Can I appoint a guardian for my children in a UAE will?

Yes. Non-Muslim parents can appoint guardians for children under 21 through a DIFC guardianship will - available as a standalone will without registering a full asset will. You can name an interim guardian (a Dubai-based adult who takes custody immediately if both parents die) and a permanent guardian who may live abroad. Provisions apply to minors habitually resident in Dubai or RAK.
