How can I file for bankruptcy when I have no money or job?

Based on your assertions, you are "judgment proof." In other words, no one can collect from you. Social Security Disability benefits can not be touched by creditors. You own no real estate, and you have no job, so even assuming you are sued, creditors can not collect on the judgment. Unless I am missing information, you may not have to file bankruptcy.

A better question is why you would NEED to file bankruptcy when you have no money and no job. People will always find a way to pay for something they actually need unless they can figure out a way to get someone else to give them a WANT by convincing them it is a NEED. I am too old a dog to believe you have a NEED unless you provide a lot more details.

Generally if you have no money and no job, there is no good reason to file bankruptcy.
