You can use the RTB’s online portal to submit a dispute application, pay any applicable fee, upload supporting documents and communicate about your case. After creating an account or signing in, check that your contact details are correct and follow the instructions for your dispute type and any evidence deadlines. Keep copies of everything you submit, and check the portal and your email regularly for messages or requests from the RTB. Using the portal does not decide the dispute itself; the outcome depends on the evidence and the RTB’s dispute resolution process.
