Can I write a will in the UAE to override default Sharia inheritance rules?

It depends on your status. Non-Muslims in the UAE can generally register a will directing how their UAE assets are distributed, and doing so is the main way to ensure outcomes differ from any default rules; recognised channels include the relevant courts and dedicated wills registries. For Muslims, faraid (the fixed Sharia shares) governs the bulk of the estate, but Islamic law allows a limited bequest to be made by will to non-heirs within recognised limits, while the fixed shares for qualifying heirs cannot simply be cancelled. A registered will can also be important for naming guardians for minor children. Because the rules differ sharply between Muslim and non-Muslim estates, and the registration options and any limits are set by the courts and applicable laws, you should confirm what is permitted for your situation before drafting. A clear, properly registered and, where needed, translated will reduces disputes later. You can compare verified UAE legal professionals on LEXAI to draft and register a will that is valid in the UAE.
