Do muslims get married without dating
Most countries around the world have laws that set a minimum age of marriage.
Religious marriage recognizes and creates the rights and obligations intrinsic to matrimony before that religion.
In Niger, where the age of legal marriage for girls is 15, 76 per cent of girls are believed to be married before their 18th birthday.
Girls Not Brides' executive director, Lakshmi Sundaram told : "A range of international treaties and conventions point to the need for setting a minimum age of marriage of 18.
In countries like India, where the legal age for marriage is 18 for women and 21 for men, the person who was a minor at the time has to file a complaint to get the marriage annulled. In 2013, the country had an estimated 10m women aged 20-24 who had been married before they were 18, according to US Council on Foreign Relations.
According to the campaign, Girls Not Brides, one in three women in the developing world are said to be married before they turn 18.
Pluralistic legal systems may prioritise customary or religious law over national law, exceptions may be granted upon parental consent or authorisation by the court and law enforcement officials maybe poorly trained or lack awareness of the minimum age of marriage.
