Okla. Stat. tit. 12A, § 3-110
Oklahoma Code Comment
Sections 3-109 and 3-110 rewrote pre-revision Sections 3-110, 3-111, 3-116 and 3-117, for clarity and to modernize the language. Sub section 3-110(d) clarifies pre-revision Section 3-116 by seeing out guidelines for determining when an instrument payable to two or mote payees must be indorsed by all of them. Essentially, in order to require indorsement by all the payees, their names must be joined in the conjunctive, as in "Jane Doe and John Doe" or "Jane Doe & John Doe." Any other formulation will permit indorsement by only one payee, as with "Jane Doe or John Doe," "Jane Doe/John Doe," or "Jane Doe, John Doe."
Because this Section generally continues prior law, cases like Young v. Hembree, 181 Okla. 202, 73 P.2d 393 (1937), and Enid Bank & Trust Co. v. Yandell, 176 Okla. 550, 56 P.2d 835 (1936), continue to represent proper interpretations under this Section
