Okla. Stat. tit. 12, § 12-1081: Death of party after verdict or judgment

(a) If a party dies after verdict is rendered, judgment may be

rendered on the verdict although the representative or successor of

the decedent has not been substituted as a party to the action.

(b) If a plaintiff dies after verdict or after judgment and the

verdict and judgment are in his favor, his representative or

successor may be substituted for him upon motion of any party to the

action with notice to the representative or successor, or

substitution may be made upon motion of the representative or

successor of the decedent. Such motion may be made at any time

before the judgment becomes dormant but it must be made before

action is taken to enforce the judgment. A delay in substituting

the representative or successor of the decedent shall not affect the

validity of a judgment lien.

(c) If a defendant dies after verdict or after judgment and the

verdict and judgment are in favor of the plaintiff, the judgment

shall be filed with the representative of the decedent within the

time allowed for filing other claims and the judgment shall be

treated as if it has been allowed by the representative and it shall

be payable in the due course of administration.
