RentWise Team: A landlord can bring an RTB dispute about rent arrears, but they must generally follow the required arrears and termination-notice procedures before seeking possession. Keep records of payments, bank statements, messages and any disagreement about the amount claimed, and respond promptly to RTB correspondence. You may be able to use the RTB’s dispute resolution service to explain your position or agree a repayment arrangement, but the outcome depends on the evidence and the individual tenancy. Check the RTB’s current guidance or speak to a solicitor if you have received a formal notice.
