GDPR Art.19: Notification Obligation Regarding Rectification, Erasure or Restriction

Keep a proper registry of every recipient you've disclosed personal data to. Link it to your Records of Processing Activities and include who the recipient is, what data categories were shared, when and why the sharing happened, and a current contact for privacy notifications. Update it every time you start sharing with someone new. Create standardised notification templates for each type of change. A rectification notice should include the corrected data. An erasure notice should clearly identify what needs deleting. A restriction notice should spell out the scope and expected duration. Always include clear instructions on what the recipient needs to do. Automate notifications wherever you can, especially for recipients you exchange data with regularly through APIs or data feeds. Set up triggers so that when data is corrected, deleted, or restricted in your system, the relevant notifications fire automatically. For recipients without automated channels, build a manual workflow with tracking so nothing falls through the cracks. Log every notification you send - date, recipient, notification type, and content. You'll need this both for accountability and to answer data subjects who ask which recipients were told. Keep these logs alongside your data subject request records. Put escalation procedures in place for when recipients don't respond or can't action the notification. Your data sharing agreements and processor contracts should require cooperation with downstream notifications and confirmation of actions taken. If a recipient consistently fails to comply, enforce it through your contractual mechanisms.
