68. Which public authority can help me if I consider that my rights under the Data Act are not respected?

If a Member State designates only one competent authority, this authority will oversee all matters relating to the application of the Data Act. In any event, the name of the competent authorities for each Member State along with the corresponding tasks and powers will be displayed on a publicly available register maintained by the Commission. In case of doubt, applicants can always direct their queries to the data coordinator in their Member State, because it should act as the single point of contact for all issues related to the application of the Data Act. In certain cases, the data coordinator may facilitate cooperation between competent authorities. Natural and legal persons should lodge complaints with the relevant competent authority in the Member State of their habitual residence, place of work or establishment, including with respect to cross-border matters. The competent authorities have a duty to cooperate and assist each other not only within the same Member State but also across borders.
