New Jersey Statutes Title 54. Taxation 54 § 4-129

In the event that it is made to appear to the court that the owner or any person interested in such real property has filed an appeal from or is contesting the taxes assessed and levied against such real property, the court shall limit the amount of taxes to be collected by the receiver to the portion of such delinquent taxes which are not in substantial dispute and, if the parties are unable to agree upon the amount thereof, the same shall be ascertained by the court and the collection of the disputed portion of the taxes shall be stayed until the final determination of the proceedings to review said taxes. Thereupon, in the event that such appeal or contest shall be sustained as to any part or all of such taxes so collected, the court shall direct the collector to pay back and return to such owner or person interested in such real property, such part or all of such taxes so collected as to which the appeal or contest has been sustained. In the event that such appeal or contest is not sustained, then the receiver shall proceed to collect from such rents and income any uncollected portion of such delinquent taxes, penalties, interest and costs and expenses as aforesaid.
