Ireland does not currently operate a separate national deposit-protection scheme, so the RTB does not hold or automatically return deposits. First, ask the landlord or letting agent in writing for the deposit and request an itemised explanation, keeping the tenancy agreement, messages, photographs and receipts. If the issue is not resolved, you can apply to the Residential Tenancies Board (RTB) for dispute resolution, where mediation or adjudication may be available; the outcome depends on the evidence and facts of the tenancy. If a licensed letting agent is involved, you may also contact the Property Services Regulatory Authority about possible professional misconduct.
