Am I being naive?

[RunAwayKey]

Surely in situations where an abusive father is given supervised contact, this is in no way enforceable if the primary carer is convinced any contact will add to the harm inflicted on the children?

The penalties of not complying are a fine, community service or imprisonment, none of which relate to or force the children to go to contact, and residency being changed option isn't possible when a child isn't safe with their father, which would be the only enforcement option which actually forces the child to go to contact with the abuser.

Or am I missing something here?

Surely the fact that it is supervised contact should be in order to protect the DC? (Although if I was the RP, I would be tempted to run away with my DC rather than subject them to further risk.)
Will this be in a contact centre? If so, discuss your concerns with the staff as they will have experience of similar situations and may be able to advise you.

If the rp is in prison, the child will be in care, and the carer will comply with the contact order. Pretty obvious I'd have thought.
