IVA and renting

[Littlesunn]

To cut a very long story short, I finally plucked up the courage to tell my emotionally abusive partner to move out with her equally manipulative and lying son who is 24.
After a lot of huffing and puffing she agreed but there is a problem.
Her son took out an IVA last year for debts amounting to around £20k (I think)
They went to look at a house today, but the agents said they may struggle due to her sons credit rating. He apparently has to go on the lease as he is over 18 and will be credit checked.
Am I stuck with them for the next 5-6 years?! I really don’t think my mental health can cope. I own my own home thanks to inheritance and her name is not on the deeds.
Can anyone help? Is this right or is she telling me fibs?

Suggest your ex leases the house in her own. If he moves in later I don't think they can stop it but it isn't your problem

Her son is 24, in the nicest possible way, his mess is not your problem. They need to move out, whether that's together or separately isn't your concern, just give them a deadline, and it definitely won't be 5 or 6 years in the future. House shares aren't credit checked if that's all he can afford

Assuming you are unmarried and the house is either owned or rented in your sole name you simply tell them to leave. If they won't do so voluntarily you change the locks. Not your problem.
