The only thing a notary should do regarding a will are these steps --> - immediately after the will is executed by the testator, and the correct number of witnesses sign as witnesses, the notary administers an oath to the witnesses to establish their residence; - the notary determines the witnesses lack of interest in the will; - the notary then evaluates that the testator appeared to be in possession of all of his/her good senses and was of sound mind at the ceremony; - the notary determines that the testator signed in the presence of the correct number of witnesses and that they signed in the presence of each other and the testator.

That is all the notary can do and those steps make the will self-proving. This is a critical ceremony. And these steps are one of the reasons why people hire attorneys to get their wills done, because this self-proving ceremony is the province of attorneys. If you try to have the notary do anything else, the veracity of the will is in question.
