I was wondering if this matter has been resolved but as there were no responses it is doubtful if MarianneM still monitors the site.
Here is a slightly different situation. In a small block with adjoining courtyards one owner has let a tree (technically a shrub) get out of control and it is now about 4 metres tall and blocks sunlight into our courtyard. The non resident owner refuses to reply to correspondence and is totally non communicative.
Any thoughts anyone?
