Here's the fear almost every agent, conveyancer and jeweller has once they understand Tranche 2 properly. What if I report a client I still need to act for tomorrow? What if reporting a suspicion means I have to drop the deal, lose the commission, and explain to a furious client why the sale fell through? It's a reasonable worry. It's also based on a misunderstanding of how the system actually works, and Singapore's biggest money laundering case shows exactly why getting this wrong, in either direction, is what actually gets professionals in trouble.

As part of the fallout from Singapore's S$3 billion money laundering case, one law firm, Fortis Law Corporation, had already filed a suspicious transaction report on a client. That part it got right. The problem came after. The firm kept acting for the same client without properly documenting why it still considered that appropriate, and Singapore's Ministry of Law found this significant enough to penalise the firm as part of its broader enforcement action arising from the case.¹

Notice what the finding actually was. It wasn't that the firm reported a client and then kept working for them, that part is allowed, and we'll get to why below. The finding was that once the firm had a documented suspicion serious enough to report, it needed an equally documented reason for continuing to act, and it didn't have one. The paper trail stopped exactly where it mattered most.

This is the part that surprises most people. Under Australia's AML/CTF Act, lodging a Suspicious Matter Report does not require you to stop the transaction or end the relationship.² You can keep providing the service while AUSTRAC looks into it. The SMR is a notification to AUSTRAC, not a referral to end your business relationship, and not an accusation you're making to the client's face. In most cases, the deal proceeds exactly as it would have anyway.

What changes is what happens on your side of the desk. You now have a documented suspicion, a report lodged with AUSTRAC, and, from that point forward, an obligation to keep a proper record of your reasoning if you continue acting for that client. That's precisely the step the Fortis Law Corporation case shows going missing.

Under section 41 of the AML/CTF Act, the trigger is a suspicion formed on reasonable grounds, not proof, and not certainty.³ You don't need to know a crime has occurred. You need a genuine, reasonably grounded concern that a transaction might be connected to money laundering, terrorism financing, tax evasion, or another serious offence. Common triggers include a client's story not matching their financial profile, funds arriving from unexplained third parties, or a transaction structured in a way that only makes sense if someone is trying to avoid scrutiny, the same patterns covered in the second article in this series.

Once that suspicion forms, the clock starts immediately, not from when the transaction happens, but from the moment you actually form the suspicion.⁴ For most matters, you have three business days to lodge the report. If the suspicion involves terrorism financing, that shrinks to 24 hours.⁴ Waiting to "investigate a bit more" before reporting isn't how the obligation works. You report what you have, when you have it, and update AUSTRAC later if more information comes to light.⁵

Two details catch people out constantly. First, the obligation applies even if you decline to act for the client. Turning a suspicious customer away doesn't remove your reporting obligation, you still have to lodge the SMR.⁶ Second, you're required to keep records of the report and your reasoning for seven years, so a report filed once and never referenced again isn't compliant recordkeeping, it's exactly the gap that tripped up the Singapore firm.

Section 123 of the AML/CTF Act makes it a criminal offence to disclose to the client, or to anyone connected to them, that you have lodged, are lodging, or are considering lodging an SMR.⁷ This is called tipping off, and it carries penalties including imprisonment.⁸ It covers more than a direct statement. Hinting at it, changing your behaviour noticeably toward the client, or mentioning it to a colleague who has no need to know can all potentially breach the prohibition.⁹

This is precisely why the Fortis Law Corporation case matters so much for a small firm. You can't explain your suspicion to the client, and you generally shouldn't discuss it broadly with colleagues either. What you can do, and what the case shows you must do, is keep a clear, private, internal record of your reasoning for whatever you decide next, whether that's continuing the transaction, applying extra scrutiny, or declining to proceed. That written reasoning is the only thing that will protect you later if a regulator asks why you kept acting for a client you'd already reported.

You don't need a compliance department to get this right. You need a habit, applied consistently:

The professionals who get in trouble over Suspicious Matter Reports usually aren't the ones who never file one. They're the ones who file, then treat the box as ticked and stop thinking about the client, or the ones who never report at all because they're worried reporting means losing the deal. Neither fear is well-founded, and neither habit is safe. Reporting doesn't end the relationship. It just means everything you do afterward needs a reason you can show someone, if they ever ask.

The next article in this series looks at the single most common source of confusion once you start asking these questions properly: the difference between a client's source of wealth and their source of funds, and why mixing the two up is one of the easiest ways for an otherwise careful business to get fined.
