N.Y. Debt. & Cred. Law § 253
A citation may be issued by the court to all parties interested in the estate of such incompetent person or conservatee, as creditors or otherwise, requiring them to appear in court on some day therein to be specified, to make proof of their several claims if they be creditors, and to show cause why a settlement of accounts and proceedings of the committee or conservator up to the date of such hearing should not be had, and if no cause be shown, to attend the settlement of such account. All such citations must be returnable in court, and said court when not otherwise engaged shall always be open for proceedings under this article. Such citations may be issued on petition of such committee or conservator, or of one or more of his sureties, or of a creditor of such incompetent person or conservatee, or other person interested in said estate; and when issued on a petition of a committee, conservator, or his surety, it may be issued at any time after the appointment of such committee or conservator, in any other case, after lapse of one year from the appointment of such committee or conservator, or upon his removal or resignation. A citation issued on petition of a creditor may be addressed to and served on the committee or conservator alone, but on or after the return of such citation, the committee or conservator may have a general citation issued to all parties interested.
