William Joseph Harris qualified as a solicitor in April 1980. For most of his career, he was exactly the kind of professional this newsletter is written for: a sole practitioner, running his own small firm, William Harris Solicitors, out of Lancaster in the UK. His work was mostly residential conveyancing and probate, the bread and butter of a small legal practice. He wasn't a criminal. He wasn't accused of laundering a single pound himself. And in August 2025, at 71 years old, he was struck off the Roll of Solicitors and ordered to pay costs of £29,775.84.1
If you run a small conveyancing, legal or property business, his case is worth sitting with, because almost nothing about it involves dramatic criminality. It's a story about paperwork, and about what happens when a small firm treats compliance as something to get around rather than something to actually do.
What actually happened
Between January 2022 and September 2023, Harris handled 63 conveyancing transactions worth a combined £8.8 million.2 Under UK law, specifically the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017, he was required to properly check where his clients' money was coming from and to have adequate systems in place to do that checking. He didn't.
The Solicitors Disciplinary Tribunal found "widespread and fundamental non-compliance with critical regulations" representing "systemic failures throughout the six years of his sole practice."3 That's not a tribunal describing one bad transaction. That's a tribunal describing an entire small business run for years without the basic machinery Tranche 2 style regulation exists to require.
It gets worse. Under UK rules, firms are required to have a Firm Wide Risk Assessment, essentially a written document setting out how the business identifies and manages money laundering risk. In December 2019, Harris told the SRA in writing that his firm had one. It didn't. When the SRA finally interviewed him in 2023, he admitted he didn't actually know what a Firm Wide Risk Assessment was. The document he'd previously handed to a forensic investigator as "his" risk assessment turned out to have been downloaded from the HMRC website.4
The Tribunal treated this not as an innocent misunderstanding but as dishonesty, "a very serious example," given that Harris was simultaneously his firm's solicitor, Compliance Officer for Legal Practice, Compliance Officer for Finance and Administration, and Money Laundering Reporting Officer, all at once.5 In a small firm, one person often really does wear every one of those hats. The Tribunal's point wasn't that this is unusual. It's that wearing all those hats makes it more important to actually do the job behind each title, not less.
On top of the AML failures, Harris had also failed to return more than £100,000 in residual client balances across 54 accounts, some of it, the Tribunal found, held back "for years."6 He'd repeatedly missed deadlines for submitting the accountant's reports his firm was legally required to file, in one instance producing an overdue report and then sitting on it for another eight months before sending it to the regulator.7
Basis for the Tribunal's Decision
The SDT's own words are worth reading directly, because they explain the reasoning in a way that's easy to translate into an Australian context. The Tribunal found that the firm's "vulnerability to money laundering and terrorist financing, underscored by £8.8 million in unverified funds, posed a direct threat to the integrity of the legal profession and public safety."8
Read that carefully. Nobody proved Harris's clients were criminals. Nobody proved the £8.8 million was dirty money. The finding was that a solicitor's job includes making sure it isn't, and that not checking is itself the offence. That's precisely the shift Tranche 2 brings to Australia from 1 July 2026. The obligation isn't "don't help criminals." It's "have a system that would catch it if you were about to."
Relevance for Small Practices
The other cases in this series, Singapore's S$3 billion laundering scandal, the Luanda Leaks investigation, the Zamira Hajiyeva Unexplained Wealth Order in London, all involve enormous sums and, frankly, a certain distance from what a small Australian agency or conveyancing practice actually looks like. Harris's case doesn't have that distance. He ran a business that looked a great deal like the businesses reading this newsletter: one person, a modest regional practice, conveyancing and probate as the bread and butter, and every compliance title stacked onto a single person's plate.
He wasn't struck off because a criminal used his firm. He was struck off because when the regulator asked whether he had the basic paperwork every firm his size is required to have, he said yes when the true answer was no, and because for six years, nobody at his firm was actually checking where client money was coming from.
What a small firm should take from this
A few things stand out as directly transferable to what AUSTRAC will expect from Australian Tranche 2 entities from 1 July 2026:
A written risk assessment isn't optional paperwork, it's the thing that gets checked first. If a regulator ever asks whether you have one, you need an honest yes, backed by an actual document you can produce, not a downloaded template you've never adapted to your own business.
Wearing multiple compliance hats as a sole trader doesn't reduce your obligations, it just means there's nobody else to catch it if you don't meet them.
Source of funds checks apply to ordinary-looking transactions too. None of Harris's 63 clients were flagged as obviously suspicious. The failure was that nobody was systematically checking any of them, which is exactly the gap Tranche 2 closes.
Delay and inaccurate answers to a regulator make everything worse. Much of what turned this into a strike-off, rather than a warning or a fine, was the dishonesty about the risk assessment and the slow, incomplete responses to the SRA once concerns were raised.
Summary
Harris isn't a cautionary tale about criminals slipping money past a solicitor. He's a cautionary tale about a small, otherwise unremarkable legal practice that treated AML compliance as a box to tick rather than a system to run. That's a far more common failure mode than deliberate complicity in laundering, and it's the one most small Australian real estate, legal, conveyancing and accounting businesses are actually at risk of falling into once Tranche 2 obligations begin.
Harris's failure wasn't a single dramatic mistake. It was the accumulation of a business that never nailed down the difference between checking a client's paperwork and actually understanding where their money came from. The next article in this series looks at exactly that distinction: source of wealth versus source of funds, the single area of confusion that trips up more small firms than any other requirement in the AML/CTF regime.
