Oklahoma Checking Garnishment

Husband has a checking account (where he receives his pay through DD from DoD) with only his name on it. There is a joint account at the same bank. Judgement was granted against wife's debt (husband is not named in the court documents and is not responsible for the debt). However, both accounts were levied at the bank even the one in husband's name only. Is this legal? Oklahoma is not a community property state. How do we fix this, if possible..
