Okla. Stat. tit. 12, § 12-759: Filing and index of execution - Appraisement of property -

Extension of judgment lien.

A. When a general execution is issued and placed in the custody

of a sheriff for levy, a certified copy of the execution shall be

filed in the office of the county clerk of the county whose sheriff

holds the execution and shall be indexed in the same manner as

judgments. At the time the execution is filed, the court clerk

shall collect from the party seeking a general execution all fees

necessary for the payment of the disinterested persons or a legal

entity for services in appraising the subject property pursuant to

the requirements of subsection B of this section.

B. If a general or special execution is levied upon lands and

tenements, the sheriff shall endorse on the face of the writ the

legal description and shall have three disinterested persons who

have taken an oath to impartially appraise the property levied on or

a legal entity which has provided a written affidavit of

impartiality, upon actual view; and the disinterested persons or

legal entity shall return to the officer a signed estimate of the

real value of the property. If an estimate is obtained from a

disinterested legal entity, such estimate shall be developed by the

legal entity using at least three independent, credible sources,

each of which has estimated the real value of the subject property

independently. The disinterested persons or legal entity shall be

paid for such services by the court clerk of the county where the

property is located within thirty (30) days of the date that they

return their estimate of the real value of the property.

C. To extend a judgment lien beyond the initial or any

subsequent statutory period, prior to the expiration of such period,

a certified copy of one of the following must be filed and indexed

in the same manner as judgments in the office of the county clerk in

the county in which the statement of judgment was filed and the lien

thereof is sought to be retained:

1. A general execution upon the judgment;

2. A notice of renewal of judgment;

3. A garnishment summons issued against the judgment debtor; or

4. A notice of income assignment sent to a payor of the

judgment debtor.
