Bahrain is a relatively liberal country in the Middle East, but it still adheres to certain conservative norms and values. In Bahrain, it is illegal for unmarried couples, including expatriates, to live together in the same accommodation.
Bahrain's legal system is based on Islamic law, and cohabitation outside of marriage is not recognized or permitted. Authorities may enforce this law, especially if there are complaints or concerns from the local community.
It is essential for expatriates and foreigners planning to live in Bahrain to be aware of and respect the local laws and customs. If you and your partner are unmarried, you should not attempt to live together in the same residence in Bahrain to avoid legal issues.
Keep in mind that laws and regulations can change over time, so it's always a good idea to check for the most up-to-date information from official sources or consult with legal experts or authorities in Bahrain if you plan to move there as an unmarried expat couple.
