get an arborist out to lok at the dead tree. then notify your neighbor in writing that it is unsafe. send the notification certified with return receipt. at the same time mail another copy of the letter to yourself, but do not open it. this way if you ever have to go to court you have a copy of the letter you sent him tha tcan be opened by the judge and the postmark will verify the date it was sent.

as far as the roots go, in my area they would be your problem, not his. once it crosses the property line it become your responsibility. rent a trencher and cut the roots on your side.

I am not a lawyer but have seen one on tv...Saw a episode about a tree over hanging someone elses property. Anything above and below your property line is yours to do with as you wish. You should be able to trim and cut roots on your property. If owner is notified of a tree in bad shape and something falls off it its their responsibility. But roots? Call your homeowners insurance see if they have anything to say about it. Agree with previous poster a letter should be sent to document your complaint/request/notification...Maybe he is just procrastinating, also it can be expensive to have trees removed, maybe he can't afford it. Tell him you will call around to get some bids to remove the tree, maybe even offer to help with the cost if he can't afford, be less than pool repair.

Regrettable when these situations arise. You like your pool, the neighbor likes his tree. I have personally removed, at various times, 5 trees (mine) that fell onto houses that I own. My personal residence, completed 3 years ago, has no tree that could hit my house if it fell. Wife likes that idea too.

Just reading through tree problems as I have neighbors who desperately love the look of overgrowing vines everywhere and planting 70' trees on a small beachside property. I live across the street from the beach with fabulous views. Of course, the neighbor planted a 70' tree close to my fence which I will have to pay $500 every two years to trim my side... forever. I am angry that this woman just plants trees like a hippie without taking 5 minutes to research what she's planting on Google. I think it's incredibly selfish. Plus, tons of leaf removal for me and getting pollen all over my black cars that are buttressing the fence where this damn tree is. PS, it also blocks my water view until the winter. Lady... if you want to live in the forest, why don't you? Rant complete!

"Of course, the neighbor planted a 70' tree close to my fence"

Planted a 70' tree?

@millworkman - I know you're trying to be cute. Of course it GREW into that size. Google is your friend; it takes two seconds to research something. I did exactly that when I had Bells Palsy when I was alone and thought I was having a stroke. Anyway, this was fun?
