(a) If, in the opinion of the probate court or upon the petition of an heir, it shall become necessary for the good of any estate placed or about to be placed in the hands of the county administrator for the administrator to give additional security on the bond or to give additional bond with security, the probate court shall have the authority to fix the amount of the bond and shall cite the county administrator to appear at a regular term of the court and show cause, if any, why the additional bond or additional security should not be given.

(b) If, upon the hearing, the county administrator fails to show good cause why the additional bond or additional security should not be given, the probate court shall pass an order fixing the amount of the bond and directing the county administrator to give additional security on or before a day named, which day shall be within 30 days of the date of the order.

(c) Should the county administrator fail, refuse, or neglect to give additional bond or additional security on or before the day fixed in the order of the probate court and fail to show good cause why further time should be allowed, it shall be the duty of the probate court to remove the county administrator and to appoint another for the unexpired term of office. The order of removal shall be recorded as provided for the order of appointment.
