Rent Dispute Settlement Committees fall under the Abu Dhabi Judicial Department (ADJD) and in order to file a case you need to first visit an Enjaz centre. Enjaz centres are the customer happiness centres for ADJD and provide services like typing and filing cases, receiving court judgements for non-criminal cases, attesting transactions, entering data for court services and notarising public transactions.
If you wish to file a rent dispute case as a tenant, you are required to visit a centre with the following documents and details:
1. The registered lease contract (Tawtheeq)
2. Landlord’s name, mobile number and address.
3. Your Emirates ID and address details.
According to the ADJD call centre – 02 6512222 – once you have submitted the necessary documents and details of your complaint, you will receive a case number within 24 to 48 hours from ADJD.
