Is an addendum to an employment contract legally binding in the UAE?

Yes — in the UAE private sector, an addendum properly amending a registered employment contract is binding once both parties agree. Under Federal Decree-Law No. 33 of 2021, the contract and its lawful amendments govern the relationship, so a signed addendum varying salary, job title, or working hours becomes enforceable. It should be in writing, identify the clauses it replaces, be signed by both sides, and never reduce protections below statutory minimums — mandatory rights cannot be waived. The MOHRE contract is the reference in a dispute, so an unregistered or contradictory addendum creates confusion; keep signed, dated copies.
