The document discusses the concept of unobstructed heritage under Mitakshara law. Unobstructed heritage means that sons, grandsons, and great-grandsons acquire inheritance rights in ancestral property by birth alone. Their rights are not obstructed by the existence of the property's owner. Only for sons, grandsons, and great-grandsons is ancestral property considered unobstructed heritage. All other relatives have only obstructed heritage, meaning the owner being alive prevents them from having interests in his property.
