Ex stalling transfer!!

[Beansontoast02]

I have been negotiating with my ex for over a year over our property which we own as tenants in common but still 50/50 as far as im aware. He got a solicitor and threatened to take me to court to force a sale. I made an offer which he verbally accepted but we were then negotiating terms for most of the year. I cant afford a solicitor so am self repping. He said last year (via messages) he now wants more money which I agreed and sent him the agreement to sign with a date it needed to be signed by. It has been 4 months since that date and I have only recieved correspondence asking for proof that the lender will remove him from the existing mortgage. Since this has been provided I have not heard anything from him or his solicitor and am not getting any response to emails or messages.
What is the next step? If he is no longer being represented would the solicitors inform me? I don't want to be accused of harassing him so have only sent him two messages but I want to know what's going on.
I don't want to sell as I live in the property with my husband and very young child..
He is a toxic person and has tried to be as difficult as possible with everything. I'm almost certain he's got a horrible plan up his sleeve despite agreeing to be bought out as he hasn't yet signed any paperwork. I think he's afraid to lose power or something, like he doesn't want to lose the Financial tie, he just wants to make my life difficult because I broke up with him but that was years ago and I'm married with a child now.
This has been going on for years and I just want to cut all ties with him... please help!

A year ago you split with your ex, and now you're married with a child?

Not sure I have any advice, but if my first comment is incorrect, probably an idea to update your post to be clearer

From reading, it sounds like he's waiting for the property to increase. He's sat there, doing sod all and you should be pushing. If I do not here from you on this date...
You need a solicitor before you lose it all.

I wonder if he was thinking you wouldn't be able to afford to buy him out and it would force you to sell/move? Now he's realised you're really in a position to go through with it he's stalling.

I'd send a letter to his solicitor saying that since house prices have dropped over the last 4 months that you're reducing your offer. And if he doesn't hurry up, it'll reduce again.

Are you paying him rent in his share of the property? Who's been paying the mortgage since ex moved out?

@OdinsHorse No, we have been split over 4 years but finally came to an agreement that I would buy him out over a year ago, but have been in disagreement over terms since then.
I reread my post and realised it does sound confusing 😀

@altmember This sounds very plausible! Maybe he's hoping my mortgage offer will run out while I'm on maternity leave and he can try to force a sale again. As he cannot force a sale if I have made a reasonable offer and he hasn't accepted it. But I know he doesn't really want me to have the house as he is really bitter about it all. Do you think I should have the property revalued?
He still has a room in the property which he has kept locked and is just storing stuff in there so we are jointly paying the mortgage.

@B1rd I can't afford a solicitor, I did enquire at a local one and they wanted £500 as a retainer which had to be used by the first invoice! That would not even be enough time to sort this issue out and I just know my exs solicitors would drag it out as long as possible.

You may get more help and responses if you get this thread transferred to legal.

I know you say you can’t afford a solicitor but honestly you need to apply pressure and a solicitor can advise on this.
If he’s paying half the mortgage save this and use it towards a solicitor. You’ll have to pay it anyway (probably at a higher rate if you’re remortgaging) so it should be doable.

I'd get it revalued - as prices are dropping. It might "encourage" him to accept.

If you really can't afford a solicitor, which would be my best advice right now, even in the short term to get things moving, then start applying pressure yourself. His solicitor will be on the the fact your self repping and take advantage of that. Put pressure on, inform yourself as best you possibly can on the law over this. Add to the bottom of emails/correspondence that you would like receipt of your email and a response by close of business on whatever date. Assume confidence and start to push.
