¿Qué es el arbitraje de consumo?

Consumer arbitration is an out-of-court mechanism to resolve disputes between consumers and businesses or professionals more quickly and cheaply than a trial. As a tenant you can use it when the dispute arises from a consumer relationship with the landlord or the building management, provided there is an arbitration system applicable to the case.
