I am unsure what an "unlicensed" notary is. If a notary's commission has expired, that person is no longer a notary and cannot legally notarize documents. If a notary with an expired-commission notarizes a document, the expired-commission notary can face fines or jail-time. The legal status of the improperly notarized document varies from state to state. Asking an expired notary to work, via email or otherwise, is not a crime and does not necessarily constitute an attempt at fraud. If an uncommissioned notary is soliciting work, that person is committing fraud.
Nope.
No. Absolutely not. It is a requirement to have a VALID NOTARY SEAL to legitimize the document.
Having a passport trumps any other type of identification, so if they have that, and the signature matches, all is good. An expired license is worthless as ID. Notary laws differ from state to state. Some states allow the usage of expired state-issued identification (such as a drivers license) as proof of identity for having a document notarized, others do not. The notary should be familiar with the laws of the state that he or she is licensed to operate in, so if the notary refuses to accept an expired driver's license as proof of identity, you might ask if that's a personal rule (in which case the notary may be able to recommend a more lenient notary) or a state law (in which case it won't do any good to go to a different notary).
It should be prominently displayed on your Commission paper or certificate.
Oh, isn't that a happy little question! Unfortunately, once a notary's commission expires, they can no longer notarize any documents. But don't worry, they can simply renew their commission and get back to notarizing beautiful documents in no time. Just a little bump in the road, nothing we can't handle with a little positivity and a fresh canvas.
Bonding is not required to be a notary.
If the notary's license was current at the time he notarized your document, your document is perfectly legal. If there is a question of legality, have the dates of the POA amended and resign and notarize.
To become a notary, you will need to receive training from the National Notary Association. This generally costs about $500.
No because to be a notary you need to be a resident of that particular state.
nothing
You do not need a notary public to buy or sell a car, but make sure you have a clear, signed receipt for the sale.
