Motion to Suppress in CAFRA Forfeiture Cases
When your money or property is seized without a warrant, one of the most important defenses in the case requires filing a motion to suppress illegally obtain evidence after an unlawful stop, a prolonged detention, a warrantless search, or the seizure of evidence.
The Fourth Amendment of the United States protects the “right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” U.S. CONST. amend. IV.
These Fourth Amendment protections are codified in Rule G(8)(a), which provides that “a party with standing to contest the lawfulness of the [property’s] seizure may move to suppress use of the property as evidence.”
For this reason, the Fourth Amendment applies to the seizure and subsequent civil forfeiture of property following a warrantless stop and search. For example, in One 1958 Plymouth Sedan v. Commonwealth of Penn., 380 U.S. 693, 85 S. Ct. 1246, 14 L. Ed. 2d 170 (1965), the court held that the Fourth Amendment’s exclusionary rule applies to civil forfeiture proceedings.
Additionally, the Fourth Amendment’s requirements appear in the statutory framework of CAFRA. In fact, CAFRA specifically requires that seizures be made pursuant to a warrant or be based upon probable cause and made pursuant to a lawful search or arrest. See 18 U.S.C. § 981(b)(2)(B).
The forfeiture action may also be based on property seized by a state or local law enforcement agency and transferred to a federal agency, although those searches and seizures must also be lawfully conducted in compliance with the Fourth Amendment. See 18 U.S.C. § 981 (b)(2)(C).

Filing a Motion to Suppress in a Civil Asset Forfeiture Action
When the Claimant files a motion to suppress, it can also send the government civil discovery requests relating to the stop, detention, search and seizure. The government should not be allowed to evade judicial inquiry into whether the stop, detention, search and seizure complied with the Fourth Amendment.
The Fourth Amendment applies in civil forfeiture cases and provides important guardrails in deterring government abuses and suppressing unlawfully obtained evidence. United States v. $186,416.00 in U.S. Currency, 590 F.3d 942, 949-950 (9th Cir. 2010)(citing One 1958 Plymouth Sedan v. Pennsylvania, 380 U.S. 693, 696 (1965)); see United States v. $493,850.00 in U.S. Currency, 518 F.3d 1159, 1164 (9th Cir. 2008).
Supplemental Rule G(8)(a) provides that “[i]f the defendant property was seized, a party with standing to contest the lawfulness of the seizure may move to suppress use of the property as evidence.”
The claimant can move to suppress evidence gathered in a civil asset forfeiture case “much like a defendant in a criminal case who brings a motion to suppress.” See United States v. $200,255.00 in U.S. Currency, 2006 U.S. Dist. LEXIS 40049, 2006 WL 1687774, *6 (M.D. Ga. June 16, 2006), the Court recognized the importance of filing a motion to suppress by citing the following cases:
- United States v. $99,990.00 in United States Currency, 69 Fed. Appx. 757, 2003 WL 21698849 (2003) (unpublished) (addressing a civil forfeiture claimant’s motion to suppress currency seized during search of hotel room and car;
- United States v. 4,432 Mastercases of Cigarettes, 448 F.3d 1168, 2006 WL 1511773 (2006) – addressing a civil forfeiture claimant’s motion to suppress cigarettes seized during a warrantless search of a storage area; and
- United States v. One Piece of Real Prop. Located at 5800 SW 74th Ave., 363 F.3d 1099 (11th Cir. 2004) – addressing a civil forfeiture claimant’s motion to suppress evidence obtained during the search of a house.
As with any challenge pursuant to the Fourth Amendment, the Court requires inquiry into whether the individual initiating such challenge has standing to do so. For example, in Rakas v. Illinois, 439 U.S. 128, 143, 99 S. Ct. 421, 58 L. Ed. 2d 387 (1978), the United Supreme Court stating that a defendant must have a “reasonable expectation of privacy” in the place being searched to bring a Fourth Amendment challenge.
