Monogamy is the norm, but the wealthy sometimes practice polygyny. The incest prohibition extends to first cousins; more distant cousins may be married only on payment of livestock penalties. Ifugao courtship takes place in the girls' houses ( agamang ). Before a wedding, temporary trial marriages sometimes occur. Wealthy parents arrange marriages through intermediaries, and they make decisions concerning their children's use and inheritance of property. Families exchange gifts and maintain close relations following marriage. Divorce may occur by mutual consent, or with the payment of damages if contested. Grounds for divorce include bad omens, childlessness, cruelty, desertion, and change of affections. There is a vast difference in property allocation if the couple has children. Childless partners each take whatever they brought individually into the marriage through inheritance and then divide commonly acquired joint property equally; if there are children, all property goes to the children. A widow or widower may marry again only after making a payment to the deceased spouse's family; the payment is reduced if the second spouse is of that same family. Postmarital residence is typically close to the largest rice field acquired by either partner, but newlyweds may initially spend some time with the parents of either the groom or the bride. Both sexes may inherit property and debts from both parents, although the firstborn receives the greatest share. An illegitimate child has the right to receive support from his or her natural father's family but no right to inherit from his estate.
