DP discovered this evening that SD13 is left home alone regularly by her mum for several hours at a time into the late evening, and has been left overnight on occasion in the past. This evening, SD is home alone, and her mum is not available by mobile phone - and SD had no details of neighbours or other relatives that she could contact. The only instruction SD was given by her mum was what time to go to bed. DP has told her by phone to call him if she needs to.
DP doesn't know if SS8 has been left in his sisters sole care in the past - SS is currently with us.
What, if anything, can DP do?
There is a Court Order placing residency with their mum, and a contact order in relation to SS, but only a recital regarding SD.
