Okla. Stat. tit. 54, § 54-1-102: Knowledge and Notice

Knowledge and Notice. (a) A person knows a fact if the person

has actual knowledge of it.

(b) A person has notice of a fact if the person:

(1) knows of it;

(2) has received a notification of it; or

(3) has reason to know it exists from all of the facts known to

the person at the time in question.

(c) A person notifies or gives a notification to another by

taking steps reasonably required to inform the other person in

ordinary course, whether or not the other person learns of it.

(d) A person receives a notification when the notification:

(1) comes to the person's attention; or

(2) is duly delivered at the person's place of business or at

any other place held out by the person as a place for receiving

communications.

(e) Except as otherwise provided in subsection (f) of this

section, a person other than an individual knows, has notice, or

receives a notification of a fact for purposes of a particular

transaction when the individual conducting the transaction knows,

has notice, or receives a notification of the fact, or in any event

when the fact would have been brought to the individual's attention

if the person had exercised reasonable diligence. The person

exercises reasonable diligence if it maintains reasonable routines

for communicating significant information to the individual

conducting the transaction and there is reasonable compliance with

the routines. Reasonable diligence does not require an individual

acting for the person to communicate information unless the

communication is part of the individual's regular duties or the

individual has reason to know of the transaction and that the

transaction would be materially affected by the information.

(f) A partner's knowledge, notice, or receipt of a notification

of a fact relating to the partnership is effective immediately as

knowledge of, notice to, or receipt of a notification by the

partnership, except in the case of a fraud on the partnership

committed by or with the consent of that partner.
