Okla. Stat. tit. 12 § 1188
The defendant may, at any time after the garnishment affidavit is filed, and before judgment, file with the clerk of the court an undertaking, executed by at least two sureties, resident freeholders of the state, to the effect that they will, on demand, pay to the plaintiff the amount of the judgment that may be recovered against such defendant in the action, with all costs not exceeding a sum specified, which sum shall not be less than double the amount demanded by the complaint on file, or in such less sum as the court shall, upon application, direct. The sureties shall justify their responsibility by affidavit annexed stating a sum which each is worth, in property within this state, over and above all his debts and liabilities and property exempt from execution, the aggregate of which sums shall be double the amount specified in the undertaking. The defendant shall serve a copy of such undertaking, with a notice where and when the same was filed, on the plaintiff. Within three (3) days after the receipt thereof the plaintiff shall give notice to the defendant that he excepts to the sufficiency of the sureties, or he shall be deemed to have waived all objections to them.
