New Jersey Statutes Appendix - Former Title 3A Administration of Estates Decedents and Others 3A § 6-42

On application of the guardian of a mental incompetent determined to be such by reason of habitual drunkenness, the court wherein said guardian was appointed may make such order for the safe-keeping if such mental incompetent as it may deem necessary with a view to his reformation, and may, from time to time, alter or modify the same. The court may direct the guardian to place his ward in a proper state institution or in such other proper retreat as it may order.

When a direction is made to place such mental incompetent in a state institution, the guardian may be required to give security, in such amount and form as the court shall direct, for the payment of the expenses of keeping such mental incompetent therein.
