Our house was built in the 80's and had a firewall/back fence before an empty lot. recently someone bought the lot and had it surveyed and built a house.
Our old wall is leaning over(part of it) over the neighbor's lot. They are claiming that the wall was over the property line and yet when we ask for proof (they wouldn't present it a geodetic survey) and change their stand that the wall poses a threat and we are "obligated" to have it fixed.
the question is, do they have the right to force us to have the wall removed or fixed if it isn't crossing over their property line? (which I believe they don't but wanted to be sure) and if it is still within our property if it poses a safety issue is it our responsibility to have it repaired?
