Attorney Caldwell hits it on head exactly: your question is impossible to answer fully as to open ended a question. So I state as follows in paragraph below. But trustee meeting here is about 1 min long assuming no real estate..up first out in 3 min, up 20..means an hour there! You will provide by law the last 60 days proof of income which if income is like Social Security then your bank statements will work; also any bank statements on date of filing must be provided post filing. Trustee ONLY gets $60 to handle your case so they rely on your sworn schedules as to assets owned!
You need and want to enjoy your fresh start also. But the most important thing is to meet with an attorney as you asking this question means you have not. You care about 2 goals: keeping everything you have equity in and discharging all your debts. If you don't have any of the exceptions to discharge you will obtain that goal; most exceptions are set forth in 11 USC. 523 (Google it) like child support, some income taxes, traffic (in a ch 7) and criminal fines , and presumption of student loans. But some debts are dischargeable in a ch 13 but NOT in a ch 7 so you want to make sure and your attorney will discuss any such types with you also!
Your exemptions depend on what state you have lived in in the last 2 years and thus if in your state, then your states exemptions will apply. Most persons filing keep everything they own but your attorney will confirm that with you when they learn everything you own and the equity thereof!
Some secured debts like homes, vehicles, other secured debts an attorney will discuss your options on also as you must list any debts; but that does not mean you will lose them unless you have too much equity or are in default on paying for them! Discuss those options if they apply with your attorney too.
But other issues can arise that can greatly harm your case. Just one example: If you paid back a relative $3,000 11 months ago and now file bankruptcy next week, the trustee can SUE that relative to retrieve that $3,000 (under what is called a preference) for the benefit of the bankruptcy estate. As a result, most attorneys don't charge to meet with them the first meeting so meet with one no matter what.
Many great attorneys can be found right here on AVVO in your state so look, call, and meet one as soon as you can.
You should also want to know when to file: is there an advantage of waiting versus filing now and who should you pay between now and then! Good luck and enjoy your later fresh start.
