'Exclusive' possession means a claimant holds land 'for the claimant only and not for another, for example using the land as his or her own backyard and not allowing others to so use the property.' Kitterman, 924 S.W.2d at 876. This element is satisfied by showing that others do not jointly possess or use the land. Martens, 195 S.W.3d at 556.
