How to choose & be a Health Care Proxy: https://theconversationproject.org/wp-content/uploads/2017/03/ConversationProject-ProxyKit-English.pdf
As a Notary Public, it is our job to make sure the signer is aware of the document they are signing. One of the problems with signing Wills, that we have encountered, is that many of the clients order the forms from the internet. We do not recommend this as we have later found that most of these packages are incomplete and can be challenged in a court of law.
Hospitals do provide Advanced Directive forms. They include a Living Will, a Durable Power of Attorney for Medical Affairs (this one includes the advanced directives), and a Durable Power of Attorney for Financial Affairs. You may even see a Last Will & Testament in this package as well.
The signer must demonstrate a full understanding of the document to be notarized.
Make sure that the nurses know not to administer medication to the signer that will make them incoherent, within eight hours of the signing.
Wake them up at least an hour before the appointment.
Can the signer sign their name? Have a family member test them out before the appointment.
If not - to sign by Mark — have 2 “disinterested” witnesses available.
Have a valid ID on hand
Please confirm you have the document(s) and they are filled out completely.