One common scenario involves the warrantless seizure of property that begins with a traffic stop of a suspect’s vehicle. In those cases, the court might evaluate the validity of the initial traffic stop, whether the driver granted valid consent to search the vehicle, and whether the officers exceeded the scope of the consent granted in conducting any subsequent search.
Another common scenario involves a law enforcement officer stopping a traveler to search their luggage at an airport or train station. In those cases, the court might consider the legality of the initial detention from the inception, whether the detention was unreasonably prolonged, whether the traveler really granted free and voluntary consent for the search, and the validity of any subsequent search of the traveler or their luggage.
The exclusionary rule carries particular weight, because if the government loses the motion to suppress and has no independent evidence connecting the subject property to the underlying crime such as drug trafficking, then the government is unlikely to carry its burden of establishing forfeitability. A successful motion to suppress may well determine the outcome of a civil forfeiture action. In the interest of due process and the protections enshrined in the Fourth Amendment, that motion should be heard.
How the Fourth Amendment Exclusionary Rule Might Apply in Civil Asset Forfeiture
As epxlained in United States v. $277,000.00 U.S. Currency, 941 F.2d 898, 902 (9th Cir. 1991) (“[A]ny evidence which is the product of an illegal search or seizure must be excluded in the forfeiture hearing.” Likewise, in United States v. One (1) 1971 Harley-Davidson Motorcycle, 508 F.2d 351, 351-52 (9th Cir. 1974), the court found that “evidence derived from a search in violation of the Fourth Amendment must be excluded at a forfeiture proceeding,” but “so long as the requirements for forfeiture were proven by evidence not tainted by the seizure, the contraband could properly be forfeited.”
Other Fourth Amendment protections apply in civil forfeiture cases. For example, the court may not consider the amount of money in dispute in the forfeiture action when that money is the fruit of an unlawful search. United States v. $191,910.00 in U.S. Currency, 16 F.3d 1051, 1063, 1065 (9th Cir. 1994), superseded by statute on another ground as stated in United States v. $80,180.00 in U.S. Currency, 303 F.3d 1182, 1184 (9th Cir. 2002).
In United States v. $493,850.00 in U.S. Currency, 518 F.3d 1159, 1165 (9th Cir. 2008), the court recognized it “cannot consider the amount of currency that the government illegally seized.”
Even when the court may recognize that illegally seized property consists of currency, if the currency was illegally seized, the money itself must not be introduced as evidence in a forfeiture proceeding.
The reason the .exclusionary rule applies in civil forfeiture cases is because civil forfeiture “enable[s] the government to seize . . . property without any predeprivation judicial process and to obtain forfeiture of the property even when the owner is personally innocent.” Leonard, 580 U.S. at 1179.
Modern civil forfeiture statutes are “designed, at least in part, to punish the owner of property.” Id. But through a civil asset forfeiture proceeding, the government avoids many of the “procedural protections that accompany criminal proceedings.” Id. Since civil forfeiture is ripe for abuse and that abuse is disproportionately likely to affect the “groups least able to defend their interests in forfeiture proceedings.” Id. at 1180.
The “quasi-criminal” proceeding brings significant constitutional and due process concerns noted by the courts. See $191,910.00, 16 F.3d at 1068 (quoting United States v. Riverbend Farms, Inc., 847 F.2d 553, 558 (9th Cir. 1988)); Culley v. Marshall, 601 U.S. 377, 401 (2024) (Gorsuch, J., joined by Thomas, J., concurring); id. at 414-15 (Sotomayor, J., joined by Kagan and Jackson, JJ., dissenting); United States v. $1,106,775.00 in United States Currency, 131 F.4th 710, 727 (9th Cir. 2025) (Bress, J., dissenting), reh’g en banc granted, opinion vacated, 157 F.4th 1102 (9th Cir. 2025).
