The quality or state of being fraudulent; the practice of deception or dishonest schemes.
From 'fraudulent' (Latin 'fraudulentus', deceitful) + '-ence' (state or quality). The noun form converts the adjective into an abstract concept.
Both 'fraudulence' and 'fraudulency' exist, but 'fraudulence' dominates—it's a battle between '-ence' and '-ency' suffixes that English largely resolved in favor of '-ence'.
