Unless they directly and explicitly told you that when you made the Clare's Law enquiry, you are wrong.
The rules around disclosure are very tight under Sarah's Law and it's an entirely separate law. Disclosures (under Sarah's Law at least) are protected under GDPR.
If you enquire under Sarah's Law, you can get one of four results (as explained to us at the time).
No disclosure.
Nothing at all on record.
There is something on record but they won't tell you any details at all.
Partial disclosure - they will tell you the basics but no details.
I forget exactly what the different criteria were for each bit it's basically, there is a conviction but your child is not considered at risk due to their exact age, sex when considered in relation to the nature of the conviction.
ETA: we were told that there is something on the record but we won't disclose anymore than that means literally that. They will tell you they have found 'something' but nothing more than that. The partial disclose was, I think, the 'name' of the conviction and under which law but no further details and just, "Your child is not of an age/sex to be considered at direct risk."
Full disclosure.
All the details because your child could be affected now or in the near future.
It's possible someone could speak to an officer who might take a risk and suggest they do a Sarah's Law too if they've found something and want to give a heads up but they couldn't disclose directly.
One is processed by the DA dept and the other by the CP dept. Completely different police officers, completely different Law.
Even under Sarah's Law, you don't have an automatic right to know the details. They are not just going to drop it in to a Clare's Law 'nothing to disclose' as an, "Oh, by the way..." anymore than they would have told us about a domestic abuse conviction.
It's very tightly protected and regulated.
