Ok, thanks. You should tell Land Registry that you object to the registration on the grounds that you are in adverse possession of part of it. If it has enclosed by you and used as part of your garden for more than 12 years, without the landowner's permission your claim is very strong.
Hello. With unregistered land, the period for adverse possession remains 12 years. With registered land, it's 10 years, even if it was unregistered when your possession started. with that in mind, it might actually be unwise to object to the registration. if the registration goes through, you could then apply to claim the land you occupy on the grounds of adverse possession for ten years. However, you might have an argument if the owner objects.
