The Gaddis & some labourer families follows the Batta-Satta system of marriage in which the bride's brother has to marry the groom's sister or vice versa. Batta-Satta is a Barter marriages system for sons to find brides. But every family does not have a girl of marriageable age to exchange; some marry off minors to keep their end of the bargain. Generally in such arrangements two families are involved, that is, a sister of a person is married to another person in lieu of his sister. Sometimes 3 families are involved in this relation.
