Polygyny laws around the world

1How to read this comparison

The Shariah basis for polygyny is Surah an-Nisa' 4:3: a man may marry two, three or four, but "if you fear that you will not be able to deal justly, then (marry) only one". This verse gives conditional permission, not a command. For this reason, many modern Muslim countries do not prohibit polygyny but regulate its practice — usually through court permission, notice to the existing wife, or a check of financial means.

In the table and sections below, countries are classified into four models:

• Permitted with permission — a court or official body must approve first (Malaysia, Indonesia, Pakistan, Morocco).
• Permitted with notice/registration — no prior approval, but the wife is notified and may seek judicial dissolution (fasakh) (Egypt, Jordan).
• Permitted with almost no statutory restriction — subject to Shariah rulings and registration (Saudi Arabia, northern Nigeria).
• Prohibited / criminal bigamy — Tunisia, Turkey and almost all Western countries.

3Southeast Asia: the court-permission model

The Nusantara region shares one model: polygyny is permitted for Muslims, but must first go through the religious authorities.

• Malaysia — under the Islamic Family Law (Federal Territories) Act 1984 (Act 303) s.23 and the equivalent state enactments, the court considers whether the marriage is just and necessary, the husband's financial means, his ability to be just, and the harm to the existing wife. Marrying without permission is an offence (Act 303 s.123), although the marriage may be registrable later after penalty. See Polygyny in Malaysia.
• Indonesia — UU Perkawinan 1974 is based on monogamy (Article 3), but the Religious Court (Pengadilan Agama) may grant permission if the wife cannot fulfil her duties, has an incurable disability/illness, or cannot bear children (Article 4), with the wife's consent and proof of means (Article 5).
• Brunei and Singapore — Brunei follows the Syariah court model; Singapore channels applications through ROMM, which interviews both parties.
• Southern Thailand and the Philippines — Islamic family law applies as minority personal law. Southern Thailand is a common destination for Malaysian couples who marry without permission — this is discussed in Marriage abroad.

4South Asia: Arbitration Councils and personal law

Pakistan and Bangladesh still use the Muslim Family Laws Ordinance 1961 s.6: the husband applies to the Chairman of the Arbitration Council, stating his reasons and whether the existing wife consents. The Council — made up of representatives of the husband and wife — decides whether the new marriage is necessary and just. If the husband marries without permission, he must immediately pay the existing wife's entire deferred mahr (dower) and may be imprisoned for up to one year and/or fined; the wife also has grounds to dissolve the marriage.

India is different: Muslims are governed by personal law (Shariat Application Act 1937) with no requirement for statutory permission, while Hindus, Christians and Parsis are bound by monogamy. The state of Uttarakhand enacted a Uniform Civil Code 2024 that prohibits polygyny for all residents, including Muslims; the national debate continues.

5Middle East and North Africa: from notice to prohibition

Arab countries show the widest spectrum:

6Sub-Saharan Africa: dual systems

Many African countries operate a dual legal system: statutory (civil) marriage is monogamous, while customary and Islamic marriages may be polygynous. In Nigeria, 12 northern states have extended Shariah jurisdiction since 1999–2000; Islamic marriages there may be polygynous and are handled by Shariah courts. But a person already married under the Marriage Act (civil) cannot marry again — that is bigamy. Couples need to know the type of marriage they register, because it determines inheritance and divorce rights.

7Western countries: bigamy is a crime

In the UK, US, Canada, Australia and throughout the EU, marrying while still in a valid marriage is the crime of bigamy. There are, however, important differences:

• Limited recognition — the UK and Australia recognise a polygynous marriage that was valid where it was contracted (if the parties were domiciled in a country that permits it) for purposes such as maintenance and divorce, but do not allow new polygynous marriages within the country.
• Immigration — EU Directive 2003/86/EC Art. 4(4) allows only one wife to be reunited; the UK and US have similar restrictions.
• Religious marriage without registration — not counted as a legally valid civil marriage; the wife receives no protection of property or inheritance.

8Lessons for Muslim couples

1. Follow the law of the place where you live. The majority of scholars stress the obligation to honour agreements and to obey regulations that do not command sin (Surah al-Ma'idah 5:1; Surah al-Isra' 17:34). Laws that regulate polygyny do not forbid what is lawful — they set out a procedure.
2. Register every marriage. Registration protects the wife and children; a secret or unregistered marriage runs contrary to the objectives of the Shariah (maqasid) of preserving lineage and property.
3. Use conditions in the marriage contract. The Hanbali school and the laws of Morocco, Jordan and Saudi Arabia allow the wife to stipulate that the husband will not take another wife; the Prophet ﷺ said the conditions most deserving of fulfilment are those by which marriage is made lawful (Sahih al-Bukhari 2721; Sahih Muslim, Kitab an-Nikah). The Shafi'i, Hanafi and Maliki schools, however, hold that such a condition is not binding, although the contract remains valid.
4. Get local advice before marrying in another country — see recognition of foreign marriages.
