We split 5 years ago. Since then I've been trying to buy him out of our house.
At first he wanted an unrealistic sum for his share. Then, when he got more sensible, he wanted to impose a ridiculous timescale, 3 weeks to get the money and get his name off deeds etc.
Then he got solicitors. In total I had letters from 4 different firms. All invited my proposals for settlement, then never replied. The last firm started court action. That got stayed 2 years ago for us to mediate. We did, it was a waste of time as the mediator was useless.
since then, nothing. I have tried to contact him, asked him what his bottom line is. No reply. Meanwhile he moans to our DC that he has no money and is stuck living with family. But if he took what I've offered he wouldn't be!
