Frequently Asked Questions

Q: Does sending an email with client personal data to a US law firm constitute a cross-border transfer requiring SCCs?
Technically yes, if the data relates to EU residents and the US firm is not covered by an adequacy mechanism. In practice, law firms rely on SCCs embedded in engagement terms or data sharing agreements. Firms should review whether their standard client engagement documentation and vendor contracts address this.
Q: Are SCCs automatically sufficient, or is additional analysis required?
SCCs are a necessary but potentially insufficient safeguard. Post-Schrems II, firms must also conduct a transfer impact assessment evaluating whether the law of the destination country — particularly government access rights — undermines the protection that the SCCs are meant to guarantee. --- *Last reviewed: 2026-05-19 by LawyerAI Editorial Team.*

A cross-border data transfer occurs whenever personal data is moved from one country to another, including through remote access, cloud processing, or API calls to servers abroad. Under GDPR, transferring personal data outside the EU/EEA is restricted unless the destination country has been granted an adequacy decision by the European Commission, or an approved transfer mechanism — most commonly Standard Contractual Clauses (SCCs) or Binding Corporate Rules — is in place. The 2023 EU-US Data Privacy Framework provides an adequacy basis for transfers to certified US organisations, though its continued validity is subject to legal challenge.

Every time a lawyer uploads a document containing personal data to a cloud-based AI tool hosted outside the EU, a cross-border data transfer may be occurring. Firms must map these data flows, ensure appropriate transfer mechanisms are in place with each vendor, and document their legal basis. The absence of a valid transfer mechanism is a GDPR infringement that can attract significant fines and reputational damage.
