There is no separate Kilkenny deposit dispute scheme: disputes are generally handled through the Residential Tenancies Board (RTB). First, ask the landlord in writing for an explanation and keep the lease, payment records, photographs, messages and receipts as evidence. If you cannot resolve the issue, either party can apply to the RTB for dispute resolution, usually through mediation or adjudication, with a tribunal process available in some circumstances. The outcome depends on the facts and evidence, so consider getting advice from a qualified housing adviser or solicitor and check the latest process on the official RTB website.
