The best thing to do is to call some of the lawyers you are interested in hiring. You should act quickly because you will lose the right to ask for your Administrative License Revocation hearing after 15 days. This hearing can be an important part of your defense. We handle DWIs in Fort Bend, but there are a lot of other good attorneys who do as well. You want to choose the one who seems to be able to answer your questions, has a good reputation and makes you feel comfortable.

Also, this sounds like one of the ever perpetuating rumors that come from within the prison system. Be sure to check with reputable lawyers before you ever give money to ANYONE to try to accomplish something a loved one has "heard about" from other inmates.

His record will likely show all of his criminal history. Whether each of the crimes can be used and how many "points" they will be worth depends on a variety of factors including the type of crime and sentence.

Never assume the PSR writer (who works for the government) got it right.
You need a lawyer. There is a real chance that you could be charged with assault based only on her word. It is possible that the police will want to talk to you before filing charges (or after), and it is much better if you can be prepared and have a lawyer in advance.
You could also go directly to the district attorneys office in your area to try to find out why charges were not pursued. They may not tell you, but it may have been because of incorrect or missing information.
