Dubai's Rental Disputes Center (RDC) has set out a principle that could reshape how landlords and tenants challenge tenancy contracts: a lease can be annulled, even after it has been signed and is already running, if one party is later found to have concealed or misrepresented material information when the deal was struck.

The ruling grew out of a specific dispute. A landlord leased a property to a company, only to later discover that the same company had a history of rulings against it in other rental cases for failing to pay amounts owed on units it had taken to sublet. Armed with that discovery, the landlord applied to the RDC to have the lease annulled rather than simply suing for unpaid rent.

The center grounded its decision in the UAE's Civil Transactions Law, holding that the duty of transparency between contracting parties is not limited to the moment of signature. Information that would have changed a landlord's or tenant's decision to enter the agreement — such as a prior record of unpaid rental judgments — can be raised even after the contract takes effect, and can be enough to unwind the lease entirely rather than just support a damages claim.

Property lawyers in Dubai describe the ruling as a signal to both sides of the rental market. Landlords, they say, now have stronger grounds to vet a prospective tenant's or sub-lessor's dispute history before signing, while tenants and leasing companies should be aware that withholding a problematic financial or legal record can expose them to having an active lease thrown out entirely, not just to a financial penalty.

The decision adds to a broader push in Dubai to tighten transparency rules across the rental sector, as the emirate's population and rental demand continue to grow.
