Dad is committing fraud/racking up debt in my name

Le père de l'auteur a accumulé des dettes en son nom sans son consentement, et l'auteur cherche des conseils pour résoudre cette situation.

Hi, this is a throwaway account obviously. My dad previously ran up an income tax bill of 20k in 2016- and instead of paying it, left the UK with me and the rest of the family. We returned in 2021, however instead of paying this bill (which has presumably risen in the meantime), he bought a (worthless) business in my name which is now I have learnt, over 35k+ in debt as he didn’t want to have anything in his name. He is quite emotionally abusive and due to this I have quite bad mental health issues, and I was on and off meds when he presumably got me to sign for this business, which I don’t recall doing, but might well have done. I am deeply concerned about this amount of debt in my name, and I’m wondering if there’s anything that can be done to forcibly potentially remove my name from this business? I would have already reported him to HMRC potentially had it not been for the fact that he put half of the tax bill in my mum’s name- and I don’t want any repercussions on her as she certainly can’t afford to pay it. Any advice would be appreciated!
