If the order applied for by written motion is one to which mover is clearly entitled without supporting proof, the court may grant the order ex parte and without hearing the adverse party.
If the order applied for by written motion is one to which the mover is not clearly entitled, or which requires supporting proof, the motion shall be served on and tried contradictorily with the adverse party.
The rule to show cause is a contradictory motion.
