(a) The surety upon any bond taken by any court of probate, or any person interested in the bond, may at any time make written application to such court for an order requiring the principal to exhibit fully in writing before such court the condition of the estate held by him, so that it may be ascertained whether the estate is being properly managed. Thereupon the court shall cause reasonable notice of such application to be given to the principal. If, upon hearing, the court finds that such application was made in good faith, it shall make such order.
(b) If the principal refuses to obey such order or if, upon his obeying it, the court finds that the estate is not being properly managed by him, it shall remove him and appoint another in his place.
