Use your personal referral network
Family members and good friends who have a DUI or DWI arrest, or who have friends in the legal system, can tell you about qualified DUI attorneys they know.

Require The DUI Attorney to provide references and experiences
You need a DUI attorney with actual court room experience. Like any other legal charge, drunk driving is highly technical. Don’t be afraid to ask potential DUI attorneys how many cases drunk driving cases they’ve successfully litigated.

Shop locally, Your Hometown DUI Attorneys have more court connections
Look for DUI or DWI lawyers in your town or city. Again, a good friend from out of town might be a fine lawyer…but does he know and understand the local laws? Does he have practice in applying those laws in court? If not, you’re better off saying, “Thanks, but no thanks.”

Beware big promises!
Be on your guard against a criminal lawyer who promises the moon. The simple fact is, you cannot always get off without a conviction. A good DUI attorney will be honest about your chances.

Interview Your DUI Attorney to make sure You Understand Everything! Communication is Critical!
A DUI defense attorney needs to answer your questions. A lawyer who consistently rephrases your questions in order to give you easy answers is not a lawyer with your best interest at heart. If you feel you’ve been left in the dark, do not hesitate to fire your lawyer and find another.
