I need to chime in here. One should never, ever, ever commingle funds with Social Security. SS is exempt, exempt, exempt (except from the IRS if you owe back taxes) however that exemption ends if the funds are commingled. Once commingled, tracing becomes a huge problem as you cannot tell which dollar came from SS and which came from some other source.
General rule: Open a new account where the ONLY funds deposited are from SS. Use the existing (old) account as you see fit for money coming from other sources. You can withdraw from the SS account as needed but never, ever add to it unless the money so added is SS money.
As to filing a bk, Proserpina is correct. . . you do not necessarily need an attny. You should, however, investigate filing bk by consulting with local bk attnys. Consultations are usually free and each time you meet with an attny you will learn something new. You may very well be judgment proof and, therefore, not need a bk, but filing one may give you some peace of mind.
