Watta satta
Watta satta (Urdu:وٹہ سٹہ), literally give-take, is a form of bride exchange that is common in Pakistan and Afghanistan.
Watta satta involves the simultaneous marriage of a brother-sister pair from two households. In some cases, it involves uncle-niece pairs, or cousin pairs. This form of marriage in Pakistan is typically endogamous, with over 75% marriages involving blood relatives, and 90% of the watta satta marriages occurring within the same village, tribe or clan (jaat, biraderi).
