§ 31.02  APPROVAL OF BONDS.
   (A)   The official bonds of all municipal officers shall be prepared by the Solicitor.  Except as otherwise provided by state law, they shall be in such sum as the Council prescribes by general or special ordinance and be subject to the approval of the Mayor, except that the Mayor’s bond shall be approved by the Council, or, if it is not legally organized, by the Clerk of the Court of Common Pleas of the County. 
(R.C. § 733.70)
   (B)   In each bond mentioned in division (A) above, the condition that the person elected or appointed shall faithfully perform the duties of the office shall be sufficient.  The fact that the instrument is without a seal, that blanks for the date or amount have been filled subsequent to its execution but before its acceptance, without the consent of the sureties, that all the obligees named in the instrument have not signed it, that new duties have been imposed on the officers or that any merely formal objection exists, shall not be available in any suit on the instrument.
(R.C. § 733.71)
   (C)   Each officer required by law or ordinance to give bond shall do so before entering upon the duties of the office, except as otherwise provided by law.  The Legislative Authority may at any time require each officer to give a new or additional bond.  Each bond, except that of the Auditor or Clerk, upon its approval, shall be delivered to the Auditor or Clerk, who shall immediately record it in a record provided for that purpose, and file and carefully preserve it in his or her office.  The bond of the Auditor or Clerk shall be delivered to the Clerk-Treasurer, who shall in like manner record and preserve it. 
(R.C. § 733.69)
