(a) Supporting Instruments. Proof required by R. 4:64-1 may be submitted by affidavit, unless the court otherwise requires. The moving party shall produce the original mortgage, evidence of indebtedness, assignments, claim of lien (N.J.S.A. 46:8B-21), and any other original document upon which the claim is based. In lieu of an original document, the moving party may produce a legible copy of a recorded or filed document, certified as a true copy by the recording or filing officer or by a New Jersey attorney, or a copy of an original document, if unfiled or unrecorded, certified as a true copy by a New Jersey attorney.
(b) Contents of Proof of Amount Due. If the action is uncontested, the plaintiff shall file with the Office of Foreclosure an affidavit of amount due, which shall have annexed a schedule as set forth in Appendix XII-J of these rules. The schedule shall state the principal due as of the date of default; advances authorized by the note or mortgage for taxes, hazard insurance and other stated purposes; late charges, if authorized by the note or mortgage, accrued to the date of the filing of the complaint; a computation of accrued interest; a statement of the per diem interest accruing from the date of the affidavit; and credit for any payments, credits, escrow balance or other amounts due the debtor. Prejudgment interest, if demanded in the complaint, shall be calculated on rate of interest provided by the instrument of indebtedness. A default rate of interest, if demanded in the complaint and if reasonable, may be used to calculate prejudgment interest from the date of default to the judgment. The schedule shall include notice that there may be surplus money and the procedure for claiming it. The proof of amount due affidavit may be supported by computer-generated entries.
(c) Time; signatory. The affidavit prescribed by this rule shall be sworn to not more than 60 days prior to its presentation to the court or Office of Foreclosure. The affidavit shall be made on personal knowledge of all the facts recited therein, and if the affiant is not the plaintiff, it shall also state that the affiant is authorized to make the affidavit.
