What happens if a landlord raises rent without giving 90 days' notice in Dubai?

If a landlord in Dubai does not give the required advance notice before changing the rent, the proposed increase generally cannot be enforced for the upcoming term. Under the tenancy law (Law No. 26 of 2007 as amended by Law No. 33 of 2008), any change to the rent or other contract terms must be agreed between landlord and tenant at least 90 days before the contract expires, unless both parties agree otherwise. A late notice, such as one served only weeks before renewal, typically means the tenancy renews on the existing terms and rent. This notice requirement is separate from the amount limit: even with valid notice, any increase is still capped by the RERA rental index sliding scale in Dubai Decree No. 43 of 2013. So a late increase can fail on timing alone, regardless of the figure. Keep dated copies of all notices to prove when (or whether) notice was given. If the landlord insists on the increase, you can raise the timing defect at the Rental Dispute Center under Dubai Land Department. You can compare verified UAE tenancy lawyers on LEXAI to confirm whether the notice was valid.
