The overpaid individual is at fault if they knowingly supplied information which they
knew or should have known was incorrect.
EXAMPLE: If an overpaid individual established their age as 65 based on recent proof but knowingly
withheld an earlier proof (e.g., a birth or baptismal certificate) which indicated
they were actually less than 65, they are at fault in causing the overpayment.
However, if there is valid reason to believe the incorrect information supplied was
given in good faith and that it was correct to the best of the individual’s knowledge,
you can find the individual is without fault.
