N.J. Stat. § 17:9A-281
The commissioner shall verify all balances due depositors by causing a notice to be mailed to each depositor at his address as it appears on the records of the bank. The notice shall state the amount of the deposit balance as it appears on the bank's records, and shall instruct the depositor that, if he disputes the amount thereof, he shall within sixty days from the date of the mailing of the notice to him, file a claim with the commissioner for the amount he claims to be due him, and, in default thereof, his claim will be allowed only in the sum stated in the notice. The failure of a depositor to file a claim within the time so limited shall be conclusive evidence of the depositor's assent to the correctness of the balance stated in the notice. An affidavit of the mailing of notices pursuant to this section shall be filed in the department.
