Bankruptcy and Bank Accounts?

I am buried in debt right now. I have a $12,000 judgement against me for a repossessed car, and another judgement on the way for around $3,000 for a charged-off credit card. I am planning on filing Chapter 7 bankruptcy when I am financially able. Can I open a bank account before I do that? I've already talked to a bank, and have been approved for a second-chance account, but am hesitant to pull the trigger for fear that the money inside of it will eventually be found by my creditors. There was already an attempt to garnish my wages at my previous job, but I quit three weeks after I got the notice, and they can't seem to figure out where I work now, because I have received no other notices. Any insight??
