Both grandparents had one will. One died a sibling got the survive to write new will that put her in and made a friend executor, attorney with POA

I'm sorry to say that there's no question in your post, so I can't be sure what you actually want to know. But I'll try to provide some general information that might fit. It is possible to do a joint Will in Georgia (one where more than one person signs the Will as his or her own Will and it provides for what happens at each person's death). However, they are not favored under Georgia law, and, unless the people who wrote it also signed a separate contract that bound each of them to abide by the Will and not change it in the future, a joint Will only becomes binding on the first person who passes away, at his or her death. The surviving person is completely free to make a different Will and change the estate plan. If your grandmother had a joint Will with your grandfather (I'm assuming she survived him), then most likely she was completely free to change it and do a new Will after his death. It's very rare to see a joint Will at all, much less one that is accompanied by a separate contract to make it binding on the survivor. The question is likely not whether the original Will should still be respected. From your post, it sounds like you are concerned that someone manipulated the surviving grandparent into benefitting her over other heirs, and that there was perhaps some other wrongdoing. Unfortunately, this kind of forum is not suited for providing actual advice regarding a particular case. If you believe that your grandparent was manipulated into signing a Will that she didn't really want to sign, or if you think that there was financial abuse by a Power of Attorney agent or anything similar, all you can really do is to hire your own attorney, provide the attorney with as much information about the situation and any documents as you can, and let the attorney help you figure out if you have any ability to complain. You should look for an attorney with experience in estate planning, elder law, or trust and estate (sometimes called fiduciary) litigation. Best wishes to you.
