Jack and Jill were adjoining property owners. Jack claimed that the fence separating their properties was not located properly and that it should be moved back onto Jill's land. Jill claimed that she owned the strip between the fence and the alleged boundary line by adverse possession. She proved that for forty (40) years there had been on the strip in question a barn with a cement floor, which had been built by the person from whom she purchased her land, and that she had been told by the former owner that the fence was the boundary line. The fence consisted of five-foot-high barbed wire set in cement. Did Jill own the strip by adverse possession? Explain by analysis the elements of adverse possession.
