Okla. Stat. tit. 12, § 12-2021: Misjoinder and nonjoinder of parties

MISJOINDER AND NONJOINDER OF PARTIES

Misjoinder of parties is not ground for dismissal of an action.

Parties may be dropped or added by order of the court on motion of

any party or of its own initiative at any stage of the action and on

such terms as are just. Any claim against a party may be severed

and proceeded with separately. In determining whether to add or

drop parties under this section, the court shall consider if in the

interest of justice such action provides a fair and convenient forum

for all parties.
