    Data Processing Agreements govern how personal data is handled between a data controller and processor under the UK GDPR and the Data Protection Act 2018. A solicitor in this area drafts, negotiates and finalises data processing terms, roles, and responsibilities, including sub‑processor arrangements, data security measures, data breach notification, data subject rights handling, international transfers, and audit access. They also ensure the agreement aligns with tallies of legitimate processing, safeguarding contractual remedies, and the use of standard contractual clauses where required.
