For a claimant to file a lien it first must serve the owner and principal contractor with a notice of intent to file a lien 10 days before the lien statement is filed. The filing of the notice extends the time a claimant may file a lien an additional six months or four months from the completion of the project. A party may not place a lien on the property where the contractor and his surety have executed a performance bond. Parties who would be otherwise entitled to a lien may pursue the contractor and his surety. Engineers are entitled to liens. Colorado Revised Statutes 38-22.
