Hmmm an attorney who cant spell whoda thunkit
Have the stickers re-made and say "In My Opinion" and then have the builders name with the slash through it. If you caveat it or preface it by saying its your opinion, then its not libel or slander-At least that is what I was taught in my basic business law classes-and the instructor became a judge so I figure its probably right.
Then you can tell the attorney two things:
1) how to spell libel,
2) and to pound sand.
Just my humble opinion,
