I need to file a mechanics lien and understand the Colorado requirement to serve a specified 10 days notice of intent to file a lien 1st
You can consider using Levelset services or you can reach out to a construction attorney to advise you.
As to the 10 day notice of intent, you must follow the statute to the letter as to content and service. After 10 days, then the proper form is filed and the clause where you affirm that you served the notice of intent is completed and this is then filed with the clerk and county recorder.
