Today I got my requested packet from the California State Bar on resigning my membership. Mostly it consisted of dire warnings about how difficult it is to regain membership (almost as difficult as getting it in the first place, but not quite) and how their inactive bar dues ($115 a year) are really quite, quite reasonable all things considered, since you enjoy all the benefits of being a member except being allowed to practice law. (I'm not sure what those other benefits were, except getting the very dull bar journal and having a little card to carry around.)
I still plan to resign. I never was all that interested in practicing law (as opposed to theorizing about law, which fortunately doesn't require a license). California is a nice place to visit, but I wouldn't want to live there. And $115 a year to keep a token membership seems too high. I'll keep my Washington license, which ought to cover me if I ever get an unforeseeable urge to turn back into a lawyer.
It feels kind of weird to toss out something I worked so hard for, though. Now that pretty license is just a wall decoration.
