RentWise Team: The RTB dispute process is the same in Dublin as elsewhere in Ireland. You can apply through the RTB, usually choosing mediation or adjudication, and should provide relevant documents such as the tenancy agreement, notices, rent records, photographs and correspondence. Mediation aims to help the parties reach an agreement, while an adjudicator considers the evidence and issues a decision; an appeal may be possible through a Tenancy Tribunal in suitable cases. The outcome depends on the facts and evidence, so check the current guidance on the official RTB website or seek advice from a solicitor.
