How to manage bad neighbours
Seeking legal advice
If your Insurance Cover isn't available for legal help and costs then you will need to get advice from a Solicitor. Keep in mind you might not be eligible for legal advice and help and it could well turn out to be a expensive exercise.
However, most Solicitors operate a 20 minute free legal advice scheme, so use it if you can!
One letter to a problem neighbour might do the trick, but you need to know your rights and what to do if anything happens. If you can avoid a legal battle then please do so at all costs. It is both very costly, very stressful and could cause permanent damage to any ongoing neighbour relations. If the situation warrants it and you have exhausted all the options, all else has failed, then you are unfortunately probably left with no alternative.
Police Involvement
Any problems or incidents then ring the Police. Always contact the Police on 999 if you or others are in danger or feel unsafe.
Explain the situation to the Police, ask for the Officer or Clerk you speak to for their names and details and log this in your diary. Request that the Police attend for the purpose of speaking to your neighbour(s) and taking whatever action might be appropriate. A verbal warning might be enough, and with 3 of these, you may be able to instigate proceedings under the Protection from Harassment Act 1997.
Ask for a Community Officer to be assigned to you and to call round for an informal chat about the problem you're experiencing. Your Police Force should by now have in place some specific procedures and policies for dealing with NFH. If not then ring your Police HQ and ask to speak to a Senior Officer about it and find out what their specific policies are.
