If you send in 10.00 a month while you are in law school, the 400 debt will be paid by the time you graduate. But, the debt is not a serious problem. You tend to confront authority figures. And, while questioning authority and testing the rules is a lawyer-like trait, you will need to control yourself in class, or you won't even get to the character/fitness phase. Go ahead and apply. There are practicing attorneys out there with felony convictions. Some have been in jail for being in contempt. One guy attending law school here in Tampa has a child for whom he pays child support, but has no interest in seeing. Not all law students or graduates are angels. You can get all that childhood stuff sealed/expunged. You can be your first case.
12 years old? I'm not sure all the juvie stuff is an issue. Not too many 12 year olds actually get arrested. Email the bar examiners, under a pseudonym if you must, and ask.Most states require adult convictions to be disclosed, expunged or not. But juvie? I suspect not. A $400 debt is a problem? Seriously, you can handle that? The military stuff might- Israel or U.S.? Dishonorable?That adage is for trial cases only. Getting something expunged is a matter of filing a single form that isn't even a full page. If you can't handle your own non trial legal issues, maybe you shouldn't handle anyone else's. You can pay someone to file it, but why? I guess maybe if its a state where hounding is required, but still can't you hound on your own? You can negotiate with the collector on your own as well, but its only $400, but you still should be able to handle it offer them $200.
The juvie stuff is in a different category. This is a good question. I do not know if it needs to be disclosed. I can't remember the exact language of all the forms when I filled them out. The reason juvie is in a different category is because you cannot use it to tell any trends. All kids are stupid and make bad decisions.
