N.J. Stat. § 40:65-9
Such sidewalk assessments shall bear interest from the time of confirmation at the same rate and with the same penalties for nonpayment as assessments for local improvements in the municipality, and from the confirmation thereof shall be a first and paramount lien upon the real estate assessed to the same extent and be collected and enforced in the same manner as assessments for local improvements. The governing body may provide for the payment and collection of such assessments in installments in the same manner and at the same rate of interest as assessments for local improvements are payable in installments in the municipality. No such assessments shall be invalid by reason of error in the statement or omission of the name of any owner or owners of real estate assessed, or for any other informality, where such real estate has been actually improved.
