Conversely, such practices may be outlawed and penalized in parts of the world out of concerns of the infringement of women's rights, or the infringement of children's rights (both female and male children), and because of international law.
In developed parts of the world, there has been a general trend towards ensuring equal rights within marriage for women and legally recognizing the marriages of interfaith, interracial, and same-sex couples.
These trends coincide with the broader human rights movement.
Marriage can be recognized by a state, an organization, a religious authority, a tribal group, a local community, or peers. When a marriage is performed and carried out by a government institution in accordance with the marriage laws of the jurisdiction, without religious content, it is a civil marriage.
In some areas, child marriages and polygamy may occur in spite of national laws against the practice.
