View a sample handwritten will at OKlaw.org. A valid "holographic" will must be written entirely in the cursive writing or hand printing of the testator. A will with even one typewritten word is not a valid holographic will, says Legal Aid Services of Oklahoma.
A handwritten will must include the full legal name, city, state and country of the testator. If any wills were made prior to the handwritten will, the testator must state that the new will revokes and renders invalid any previous will, according to HG Legal Resources.
In 2015, 26 states allow handwritten, uncontested wills. In some cases, sailors at sea and soldiers at war may write a valid last will and testament by hand, according to Nolo.com.
