You must not be a lawyer. I am a lawyer who did exactly that. Up until a couple of years ago I was admitted to practice in two states. I did absolutely no legal work in one of those states and had to spend $500 per year for fees and attend twenty-four hours of continuing education each year at a cost of nearly $1,000 to keep my license there. There was no reason for me to go through that if I had no use for the license. I can reinstate it at any time simply by notifying the bar and paying a reinstatement fee. Lawyers giving up their licenses without any compulsion to do so is routine.
You gave up your entire law license(s)? Or just the states you no longer worked in?
Isn’t it true that you can optionally give up your license before it is taken away from you for cause?
Somehow I don’t think $500 is going to be a problem for her
