N.J. Stat. § 17:3B-36
If credit under a revolving credit plan is offered and extended in connection with a demand deposit account or other transaction account maintained by the borrower with the bank pursuant to an agreement or arrangement whereby the bank agrees to honor checks, drafts or other debits to the account, which if paid would create or increase a negative balance in the account, by making extensions of credit to the borrower under a revolving credit plan, any charges customarily imposed by the bank under the terms governing the demand deposit or other transaction account in the absence of any associated revolving credit plan, including, without limitation, check charges, monthly maintenance charges, checkbook charges, charges for a check drawn on funds in excess of an available line of credit and other similar charges, may continue to be imposed on the account without specific reference thereto or incorporation thereof by reference in the agreement governing the revolving credit plan and the amount of any charge, to the extent the balance in the demand deposit or other transaction account is insufficient to pay the charge, may be charged to the borrower's account under the plan as a loan thereunder and may be included in the outstanding unpaid indebtedness in accordance with the terms of the agreement governing the revolving credit plan.
