An attested witness is one who is present when the document is signed and who can verify that the signature is genuine. An affirming witness is one who has seen the signature of the document's signatory on a prior occasion and can confirm that it is the same signature on the document being attested. A solemnizing witness is one who witnesses the signing of the document and can verify that the signatory appeared to understand the document's contents.
