Section 44. Upon complaint to a probate court by a person interested in the estate of a deceased person against a person suspected of having fraudulently received, concealed, embezzled or conveyed away any property, real or personal, of the deceased, the court may cite such suspected person, although he is executor or administrator, to appear and be examined on oath upon the matter of the complaint. If the person so cited refuses to appear and submit to examination, or to answer such interrogatories as may be lawfully propounded to him, the court may commit him to jail until he submits to the order of the court. The examination shall be had and recorded in such manner as the court shall direct, and the final record shall be signed by the party examined. A proceeding hereunder shall be entitled ''petition for discovery''.
