Okla. Stat. tit. 12 § 1182
The proceedings against a garnishee shall be deemed an action by the judgment creditor against garnishee and defendant, as parties defendant, and all of the provisions for enforcing judgment shall be applicable thereto. No trial shall be had of the garnishee action until the judgment creditor shall have judgment in the principal action, and if the defendant have judgment, the garnishee action shall be dismissed with costs, unless the judgment creditor shall perfect an appeal according to law, in which event the garnishment proceeding shall be continued until the disposition of the appeal, and it shall not be necessary to appeal the garnishment proceedings, or make the garnishee a party to the appeal. The court shall render such judgment in all cases as shall be just to all of the parties and shall properly protect their respective interests, and may adjudge the recovery of any indebtedness, the conveyance, transfer, or delivery to the sheriff, or any officer appointed by the judgment, of any property disclosed or found to be liable to be applied to the judgment creditor's demand, or by the judgment pass the title thereto; and may therein, or by its order when proper, direct the manner of making sale and of disposing of the proceeds thereof, or of any money or other things paid over or delivered to the clerk or officer. The judgment against a garnishee shall acquit and discharge from all demands by the defendant or the defendant's representatives for all moneys, goods, effects, or credits paid, delivered or accounted for by the garnishee by force of such judgment; provided, it shall be no defense to proceedings against a garnishee that the debt owing by the garnishee to the defendant was unliquidated or was not due.
