New Jersey Statutes Appendix - Former Title 3A Administration of Estates Decedents and Others 3A § 29-4

Where the federal agency, the sureties on the guardian's bond, any person interested in the benefits in the hands of such guardian or any person as next friend of the ward serves notice upon the guardian that his account has not been filed in accordance with chapters 27 to 31 of this title (§ 3A:27-1 et seq.), and where the guardian fails to render the account within 30 days from the date of mailing of the notice or from the time of service or within such time as the court may otherwise provide, the court to which he is accountable shall remove him. The notice may be mailed to the guardian's last known address.

The cost of the proceedings, as well as the cost incident to an order to show cause when the same is necessary to obtain an accounting, shall be paid by the guardian out of his own estate, unless the court shall otherwise order.
