we are a material supplier - I need to know if we do not send monthly statement of account on jobs in NH does this preclude us from filing a lien for non-payment? I need to know if it is a REQUIREMENT per state statute. Or please send me the language in the statute. Also do you have a matrix for all states requiring monthly statements be sent to parties up the chain from us? From LEVELSET website: New Hampshire Preliminary Notice Deadlines 30 Days Best Practice: Notice of lien rights served on owner prior to providing labor or materials. Delivery of written account of labor and/or material furnished every 30 days (for the previous 30 days).
