Hello my name is ***** ***** I will help you with this.
When you say who is at fault do you mean the neighbour or the agent please?
Who actually owns that bit of land?
Ok - so is it their land?
Ok - You do need a surveyor who should give you an expert report.
The expert report should indicate where the boundary is and also whether it is true.
If it is not then sadly you have to move it. If you do not the neighbour could take you to Court and seek a declaration as to the true boundary
But if the expert report is on your side then of course you do not need to do anything, you can simply rely on it
So the surveyor report is absolute key
Its not a criminal offence here it is a civil dispute between the parties
But you want to avoid Court where possible
I would suggest using mediation instead if there is any form of dispute
Can I clarify anything for you about this today please?
