I saw someone mention a handwritten will. It reminded me that my hoarder mother is nearly finished writing hers. It’s covered in koolaid and cigarette ashes. Still readable. In probating my dad's will, I was told several times how important the original will is in the process.
It will certainly be awkward for me to present this will to a lawyer. Ugh.
If you really want to be safe, once this is finished, go with the elder to an attorney and do this legitimately for safety with the attorney keeping of the two originals as always they do.
Remember also that an unsigned and undated will is worthless. Get two disinterested witnesses if you are able.
What is the reason you are going to present the Will to a lawyer? Are you going to have the lawyer get her Will typed from her handwritten draft and then witnessed and notarized for her?
Wills are extremely important documents, and it's imperative that they are done the right way. What she's doing is already a disaster!
