I had to see a judge and when I got up there, I asked him to take off one of the names at the last minute (I had added two middle names to keep a family name and at the last minute decided I only wanted 3 names instead of 4). There wasn't any problem; he just took it right off. It had already been in the newspaper I'm pretty sure. But if the matter's already settled court wise, you'll probably need a do over.
Of course, the adding of a name may be a different matter than dropping one. But it's worth a shot. Just ask.
