(d) The refunding bonds must be approved by the attorney general as provided by Section 772.326 and shall be registered by the comptroller on the surrender and cancellation of the bonds refunded.

(e) The orders or resolutions authorizing the issuance of the refunding bonds may provide that they be sold and the proceeds deposited in the place or places at which the bonds being refunded are payable, in which case the refunding bonds may be issued before the cancellation of the bonds being refunded. If refunding bonds are issued before cancellation of the other bonds, an amount sufficient to pay the principal of the bonds being refunded and interest on those bonds accruing to their maturity dates or to their option dates if the bonds have been duly called for payment before maturity according to their terms shall be deposited in the place or places at which the bonds being refunded are payable.
