Before applying to the RTB, you can get free information and housing advice from Threshold, Citizens Information or FLAC, depending on your circumstances and availability. The RTB itself provides guidance on tenancy issues and explains its dispute-resolution options, including mediation, which is generally a free and confidential way to try to resolve a dispute. Keep your lease, messages, notices, payment records and photographs, as these may be relevant. These services cannot guarantee an outcome; the RTB decides disputes based on the evidence and the individual facts.
