Okla. Stat. tit. 12A, § 1-9-607
Oklahoma Code Comment
Sections 9-607 and 9-608 carry forward the rules found in former section 9-502 , but they are broader in scope, and they also elaborate on those rules and provide answers for questions that arose under former section 9-502 . For example, as Official Comment 5 explicitly points out, a junior secured party may collect and enforce its security interest even if that security interest is subordinate to a conflicting security interest in the same right to payment. See also Official Comment 5 to revised section 9-608 . Former Oklahoma law could be read to the contrary. See Consolidated Equipment Sales, Inc. v. First Bank & Trust Co., 627 P.2d 432 (Okla. 1981); First National Bank and Trust Co. of Norman v. Security National Bank and Trust Co., 676 P.2d 837 (Okla. 1984).
Another example concerns a mortgage note or other obligation secured by real estate as collateral where the secured party has not become the assignee of record of the mortgage. See revised sections 9-203(g) and 9-308(e) . Revised section 9-607(b) allows the secured party (in order to foreclose the mortgage non-judicially under 46 Okla. Stat. Chapters 1-5) to record in the office in which a record of the mortgage is recorded a copy of the security agreement and an affidavit of default. See also revised section 9-619 . Of course, any filing should include what is necessary for the real estate records, such as a legal description.
A third example are the rules in revised section 9-608(a)(3) concerning non-cash proceeds. To illustrate, suppose an enforcing secured party receives a promissory note from an account debtor who is unable to pay in return for extending the due date. The secured party may credit the debtor with the principal amount of the note or may credit the debtor as the note is paid, depending on what is commercially reasonable.
Prior cases under former section 9-502 remain good law. See, e.g., F.D.I.C. v. Hulsey, 792 F. Supp. 729 (W.D. Okla. 1992), aff'd in part, rev'd in part, 22 F.3d 1472 (10th Cir. 1994); In re Hammond, 31 B.R. 517 (Bankr. W.D. Okla. 1983); and Frontier Federal Sav. & Loan v. Commercial Bank, 806 P.2d 1140 (Okla. App. 1990).
