Legal AlertPublic Announcement by the Turkish Personal Data Protection Authority on VERBIS Notification Requirements for Business Partnerships, Consortia, and Ordinary Partnerships

23 March 2026

The public announcement (“Announcement”) issued on 16 March 2026 by the Turkish Personal Data Protection Authority (“Authority”) provides clarification regarding the registration obligation with the Data Controllers’ Registry Information System (“VERBIS”) for business partnerships, consortia, and ordinary partnerships that do not have legal personality.

The Announcement sets out the principles as to which party and in what manner personal data processed within the scope of activities carried out by such structures should be notified to VERBIS.

According to the Authority’s assessment:

  • Business partnerships, consortia, and ordinary partnerships do not have separate legal personality.
  • Therefore, such structures cannot be considered as independent data controllers.
  • Personal data processing activities carried out within these structures must be assessed at the level of the natural or legal persons constituting the partnership.

Approach to VERBIS Registration

The Authority has established the following principles regarding the VERBIS registration obligation:

  • Personal data processing activities must be evaluated separately for each partner forming the partnership.
  • Where the partners jointly determine the purposes and means of processing, this may give rise to joint controllership.
  • In such cases, each partner is required to complete its own VERBIS registration individually.

Key Practical Implications

The Announcement entails the following important practical consequences:

  • A single VERBIS registration made in the name of the partnership or consortium will not be sufficient.
  • Each partner must analyze its own data processing activities and determine whether it qualifies as an independent or joint data controller.
  • It is essential that the roles and responsibilities relating to data processing are clearly regulated contractually.

Action Points for Companies

In this context, companies are advised to:

  • Map data processing activities within partnerships and similar structures,
  • Accurately determine their capacity as data controller,
  • Update or complete their VERBIS registrations, where required,
  • Review and revise data protection provisions in partnership agreements.

Conclusion

The Announcement provides significant clarification in terms of transparency and accountability in personal data processing activities carried out within non-incorporated partnerships. Companies are advised to reassess their existing structures, particularly in light of the practical implications of joint controllership.
