I've done some searching and reading of past discussions about fences issues with neighbours and I'm wondering if somebody who had been through this can provide some advice.
Here's the situation: One of my neighbours and I share a driveway. My old neighbour aged out of being at home and one of her older son and his wife have taken over the house. In the backyard, there is a chain link fence that appears to be on the property line. It was probably done a previous home owner and probably on agreement with this guy's mom. That fence basically stops at the back of both of our houses, where the shared laneway starts. There is no issues with that existing fence or it's placement.
