Our neighbour is currently building an extension to his property which may be too close to our boundary. We are in the UK at the moment and received an email from him last weekend informing us that he had taken down the boundary wall between our properties because it was "ugly". We are left without any means of preventing people and annimals from having access to our garden and property. Does anyone know how we can find out exactly where the boundry is and who owned the wall? If it was his wall is he obliged to re-instate it? Also what course of action might might be open to us if, for example he has moved the boundary onto our land. He made it quite clear that he wanted to acquire some of our land in order to expand his garden however as we only purchased our house recently we advised him that we would need to give our plans for the garden some further thought and get back to him, we have since decided to retain our land. Many thanks in anticipation of any help or similar experiences.
