Is it true that lawful heirs and assigns of the data subject may invoke the rights of the data subject?

The assertion is true because, under many data protection laws, the rights of the data subject can indeed be invoked by lawful heirs and assigns. This allows for the continuity of rights after the data subject's passing, ensuring that their personal data remains protected and their interests are represented.

This approach recognizes that the legal rights associated with personal data do not automatically terminate upon the death of the individual. Lawful heirs and assigns can engage in actions such as requesting access to personal data, making objections to processing, or seeking rectification or erasure of data, akin to the rights the deceased would have exercised.

It's important to note that this is often contingent upon specific legal provisions and may vary depending on the jurisdiction. However, the general principle supports the notion that the rights over personal data can extend beyond the life of the data subject, ensuring their privacy preferences continue to be respected even in death.
