If Your Contract is with the Property Owner
If your contract is with the property owner, then you must send a copy of the filed lien affidavit by registered or certified mail to the owner’s last known business or residential address no later than the fifth day after the date that the lien was filed.
If Your Contract is with Anyone other than the Owner
If you do not have a direct contract with the property owner, then must send a copy of the filed lien affidavit by registered or certified mail to the owner’s and all “upstream” contractor’s last known business or residence address no later than the fifth day after the date that the lien is filed.
Failure to comply with this requirement may render the lien void.
