For most disputes about a rental deposit, the Residential Tenancies Board (RTB) is the appropriate route rather than the Small Claims procedure. You can apply for RTB mediation or adjudication, and any repayment or compensation will depend on the evidence and the facts of the tenancy. The Small Claims procedure is not generally a replacement for the RTB’s dispute-resolution process in a covered tenancy. If the arrangement may fall outside the RTB’s jurisdiction, check the RTB website or speak to a solicitor about the appropriate court or legal remedy.
