There was a tendency toward endogamy among the kandangyan. Slaves were only rarely kept, most often being sold to lowlanders. There was no hereditary slave class. Monogamy was the normal form of marriage, although polygyny was practiced occasionally by the wealthy. In cases of polygyny, the first wife has higher authority and status than her co-wives.
Marriages are alliances between kindreds.
First cousin marriages are forbidden in both theory and practice, but marriages to more distant cousins can take place, with suitable payment of fines in livestock. Bride-price is present. Residence is left to the personal choice of the married couple and usually results in settlement near the largest rice field holding of either partner. First children tend to inherit irrigated farmland, but otherwise inheritances are divided among all legitimate children. Each kindred is collectively responsible for the actions and welfare of its members.
