Of the three bonded (non-"athi") classes, royal bondsmen and religious bondsmen were hereditary while private bondsmen were not. A private bondsman's servitude to his patron stood until his debt was fully repaid. A bondman's obligations ceased with death, and could not be perpetuated down to his descendants. On the other hand, royal servicemen ("kyundaw") were hereditary, and were exempt from personal taxes in exchange for royal service. Similarly, religious servicemen ("hpaya-kyun") were hereditary, and were exempt from personal taxes and royal service in exchange for maintaining the affairs of monasteries and temples. Unlike royal servicemen or even "athi" commoners, the religious bondsmen could not be conscripted into military service.
