What is Ejari and how much does it cost to register?

Ejari is RERA's mandatory tenancy-registration system; every Dubai lease must be registered to be legally valid. You need it to set up DEWA, process visas, get internet, and file any rental dispute. Registration costs roughly AED 155-220 in government fees (about AED 177.75 online via the Dubai REST app; around AED 219.75 at a trustee centre); agents charge more (verify current fee).