For these reasons, the exclusionary rule allows for a distinctive and essential safeguard against government abuse unique to the civil forfeiture scheme. The government maintains a “strong financial incentive to prevail in civil forfeiture actions,” the possibility of exclusionary sanctions can be “especially effective in deterring law enforcement agents from engaging in illegal [search and seizure].” $186,416.00, 590 F.3d at 950.
For this reason, the failure to apply the exclusionary rule when necessary directly “reward[s] the government” for its Fourth Amendment violation. $493,850.00, 518 F.3d at 1165. Application of the exclusionary rule in civil forfeiture cases “protects judicial integrity by ensuring that the courts do not serve as a conduit through which the government fills its coffers at the expense of those whose constitutional rights its agents violated.” $186,416.00, 590 F.3d at 950.
The Extent of the Required Suppression in a CAFRA Forfeiture Action
Another issue relates to what remedy the Court should apply when deciding whether to suppress evidence, what evidence to suppress, and the impact of evidence being suppressed on the underlying forfeiture action.
However, “the mere fact that property was illegally seized does not immunize that property from forfeiture.” United States v. One 1977 Mercedes Benz, 708 F.2d 444, 450 (9th Cir. 1983). Rule G(8)(a) of the Supplemental Rules for Admiralty or Maritime and Asset Forfeiture Claims provides that: “[s]uppression does not affect forfeiture of the property based on independently derived evidence.”
However, “the mere fact that property was illegally seized does not immunize that property from forfeiture.” United States v. One 1977 Mercedes Benz, 708 F.2d 444, 450 (9th Cir. 1983). See also Rule G(8)(a) of the Supplemental Rules for Admiralty or Maritime and Asset Forfeiture Claims (“Suppression does not affect forfeiture of the property based on independently derived evidence”).
For example, in United States v. 482,627.00 in U.S. Currency, 2005 U.S. Dist. LEXIS 9169, 2005 WL 1140603, *3 (2005) (unpublished), the court found that “an illegal search and seizure does not immunize goods from forfeiture so long as the Government satisfies its burden of proof by untainted evidence.”
In United States v. One 1974 Learjet 24D, 191 F.3d 668 (6th Cir. 1999), the court dated that seizure and forfeiture each implicate different evaluations of probable cause and noting that a lack of probable cause to seize the plane “would not, by itself, have ended the forfeiture proceedings.”
In United States v. 30,000.00 in United States Currency, 30 Fed.Appx. 473, 480 (6th Cir. 2002) (unpublished), the court found that “the absence of probable cause for a seizure may simply result in suppression of the evidence in a forfeiture proceeding. However, the failure to establish requisite probable cause for forfeiture precludes forfeiture.”
Warrantless Seizures in CAFRA Forfeitures under Section 981(b)
Section 981(b) specifically provides that:
“Seizures pursuant to this section shall be made pursuant to a warrant obtained in the same manner as provided for a search warrant under the Federal Rules of Criminal Procedure, except that a seizure may be made without a warrant if–
(A) a complaint for forfeiture in rem has been filed in the United States district court and the court issued an arrest warrant in rem pursuant to the Supplemental Rules for Certain Admiralty and Maritime Claims;
(B) there is probable cause to believe that the property is subject to forfeiture and —
(i) the seizure is made pursuant to a lawful arrest or search; or
(ii) another exception to the Fourth Amendment warrant requirement would apply; or
(C) the property was lawfully seized by a State or local law enforcement agency and transferred to a federal agency.
18 U.S.C. § 981(b)(2).
Independently Derived Evidence in a Civil Asset Forfeiture Case
If a Claimant prevails on their motion to suppress, the government might still aim to prove that the currency is subject to forfeiture, but it must do so using “independently derived evidence.” Supp. R. G(8)(a). See also $277,000.00, 941 F.2d at 902 (holding that “the mere fact that property was illegally seized does not immunize that property from forfeiture”); $493,850.00, 518 F.3d at 1170 (“[R]egardless of the amount of currency at issue . . . the evidence connecting [claimants] with cocaine trafficking is overwhelming.”).
