Yes, it is possible to get a handwritten document notarized. Notarization does not usually decide the legal status of a document. The validity of the document can only be verified by an appropriate authority including a court or an arbitration tribunal. The only purpose of getting a notary's seal on the document is to certify that a particular individual has signed it. However, a notarial certificate or form must be attached to the handwritten document for it to be notarized.
