In the Charlotte area, the firm with the reputation of being aggressive is James, McElroy and Diehl:

However, if I could give some advice from someone who has been there, done that. Divorce is very expensive. The aggressive firms don't come cheap. You can spend hundreds of thousands of dollars fighting with each other and at the end of the day, the only ones who come out ahead are the attorneys. Make every effort to come to common ground and save your dollars for something productive.
If you absolutely cannot resolve your differences without an attorney, then please use an attorney within the county where your case will be heard. This will save you a lot of money, because they can pop in and out of the courtroom and only bill you for the time spent in your case. If you bring someone in from outside your county, you will be billed for the whole day...even if your case does not even get heard that day.
This is advice I wish someone had shared with me as a friend to someone going through a tough divorce. Courts are very crowded, and they don't truly have time to listen to you squabble over who is the bigger Jack Ass. Find a mediator, work through the issues, and move on.
