My parents purchased their land in 1961 and have a deed and survey from that transaction. The land has not been surveyed since, and no one even thought about the property lines, until my father passed away in 2010. A few months after the funeral, my mother began probating the estate (no will) and was advised to get a new survey to add to her deed. In the process of surveying, we discovered that the land markers were in a totally different place than they were during our childhood. My mother informed us that in 2006 her neighbor talked privately with my father and convinced him to move his cement post corner markers (we're not sure what he told my dad). The neighbor then had a new survey done and, bingo! he gained 3/4 acre of land along the property line. The neighbor now says, "Sorry, I have a survey showing the land is mine." Please tell me this is fraudulent.
