A son is questioning the legality of his mother selling an ancestral property inherited from his grandfather without his consent. While one opinion suggests the sale is illegal as ancestral property devolves on legal heirs, another argues that if the mother received the property from her father, she likely owns it outright and can sell it as she wishes. The key to determining its ancestral status lies in how it was acquired and whether it has remained undivided through four generations of male lineage.
