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

In Colorado, a contractor must file its lien statement with the county clerk and recorder within four months after the last day it performed labor or furnished materials. A notice of intent to file a lien statement must be served on the owner or the owner’s agent, and on the prime contractor, at least ten days before the lien statement is filed, by personal service or registered or certified mail, and an affidavit of that service must be filed with the statement. The lien stops holding the property six months after the last work or the completion of the improvement unless an action to enforce it has been commenced, and a notice of that action filed with the county clerk and recorder, within that time. A subcontractor or supplier often has different notice requirements and deadlines. This is C.R.S. §§ 38-22-109, 38-22-110.
