Two contiguous lots, 1 and 2, are owned by X and Y respectively. (X and Y are not in possession.) The lots are conveyed by an invalid deed from Z to A, who enters lot 1 and occupies it in the usual manner for the period required by the statute of limitations. Subsequently, A sues X and Y to quiet title to lots 1 and 2. What result? Would it matter if X had executed the deed? If X had executed the deed and A had entered lot 2? See Wheatley v. San Pedro, Los Angeles & Salt Lake Railroad, 147 P. 135 (Cal. 1915); Brock v. Howard, 200 S.W.2d 734 (Ky. 1947).
