For the sake of the argument here is one definition:

Article 16 of the Universal Declaration of Human Rights declares that "Men and women of full age, without any limitation due to race, nationality or religion, have the right to marry and to found a family. They are entitled to equal rights as to marriage, during marriage and at its dissolution. Marriage shall be entered into only with the free and full consent of the intending spouses." The Cairo Declaration on Human Rights in Islam gives men and women the "right to marriage" regardless of their race, colour or nationality, but not religion.
