if a notary was convicted of forgery fraud in 9/2013 but he commission was good for a signing on 4/20/2011 wouldnt it raise legal questions to if that

I don't think the fraud affects anything the Notary has attested to because the Notary attests to the fact that the person whose isgnature appears there is the person who actually signed it.  the notary does not attest to the validity of the documents.
