Yeah, we're on a mile long "access road". Technically, I "own" to the other side of the road, this is for the first 4 houses (including ours). The next 5 houses "own" to the middle of the road.
It is in dire need of grading and more gravel..... I maintain what is in front of our house and one neighbor..... at our expense..... even though there is a 'road maintenance agreement' in the deeds.
The 5 houses past us refuse to pay for anything.... there is a clause in the agreement that liens can be placed against the houses that don't pay..... good luck with that!
The first 4 houses have all agreed to split the costs to repair the first half of the road.... the issue is we have been hesitant to do so, because the back half will have a nice road to use (and drive way too fast past OUR houses) without having to pay (refuse) anything.
The first chance I get, we will be selling this property.
Good luck with resolving your problem......
