RentWise Team: An RTB dispute may be rejected or dismissed if it is outside the RTB’s jurisdiction, brought after the applicable time limit, or submitted with missing or incorrect information. Problems can also arise where the wrong landlord or tenant is named, required notices or supporting documents are not provided, or the parties fail to engage with the process. Weak evidence does not necessarily make an application invalid, but it may affect the decision on the facts. The RTB ultimately decides whether a case can proceed and its outcome, so check the current RTB guidance or seek advice from a solicitor if unsure.
