Hello, welcome to the website. My name isXXXXX can assist you with this.
On what basis has he put a fence up on your property? Does he say he is entitled to do this for some reason?
Okay. Do you want to force him to remove it from your land?
Are you there?
:) Good. Okay.
Okay. You have a surveyors report on this?
Do you want him to be forced to remove the fence?
Okay. Then you would need to issue a claim in the county court, using a Part 8 Claim Form, and attach to that a witness statement setting out the detail of which land you say is yours (using the surveyors report) and ask the Court to order that he remove the fence and stop trespassing on your land.
This can be a tricky thing to start on your own without professional help, because the claim form has to be sent with a detailed witness statement, which would be your evidence in court proceedings later on.
Then you should ask the surveyor to help you do that. he can draw up the relevant letter easily with the information he already has from the survey and your instructions so far.
Where in the country are you?
