Okla. Stat. tit. 12A, § 12A-3-201: Negotiation

NEGOTIATION

(a) "Negotiation" means a transfer of possession, whether

voluntary or involuntary, of an instrument by a person other than

the issuer to a person who thereby becomes its holder.

(b) Except for negotiation by a remitter, if an instrument is

payable to an identified person, negotiation requires transfer of

possession of the instrument and its indorsement by the holder. If

an instrument is payable to bearer, it may be negotiated by transfer

of possession alone.
