My question involves a consumer law issue in the State of: MA
The Background:
I own a house that I rent out.
The house shares a driveway with the neighboring house.
The driveway had deteriorated pretty badly, and a big pot hole had formed this spring on my side of the driveway.
I decided to replace my side of the driveway instead of patching it.
I contacted my neighbor to see if he wanted to do his half at the same time
He said no, that he didn't have the money.
Instead, he, without my permission, filled in the pot hole.
A week later, my paving contractor came and re-paved my half of the driveway.
The problem.
The neighbor now want me to pay for the work that he did, filling the pot hole
As leverage, he is claiming that the contractor strayed several inches onto his side of the driveway when he was doing the paving, and is threatening to sue me if I don't pay for the patch
My question:
If the paving contractor did stray, who is liable - me or the contractor?
also, this is not the first time the neighbor has done work on my property without my permission - last year, one of his tenants had backed into my house, damaging the siding. I asked him to pay for it. But instead, he replaced part of the siding. (the color was not a good match, and he replaced an undamaged section as well)
