Okla. Stat. tit. 12A, § 12A-1-9-709: Priority

PRIORITY

(a) This act determines the priority of conflicting claims to

collateral. However, if the relative priorities of the claims were

established before this act takes effect, former Article 9

determines priority.

(b) For purposes of subsection (a) of Section 1-9-322 of this

title, the priority of a security interest that becomes enforceable

under Section 1-9-203 of this title dates from the time this act

takes effect if the security interest is perfected under this act by

the filing of a financing statement before this act takes effect

which would not have been effective to perfect the security interest

under former Article 9 of this title. This subsection does not

apply to conflicting security interests each of which is perfected

by the filing of such a financing statement.
