Okla. Stat. tit. 12, § 12-577.2: Use of instructions - Requests - Copies

Whenever Oklahoma Uniform Jury Instructions (OUJI) contains an

instruction applicable in a civil case or a criminal case, giving

due consideration to the facts and the prevailing law, and the court

determines that the jury should be instructed on the subject, the

OUJI instructions shall be used unless the court determines that it

does not accurately state the law. Whenever OUJI does not contain

an instruction on a subject on which the court determines that the

jury should be instructed, the instruction given on that subject

should be simple, brief, impartial and free from argument. Counsel

for either party or parties shall have a right to request

instructions by so requesting in writing.

Each instruction shall be accompanied by a copy, and a copy

shall be delivered to opposing counsel. In addition to numbering

the copies and indicating who tendered them, the copy shall contain

a notation substantially as follows:

"OUJI No. ______" or "OUJI No. ______ Modified" or "Not in OUJI"

as the case may be.
