I actually really like #3. It suits a law office the most. #1 is nice too, but it is not for a law firm logo. #2 looks really cool, maybe you can revise the KLG logo on the left a little. I'm looking for a modern look, but at the same time it has to match a law office.
np, again I really like the logo, so far it is still my favorite. However, if you can add some little changes to it, but not too much to see if it can be better, will appreciate it that.
