Robert and Stanley held legal title of record to adjacent tracts of land, each consisting of a number of five acres. Stanley fenced his five acres in 1989, placing his east fence fifteen feet onto Robert's property. Thereafter, he was in possession of this fifteen-foot strip of land and kept it fenced and cultivated continuously until he sold his tract of land to Nathan on March 1, 1994. Nathan took possession under deed from Stanley, and continued possession and cultivation of the fifteen-foot strip that was on Robert's land until May 27, 2014, when Robert, having on several occasions strenuously objected to Nathan's possession, brought suit against Nathan for trespass. Explain whether Nathan has gained title by adverse possession.
