Okla. Stat. tit. 12A, § 1-9-326
Oklahoma Code Comment
Rules are established for determining priority when the debtor acquires collateral subject to a security interest and then grants an additional security interest and when a debtor who has granted a security interest acquires property covered by a security interest and becomes bound by that interest (as in a merger or purchase and assumption). There are companion provisions governing effectiveness of the security agreement ( section 9-203(d) ) and the financing statement ( section 9-508).
These provisions change the law in most jurisdictions, by permitting the security interest to be enforced against certain transferees of the collateral (and creditors of that transferee), even as to after-acquired collateral acquired by the transferee and even if the transferee and even if the transferee has not signed the security agreement. In Oklahoma, however, these revisions essentially codify Union National Bank of Chandler v. BancFirst (Seminole), 871 P.2d 422 (Okla. 1993); see generally William E. Carroll and Alvin C. Harrell, Article 9 Filings: Russian Roulette B UCC Style, 52 Consumer Fin. L.Q. Rep. 338 (1998).
