The probate judge, at any time before the final settlement of the accounts of an assignee for the benefit of creditors, may require his attendance, or that of any other person as a witness, and examine him upon oath, as to all matters appertaining to the estate of the assignor or to the administration of the trust, and, upon or after such examination, make and enforce any orders upon proper parties, which said judge deems necessary to prevent a fraudulent transfer or change in the property or effects of the assignor or the allowance or payment of any unjust or fraudulent claim out of his estate.
