During the winter neighbour's tree blew over and damaged 2 fence panels between our gardens. They never came round as I expected, so a few days later when I saw them in the street I suggested we would go halves, if they would use their van to pick them up (6 x 6 needed, and we don't have a van). I just wanted it fixing quickly and it seemed a neighbourly thing to do.
Nothing happened, next time I see them, I apologise for bringing it up again but asked what was happening. Apparently landlord is ignoring her messages.
A couple of months have passed. Tonight I ordered some fence panels and paid for delivery. Would I be unreasonable to just place the remains of the broken panels in her garden?
(Other relevant facts - They don't care for their garden, some wood is not going to spoil the look. We have 2 large dogs to contain. The ownership of the fence is lost in time, with the previous owners we just went halves).
