Okla. Stat. tit. 12A, § 12A-8-105

Notice of Adverse Claim.

(a) A person has notice of an adverse claim if:

(1) the person knows of the adverse claim;

(2) the person is aware of facts sufficient to indicate

that there is a significant probability that the

adverse claim exists and deliberately avoids

information that would establish the existence of the

adverse claim; or

(3) the person has a duty, imposed by statute or

regulation, to investigate whether an adverse claim

Oklahoma Statutes - Title 12A. Uniform Commercial Code Page 425

exists, and the investigation so required would

establish the existence of the adverse claim.

(b) Having knowledge that a financial asset or interest therein

is or has been transferred by a representative imposes no duty of

inquiry into the rightfulness of a transaction and is not notice of

an adverse claim. However, a person who knows that a representative

has transferred a financial asset or interest therein in a

transaction that is, or whose proceeds are being used, for the

individual benefit of the representative or otherwise in breach of

duty has notice of an adverse claim.

(c) An act or event that creates a right to immediate

performance of the principal obligation represented by a security

certificate or sets a date on or after which the certificate is to

be presented or surrendered for redemption or exchange does not

itself constitute notice of an adverse claim except in the case of a

transfer more than:

(1) one (1) year after a date set for presentment or

surrender for redemption or exchange; or

(2) six (6) months after a date set for payment of money

against presentation or surrender of the certificate,

if money was available for payment on that date.

(d) A purchaser of a certificated security has notice of an

adverse claim if the security certificate:

(1) whether in bearer or registered form, has been

indorsed "for collection" or "for surrender" or for

some other purpose not involving transfer; or

(2) is in bearer form and has on it an unambiguous

statement that it is the property of a person other

than the transferor, but the mere writing of a name on

the certificate is not such a statement.

(e) Filing of a financing statement under Article 9 of this

code is not notice of an adverse claim to a financial asset.
