Will my home country recognise a UAE civil divorce for non-Muslims?

A UAE civil divorce is generally capable of recognition in the UK. English law recognises an overseas divorce obtained through court proceedings where it is valid in the country it was granted and at least one spouse was habitually resident, domiciled or a national there — conditions a long-term Dubai resident filing through the UAE courts will normally meet. So the outcome you fear, divorced here but married at home, is unlikely if the divorce is done properly and documented. The more important point for you is financial: recognition of the divorce does not shut the door on English financial claims. English courts retain the power to grant financial relief after an overseas divorce in appropriate cases, which matters considerably when there is property in both countries — where the finances are resolved can affect the outcome more than where the divorce is granted. Practically: obtain the final judgment with full attestation and certified translation, keep evidence of your UAE residence, and take advice in both jurisdictions before you file anywhere, not after. Coordinated advice from a UAE lawyer and a UK family solicitor at the outset is the safest way to protect assets on both sides.
