We used to live in California where we had a big Cottonwood tree in the back yard. It was about 5-6 ft. from the back fence where our lot bordered another persons back yard. A few years ago the people behind us put in an in-ground swimming pool that also came about 6-8 ft. from this same fence.
The person that lives there came over one summer day while we were packing to go on vacation and said that the tree was dying and losing its leaves and they are making a mess in the pool. I told her that it was not dying and that type of tree is the first to lose its leaves each year and all the other cottonwoods around town are doing the same thing. Also we were going on vacation and I would see her after we got back. After vacation I didnt go over there and never her from her anymore. This past summer we sold the house and moved to another state. The Realtor said this neighbor has talked to the new owners and the tree is raising the concrete by the pool and that they want something done. The new owners didnt know anything about this and want us to do something. Are we responsible for having the tree removed and any repairs, even though the tree was there LONG BEFORE the pool???
