You can generally ask the RTB to withdraw a dispute after submitting it, but you should contact the RTB as soon as possible through your online account or its official contact channels. Whether the withdrawal is accepted, and any consequences, may depend on the stage of the process and the type of dispute. Withdrawal may end the current case and could affect your ability to bring the same matter again, while it may not extend any legal time limits or guarantee a refund of a fee. Ask the RTB to confirm the position, or speak to a solicitor if the issue is significant.
