Except as otherwise provided in subsection (b), section four of this article, the failure of a notarial officer to perform a duty or meet a requirement specified in this article does not invalidate a notarial act performed by the notarial officer. The validity of a notarial act under this article does not prevent an aggrieved person from seeking to invalidate the record or transaction that is the subject of the notarial act or from seeking other remedies based on law of this state other than this article or law of the United States. This section does not validate a purported notarial act performed by an individual who does not have the authority to perform notarial acts.
