Criminal Law Careers
Criminal law covers the prosecution and defence of offences, from investigation and charge through trial, sentencing and appeal.
Criminal law is the prosecution and defence of conduct the state treats as an offence. It runs from police investigation and charge through bail, plea, trial, sentencing and appeal, and spans everything from everyday crime to complex white-collar and financial-crime cases. It is advocacy-heavy, procedure-driven, and among the most public-facing areas of legal practice.
Practitioners work on one or both sides - prosecution (for the state) and defence (privately, through legal aid, or as a public defender) - and the work carries real human stakes. It is a strong route for lawyers drawn to courtroom advocacy and to the justice system. This guide covers the work, the roles, who hires, what it pays, qualifications and how to break in.
What criminal lawyers actually do
Defence work covers advising suspects, bail applications, case preparation and disclosure review, plea advice, trial advocacy, sentencing mitigation and appeals. Prosecution work covers reviewing evidence and charging decisions, building and presenting the case, and conducting trials on behalf of the state. White-collar and financial-crime practice handles investigations, regulatory enforcement and complex fraud, often overlapping with compliance and corporate work.

What it pays
Pay varies more widely than most specialisms: high-volume legal-aid and junior prosecution work sits at the lower end, while white-collar and financial-crime defence at major firms is among the better-paid contentious work. Market and sector (public vs private) drive the bands. The live roles below show disclosed pay where the employer provides it.
Qualifications & certifications
A recognised law degree and qualification to practise is the base, and advocacy in serious matters often requires a specific route (bar admission or its local equivalent). The skills that matter most are persuasive advocacy, mastery of criminal procedure and evidence, sound judgment, and resilience under pressure and public scrutiny.
How to break in
Common entry routes are a criminal seat or pupillage at a defence firm or chambers, a position in the prosecution service, or a legal-aid or public-defender role. Build courtroom experience early, learn criminal procedure thoroughly, and consider specialising in a growth area such as white-collar and financial-crime defence, which overlaps with compliance and corporate work.

Frequently asked questions
Can you do both prosecution and defence?
Many criminal lawyers work primarily on one side, but the underlying skills - procedure, evidence and advocacy - transfer, and some practitioners move between prosecution and defence over a career. The day-to-day perspective differs, but the craft is shared.
Is criminal law well paid?
It varies more than most areas. High-volume legal-aid and junior prosecution roles sit at the lower end, while white-collar and financial-crime defence at major firms is among the better-paid contentious work. Sector and market drive the difference.
What is white-collar crime practice?
White-collar (or financial-crime) practice handles fraud, bribery, corruption, regulatory enforcement and corporate investigations. It is a higher-paid, document-heavy corner of criminal law that overlaps with compliance and corporate work.
What skills matter most in criminal law?
Persuasive advocacy, deep knowledge of criminal procedure and evidence, sound judgment, and resilience - the work is contentious, fast-moving and often carries serious human consequences.
