I need to file alien on Dilido project to all that were sent prelim...pease verify procedur and cost and timing to do so

You should do this right away. You have 90 days after your final furnishing of labor, materials or service to record a claim of lien. If you are a sub or supplier, you will need to have served a notice to owner before you can record a claim of lien.

Expect to pay about $600-$700 to have a lien prepared and recorded.
