“We now come to consider the second question, namely whether under Native Law and Custom of the Onitsha people a wife of the deceased member of a family could become the owner by virtue of long possession of the property of her deceased husband, which she occupied with the knowledge of the family, or by adverse possession? It would appear that the essence of possession of the wife in such a case is that she occupies the property or deals with it as a recognised member of her husband’s family and not as a stranger; nor does she need express consent or permission of the family to occupy the property so long as the family make no objection to her occupation.”
