Global Legal Status of Polygamy
Polygamy is legally permitted in 58 countries as of 2025, mostly in Africa and parts of Asia, where civil or religious law allows a man to have multiple wives under specific conditions. The majority of these nations are in sub-Saharan Africa, including Nigeria, Kenya, and Uganda, where customary or religious courts recognize polygynous unions alongside civil marriage. In the Middle East, countries like Saudi Arabia, UAE, and Iraq allow Muslim men to take up to four wives under Sharia-based family law, subject to judicial approval and financial disclosure. In contrast, most of Europe, the Americas, and East Asia prohibit polygamy entirely, treating it as a criminal offense or voiding any such union under civil code. For a detailed list of countries and their specific legal frameworks, refer to the latest reports on international family law compiled by legal research organizations and policy institutes.
Polygamy is also practiced informally in countries where it is not legally recognized, often through religious or customary arrangements that lack state registration. In India, polygamy is permitted for Muslims under personal law but banned for Hindus, Christians, and other religious groups, creating a patchwork of legal status across the country. In the Philippines, the Muslim Mindanao region allows polygamy under the Code of Muslim Personal Laws, while the rest of the country prohibits it under the Family Code. In Australia, polygamous marriages performed overseas are not recognized, and bigamy is a criminal offense, though some communities continue informal multi-partner arrangements. In the United States, polygamy is a felony in all 50 states, but Utah reduced penalties in 2020 for cohabiting families, effectively decriminalizing private, non-licensed plural relationships while still prohibiting multiple marriage licenses.
Countries Where Polygamy Is Most Common
Polygamy is most prevalent in West and Central Africa, where countries like Burkina Faso, Mali, and Gambia report that over 30% of married women are in polygynous unions, according to demographic and health surveys. In Nigeria, polygamy is widespread in the northern states under Sharia law and in customary systems in the south, with estimates suggesting that nearly one in three married women are in polygynous households. In Indonesia, the world's largest Muslim-majority country, polygamy is legally allowed for Muslim men with court approval, and it is more common in rural areas of Java and Sumatra. In Saudi Arabia and other Gulf states, polygamy has declined in practice due to economic pressures and changing social norms, though it remains legally permissible for Muslim men with the condition of equal treatment and financial support.
In terms of global rankings, the countries with the highest polygamy rates are concentrated in sub-Saharan Africa, with Burkina Faso, Mali, and Gambia consistently topping surveys on marital practices. In Asia, polygamy is most common in Afghanistan, where it is permitted under Islamic law, and in rural areas of Pakistan and Bangladesh, though precise figures are difficult to verify due to unregistered unions. In the Middle East, polygamy rates have fallen sharply in countries like Tunisia and Turkey, where family law reforms have restricted or banned the practice. In the United States, while polygamy is illegal, the Fundamentalist Church of Jesus Christ of Latter-Day Saints and other groups continue to practice it in compounds in Utah, Arizona, and Texas, with enforcement varying by jurisdiction and often focusing on fraud, abuse, or underage marriage rather than the mere cohabitation of multiple spouses.
Legal and Social Implications of Polygamy
Polygamy raises complex legal issues around inheritance, child custody, immigration, and tax benefits, as most modern legal systems are built around the assumption of a single-spouse marriage. In countries where polygamy is legal, courts often require a man to obtain consent from existing wives and to prove his financial ability to support multiple families equ
