Most types of property may be seized and
forfeited administratively. The most important
exceptions are real property and personal property
(other than cash or monetary instruments) having
a value in excess of $500,000. Such property must
always be forfeited judicially. See 19 U.S.C.
§ 1607 (setting maximum dollar value on
administrative forfeiture of personal property); 18
U.S.C. § 985(a) (real property may never be
forfeited administratively).
