Gate from neighbour into my land

There is a small pedestrian gate from my neighbours onto my land.
Would this be a problem legally if I were to be absent and neighbours entering my block when I am absent.
Adverse possession etc

 

How long are you planning to be absent from your property?

 

This is how WW2 started. Someone left the gates open and Germany took the opportunity. If your neighbor has a bad mustache, be on the lookout.

 

We could be away a year

 

Does the gate open your onto your land or in the other direction?
You can block it, lock it, or seal it up.

 

You can put a lock on your side

 

Its not a right of way or any such legal impediment ? Just a gate ? Remove it, replace it, lock it, grow plants over it. Its your fence.
Adverse possession wont occur with a gate. That suggests each lot is fenced off from the other. However if the person continues to be given a right of access they could seek to assert your removal of access in some situations (eg they have no other access). They may also be a concerned as you. Have a chat and ask if they mind you closing up the access.
