If you are accused of committing a crime, charged with DUI, or part of a law suit, you definitely need a lawyer. You should contact a lawyer right away, especially if there are witnesses and/or evidence to gather. A lawyer can also help you avoid legal problems, as well. Some of the things you may want to ask the lawyer when you talk over the phone or meet include:

How much experience do you have with legal issues similar to mine?
How recently have you handled a case like mine?
How was it resolved? (Went to trial, settled out of court, etc.)
What was the outcome? (Did you win the case? Did you lose?)
