Hi Delboy,
I'm kinda in a similar position. I 'sold' my house 3 months ago but the buyer's solicitor wrote back with 2 whole pages of questions relating to the 'file.' The original solicitor I used to purchase my house didn't, to put it politely, do a good job.
My current solicitor is a friend. On the plus side, he's not going to charge me a fortune but, on the downside, he won't help me to get compensation from the original solicitor.
I'd be grateful if you could keep us informed on your progress. It sounds like I'm a month or so behind you.
It's really annoying that one pays 'professional fees' to one's own solicitor, the bank's solicitor and land registry fees and this sort of thing still happens. My solicitor didn't think it was unusual at all. His feathers did get a bit ruffled when I commented that solicitors buy standard contracts and a checklist from the Law Society!
