Can I file bankruptcy to get rid of bills, though they are not of any big amount?
No please. Bankruptcy should be your last option to get rid of the debts. Why don;t you try debt snowball method to get out of the debts? If you want to know about this method ask in your next question.
Bankruptcy is a complex legal procedure. But the attorney fee is also there. Too much paperwork and rules. Lots of hassles. Settle your debts as soon as possible. You can call 800-DEBT-913 to explore your options. By the way, do you have secured debts or unsecured debts?
Don't go for it. If you have a small amount of debt you may choose debt consolidation to manage your debts, preferably the debt snowball method. If you have credit card debts you can try balance transfer method.
