N.J. Stat. § 54:4-8.42
No deduction, as provided herein, shall be allowed except upon written application therefor, which application shall be on a form prescribed by the Director of the Division of Taxation, in the Department of the Treasury, and provided for the use of claimants hereunder by the governing body of the municipality constituting the taxing district in which such claim is to be filed and the application has been approved as provided in this act. As to claims for exemption from taxation filed with an assessor on or before November 1, 1963 on forms prescribed by the director, the assessor shall not require of any person who has filed such a claim the filing of an application for a tax deduction but shall approve such person for a tax deduction if it appears from the claim for exemption from taxation that such person meets all the other prerequisites required by this act for the approval of the tax deduction. Each assessor may at any time inquire into the right of a claimant to the continuance of a deduction hereunder and for that purpose he may require the filing of a new application or the submission of such proof as he shall deem necessary to determine the right of the claimant to continuance of such deduction.
