Back in March we had a bad storm and the fence at the back blew down. My neighbours, neighbour had taken down all 3 fences at the same time too so when our fence went, our dog could roam 5 gardens. Asked neighbour if she wanted to halves on a new fence at the back. The deeds dont confirm who owns the fence. She agreed to pay half, we booked the cheapest guy after getting 3 quotes. The day before new fence was due to go up she came and said she wanted a different style to what we planned, couldn't afford to help after all unless we wanted to just repair the two panels that had blown down. The rest of the fence was in terrible condition so repair was a no. We appreciated she might not have the money and offered her to pay half in instalments. I had been on maternity for a year, so didnt have the money either, but it had to be sorted. Gave her my number as we were heading out to my daughters first birthday party. The fence went up the next day and she text again, not paying for the fence I will contribute towards what it would have cost to repair. I replied politely saying the fence was beyond repair and the total costs to replace was £900 including disposing of the old fence. I said pay what you think is reasonable. Later on in the month I saw that she had paid £100 in my bank account.
This week she text to say I'm putting a retaining wall at the back, with a fence on top - am I ok to use the fence posts? I said no politely. Just been out in the garden and saw that she has had someone dig all the ground up her side of the fence. She has dug under our fence at least a foot. All the ground around our concrete footings is gone. Can she do this? Im worried our fence may become unstable?
