I have this contact information:
"Thankyou for your email you can call us on 0300 303 0648."
Thanks, I have only just come off the phone from them after twenty minutes. The caveat was in place in July, probate was granted in September. The person at the probate office said I would have to get a solicitor involved, because she cannot give any more information or tell me how the caveat was bypassed.
As I suspected, the laws in rhis country are deeply flawed.
