Despite the comment above, your son should not care about his credit score and he is not going to qualify for any loan since he does not have a job.
He would be looking at a Chapter 7 and, assuming he has not worked in the past 6 months, would most likely qualify as he currently has little or no income. A Chapter 7 will wipe the slate clean.
I just did a bk for a person in a ½ way house. This person could not meet with me. I did speak to him/her over the phone to confirm his/her wish to file bk but, most of my communication, including the initial conference, was with a family member. We then had someone meet with him/her at the ½ way house to review and sign the documents. (Where there is a will there is a way).
You should meet with a local bk attorney to discuss your son's options.
