RTB mediation is a confidential, voluntary process where a trained mediator helps the parties reach their own agreement, without deciding who is right. Adjudication involves an adjudicator considering the evidence and submissions before issuing a decision, which may lead to a legally enforceable RTB determination order. Mediation is usually more flexible and can preserve the relationship, while adjudication is more appropriate when an agreed solution cannot be reached. The best option depends on the facts of the dispute, and the eventual outcome is decided through the RTB process rather than by RentWise.
