Hello and thank you for your question. I will be very pleased to assist you. I'm a practicing lawyer in England with over 10 years experience.
could she kindly tell me to the best of your knowledge whether your property is registered with the land Registry or whether your property is unregistered? My guess would be, unless your mortgage is very very old, that your property would be registered but you confirmation on this point would be very helpful if you are aware
Sorry for the typo above: "could she kindly tell me to the best of your knowledge..." = "could you kindly tell me to the best of your knowledge..."
