Dear [name of attorney],
I was recently charged with driving while intoxicated. This happened at [location] on [date, time].
Although I had alcohol in my system, I do not believe the charge is warranted.
I'm seeking a free consultation for legal help. If you do not provide free consultations, would you be able to provide the name of a lawyer who does?
Thank you for your attention in this regard.
