Re: Water and Sewer Line on Our Property
You would need to do considerable research to determine how the lines ended up where they are. I suspect that a single parcel, which the house was part of, was split to create the 4 individual parcels involved but that is only a guess.
What I am suggesting is that the utility lines were put in with permission from somebody. As such, there was no easement required and basically, any subsequent purchaser of the property would simply have to accept the encroachment. If that is the situation, if you want the lines moved, the cost would be yours.
So, given the possible costs involved, you might consider hiring an attorney that can do a title search and investigate how the lines ended up where they are. If there is no inherent right to be where they are, you could conceivably demand the owner pay for the relocation but in all honesty, I suspect there is a valid justification for lines being where they are which would mean you pay to move them if you want them moved.
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
