Chris - I’m afraid it’s not good news as the application has been cancelled. It turns out it was the incorrect application as submitted as a claim as to registered land when the land is actually unregistered
The second issue is crucial as well as it appears the claim is only for the last 9 years. The minimum is 12 years. The cancellation explains this to the conveyancer and they will need to review matters and submit a fresh application if able to do so
Your Qs re options may now be relevant and worth discussing with your own conveyancer - if the seller can’t meet the legal requirements then another option may exist. That might include a statement of truth re their 9 years plus an indemnity policy to insure against someone else registering the land. Something to perhaps consider but as posted previously whether that’s doable will be down to your mortgage lender, your conveyancer and you, in that order usually.
