Without the information requested in my previous response, I can only give you a general answer, but I hope this helps.
It is impossible to know what your question is as you have not asked one. If the dispute is over placing a number on the gate, which is being denied, it is unclear why this is an issue unless the gate is not yours to put a number on. If it is your property you are allowed to do as you wish. If it is not your property, then you will have to refrain from placing numbers on there.
If you require legal assistance please feel free to contact one of the organisations below for further assistance.
We are Advocate
They match members of the public who need free legal help with barristers who are willing to donate their time and expertise in deserving cases for those who are unable to obtain legal aid and cannot afford to pay.
LawWorks is a charity working in England and Wales to connect volunteer lawyers with people in need of legal advice, who are not eligible for legal aid and cannot afford to pay and with the not-for-profit organisations that support them.
Law Centres Network
Law Centres deliver advice through lawyers and qualified caseworkers and defend the rights of people who cannot afford a lawyer.
If you want to provide more information to me please feel free to do so, and I will be happy to help but based on the lack of information this is all I am able to provide.
