Ireland does not currently have a statutory deposit-protection scheme, so a Dublin tenant usually seeks the return of a disputed deposit directly from the landlord first. Keep records such as the tenancy agreement, payment evidence, check-in and check-out photographs, inspection reports, and messages about any proposed deductions. If the issue is not resolved, either party may apply to the Residential Tenancies Board (RTB) for mediation or adjudication, provided the tenancy falls within its remit. The RTB’s decision depends on the evidence and the individual facts, so consider getting independent legal advice for a complex dispute.
