DEAR ABBY: When my husband, “Sid,” was a young adult, his mother died by suicide. A few years later, when his maternal grandparents died, his mother’s two siblings inherited his grandparents’ estate. Other family members have commented that it seemed wrong for Sid and his sister to be disinherited from their mother’s share of the estate. Because Sid and his sister were young adults, they didn’t have enough confidence or support to question their aunt and uncle. Their father was out of the picture.
