In this paragraph, "justifiable reliance" means that the person to whom the notice is sent has made reasonably diligent efforts to verify the representation, regardless of whether the representation is made pursuant to statutory or other legal authority.2. At the time the notice is sent the person to whom it is sent is suffering from insanity or legal incompetence or incapacity, including minority.3. The person to whom the notice is sent shows by clear and convincing evidence that the notice was not received.C. The late filing shall not be excused under subsection B of this section if the person to whom the notice is sent or the person's legal counsel knew or, with the exercise of reasonable care and diligence, should have known of the fact of the notice at any time during the filing period.
