"In a civil forfeiture action, the government need only prove by a preponderance of evidence that the property is subject to forfeiture. Criminal forfeiture, which is apparently much less common than civil forfeiture (Hyde, 1995), usually accompanies criminal charges and is more difficult because of the proof-beyond-a-reasonable-doubt standard (Warchol, Payne, and Johnson, 1996:53-54). Civil forfeiture may thus be pursued more frequently because of the lower standard of proof. In fairness, however, criminal forfeiture may be preferred sometimes because restrictions exist on divulging the amount of assets forfeited (Clingermayer, Hecker, and Madsen, 2005)."
