DB bought a house in 2017 for him and SIL to live in. The house is in his name and he pays the mortgage. DB and SIL married in 2019 and separated in Jan 23. They have two DS, 9 and 5. SIL stays in the home currently and has a charge against the property. DB initially wanted her out and didn't see why he should have to give her anything, SIL wanted to stay in the house till DS2 turned 18. DB has now offered SIL 20% of the increased value of the home since it was purchased (about £20,000) and SIL is still adamant that she should live there till DS2 is 18 as she is self employed and doesn't think she will be able to buy a house in the area they currently live.
I suspect they are both being unreasonable. DB can't afford anything, buy or rent, while he is paying the mortgage on his house and I doubt SIL could buy on her own with only £20,000 for a deposit.
They have reached a stalemate. DB currently lives with me and my nephews stay 4 nights in 14. Its not sustainable and I am tearing my hair out as neither will come to compromise and there is no end in sight to my current living situation.
Looking for advice/opinions from other people who have been in either DB or SIL situation. What agreement did you come to? Any solicitors out there who can give me an idea of what DB needs to offer in order to break the stalemate without crippling himself?
