Could you please let me know if the land in question has been fenced in by you/forms an integral part of your property?
Thanks for your reply and apologies for the delay.
The reason I was asking if you had incorporated this land into your property, is that in order to be successful in claiming possessory title, you must show that you have possessed and maintained the land to the exclusion of others. As the land is on the other side of your boundary fence, I can't guarantee that you would be successful in your application, but if you wish to apply, you will need to instruct a local Conveyancing Solicitor, who can take you through the necessary Land Registry application Form and procedure (basically, you need to show that you have possessed the land for over 10 years (if the land is registered) or 12 years (if the land is unregistered), and set out the facts of your possession/maintenance. Once your application has been received, the Land Registry's Surveyor will then come out and inspect the land.
Your Solicitor is likely to charge you £600-£750 plus VAT for this work and the Land Registry fee will be £80.
I hope this assists and sets out the legal position.
