What is the deadline to file a mechanic’s lien in Oklahoma?
In Oklahoma, a contractor who contracted with the owner must file a lien statement, verified by affidavit, with the county clerk of the county where the land is located within four months after it last furnished material or equipment or last performed labor. The pre-lien notice in 42 O.S. § 142.6 is required of claimants other than an original contractor, so a contractor who contracted directly with the owner sends none. Within five business days after the statement is filed, the county clerk mails notice of the lien to the owner by certified mail, using the address the claimant furnishes. An action to enforce the lien must be brought in the district court of the county within one year from the filing of the lien with the county clerk. A subcontractor or supplier often has different notice requirements and deadlines. This is 42 O.S. §§ 141, 142, 142.6, 143.1, 172.
