he needs legal assistance NOW...........
as far as bankruptcy courts (any courts) are concerned anything sold within 3 years of the court date/filing are still counted as owned so that expensive car or the value of it is an asset even if he does not own it......... selling the cars now will NOT help him in any way at this time.
he can NOT file for bankruptcy (chapter 7 or 13) without going through consumer counseling and the counseling agency will determine if bankruptcy is the best option..... many bankruptcy attorneys have consumer counseling agencies that they work with, the bankruptcy trustees select the agencies that are accredited to perform this service for those who file in their jurisdictions.
only an attorney can assist him now, he has let things get to far out of hand. if he ends up filing for bankruptcy the trustees may order the cars sold but he needs to allow the legal process to unfold now, since he failed to deal with these issues sooner........
the trustees office will have a list of agencies and will also have a class that he will have to attend after the chapter is actually filed.
This is great that you are figuring these things out at a younger age. I didn't determine that I wanted to go to law school until I about graduated from my undergrad university. International law is a great field.
1st thing first. When you go to college, you might want to consider getting a bachelor's degree (4years to complete it). Most law schools will tell you that no degree is better than another. Here are some degrees you could considering studying in college: Business, Economics, Pre-Law, Political Science, History, English, Philosophy, or Accounting. You might want to consider learning a second language, as international lawyers work with foreign nations.
Depending on which state you want to live in will depend on what the law school in that state will offer. You do not HAVE to have a masters degree or a PhD to be an international lawyer. It may help you educationally, but I doubt it is required.
I do not care to help you any further. Just let me know, and I will see what information is helpful!
