The Convention on the Elimination of All Forms 
of Discrimination against Women:

Adopted in 1979 by the UN General Assembly, is often described as an international bill of rights for women.  Consisting of a preamble and 30 articles, it defines what constitutes discrimination against women and sets up an agenda for national action to end such discrimination. 

Article 16 states that "states parties shall take all appropriate measures to eliminate discrimination against women in all matters relating to marriage and family relations and in particular shall ensure, on a basis of equality of men and women:  a) The same right to enter into marriage, and b) The same right freely to choose a spouse and to enter into marriage only with their free and full consent.”
