A child, let's call him Pete, went to some medical treatment when he was younger than legal age (18).
All documents about this treatment were sent to his parents.
Pete is now (way) above legal age.
The documents are still in (physical) possession of his parents.
- Are the parents allowed to use or publish these documents? (against Pete's will)
- Can Pete ask (demand) the parents to hand these documents over to him?
- Get hold of at least a copy of these documents.
- Prevent use (disclosure) of these documents by the parents in any legal process (at court).
