Whenever a jury is required in the probate court, the probate judge shall notify the commissioners of jurors, who shall cause to be drawn from the annual jury list the names of sixteen jurors. Additional names may be drawn if required. The clerk of the court of common pleas or one of the clerk's deputies shall make a list of those names in the order drawn and certify the list to the probate court, and the court shall issue a summons commanding the persons whose names were drawn to appear on the day and at the hour set for trial. The probate court shall deliver the summons to the sheriff, who shall serve it within five days of delivery and make prompt return of the service.
