Alternative Dispute Resolution

Law No. 144/2015 of September 8 establishes the principles and rules to which the Alternative Dispute Resolution Entities (RAL) must comply.

The diploma applies to procedures for the out-of-court resolution of national and cross-border disputes promoted by an ADR entity, when they are initiated by a consumer against a supplier of goods or service provider and respect contractual obligations resulting from purchase and sale contracts or provision of services, entered into between suppliers of goods or established service providers and consumers residing in Portugal and the European Union.

Thus, in compliance with the obligation imposed by this Diploma, Década informs consumers and other stakeholders in the business activity that, in the event of a dispute, the consumer may resort to an Entity for Alternative Dispute Resolution for consumer disputes.

The Directorate-General for Consumers publishes the list of Alternative Consumer Dispute Resolution Entities (RAL) that were communicated to the European Commission, according to paragraph 2 of article 17 of Law nº 144/2015 of 8 September, amended by Decree-Law No. 102/2017, of August 23.
