New Jersey Statutes Appendix - Former Title 3A Administration of Estates Decedents and Others 3A § 20-10

If the personal estate and the income of the real estate of a mental incompetent is insufficient to pay his just debts, to reimburse or pay any person for proper advances or services on his account, or to pay for his support or education or that of his family, household, spouse, child or children, the superior court or the county court to which the guardian is accountable, upon full investigation of all the circumstances, may, from time to time, direct the guardian to sell so much of the timber, growing or being upon the lands of such mental incompetent, or such part of his real estate, as the court may deem adequate and advisable for such purpose.
