New Jersey Statutes Title 54. Taxation 54 § 51A-7

The tax court may, upon the filing of a complaint at any time during the tax year or within the next 3 tax years thereafter, by a property owner, a municipality or a county board of taxation, enter judgment to correct typographical errors, errors in transposing, and mistakes in tax assessments, provided that such complaint shall set forth the facts causing and constituting the error or errors and mistake or mistakes, or either thereof sought to be corrected and that such facts be verified by affidavits submitted by the plaintiff. The tax court shall not consider under this section any complaint relating to matters of valuation involving an assessor's opinion or judgment. Any complaint so submitted shall contain a certification that a copy of the complaint and all exhibits thereto have been filed with the county board, and served upon the property owner or the municipality, or both, as may be appropriate in the case of each plaintiff. Any party required to receive a copy of the complaint pursuant to this section may file an answer to the complaint with the tax court pursuant to rules of court. The tax court may require further proof and grant or deny the complaint as it may deem necessary or proper.
