Okla. Stat. tit. 12A, § 12A-3-119: Notice of Right to Defend Action

NOTICE OF RIGHT TO DEFEND ACTION

In an action for breach of an obligation for which a third

person is answerable over pursuant to this article or Article 4 of

this title, the defendant may give the third person notice of the

litigation in a record, and the person notified may then give

similar notice to any other person who is answerable over. If the

notice states (i) that the person notified may come in and defend

and (ii) that failure to do so will bind the person notified in an

action later brought by the person giving the notice as to any

determination of fact common to the two litigations, the person

notified is so bound unless after seasonable receipt of the notice

the person notified does come in and defend.
