For most of a career in criminal defence, the generalist has been the default. You take the duty rota call, whatever it brings – a shoplifting matter on Monday, an ABH on Tuesday, a multi-handed conspiracy by Friday. That breadth has always been part of the job’s appeal, and for many practitioners it still is. But the economics and complexity of criminal practice have shifted enough that staying a generalist by default, rather than by choice, is starting to look like the riskier option rather than the safer one.
Volume crime work is precisely where legal aid funding pressure bites hardest. Fixed fees punish complexity, and the cases that pay reasonably are increasingly the ones requiring genuine specialist knowledge rather than general competence. That’s not a reason to panic – it’s a reason to think deliberately about where you sit on the spectrum between generalist and specialist, and whether building real depth in one or two areas might serve both your practice and your caseload better than spreading thin across all of them.
The ever-growing area of fraud
Fraud is the most obvious candidate, and the most lucrative. Financial crime caseloads have grown steadily, and a meaningful proportion of that work – particularly anything heading toward the Serious Fraud Office or a multi-handed conspiracy to defraud – involves privately paying or mixed-funded clients, expert forensic accounting evidence, and trials measured in months rather than days. It rewards comfort with financial documentation and a willingness to sit with experts rather than against them. It’s also one of the few corners of criminal defence where complexity-based funding still reflects the actual work involved, rather than fighting against it.
Serious sexual offences
RASSO work – rape and serious sexual offences – sits at the opposite end in terms of funding model but is arguably the area with the clearest supply gap right now. These cases demand specific accreditation, fluency with vulnerable witness measures and intermediaries, and a particular kind of resilience given the length and sensitivity of the trials involved. Caseloads in this category have been rising nationally for years, while the number of practitioners willing and accredited to take them on has not kept pace. For anyone prepared to invest in the training and the emotional labour the work demands, that gap is a genuine opening rather than a saturated market.
A bridge between corporate and criminal law
Regulatory crime – health and safety, environmental, financial services and trading standards prosecutions – is the quietest of the four, and probably the most underexplored by criminal defence firms specifically. It sits in the gap between criminal and corporate practice: clients are typically companies or directors rather than individuals facing volume crime, instructions are often privately funded, and the work rewards solicitors who can speak comfortably to compliance teams and boards as well as to a bench. It’s a natural bridge for anyone with an interest in corporate work who doesn’t want to leave criminal practice behind entirely.
Terrorism work is the narrowest of the four by a wide margin – a small pool of practitioners, security clearance requirements, and a heavy weighting toward SIAC and special advocate appointments rather than conventional trial work. It’s not a niche many will build a whole practice around, but for those already working adjacent to national security or extradition matters, it’s worth recognising as a distinct specialism with its own funding arrangements and its own route in, rather than something that simply falls out of general crime experience.
Building a specialism
None of this means abandoning a general caseload overnight, and few firms would want a solicitor to. The more realistic path is incremental: take the cases adjacent to the area you want to build, even when they’re harder or less immediately profitable than the volume work you could take instead. Build relationships with the junior counsel and chambers who specialise in that area – referrals in a niche tend to flow through reputation within a fairly small circle, and that circle takes years to enter, not months. Pursue the accreditation routes that exist (RASSO training is the clearest example, but equivalent CPD pathways exist for fraud and regulatory work too), and look for opportunities to write or speak on the subject, which does as much for a directory submission as case volume alone ever will.
Arguably, the firms and practitioners best placed over the next decade are unlikely to be the ones who stayed broadest. They’re more likely to be the ones who used the current pressure on volume crime as the reason to specialise and started early enough that the depth was already there by the time everyone else noticed the gap.
