This is a precedent set of optional sub-clauses for integration into provisions relating to arrangements between a controller and processor where one of the parties is required to appoint a representative under data protection law. They are suitable for use where a counterparty is required (or may be required) to designate a representative under Article 27 of the United Kingdom General Data Protection Regulation (UK GDPR), Assimilated Regulation (EU) 2016/679. As explained in the drafting notes they may also be adapted for use in controller to controller or sub-processing arrangements, or for use in arrangements to which the EU’s General Data Protection Regulation (EU GDPR), Regulation (EU) 2016/679 applies.
