I need to contest a will in Georgia and I live in Pennsylvania.

If the Will has already been admitted to probate and an executor appointed, you can't contest the Will. However, what you can do is take steps to ensure that the executor is doing his or her job correctly and, if necessary, you can try to have the executor removed and someone else appointed.  If it's a Georgia estate, you will need an attorney licensed in Georgia. Your residence in Pennsylvania should not be a problem; most attorneys are perfectly capable of working with a client located in another state on estate matters. For the situation you describe, you should find an attorney who works with estate and probate matters and that does dispute resolution work. You may need full-blown litigation, so you might want to focus on attorneys who have that experience. Find an attorney and contact the attorney's office to schedule a consultation. The attorney should be able to give you a better idea of what to expect and whether you have a case worth pursuing after you've had the consultation.
