Hello. Your solicitor will need to fill in some standard forms for the buyer's solicitor, and this will require you to disclose the works. I expect your lease will entitle you to demand copies of the relevant paper work, but even if it doesn't the council should send it to allow the sale to go ahead. Personally, I'd contact the council now, to ask for copies, ax if you leave it to your solicitor, it may delay matters.
Disappointing answer. We are marketing our property with full disclosure about underpinning. The council (our freeholder) has a long history of ignoring our written and/or verbal requests.
As a leaseholder we evidently have no rights about getting documentation, but can only hope we can get it.
Thanks. I'm afraid that whether or not you can force the council to cooperate depends on the terms of your lease. I'm sure your solicitor can check this. However, I suggest that to save time, you ask for the information now. Your solicitor can always chase them up if needed. Also, it's a bit off the normal path, but as it's a council, you could always request the information under the Freedom of Information Act, and they are obliged to respond within 21 days.
