What can I do if my tenant doesn't pay rent in Dubai?

If the tenant fails to pay the rent, or part thereof, within 30 days from the date of serving a written notice by the landlord to him to that effect; unless all concerned parties have agreed otherwise. If the tenant subleases the property without the landlord’s written approval. If the tenant uses, or allows others to utilize, the property for immoral or illegal activities. If the tenant causes or allows others to cause damage or changes to the property that endanger the safety of the property. If the tenant uses the property for purposes other than the ones for which it was leased. If the tenant fails to comply with any of the terms of the tenancy contract or the Law within 30 days from date of notice served by the landlord to him to abide by such obligations or conditions. If the property is in danger of collapse. If development requirements in the Emirate require demolition and reconstruction of the property, in accordance with government authorities' instructions. For commercial properties, a landlord may demand eviction, if the tenant has closed business operations for 30 consecutive or 90 consecutive days without giving any valid reasons. In all of the above cases, the landlord has to notify the tenant through the Notary Public or by registered mail.
