N.J. Stat. § 54:4-49.1
Notwithstanding any provisions of the law to the contrary, any real property on which local property taxes are in default and are uncollectible except Class II railroad property, and the lien therefor unenforceable by reason of any order of any State or Federal court, shall not be included in the total ratables of the taxing district wherein such real property is located for the purpose of apportioning the amount to be raised for county and free county library purposes, and for purposes of regional and consolidated school districts and school districts comprising two or more taxing districts. The county board of taxation shall maintain appropriate records showing the value of such real property not included in the total ratables in the apportioning of county taxes, and determine and record the amount of such taxes annually attributable thereto. When by reason of the rescinding of the State or Federal court order, or otherwise, the taxes in default or uncollectible on such real property are collected by a taxing district, the amount of county taxes attributable to such real property for prior years, as determined by the county board, shall be paid by the taxing district to the county.
