Yes, a Notary Public can notarize a minor as long as all the requirements for the notarization are met.
Here’s the problem: A Minor cannot enter into a contract. They cannot sign a Grant Deed, Deed of Trust or any other contractual agreements; therefore they can not execute loan or real estate documents.
What do you do? Always check the birth date on the parties identification to first verify that the age description matched the party appearing before you. If they are under the age of 18, immediately adjourn the signing and contact the appropriate parties.
