What information should I bring to the first interview?

In short, you should bring as much information as you have.  The more information that you can give your attorney at the first interview; the more complete of a consultation they will be able to give you.  Some important things to bring are your bills, especially medical bills and pay day loans because those often won’t appear on a credit report; paycheck stubs because people often don’t understand what they are actually bringing home.  And tax returns.
It’s also a good idea to look through a budget.  Your attorney will often go through a budget with you during your consultation, but it’s good to get an idea of what you’re spending and where your money is going.  That way, your attorney can formulate a good plan for you to file bankruptcy and move forward in a positive direction.  You should also consider bringing funds in order to hire your attorney.  The sooner you file bankruptcy, the sooner you are going to get out of debt and the sooner you are going to be stress free, debt free and living a happy, stress-free, debt free life.
