Joint families were the norm but legal separations between brothers and even father and son have been recorded in inscriptions. Women and daughters had rights over property and land as there are inscriptions recording the sale of land by women. The arranged marriage system followed a strict policy of early marriage for women. Among Brahmins, boys married at or below 16 years of age and the brides chosen for them were 12 or younger. This age policy was not strictly followed by other castes. Sati (a custom in which a dead man's widow would immolate herself on her husband's funeral pyre) was practiced but the few examples noted in inscriptions were mostly in the royal families. The system of shaving the heads of widows was infrequent as epigraphs note that widows were allowed to grow their hair but decorating it was discouraged. The remarriage of a widow was rare among the upper castes and more accepted among the lower castes.
