Any property owner, or his agent, may pay his assessment wholly or in part, either before or after the same is due, and whether or not the assessment has been withdrawn from collection or the property assessed has been sold to any municipality or forfeited to the State for the non-payment of such assessment, with the bonds or vouchers heretofore or hereafter issued under this Act on account of such assessment, applying, however, the bonds and vouchers of each series only to the payment of the installments to which they relate. In making such payments, such vouchers and bonds shall be taken at their par value and interest accrued to the date of making such payment. All vouchers and bonds received in payment of such assessment shall be cancelled by the officer receiving the same, as of the date of their receipt, and deposited with the treasurer of the said town or village or the City Comptroller of the City issuing the same. Provided, however, that when the amount of the assessment is less than that of the bond or voucher, the officer receiving the same shall issue a receipt for the balance which shall entitle the owner to the same rights, except as to negotiability, as if the receipt were the original bond or voucher in the amount of the balance.
Any such endorsement on any such bond or voucher shall be made by writing or stamping across the face thereof the words "Payments upon this bond (or voucher) are listed upon the back".
