I'll give you the short version.
The house my ex lives in is jointly owned by me. We are currently going through court to sort this out. He has a lodger because he can't afford the mortgage on his own. I have no issue with him taking a lodger as it's in my interest for the mortgage to get paid.
However, I know nothing of this lodger except his first name. My ex and I are on very bad terms so when I asked for more info he ignored me. I asked him to get a DBS check done on him but he said no. He said he had a "fit and proper person" check done due to his job but didn't provide details when I asked. He says he knows this guy from work but he never mentioned his name when we were together and he lied to me about how he met a previous lodger (who had a DBS so I wasn't worried about) so I can't trust what he says. The room he is letting out has been advertised online so this lodger could be anyone for all I know.
All my attempts to find out more have been ignored. He won't even tell me his last name.
My children spend 5 overnights a fortnight at this house with this unknown lodger, and I know from my eldest daughter (who is 5) that he does interact with my kids and play with them etc, which I'm not happy about, but haven't said anything.
It's not that I'm certain this guy is a danger to my girls but I am very unsettled with him having potentially unrestricted and unsupervised access to my children.
AIBU to want to know more about him and to get the relevant checks done to keep my girls safe? Since he won't give me any info about him what do I do?
