N.J. Stat. § 54:4-29: Purchaser of realty may present deed to assessor for certificate

In all taxing districts, whether assessment maps have been adopted or not, when a change of ownership of real estate occurs, the new owner may present his deed or other evidence of title to the assessor or other proper custodian of the assessment maps, if any there be. Such officer shall properly note and record on the books and maps, if any, the proper change of ownership, and shall certify that he has done so upon the deed or other instrument of transfer.
