Thank you very much! I have read ARTICLE 29 DATA PROTECTION WORKING PARTY, WP169 ([LINK MIS TO DAY]: ec.europa.eu/justice/article-29/documentation/opinion-recommendation/files/2010/wp169_en.pdf) reflects on the existence of a common responsibility if it is argued that A gives the purpose, but B accepts them and claims them indirectly (without B, the processing is not carried out because B does not have the coordinates), and A gives the means (including THE TOM), but B could insist that A use certain TOMs to protect the contact data that belong to B. However, if there is only one controller or party third party report or intermediary, should there be only a commercial contract between A and B that grossly guarantees and compliance with the law, and market study participants must agree to submit their B and A data for the purposes mentioned in the contract, and A and B must protect their personal data in accordance with the RGPD, regardless of each other as responsible?

The Commissioner of Data Protection and Freedom of Information Baden-Wuerttemberg provides a guiding light for navigating this world of joint controller agreements-the first model joint controller contract. Developed through collaborations with companies and public authorities, the first model joint controller contract, written in German, provided a beacon of light for many parties navigating the waters of GDPR joint controllership compliance. And now, that very contract is available in English! Dr. Stefan Brink hopes it sheds some light on how to structure joint controller agreements moving forward and brings us all closer to GDPR compliance. Information on joint controllership pursuant to Article 26 (2) 2 of the General Data Protection Regulation (LfDI) In practice, the new legal institute responsible for joint responsibility faces additional requirements for businesses. As part of their projects to implement the DMPR, many companies underestimate the resulting efforts. To avoid fines or possible civil liability, companies must carefully consider whether it is a joint processing, order processing or data transmission to another manager when transferring data to third parties.
