All official bonds required by law to be given by any public officer or public employee, excluding executors, administrators and guardians, in this State shall be signed by that officer or employee, and his or her securities, and acknowledged before an officer authorized by law to take acknowledgments of instruments substantially in the following form:
State of _______________
County of ______________
I, _________________, certify that _______________ who is personally known to me to be the same person whose name is subscribed to the foregoing instrument, appeared before me this day in person and acknowledged that he or she signed and delivered the instrument as his or her free and voluntary act.
__________________________ Signature (Seal)
The acknowledgment shall be prima facie evidence that the instrument was signed and acknowledged in the manner stated and shall have the same effect as evidence in all legal proceedings as that given to an acknowledgement of a deed of conveyance of real estate. Each public officer or employee who is required to give an official bond may be required by the court, officer, or board whose duty it is to take or approve the bond, to give additional surety or new bond whenever the security of the original bond has become insufficient by the subsequent insolvency, death or removal of any of the sureties, or when for any cause the bond is deemed insufficient. Any officer or employee who fails to give bond when required, under this Section, within 10 days after he or she is notified in writing of the request, shall be deemed to have vacated his or her office.
