Would you please tell me what form(S) I must initially file for an Adverse Possession Claim and how long I have to file it after my neighbor hired a surveyor to come out and put property stakes in my lawn? The stakes were put in last Thursday, August 9, 2012. I have maintained, mowed the property for 25 years. I know in Pa one must do so on a continuous basis for 21 years without interruption. I was told I only have a week from the time the stakes were put in. If so, I must act immediately. I really need to know if this is something my wife and I can do ourselves or whether we must have an Attorney? We do not have one! Thank you!Richard
