In an effort to curb money laundering in residential real estate transactions, the Financial Crimes Enforcement Network (“FinCEN”) enacted the Anti-Money Laundering Regulations for Residential Real Estate Transfers rule (the “Rule”), which imposes extensive reporting requirements for certain non-financed residential real estate transactions. This post provides a high-level overview of the Rule and discusses a recent federal case that struck down the Rule as exceeding the authority granted to FinCEN by the Bank Secrecy Act (the “BSA”).
The Rule’s Enactment and History
FinCEN is a bureau of the U.S. Treasury tasked with enforcement of the BSA, which requires financial institutions to maintain records that are useful for the detection and prevention of money laundering. Stating that illicit use of residential real estate threatens economic and national security, FinCEN promulgated the Rule in 2024, imposing extensive reporting requirements for non-financed residential real estate transactions where ownership is transferred to an entity or trust (with limited exceptions).
Legal Challenge of the Rule in Flowers Title Companies v. Bessent
Flowers Title Companies (“Flowers”) filed suit challenging the Rule as unlawful under the Administrative Procedure Act. On March 19, 2026, the U.S. District Court for the Eastern District of Texas (the “Court”) ruled in Flowers Title Companies, LLC v. Bessent that the Rule exceeded FinCEN’s statutory authority under the BSA.
In response to Flowers’ challenge, FinCEN argued that two provisions of the BSA authorized its promulgation of the Rule: (1) 31 U.S.C. § 5319(g)(1), which authorizes FinCEN to require reporting of “any suspicious transaction”; and (2) 31 U.S.C. § 5319(g)(2), which permits FinCEN to require financial institutions to “maintain appropriate procedures, including the collection and reporting of certain information.” The Court rejected both of these arguments. First, it held that FinCEN is authorized to regulate “only those transactions that tend to arouse the belief that something is wrong” and FinCEN provided no persuasive explanation for its determination that the entire category of non-financed residential real estate transactions meets this definition. The Court agreed with Flowers that there are “myriad legitimate reasons” an individual would purchase property without financing and “there is nothing unusual about an investor creating [an incorporated entity] to acquire and hold real estate.”
Second, the Court held that 31 U.S.C. § 5319(g)(2) does not authorize FinCEN to impose substantive obligations on financial institutions to report information. Explaining that “reporting” is ordinarily not a “procedure” but rather “the substantive act of giving an account or making a record,” the Court ruled that this section of the BSA authorizes FinCEN to “require institutions to maintain procedures including maintaining collection and reporting procedures.” However, the Rule vastly expands this requirement, and FinCEN’s proposed interpretation of this statute “smuggles expansive reporting authority into a provision that is focused on procedures.” Therefore, the Court entered judgment in Flowers’ favor and issued an order that the Rule be vacated under 5 U.S.C. § 706(2).
Impact of the Order on Enforcement of the Rule FinCEN has announced that it will appeal the Flowers decision to the 5th Circuit Court of Appeals. Even though another federal court in Florida reached the opposite conclusion, the order vacating the rule applies throughout the country pending the appeal. FinCEN has issued an alert stating that reporting entities who do not file reports required under the Rule while the Court’s order remains in effect will not be subject to liability.
