If sufficient security or additional security is not given within the time fixed by the court’s order, the right of the personal representative to administer the estate ceases, and the person next entitled to administer the estate, who will post a sufficient bond, must be appointed. If letters have already been issued to the personal representative, the letters must be revoked and the authority of the personal representative thereupon ceases.
