1.  Proceedings independent.  Each proceeding before the court or register is independent of any other proceeding involving the same estate;  

2.  Petitions for formal orders.  Petitions for formal orders of the court may combine various requests for relief in a single proceeding if the orders sought may be finally granted without delay. Except as required for proceedings that are particularly described by other sections of this Article, a petition is not defective because it fails to embrace all matters that might then be the subject of a final order;  

3.  Petitions for appointment of personal representative.  Proceedings for probate of wills or adjudications of no will may be combined with proceedings for appointment of personal representatives; and  

4.  Order.  A proceeding for appointment of a personal representative is concluded by an order making or declining the appointment.
