N.J. Stat. Ann. § 3B:15-22

Whenever a fiduciary which is a bank, trust company, savings bank or national bank, has heretofore given or hereafter gives a bond without surety and it shall appear to the satisfaction of the court, that the person entitled to take the assets of the estate or trust administered by the fiduciary has received the estate or trust, and has by release or other instrument released the fiduciary from liability, the court, with notice or without notice if it be so directed, may cancel the bond given by the fiduciary and discharge it from all liability on the bond.
