N.J. Stat. § 18A:66-35.1
In the case of any member who retires without paying the full amount so borrowed, the Division of Pensions and Benefits shall deduct from the retirement benefit payments the same monthly amount which was deducted from the compensation of the member immediately preceding retirement until the balance of the amount borrowed together with the interest is repaid. In the case of a pensioner who dies before the outstanding balance of the loan and interest thereon has been recovered, the remaining balance shall be repaid from the proceeds of any other benefit payable on the account of the pensioner either in the form of monthly payments due to his beneficiaries or in the form of lump sum payments payable for pension or group life insurance.
