30-3-204. Special indorsement -- blank indorsement -- anomalous indorsement. (1) If an indorsement is made by the holder of an instrument, whether payable to an identified person or payable to bearer, and the indorsement identifies a person to whom it makes the instrument payable, it is a "special indorsement". When specially indorsed, an instrument becomes payable to the identified person and may be negotiated only by the indorsement of that person. The principles stated in 30-3-126 apply to special indorsements.
(2) If an indorsement is made by the holder of an instrument and it is not a special indorsement, it is a "blank indorsement". When indorsed in blank, an instrument becomes payable to bearer and may be negotiated by transfer of possession alone until specially indorsed.
(3) The holder may convert a blank indorsement that consists only of a signature into a special indorsement by writing, above the signature of the indorser, words identifying the person to whom the instrument is made payable.
(4) "Anomalous indorsement" means an indorsement made by a person that is not the holder of the instrument. An anomalous indorsement does not affect the manner in which the instrument may be negotiated.
