Jo, It is roughly 2 acres with no planning permission so agricultural value would be about £12,000 I think.
I do not haver access to this land as there has been someone using it for more than 10 years, openly and without the consent of the deceased owner. So presumably they are the only party who can benefit from this doctrine of adverse possession?
This was where I started. Having traced her she said she was "not interested" in anything to do with (strangely) this so I then asked you what my next course of action was which I think you have answered perfectly. I will talk to the occupiers & go down this route.
Jo, I will draw up an agreement between us beforehand so that i don't end up doing all the work and then finish up empty handed. I will get an ADV1 form as you suggest. Can you tell me how I pay you please as I don't need a subscription for more. I now have a clear plan & am happy.
