I’ve done a few hundred consultations in my career. I almost always ask about a potential client’s criminal history (sometimes for ticket case I don’t, or sometimes in other consults I forget, it happens). We also have intake forms that ask about your criminal history. Potential clients who have the most criminal history, are often reluctant to explain their entire criminal resume.
They are afraid that I won’t believe them if I know about their past. They want to avoid starting the conversation by telling me they’ve been arrested before, or been to prison before. There is also a weird belief that being arrested for a different category of offense somehow doesn’t count.
For example, I’ve had people arrested for a violent offense who had prior convictions for drugs not tell me because “those were drug cases, this is my first assault.” There is this weird reflex to rationalize not disclosing cases that are in the wrong category of offense. This is your first assault, great, but if you have prior cases for ANYTHING, let your lawyer know.
