A criminal defense attorney represents people and organizations accused of crimes, from the first court appearance through plea negotiations, trial and, when a case calls for it, sentencing and appeal.
It is a client-service practice as much as a courtroom one: retained defense attorneys build their own caseload, manage their own investigations and answer to their clients directly.
This guide walks through the day-to-day work, the settings, the skills and the career paths.
What does a criminal defense attorney do day to day?
The core of the job is simple to state: a criminal defense attorney defends a client who has been accused of a crime, and everything else in the role exists to serve that defense.
On an active file, the attorney evaluates the charges and the evidence, builds a strategy, and keeps the client informed at each stage of the case.
The building blocks of the work:
- Case evaluation and investigation. Reading police reports, charging documents and discovery, working with investigators and expert witnesses, and identifying the weaknesses in the government's evidence.
- Pretrial motion practice. Written and oral advocacy over what evidence comes in, what stays out, and how the case moves toward resolution.
- Plea discussions. Negotiating with prosecutors and advising the client on the options, while making sure the final decision belongs to the client.
- Trial. Jury selection, cross-examination, objections, opening statements and closing arguments when a case is tried rather than resolved earlier.
- Sentencing and post-conviction work. Advocacy after a plea or a verdict and, in some practices, appeals and record-relief matters.
- Client communication. Explaining the process, setting expectations and staying reachable between court dates — a defense client is navigating the case from the outside, and the attorney is the person who explains what happens next.
The mix shifts with the court calendar.
A week built around hearings looks nothing like a trial week, and negotiation-heavy files reward a different rhythm than trial-bound ones.
Private practice adds a business layer on top of the legal work: intake consultations with prospective clients and their families, fee agreements, and the referrals and reputation that feed a client base.
Where do criminal defense attorneys work and who employs them?
Private criminal defense takes several shapes, and the setting you practice in shapes the job as much as the subject matter does.
- Solo practices and small defense firms. The attorney is the practice: appearing across a region's courtrooms, managing client relationships directly, and running intake, billing and marketing alongside the legal work.
- Larger firms with defense practices. Some multi-lawyer firms field criminal defense teams, including for white-collar matters, regulatory investigations and internal corporate investigations.
- Court-appointed work. Courts assign some defense matters to private attorneys through appointment systems whose details are set locally.
- Public defense. Public defenders do defense work inside a government office — a distinct employer and its own career path.
The settings also overlap.
An attorney may carry retained clients and appointed matters side by side, and careers can cross between private practice and public defense.
What skills and credentials does a criminal defense attorney need?
The credential that starts the career is the law license.
Criminal defense attorneys practice in the courts of the state where their cases are heard, and each state sets its own admission requirements.
Whether a state also offers an additional specialist credential in criminal law was outside the scope of our research — the state bar can tell you if it runs a certification program.
The skills the job runs on:
- Trial advocacy. Jury selection, witness examination and argument are the craft of the role, and courtroom experience is how that craft develops.
- Negotiation. Negotiating with prosecutors is a standing part of defense work, and doing it well shapes a client's options.
- Case and calendar management. Defense attorneys juggle concurrent matters in courts that run on their own schedules, and managing that calendar is a skill in its own right.
- Client counseling. Clients can arrive frightened, angry or overwhelmed, and translating a case into plain, honest advice is part of the service.
- Evidence work. Reviewing discovery, directing investigators, working with experts, and spotting what the government's case leaves out.
- Legal writing. Written advocacy — motions and briefs — shapes a case long before trial begins.
Attorneys building toward defense work also invest in courtroom time early, because trial skill is the part of the job that is hardest to learn from a desk.
What does a typical caseload or workload look like?
Start with an honest caveat: our research found no public benchmark for how many cases a criminal defense attorney carries.
The federal data our sources describe treats all lawyers as a single occupation, with no split of attorney employment by practice area, so we have no verified count of how many attorneys practice criminal defense, let alone how many matters each one carries.
Treat any precise caseload statistic you encounter with caution.
The workload is driven by the kind of matters a practice carries.
The charge level, whether files are headed toward trial or toward negotiation, the court's calendar, and how much support the firm provides — investigators, paralegals, legal assistants — all shape how many matters an attorney can handle well.
Court dates set the rhythm of the week.
Appearances, hearings and trial blocks pull the attorney out of the office, and the between-court work — discovery review, motions, client meetings, negotiations — fills the rest.
Since no published number can answer the caseload question for a specific firm, ask it directly in interviews: how many active matters attorneys carry, how a case is staffed, and how trial time is shared between senior and junior lawyers.
How does the role compare with nearby attorney roles?
Public defenders sit on the same side of the courtroom with a different employer: defense work inside a government office, with clients who arrive through the court system rather than a private retainer.
Private defense attorneys are retained by their clients or take appointed matters, and they carry the business side of a practice on top of the legal work.
Prosecutors work the other side of the same courtroom, presenting the government's case.
The two roles draw on a similar toolkit — evidence, negotiation, trial advocacy.
The licensing picture also separates defense work from some other practice areas.
Federal immigration regulations define an attorney as a member in good standing of the bar of the highest court of any U.S. state, territory or D.C., so a license from any one state is enough for the federal side of immigration practice, while state-law advice still calls for that state's own license.
Our research found no equivalent for criminal defense: the practice runs through the courts where cases are pending, and who may appear is governed by that jurisdiction's own admission rules — confirm the specifics with the bar admission authority in your state.
Against other private practice areas, what marks defense work is the opponent and the stakes.
The government brings the case, and the outcome shapes a person's record, freedom and future.
How do you become a criminal defense attorney?
The short version: an undergraduate degree, law school, and admission to the bar in the state where you intend to practice.
Admission rules are set state by state and they change, so build your plan around the requirements the admitting authority in your state publishes rather than around secondhand summaries.
Inside that path, aim your effort at the skill defense work turns on: courtroom time.
Pursue the settings that put you in a courtroom — clinics, judicial clerkships, defense offices and junior associate roles with real appearances.
Verify the requirements with your state's board
How much do criminal defense attorneys make?
Our research found no clean salary figure for criminal defense specifically.
In the federal data our sources describe, lawyers are one occupation rather than a set of practice-area series, so we have no official criminal-defense figure to quote.
In practice, earnings track experience, geography, the court system a practice works in and the mix of retained, appointed and public-defense work.
When you compare opportunities, compare the whole structure — client base, appointed work, benefits — not just the headline number.
Where to find criminal defense attorney jobs
LawFirmHires lists criminal defense attorney jobs at law firms, and the listing page is the fastest way to see who is hiring right now.
As you compare openings, weigh the things that actually shape a defense career:
- Case mix — the kinds of charges, and whether the practice sits in state courts, federal courts or both
- Client base — retained work, court-appointed work, or a mix of both
- Trial expectations — how courtroom time is shared between senior and junior attorneys
- Support — investigators, paralegals and legal assistants who take work off your desk
- Client development — who brings in the work today, and how you would learn to
Defense is also a locally networked career: county and state bar associations, criminal defense sections and the lawyers you appear alongside are all part of that network.
