My state is Massachusettes and I'm looking for some information on squatter rights laws. Here is my situation. I live with my adult children, and they have a neighbor behind them who has been cutting down trees and brush and have had a surveyor come out to survey their property.The surveyor has put the orange stakes assumably on their property line. But they are obviously placed on what my kids have thought was their property. The home has been in my son-in-laws family for about 35-40 years and he has been cutting the grass and has a brick fireplace on the property for all that time. The neighbors want to have a meetting on Tuesday with they surveyor and my kids to talk about the situation. Evidently they want to put up a fence. I'm an ex realtor from NJ and am curious as to the law in Mass. I don't want my kids to go to this meeting without some info on their rights.What is the name of your state (only U.S. law)?
