A discharge in bankruptcy is like a "get out of debt" card. It means that you no longer have to pay back certain debts. The court gives you this discharge after you successfully complete a bankruptcy case. This means that creditors can't try to collect money from you for those debts anymore.
Not all debts can be discharged in bankruptcy. For example, you still have to pay back money you owe for things like student loans, taxes, and child support, court fines and fees. You will also continue to make payments on your vehicle and your home if you are keeping them.
