Law Enforcement and FIU Requests

The Two-Way Street With Law Enforcement

Investigations rarely sit inside one institution. Money moves across banks and borders, so the USA PATRIOT Act created formal channels for information flow between institutions, Financial Intelligence Units (FIUs), and law enforcement. The Financial Crimes Enforcement Network (FinCEN) is the U.S. FIU. The CAMS exam tests the Section 314(a) and Section 314(b) programs precisely, along with how to handle subpoenas and court orders.

Section 314(a): Law-Enforcement Requests

Section 314(a) is a mandatory program. Law enforcement, via FinCEN, sends institutions a list of named subjects suspected of money laundering or terrorist financing. The institution searches its records for matches and reports positive hits back to FinCEN within the stated timeframe.

Key exam points: a 314(a) match means the institution must report the match to FinCEN, but it does not by itself require filing a SAR, freezing the account, or closing the relationship. The institution may not tell the customer it appeared on a 314(a) list, and it may not use the list for general due diligence — only to respond to the request.

Section 314(b): Voluntary Information Sharing

Section 314(b) is voluntary. Registered financial institutions may share information with each other to identify and report possible money laundering or terrorist financing. Participation requires registering with FinCEN and provides a safe harbor from liability for sharing in good faith within the program's scope. It cannot be used to circumvent SAR confidentiality or for unrelated purposes.

Subpoenas, Court Orders, and FIU Requests

Institutions also receive grand-jury subpoenas, administrative subpoenas, court orders, and direct FIU requests. The correct handling is procedural and the exam expects it:

1. Validate the request — confirm it is authentic, properly issued, and from an authorized authority.
2. Route it through legal and compliance; front-line staff should never respond directly.
3. Scope the production to exactly what is requested — over-production can breach privacy law; under-production can be obstruction.
4. Document the search and what was produced.
5. Preserve confidentiality — do not tip off the customer that a request was received.

A Worked Example

A bank receives a 314(a) request naming "John A. Doe." It searches and finds an account for that exact identity. It reports the positive match to FinCEN within the deadline, logs the search, and continues normal operations — it does not freeze the account, file a SAR solely because of the match, or notify Mr. Doe. Separately, if a valid grand-jury subpoena later demands account records, legal reviews the subpoena's scope and produces only the records specified.

Keep Seizure and Forfeiture Tools Straight

The exam distinguishes information requests from asset actions. A 314(a) match or a subpoena does not itself freeze funds. Freezing or seizing assets requires separate legal process — a seizure warrant, a court order, or, for sanctioned parties, the blocking obligation under Office of Foreign Assets Control (OFAC) rules. Confusing "report the match" with "freeze the account" is a frequent trap.

Cross-Border Cooperation

Money crosses borders, so investigations often need foreign records. Two channels matter for the exam:

• Mutual Legal Assistance Treaties (MLATs) — formal government-to-government agreements that let authorities request evidence and records from another country. They are reliable but slow.
• Egmont Group — the global network of more than 170 FIUs that share financial intelligence FIU-to-FIU, faster than MLATs but for intelligence rather than court-admissible evidence.

An institution does not invoke these itself; it responds to lawful requests routed through its FIU or law enforcement. Understanding the channels helps you recognize why a foreign request arrives and how to validate it.

Building the Right Internal Process

A controlled program centralizes incoming legal requests with a single team that logs each request, tracks deadlines, confirms authenticity with the issuing authority, coordinates legal review, and records exactly what was produced. Front-line staff are trained to forward — never answer — a subpoena or agent inquiry, and to never reveal the request to the customer. This protects the institution from both obstruction (under-producing or tipping off) and privacy breaches (over-producing beyond scope), the two failure modes the exam pairs together.

Common Traps

• Assuming 314(a) requires a freeze or SAR. It requires reporting the match; further action depends on independent suspicion.
• Using 314(a) lists for marketing or general screening. Prohibited.
• Responding to a subpoena without legal review or producing beyond its scope.
• Telling the customer about a request — a tipping-off violation.
