In most states they can accept a draft will. AFAIK of only one state (Michigan) allowed an unsigned will to take precedent over a signed will (on appeal) but it required clear and convincing evidence of the deceased intent. Which I doubt was just a “he told me.”
Accepting a draft will is not the same thing as honoring an unsigned will when a legal will has been signed and witnessed.
How dare you inject actual knowledge into a thread on the internet!
