Conn. Gen. Stat. § 42a-3-203

(b) Transfer of an instrument, whether or not the transfer is a negotiation, vests in the transferee any right of the transferor to enforce the instrument, including any right as a holder in due course, but the transferee cannot acquire rights of a holder in due course by a transfer, directly or indirectly, from a holder in due course if the transferee engaged in fraud or illegality affecting the instrument.

(c) Unless otherwise agreed, if an instrument is transferred for value and the transferee does not become a holder because of lack of endorsement by the transferor, the transferee has a specifically enforceable right to the unqualified endorsement of the transferor, but negotiation of the instrument does not occur until the endorsement is made.

(d) If a transferor purports to transfer less than the entire instrument, negotiation of the instrument does not occur. The transferee obtains no rights under this article and has only the rights of a partial assignee.

See Sec. 42a-3-204(d) for successor provisions to Sec. 42a-3-203, revised to 1991, re instruments with wrong or misspelled names.
