My sister's neighbor is putting up a spite fence, more like a wall. She has been a very difficult neighbor for a long time--wanting my sister's twin teen daughters to "hang" with her young daughters. She was very insulted when the girls said they'd be happy to babysit for them, but didn't really want to hang with them. The woman was ok when she was married, but now she is divorced with a new live in who has had words with sister's hub. Bottom line: They are going to build this wall unless sister/hub can stop them. Hub/Sister are planning to divorce and want to sell the house (which is in an exclusive neighborhood). The neighbors know this. Sister is afraid that the value of her house will dive, since anyone moving in would be unable to take down the wall. Any suggestions? They are getting a lawyer, but aren't sure it will happen in time.
