Overview: Why These Rules Matter for Expats
Kuwait's family law is rooted in Islamic jurisprudence (fiqh) and applies to all marriages conducted within Kuwait. Even if you are a non-Muslim expat, certain provisions — particularly those governing interfaith marriages — may directly affect your ability to marry in Kuwait. Understanding what is and is not permitted can prevent serious legal complications.
Permanently Prohibited Marriages: Blood Relations
Under Article 13, a man is permanently forbidden from marrying women related to him by blood in the following categories:
- Direct ancestors: Mother, maternal and paternal grandmothers, and all further ascendants.
- Direct descendants: Daughters, granddaughters, and all further descendants.
- Siblings' descendants: Nieces and their descendants, no matter how remote.
- First-degree descendants of grandparents: This includes aunts (father's sisters, mother's sisters) but not their children.
Permanently Prohibited Marriages: Affinity (Marriage Relations)
Article 14 prohibits a man from marrying certain women related to him through a former or current marriage:
- Any woman who was married to one of his ancestors (e.g., his father's ex-wife, grandfather's ex-wife), regardless of whether that marriage was consummated.
- Any woman who was married to one of his descendants (e.g., his son's ex-wife).
- The mother or grandmother of his current or former wife, even if the marriage was never consummated.
- The daughters or granddaughters of a wife with whom he has actually consummated the marriage. If consummation never took place and the marriage ended, this prohibition does not apply to her daughters.
Prohibition by Illegitimacy
Under Article 15, a man is forbidden from marrying his direct descendants born outside of marriage (zina), no matter how many generations removed. However, beyond direct descendants, no other relatives by way of illicit relations are subject to marriage prohibitions.
Prohibition by Breastfeeding (Rada'a)
Articles 16 and 17 establish that the same prohibitions that apply by blood also apply through breastfeeding, with the same rules about affinity by marriage extended to milk relations. For the prohibition to apply, the breastfeeding must have:
- Occurred within the first two years of the child's life.
- Consisted of at least five certain and full feedings (not casual or partial).
This rule is particularly relevant in Gulf societies where wet-nursing was historically common and can have unexpected legal consequences for families.
Interfaith Marriage Prohibitions
Article 18 contains the most significant restrictions for expats:
- A Muslim woman cannot marry a non-Muslim man, under any circumstances. This prohibition is absolute and cannot be overridden by agreement or foreign law.
- A Muslim man may only marry a woman who is Muslim, Christian, or Jewish. Marriage to a woman of any other religion (e.g., Hindu, Buddhist, atheist) is not valid under Kuwaiti law.
- A person who has converted away from Islam (murtad) — male or female — cannot enter into any valid marriage, even with a non-Muslim partner.
Practical note for expats: If a Muslim man wishes to marry a non-Muslim woman who is Christian or Jewish, the marriage may be conducted in Kuwait, but he should still verify how this will be recognized in his home country and ensure proper documentation.
Temporary Prohibitions
Some marriages are forbidden not permanently but temporarily, until specific conditions are resolved:
Marriage to a Currently Married Woman
Under Article 19, a man cannot marry a woman who is already married to another man or is in her waiting period (idda) following a previous marriage.
Combining Incompatible Women (Article 20)
A man cannot simultaneously be married to two women who would be forbidden to marry each other if one of them were male. The most common example is two sisters — a man may not be married to both at the same time, even during an idda period.
Polygamy: The Four-Wife Rule and Its Restrictions
Kuwaiti law permits a Muslim man to have up to four wives simultaneously, but imposes important legal limits:
- Under Article 21, a man may not marry a fifth wife unless one of his existing marriages has been dissolved and the ex-wife's idda (waiting period) has fully expired.
- Under Article 22, if a man has divorced a woman three times, he cannot remarry her unless she has:
1. Married another man in a valid marriage. 2. That marriage was actually consummated. 3. She has since divorced or been widowed from that man. 4. Her idda from that second marriage has fully expired.
The Corruptor Rule (Article 23)
A man who caused the breakdown of another man's marriage — for example, through seduction or interference — cannot subsequently marry that woman unless she first returns to her original husband, who then divorces her or dies.
Practical Advice for Expats
- Muslim expat women must understand that Kuwaiti law categorically prohibits them from marrying non-Muslim men while in Kuwait, regardless of their home country's laws.
- Non-Muslim expats should verify whether they can conduct their marriage through their home country's embassy in Kuwait, which may apply different legal standards.
- If your religion, nationality, or marital history places you in one of the prohibited categories, do not assume that a marriage conducted informally or abroad will be recognized in Kuwait.
- Polygamous marriages involving expats can create serious legal complications in countries where polygamy is illegal. Consult a lawyer in both Kuwait and your home country before proceeding.
- Always confirm the status of any previous marriages or divorces before entering into a new marriage in Kuwait, as violations of these rules can result in the marriage being declared void.
