My sister and I have been left some money by an aunt. Years ago she had a son who was adopted, and he now says he’s going to contest the will. Has he the right to do this?
No. As long as he was formally adopted by the other family he will have no claim on his natural mother’s estate – unless for some reason she was supporting him financially at the time of her death. Adoption severs the blood tie in law. He would have a potential claim on his adoptive parents’ estate.
