Okla. Stat. tit. 12, § 12-2010: Form of pleadings

FORM OF PLEADINGS

A. CAPTION; NAMES OF PARTIES. Every pleading shall contain a

caption setting forth the name of the court, the title of the

action, the file number, and a designation as in subsection A of

Section 7 of this act. In the petition the title of the action

shall include the names of all the parties, but in other pleadings

it is sufficient to state the name of the first party on each side

with an appropriate indication of other parties. In a third-party

petition the title of the action shall include the names of the

parties to the third-party action; a counterclaim and a cross-claim

shall include the names of the claimants and the parties against

whom the claim is asserted; and a motion and petition in

intervention shall include the names of the intervenors and the

adverse parties. When a party is suing or being sued in a

representative capacity, this should be stated in the title of the

action.

B. PARAGRAPHS; SEPARATE STATEMENTS. All averments of claim or

defense shall be made in numbered paragraphs, the contents of each

of which shall be limited as far as practicable to a statement of a

single set of circumstances; and a paragraph may be referred to by

number in all succeeding pleadings. Each claim founded upon a

separate transaction or occurrence and each defense other than

denials shall be stated in a separate count or defense whenever a

separation facilitates the clear presentation of the matters set

forth.

C. ADOPTION BY REFERENCE; EXHIBITS. Statements in a pleading

may be adopted by reference in a different part of the same pleading

or in another pleading or in any motion. A copy of any written

instrument which is an exhibit to a pleading is a part thereof for

all purposes.
