N.Y. Debtor & Creditor Law § 69

§ 69. Opposing creditor to file specifications, and may demand jury\ntrial. In order to entitle a creditor to oppose the discharge of the\ninsolvent, he must, on the day fixed to show cause, or at such other\ntime as the court may direct, file with the clerk a specification of his\nobjections; and he may then, but not afterwards, demand a trial, by a\njury, of the questions of fact arising thereupon. If a trial by a jury\nis not then demanded, the questions of fact must be tried by the court,\nwithout a jury. Where one of two or more opposing creditors demands a\ntrial by a jury, all the material questions of fact, arising upon the\nobjections of all the creditors, must be tried in like manner, and at\nthe same time.\n
