There is no separate Waterford deposit scheme: disputes generally follow the Residential Tenancies Board (RTB) process used across Ireland. First, ask the landlord in writing for the deposit’s return and request an itemised explanation, keeping the lease, photographs, messages and receipts. If the issue is not resolved, either party can apply to the RTB for dispute resolution, usually through mediation or adjudication. The outcome depends on the tenancy facts and evidence, and is ultimately decided through the RTB process; consider getting advice from Threshold or a solicitor if the amount or circumstances are significant.
