Some countries do not recognize locally performed religious marriage on its own, and require a separate civil marriage for official purposes.
Conversely, civil marriage does not exist in some countries governed by a religious legal system, such as Saudi Arabia, where marriages contracted abroad might not be recognized if they were contracted contrary to Saudi interpretations of Islamic religious law.
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.
These changes included giving wives legal identities of their own, abolishing the right of husbands to physically discipline their wives, giving wives property rights, liberalizing divorce laws, providing wives with reproductive rights of their own, and requiring a wife's consent when sexual relations occur.
These changes have occurred primarily in Western countries.
Historically, in most cultures, married women had very few rights of their own, being considered, along with the family's children, the property of the husband; as such, they could not own or inherit property, or represent themselves legally (see for example coverture).
In Europe, the United States, and other places in the developed world, beginning in the late 19th century and lasting through the 21st century, marriage has undergone gradual legal changes, aimed at improving the rights of the wife.
This forced Gough to disregard sexual access as a key element of marriage and to define it in terms of legitimacy of offspring alone: marriage is "a relationship established between a woman and one or more other persons, which provides a child born to the woman under circumstances not prohibited by the rules of relationship, is accorded full birth-status rights common to normal members of his society or social stratum." Economic anthropologist Duran Bell has criticized the legitimacy-based definition on the basis that some societies do not require marriage for legitimacy.
He argued that a legitimacy-based definition of marriage is circular in societies where illegitimacy has no other legal or social implications for a child other than the mother being unmarried.
In terms of legal recognition, most sovereign states and other jurisdictions limit marriage to opposite-sex couples and a diminishing number of these permit polygyny, child marriages, and forced marriages.
Over the twentieth century, a growing number of countries and other jurisdictions have lifted bans on and have established legal recognition for interracial marriage, interfaith marriage, and most recently, gender-neutral marriage.
In countries governed by a mixed secular-religious legal system, such as in Lebanon and Israel, locally performed civil marriage also does not exist within the country, preventing interfaith and various other marriages contradicting religious laws from being entered into in the country, however, civil marriages performed abroad are recognized by the state even if they conflict with religious laws (in the case of recognition of marriage in Israel, this includes recognition of not only interfaith civil marriages performed abroad, but also overseas same-sex civil marriages).
