Ex and I bought house in 2005. Ex put in £15k deposit. Had doc drawn up by solicitor to say deposit was put in by him. Married in 2009 so doc void due to marriage. I put in £3-4K towards home furnishings etc upon moving in.
When ex made redundant in 2012 I gave him £3k to set up own business.
Ex left me in 2014, I stayed in house with DS. I work pt so we agreed to pay half mortgage each so he still had investment. He Also paid above what child maintenance calculator should be, but not excessively.
Between ex moving out in 2014 and end of 2019 I spent approx £8k on home maintenance and improvements. So add up all I've put in over the years id say it matches the £15k deposit he put in.
Moving forward to end of 2019 and I am in a position to buy him out. Had valuations done and he insisted he was due half of the £80k equity. He refused to get legal advice but i did and was told half was too generous. But to avoid conflict I gave in and transferred £35k and verbally agreed to pay £2.5k at a later date when I could afford to.
In the meantime a major roof issue and damp issue comes to light which I wasn't aware of when agreeing a figure. This is not new damage and I'm kicking myself for not having a survey done when agreeing to give him half the equity (solicitor didn't advise me to?) as this is going to cost me £3-4K to fix so would have meant his equity figure would be less.
I have asked if he is willing to call it quits at £35k but he is not agreeing that this is fair even though it means he will have ended up with more than half his share of equity. In fact he believes he should be receiving £40k because of the original £15k he put into the house and refuses to acknowledge I have matched this over the years. He says I am deceitful and have lied through my teeth about things which I haven't at all. He has not paid me any CM since March. He is self employed so wasn't working for 2 months but he has been back working since May, had the government bailout and also the £35k in his bank. He is refusing to pay anymore CM until my "debt" of £2.5k is paid off. Where do I stand in all of this? Have I been unreasonable? I genuinely am not someone trying to screw someone over, I thought I'd been very fair over the years but he is now dragging my name through the mud and painting a very bad picture of me. He is also extremely angry because when I first said I was buying him out I was going to rent the property and move in with my DP. However when the roof and damp issues arose I decided I want to sell instead as it put me off being a landlord of such an old property. He thinks I've been deceitful about this but I don't see what it has to do with him if I buy or rent as he would have got the same amount of equity?
