Expatriates marrying in the UAE must navigate a complex set of rules, including different processes for those marrying under civil or religious law, and additional steps for those from different nationalities or with a Muslim partner under Sharia Law. The procedure involves checking eligibility, gathering documents like passports, medical tests, and single status certificates, and registering the marriage at courts or embassies. Post-wedding, the marriage requires attestation by the Ministry of Foreign Affairs for international recognition.
