What is the deadline to file a mechanic’s lien in Montana?

In Montana, a contractor must file the construction lien with the county clerk and recorder no later than 90 days after its final furnishing of services or materials, or 90 days after the owner files a notice of completion. An original contractor who furnishes services or materials directly to the owner at the owner’s request does not have to give the notice of right to claim a lien. When filing, the claimant must certify to the clerk and recorder that a copy of the lien has been served on the owner of record. All actions to enforce the lien must be commenced within 2 years from the date the lien is filed. A subcontractor or supplier often has different notice requirements and deadlines. This is Mont. Code Ann. §§ 71-3-535, 71-3-531, 71-3-562.
