For most private residential tenancies in Kildare, a deposit dispute is dealt with through the Residential Tenancies Board (RTB), rather than a separate county process. First, ask the landlord in writing for the reason for any deduction and keep the tenancy agreement, payment records, photographs and messages. If it is not resolved, you can apply to the RTB for mediation or adjudication; mediation is voluntary, while an adjudicator considers both sides’ evidence. The result depends on the individual facts, so consider getting guidance from Threshold or advice from a solicitor if the amount or circumstances are significant.
