N.J. Stat. § 3B:12-16
Before receiving his letters, a testamentary guardian of a minor shall give bond in accordance with N.J.S. 3B:15-1 et seq., unless the guardian is relieved from doing so by direction of the will of the parent appointing the guardian or by order of the court. However, regardless of the direction, the guardian shall, with respect to property to which the ward is or shall be entitled from any source, other than the parent or other than any policy of life insurance upon the life of the parent, give bond in accordance with that section before exercising any authority or control over the property.
The provisions of this section relieving a testamentary guardian of a minor from giving bond by direction of the will of the parent shall not apply to a testamentary guardian of a minor with a developmental disability. Such guardian shall be bonded pursuant to paragraph (1) of subsection i. of N.J.S. 3B:15-1, unless the guardian is relieved from doing so pursuant to paragraph (2) of subsection i. of N.J.S. 3B:15-1.
