Some people do but usually the "have your lawyer" phrase means "find a lawyer who specializes in this area and contact them". Still, the point still stands, it's expensive and time consuming to even begin the process of engaging an attorney if you haven't done so before.
Say "have a lawyer" instead of your lawyer would convey that point without that baggage of someone sounding like they don't understand that most people don't already have a lawyer in the same way they have a dentist.
