(a) When transfer effected.--An instrument is transferred when it is delivered by a person other than its issuer for the purpose of giving to the person receiving delivery the right to enforce the instrument.

(b) Rights obtained upon transfer of instrument.--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) Right of transferee to demand indorsement.--Unless otherwise agreed, if an instrument is transferred for value and the transferee does not become a holder because of lack of indorsement by the transferor, the transferee has a specifically enforceable right to the unqualified indorsement of the transferor, but negotiation of the instrument does not occur until the indorsement is made.

(d) Effect of transfer of less than entire instrument.--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 division and has only the rights of a partial assignee.
