Under Article 11 of the Kuwait Civil Code, your legal domicile is the place where you habitually reside — in practice, your primary residential address in Kuwait. This is the address courts and government bodies will use to serve legal notices, correspondence, and judgments on you.
If you run a business, trade, or practice a craft in Kuwait, Article 12 adds a second layer: the place where you carry out that commercial activity is also considered your domicile for matters relating to that business. So a landlord or supplier could validly serve you at your business address for trade-related disputes, even if your home address is different.
For expats, it is important to keep your civil ID address and any registered business address up to date. If you choose a specific address for a particular legal transaction (for example, in a contract), that is known as an elected domicile under Article 14, and it must be agreed in writing. Courts will use that address for all matters connected to that specific contract, which is why it is worth reviewing address clauses carefully before signing.
This is general legal information, not legal advice. For advice on your specific situation, consult a lawyer licensed in Kuwait.
