Porperty boundary dispute

[purplemurple1]

My neighbours are claiming they own half a brick shed that is atttached to my property and entirely within my boundary line and have right of access through my back garden. They have put 2 padlocks on the door and are refusing me access to share the shed.
As far as I can tell from the regisrty and the deeds they have no right of access through my garden and the shed is entirely within my boundary. My tennants have been round to ask for a key to share the shed, and later to inform the neghbour they have no right of access and should move their belongings but they (the neighbour) are adamant they own half of the shed and are in the right.

I've posted an earlier thread and have been advised to write to them advising they must remove their belongings by a set date of the will be taken to the tip / put in their garden. Could anyone help me with how to word the letter.

Also is there any legal steps I have to take before removing thier belongings.

thanks

Well thats a turn up for the books they have rang and its sorted. I guess they also looked at the deeds.
