My question involves a right of way to a lake in the state of New York:
There is a deeded right of way between my cottage and a neighbor's cottage, leading to the shoreline. Just learned that my neighbor built his dock on part of the right of way. Only a few feet of his dock are on the shore (right of way). Obviously the rest of the dock extends into the lake, which I believe falls within the public domain. However a third party has a deeded
right to use this right of way (like to put in his boat there).
Question: If this third party learns that my neighbor's dock (only a few feet of it) is built on part of this right of way, does he have a legal right to demand the dock be removed?
Many thanks for any guidelines you can give me here.
