O.S. 143 a subcontractor files within 90 days of the same.

  4. 4

    You must sue to enforce within one year. Under 42 O.S. 172 a foreclosure action must be brought within one year from the time the lien statement is filed with the county clerk, so the enforcement clock runs from your filing date.

  5. 5

    Oklahoma applies the rules strictly. Missing the 75-day pre-lien notice, the four-month or 90-day filing window, or the one-year deadline to sue generally forfeits the lien, though a separate contract claim for the unpaid balance may remain.

  6. 6

    The lien statement must state required details. Under 42 O.S. 142 it must give the amount claimed and the items of the account, the name of the owner, the contractor, and the claimant, and a description of the property, verified by the claimant's affidavit.

  7. 7

    Owner-occupied dwellings require the pre-lien notice. Under 42 O.S. 142.6 no lien on property occupied by an owner as a dwelling is valid unless the pre-lien notice was sent within 75 days of last furnishing, and the usual notice exemptions do not excuse it.

Frequently Asked Questions

An Oklahoma mechanics lien is a claim a contractor, subcontractor, or supplier files against a property they improved but were not paid for. It is perfected by filing a verified lien statement with the county clerk. The lien attaches to the real estate, clouds the title so the owner cannot easily sell or refinance, and can be foreclosed through a court-ordered sale. Title 42 governs it.

Contractors, subcontractors, and material suppliers who furnished material, services, labor, or equipment to improve real property and were not paid can file under Title 42. An original contractor deals directly with the owner; a subcontractor claims through the contractor and must usually send the owner a pre-lien notice first to preserve the right.

It depends on your role. Under 42 O.S. 142 an original contractor files the lien statement within four months after last furnishing material or equipment or performing labor. Under 42 O.S. 143 a subcontractor, or a person claiming through one, files within 90 days of last furnishing. Both run from your last day on the job.

If you are not the original contractor, usually yes. Under 42 O.S. 142.6 you must send the owner a pre-lien notice no later than 75 days after last furnishing. The requirement does not apply where the total claim is under $10,000, or to some residential projects of four or fewer units with no owner-occupant. Only one notice per project is required.

One year. Under 42 O.S. 172 you must bring a foreclosure action within one year from the time the lien statement is filed with the county clerk. Because the window runs from the date you filed the lien, calendar it from filing, not from when the work ended, and confirm the exact filing date.

Missing the 75-day pre-lien notice, the four-month or 90-day filing window, or the one-year deadline to sue generally means the lien is lost, because Oklahoma applies these rules strictly. You may still sue the party who hired you for breach of contract to recover the unpaid amount, but you lose the security the lien provides against the property.

Yes, but the pre-lien notice becomes mandatory. Under 42 O.S. 142.6 no lien on property occupied by an owner as a dwelling is valid unless the pre-lien notice was sent within 75 days of last furnishing. The usual exemptions from that notice, such as the residential carve-out, do not excuse notice on an owner-occupied dwelling.

When the debt is paid, the claimant should file a release of the lien with the county clerk to clear the title. A lien also lapses if no foreclosure action is filed within one year of filing. An owner who disputes a lien can challenge it in court, and having an attorney review the release before filing is an available option.
