It’s not appropriate, no. Speaking from my experience of having an actual paedophile in the family (two actually 😩) and submitting a Sarah’s Law request.
It only really applies when the person has contact with your child and if you don’t know they are a paedophile. As your mum told you, now you know and the expectation is on you to safeguard your child based on what you know. They won’t release information just because you want to know.
Also, there is nothing that says someone convicted of child sexual offences can’t be around children (unfortunately). Some of them will be placed under a Sexual Harm Prevention Order, which will place certain restrictions on them. One of my family members is not allowed to be overnight anywhere around children. So children’s birthday parties, church picnics, Christmas dinner with the grandchildren, all fine. Sleepovers, not fine. Unless parents of the children meet with his probation officer and explicitly consent. 😳
The other family member though is not under an SHPO and has no restrictions on any contact with children. 🤷🏻♀️ Btw, we are NC with both of them, obviously (but we’re the only ones in the family who are, except the children they abused).
In my experience, it’s very hard to get a Sarah’s Law request through. Even with 2 family members who had contact with my children (unsupervised before I knew), they wouldn’t disclose to me because someone else warned me first and the police said that was good enough and now I knew. Which is bloody stupid frankly. But the scheme is set up to only disclose when there is no other way to prevent close (unsupervised) contact. It doesn’t sound like that’s the case here.
That said, in my personal experience, there are so many of them out there. They are the people you will not expect. You know about this one, so that’s great. Keep your child safe. But it really is the ones without convictions who you don’t know about that you need to worry about. So you need to learn to trust your gut and teach your dc to trust theirs around people and speak up if they feel uncomfortable.
