Conn. Gen. Stat. § 42a-3-205
Special endorsement. Blank endorsement. Anomalous endorsement.
(b) If an endorsement is made by the holder of an instrument and is not a special endorsement, it is a “blank endorsement”. When endorsed in blank, an instrument becomes payable to bearer and may be negotiated by transfer of possession alone until specially endorsed.
(c) The holder may convert a blank endorsement that consists only of a signature into a special endorsement by writing, above the signature of the endorser, words identifying the person to whom the instrument is made payable.
(d) “Anomalous endorsement” means an endorsement made by a person who is not the holder of the instrument. An anomalous endorsement does not affect the manner in which the instrument may be negotiated.
See Sec. 42a-3-206 for successor provisions to Sec. 42a-3-205, revised to 1991, re restrictive endorsements.
Subsec. (d):
Any endorsement by a nonholder is an anomalous endorsement and does not affect negotiability of the instrument. 68 CA 716.
