neighbor want to replace fence, no issues with my fence

[Ron Singh]

Hi

my neighbor contacted me with his plans to replace fence

, however there is no issues with the fence common to my and his home, and I don't see any reason to spend unnecessary 3k to replace something which has no issue.

there might be issues with his other side of fence, I have no idea, as his house is behind mine.

how would you handle the situation ?
