How many days do you have to file a mechanics lien in New Hampshire?
New Hampshire does not use a recorded lien claim for private jobs. The lien is secured by attaching the property through a court writ, which must be done while the lien lasts, which is 120 days after the services were performed or materials furnished. Work or materials worth $15 or more is covered.1 RSA 447:2, 447:9 and 447:10
Do you need a preliminary notice in New Hampshire?
A subcontractor or supplier who has no contract with the owner must give the owner, or whoever has charge of the property, written notice that they will claim a lien, before doing the work or delivering the materials. A notice given later is valid for the amount still due from the owner to the contractor at that time. After giving notice, the claimant must send the owner a written account of labor and materials at least once every 30 days.1 RSA 447:5, 447:6 and 447:8

Attaching creditors share pro rata, and an attachment ranks ahead of a construction mortgage except to the extent the mortgage money went to pay subcontractors and suppliers.1 RSA 447:9, 447:10, 447:12 and 447:12-a
