Read the RTB correspondence carefully and note the hearing date, submission deadlines and any instructions for joining. Check the notice of termination and gather your tenancy agreement, rent records, messages, photographs and other evidence relevant to the dispute. Prepare a short timeline of events and a clear response to the landlord’s claims, then submit documents to the RTB by the stated deadline. Attend the hearing or contact the RTB promptly if you cannot do so. For guidance on your individual circumstances, consider contacting Threshold, Citizens Information or a solicitor; the RTB will decide the dispute based on the evidence and applicable law.
