We've been split for 4 years not long after our youngest was born. We haven't been together since
He had a girlfriend for a year in this time so he'd have evidence of living there (I'm so scared they try to say no you've been together this entire time)
He had to move back in with his mum after he split with his ex. So all his bills etc go there
He is here often to see the kids and stays a couple of nights at his mum. We don't share finances. He paid through child maintenance until last month. We had child maintenance for years probably the entire 4 years.
I have no idea about declaring him living here or if I should? I've never had a partner to even think about this in the past 4 years
I know all his bills etc are registered at his mums house. His car is etc.
I have very nosey neighbours who are out to cause trouble a lot so they will report him staying the night here
What do I do?
