I am in a semi-detached property and share a gutter with the neighbour next door. However we are not on speaking terms given that they have caused alot of issues in the past (with me having to appoint lawyers and surveyors and police).
Is there anyway to compel them to share the cost of these works?
As it is on a 4 storey building, scaffolding will need to be erected so the cost is c£700.
