Net Equity Values
Whether a property should be seized must be documented during the pre-seizure process. The following guidelines set minimum net equity levels that generally must be met before federal forfeiture actions are instituted. The net equity values are intended to decrease the number of federal seizures, thereby enhancing efforts to improve case quality and to expedite processing of the cases we do initiate. The thresholds are also intended to encourage state and local law enforcement agencies to use state forfeiture laws. These thresholds are to be applied in direct and adoptive cases. In general, the minimum net equity requirements are:
Residential Property and vacant land —minimum net equity must be at least 20 percent of the appraised value, or $20,000, whichever is greater. As a general rule, the Department of Justice does not seize or adopt contaminated real properties. See Contaminated Real Property Policy, at USAM 9-111.400.
Vehicles—minimum net equity must be at least $5,000. The value of multiple vehicles seized at the same time may be aggregated for purposes of meeting the minimum net equity. If the person from whom the vehicle was taken was or is being criminally prosecuted by state or federal authorities for criminal activities related to the property and there is justification for a low value seizure (such as the vehicle being used to facilitate criminal activities), the minimum net equity is $2,000. The arrest of the person from whom the property is taken, for an offense related to the illegal use or acquisition of the property for which a forfeiture action may be brought, satisfies the condition of criminal prosecution. This restriction does not apply in the case of seizures by the United States Immigration and Customs Enforcement of vehicles used in the smuggling of aliens or in the case of vehicles modified or customized to facilitate illegal activity.
Cash - minimum amount must be at least $5,000, unless the person from whom the cash was taken was criminally prosecuted or is being prosecuted by state or federal authorities for criminal activities related to the property, in which case, the amount must be at least $1,000.
Aircraft—minimum net equity must be at least $10,000. Note that failure to obtain the log books for the aircraft will reduce the aircraft's value significantly.
Vessels—minimum net equity must be at least $10,000.
All Other Personal Property—minimum net equity must be at least $1,000 in the aggregate. Exceptions from the minimum net equity requirement should not be made for any individual item if it has a value of less than $1,000. Such exceptions can be made if practical considerations support the seizure (e.g., 20 items of jewelry, each valued at $500, might be seized, as the total value of the items is $10,000 and the cost of storing 20 small items of jewelry is not excessive).
Heads of investigative agencies may continue to establish higher thresholds for seizures made by their agencies. If an investigative agency head establishes higher monetary thresholds than those set out in the directive, the Asset Forfeiture and Money Laundering Section must be advised in writing of the change.
I like how they'll take 5 grand if you're not charged with a crime... but will go as low as 1k if you are.
