I agree with Attorney Rauman. Without knowing the family tree and all of the facts, it is impossible to answer your question. Generally speaking, any Will can be contested. Everyone is entitled to their day in court in the US legal system. The question is whether or not they are likely to win. You have not given us any information to enable us to analyze that issue whatsoever. You need to sit down with an attorney in Georgia and go through all of the facts, as well as providing a copy of the Will.
