2A:44A-7. Mailing of lien claim by claimant
7. Within 10 business days following the filing of a lien claim, the claimant shall, by personal service or registered or certified mail, return receipt requested, postage prepaid, serve or mail a copy of the lien claim as prescribed in section 8 of this act to the last known business address or place of residence of the owner and, if any, of the contractor and the subcontractor, against whom the claim is asserted. Proof of timely mailing shall satisfy the requirement of service of the lien claim. The service of the lien claim provided for in this section shall be a condition precedent to enforcement of the lien; however, the service of the lien claim outside the prescribed time period shall not preclude enforceability unless the party not timely served proves by a preponderance of the evidence that the late service has materially prejudiced its position. Disbursement of funds by the owner, a contractor or a subcontractor, or the creation or conveyance of an interest in real property by the owner, without actual knowledge of the filing of the lien claim, shall constitute prima facie evidence that the party has been materially prejudiced.
