Every guardian who is required to post a bond and who does so other than through a duly authorized surety company shall renew his bond before the clerk every three years during the continuance of the guardianship. The clerk shall issue a citation against every such guardian failing to renew his bond, requiring the guardian to renew the bond within 20 days after service of the citation. On return of the citation duly served and failure of the guardian to comply, the clerk shall remove the guardian and appoint a successor. This section shall not apply to a guardian whose bond is executed by a duly authorized surety company.
