Can student loan money be garnished from a joint checking account?

Question Details:

I am a college student and I applied for federal student aid through FAFSA. I took out more than my tuition bill was for so I received a federal refund of $6700. I had them deposit it into my checking account, which my mother's name is also on. My mother was sued for an old credit card debt of hers and they garnished all of her checking accounts, including mine because it had her name on it. Is there anything that I can do to try to get my money back? Can my student loan money be taken for something like that, even if the settlement had nothing to do with me? I can't sue my mom, she has no money. Important Notice
