Hi, sorry for the long post. Had a letter from HMRC saying Mr x is linked to my address and need to provide 14 months of bills, mortgage, bank statements, etc. Mr x was my estranged husband. We split years ago following child 1, but did have child 2 a few years later despite not being back in a relationship or living together. I've got all the things together but am now panicked as there are several links to him at my address. My home insurance still has him on, this stupidly was a policy we had on our joint house and when I bought my property 9 yrs ago I just transferred it over. I've actually never reviewed the details and it has automatically renewed yearly ever since, not even had kids on. The insurers have done me a letter to confim this. I've always had x on my car insurance in case needed with kids and took out a second policy for him (as a named driver) when he bought a car but couldn't afford insurance. The car was registered at my address for the insurance. Last year he asked if he could have his bank statements to my address following a disagreement with his parents. I didn't see an issue but when he took out a tenancy agreement later last year it has my address on as his residence, but guess they also did a credit check against my address (didn't know this!). All bills are in my name, it's my house, and I've never had maintenance or sought a divorce, wasn't my priority with 2 children, full time job, etc. Also he has suffered ongoing mental health issues, which is why he left after child 1. He sought help last year for this and we talked about how we could move forward. The doctor is providing a letter to confirm this and the fact that he talked in length about him not living with his children (or me). I have always actively encouraged his relationship with the children, his issues stem from his abusive dad and the reality was he couldn't cope emotionally when his came along. We did have a holiday last year and he paid for himself plus 1 child and I paid for the other, which is evident on my bank statement. I know this doesn't look great but we've never hated each other just underlying circumstances have meant it didn't work as a couple, but the kids love him. I am just really worried about how things will be viewed. I have read that the onus is on me to prove we haven't lived together and while he has wage slips and HMRC letters (tax code, not benefits) to where he lived he has never had any utility bills etc. as he's stayed with friends and family. Has anyone else had a similar situation? Months after him seeking help we have now moved into a house together - I've bought it (in case things don't work) but I added him to council tax, water etc as soon as we moved in and contacted Tax office to advise but before I said anything they advised the letter had gone out to my old address. As we spoke about moving forward together as a family last year would this deem us a couple as there was intent, although he didn't move in and rented miles away due to his new job. Feel so stressed and not sleeping or eating.
