New Jersey Statutes Appendix - Former Title 3A Administration of Estates Decedents and Others 3A § 6-27

The surrogate's court of the county where any minor resides, or the superior court, may limit and restrict letters of guardianship to a particular fund or a particular portion of the property or estate of the minor. In such cases the authority and duty of the guardian shall be limited to receiving and administering the fund or particular portion of the property and estate of the minor as is mentioned in the letters of guardianship.

In all other respects such limited and restricted guardianships shall be subject to the laws of this state applicable to general guardianships. No such limited guardian shall be appointed under the provisions of this section if there is a general guardian for such minor legally qualified and acting on his behalf in this state.
