Okla. Stat. tit. 5, § 5-8: Adverse party - Liability on settlement or compromise of

claim involving lien - Lien as against judgment debtor - Enforcement

of lien.

Should the party to any action or proposed action whose interest

is adverse to the client contracting with an attorney settle or

compromise a cause of action, claim or judgment wherein any lien

perfected under Sections 6 and 7 of this title is involved and such

settlement or compromise is made without the consent of the attorney

holding such lien, such adverse party shall thereupon become liable

to such attorney for the fee that was due or would have become due

under a contract of employment but for the settlement. After

judgment in any court of record, the attorney's lien provided for

herein may also be effective against the judgment debtor upon

endorsement of the words "subject to the attorney's lien in favor of

[insert name]" on the judgment. An attorney may enforce any lien

provided for by this act in any court of competent jurisdiction by

action filed within one (1) year after the attorney becomes aware of

such compromise or payment of such judgment, or judgment may be

rendered on motion in the case in the court in which the suit was

brought.
