A homeowner obtained a large plot of land and moved onto the land, occupying a significant portion of the property. The homeowner lived on that portion of the land for more than 22 years, believing that the whole plot was his own. Recently, however, the homeowner learned that the deed that he had acquired was in fact defective. Now, a person with a valid deed is claiming the entire plot of land for himself. The statutory period for adverse possession in this jurisdiction is 20 years. What rights, if any, does the homeowner have with respect to the plot of land?
