Conn. Gen. Stat. § 42b-5: Signature of authorized officer on certificates. Continuing validity.

(a) Any certificated registered public obligation signed by the authorized officers at the time of the signing thereof shall remain valid and binding, notwithstanding that before the issuance thereof any or all of such officers shall have ceased to fill their respective offices.

(b) Any authorized officer empowered to sign any certificated registered public obligation may adopt as and for the signature of such officer the signature of a predecessor in office in the event that such predecessor's signature appears on such certificated registered public obligation. An authorized officer incurs no liability by adoption of a predecessor's signature that would not be incurred by such authorized officer if the signature were that of such authorized officer.
