Hopefully someone can provide you will fuller answers, but here goes.(posted 8293 days ago)1. Lender Surveys. My experience is that they generally are obliged to get 2, but it is probably covered in the smallprint of your mortgage contract. You can ask for a clearer copy. Your point about the independence of the survey is valid, and they would have to produce the original document in court. The DPA point is crap. It is possible they have contacted the valuers and they have requested anonymity, but you can ask for their identity and write to them directly for a copy of the survey. 2. SARN on Survey. I don't think they can withhold this information from a survey but it sounds like they might try. One for someone else to deal with.
3. Sole liability. It doesn't make much difference in all likelihood as you were probably both 'jointly and severally liable' for the mortgage - meaning that they could opt to chase either or both of you for the full amount anyway. Now you're the only one in the frame, but it doesn't mean you'll end up paying the full amount. It is worth finding out what was taken into account when he declared himself bankrupt.
Good luck
