Any persons assured by a bond executed in this Court may by motion request the sureties to justify. The motion shall be accompanied by an affidavit showing grounds for believing the sureties to be insufficient, the manner of inquiry and the facts ascertained. If the Court finds that the affiant's belief is well-founded, it may order that either the sureties shall justify within a time specified or a new bond be furnished with sufficient sureties.
