Upon the death of a landholder, his land was divided equally among his sons. The sons of concubines, if accepted by the father as being his sons, had the same rights of inheritance as their legitimately-born brothers. The adopted sons of the landholder, if any, could also receive a share of his lands only if the landholder had made specific and public provision before his death, and the extent of land thus received by an adopted son was not necessarily equal to that received by the landholder's own sons.
