I guess folks just roll with it, rather than being like 'nope, I'm takin' ya money. Bye!'
It's not quite that simple, they can be moved in 'exceptional circumstances' but there's some handwaving there.
Plus most people are trading up and need the sale to go through or they can't afford the place they're buying and would therefore be likely to lose more in their deposit than they'd gain from receiving the deposit on their place. Then you've got all of the unrecoverable costs (solicitors fees, surveys, removals, etc) on top of all of that.
It's usually the one that initiate the balls up that ends up paying for the additional costs associated with a supplemental contract. Obviously it's easier if the chain is short.
So, the buyer's solicitors and the phantom 'servers down':
They were definitely lying. Bastards. Now had notification from the lender that the buyer had incorrectly filed their Nominated Legal Advisor paperwork. (Again). So this caused delay. Now hoping for completion today or tomorrow.
