Whenever any voucher, bond or interest coupon issued by a county in anticipation of the collection of special assessments under any of the provisions of this Division has been lost, destroyed or stolen, and proof is made to the official of the county charged with making payment on the voucher, bond or interest coupon that the loss, theft or destruction occurred while the voucher, bond or interest coupon was owned by and in possession of the claimant, such official shall issue or cause to be issued and delivered to the claimant a duplicate of such voucher, bond or interest coupon alleged to have been lost, destroyed or stolen after first endorsing on the duplicate all payments of principal and interest made on the original voucher, bond or interest coupon. However, the claimant shall prior to issuance of any such duplicate execute and deliver to the county a bond in penalty at least double the amount of the principal of such voucher, bond or interest coupon alleged to have been lost, destroyed or stolen with sufficient security to be approved by the county official, conditioned to indemnify the county against all claims by any other person on account of such voucher, bond or interest coupon and against all costs and expenses by reason thereof.
