There is no separate Galway tenancy tribunal: disputes covered by the Residential Tenancies Act are generally handled nationally by the Residential Tenancies Board (RTB). You can apply through the RTB’s online dispute-resolution service, usually choosing mediation or adjudication, and should provide the tenancy agreement, rent and deposit records, messages, photographs and a clear timeline. The outcome depends on the evidence and facts of the individual case, and some decisions can be appealed to a tribunal. RentWise is independent information, so consider contacting Threshold, Citizens Information or a solicitor for guidance, and check the RTB’s current procedures.
