Cho Wang handwrote a three-page will in pencil. At the end of the business day, he took the will to an attorney and asked that it be typed. Since Cho mentioned that he was leaving on a vacation and would be out of state for one week, the paralegal for the firm asked if he would like to sign the handwritten (holographic) will. Cho did sign the will, but he also stated that he would return after his trip to sign "his will," i.e., the typed will. While on vacation, Cho suddenly became ill and died. Answer the following:

1. Is a signed holographic will a valid will in your state?
2. Are witnesses required for a holographic will?
3. Should the executed holographic will operate as Cho's will pending the execution of the typewritten will? Explain.
