Martha Jansa executed a will naming her two sons as executors and leaving all her property to them. The will was properly signed and attested to by witnesses. Thereafter, Martha died. When Martha’s safe-deposit box at a bank was opened, the original of this will was discovered, along with two other instruments that were dated after the will. One was a handwritten document that left her home to her grandson, with the remainder of her estate to her two sons; this document was not signed. The second document was a typed version of the handwritten one; this document was signed by Martha but was not attested to by witnesses. Which of the three documents should be admitted to probate?
