Marriage. A couple intending to marry must be from different clan groups, and they must seek approval of their respective district councillors. Most marriages take place in church though today there are a few common-law marriages. Divorce is uncommon, but separation is more frequent, especially for Catholic couples. The birth of a child must be registered if the child is to receive the rights of being Nauruan, even if the birth takes place outside of Nauru.
Domestic Unit. The family unit consists of a wide group of relatives on both the father's and mother's side. Adoption is relatively common, especially by a Nauruan who has no children of his or her own. If accepted by the community, an adopted relative receives the same rights to land and residence as does a blood relative. A Nauruan household is likely to comprise an older couple with one or more married children and grandchildren, for an average size of eight persons per household.
Inheritance. Rights to land, useful trees, goods, songs, dances, and all other possessions are passed on from parents to all children, both natural and adopted.
Socialization. Children are much loved and treated with care and affection by both parents and all members of the Domestic unit. Schooling is highly valued by parents, who may make financial sacrifices to send daughters and sons to secondary schools in Australia and New Zealand. Children are raised to think of themselves as Nauruans and to speak the Nauruan language.
