In the state of Kentucky, you must be at least 18 years old, and of sound mind to have a will prepared. You must sign the will yourself, and if it is not wholly written by you, then two witnesses must sign the will in your presence after you sign in their presence. Kentucky wills must be in writing, rather than videotaped. Your will can be handwritten or typewritten. You can change or revoke your will through a new will or a codicil to the current will.
