Usually, each side pays its own legal or other representation costs in an RTB dispute, so you should not assume that the other party will reimburse you. You can represent yourself, although legal advice may be useful where the issues are complex or the potential financial consequences are significant. Any power to make a costs-related direction depends on the RTB procedure, the parties’ conduct and the facts of the case, and is ultimately for the RTB to decide. Check the current guidance on RTB.ie or speak to a solicitor before incurring substantial costs.
