My question involves real estate located in the State of: Washington
I'm sure the answer is going to be "See an attorney" but I'll ask the question anyway.
Nighbors planted 3 pine tress about 30 years ago. The current neighbors are not the original homeowners.
These trees were planted on their side of the property line, about 3 feet from the property boundary.
These trees were planted on a small rise (about 4' feet) so the roots can't extened in one direction (i.e. there isn't much support on the side facing their house). Over the years the trees grew and began to tilt toward our house. These trees are now about 50' high (or higher) and about 20" at the base. The center of gravity is moving toward our house and it's just a matter of time till they fall. A good wind might be all it will take.
Cutting everythng that extends over the line, might ordinarily be the option but cutting will damage (or even kill) the tree. About 3/4ths the way up the tree, the trunk is actually now on our side.
1) Is there any way to force the homeowner to remove the tree?
2) Can they be made liable (by advance warning), if the tree falls onto our house?
