Tree on property line (grew through fence)

[Onyedika On]

Hello BP,

I have a situation where a tree on the property line may need to come down. The fence that also separates my property from my neighbors runs right through the tree (or more accurately the tree grew through the fence). The tree definitely predates me, and by the size, possibly the neighbor as well. From a responsibility standpoint, who "owns" the tree and thus cost to cut it down? Is it a shared responsibility?

Thoughts?
