Lawyer side income takes a few shapes: freelance legal work — research and writing for other attorneys, or contract attorney engagements — plus teaching, bar tutoring and writing, and businesses with nothing to do with the law.
What separates a lawyer side hustle from anyone else's second income is the framework around it: the conduct rules as your state has adopted them, whatever your firm's rules say about outside work, and your malpractice coverage.
Run those checks before the first invoice, not after.
Legal side work: freelance research, writing and contract work
The closest-to-home option is doing more of the work you already do, for someone else.
Freelance legal side work means research memos, briefs, motions and drafting projects done for other attorneys and firms — legal work picked up on the side of a day job.
The other broad shape is contract attorney work: engagements taken directly with a firm or through a staffing arrangement.
Our freelance attorney work guide covers how those engagements run.
Two structural questions are worth settling before the first engagement.
First, how you will be engaged: as a temporary worker paid hourly, or as an independent shop billing the firm.
Under federal law, that pay structure does not settle overtime status on its own — the Department of Labor's regulations (29 CFR 541.304) treat an employee who holds a valid license and is actually engaged in the practice of law as an exempt professional, so the federal salary-level and salary-basis requirements do not apply to that lawyer, and an hourly-paid lawyer on a W-2 can still be exempt.
State law can differ; check the rules where you work with your state labor agency.
Second, how the fee flows if you bill as your own shop: ABA Model Rule 1.5(e), in the model text, allows a fee division between lawyers in different firms only if it is proportional to the services each provides (or each assumes joint responsibility), the client agrees in a confirmed writing that includes each share, and the total fee is reasonable.
States adopt their own versions of the model rules.
Teaching, bar tutoring and legal writing
Legal knowledge also sells in forms that never touch a client file.
Adjunct teaching and practitioner courses put practice experience in front of law students.
Bar exam tutoring helps applicants prepare for the exam itself.
Writing options include CLE materials, practice guides, articles for legal publishers and legal journalism.
These run on expertise you already have, outside the billable hour — the checks run from whatever your firm's rules say about outside work to the marketing rules, covered below and in the next section.
One marketing rule to check before you list your services: under Ohio Rule 7.4(e) — the ABA moved the specialist rule to Model Rule 7.2(c) in 2018, but Ohio still numbers it 7.4, so cite your own state's version — a lawyer may not state or imply that they are a specialist unless they are certified as a specialist and the communication names the certifying organization.
A tutoring profile, a course landing page or a freelance listing that calls you a "litigation specialist" is exactly where that rule bites.
And if a writing sample would come out of client work, the confidentiality duty reaches it — that rule is in the next section.
Ethics rules and employer policy set the limits
Start with the rule aimed straight at side businesses.
Under Ohio Rule 5.7 — the state's adopted version of ABA Model Rule 5.7 — a lawyer is subject to the conduct rules when providing law-related services that are not distinct from legal services, or through an entity the lawyer controls, unless customers are told the services are not legal services.
Read against a side business, that structure says a legal-adjacent venture cannot be renamed out of the rules, and that when law-related services run through an entity the lawyer controls, the conduct rules attach unless customers are told the services are not legal services.
Non-legal businesses raise different questions.
On the title itself, New York State Bar Ethics Opinion 1147 (March 23, 2018) treats using "Esq." in connection with a non-legal business conducted in New York as a question of misleading communications, not a licensed title — a lawyer not admitted in New York may use it if care is taken to avoid confusion about the lawyer's status.
On confidences, the confidentiality rule (Ohio Rule 1.6(a), the state's version of ABA Model Rule 1.6) bars revealing information relating to a client's representation unless the client gives informed consent, disclosure is impliedly authorized to carry out the representation, or a listed exception applies — and it covers reusing client work product as a writing sample.
On money, Ohio Rule 1.15(a), based on ABA Model Rule 1.15, requires client funds to be kept separate from the lawyer's own money in a trust account carrying a fiduciary title; IOLTA programs operate in all 50 states, D.C., Puerto Rico and the U.S. Virgin Islands.
Whether a given side engagement triggers the trust rules as adopted in your state is a question for your state bar's ethics counsel.
Then there is the employer.
Where the side-work answer lives while you are employed is firm-specific — your employment agreement, your handbook, any outside-activities process your firm uses — so read yours before you launch.
The ethics rules speak to the covenant on the way out: ABA Model Rule 5.6(a), in the model text, bars partnership, employment or similar agreements that restrict a lawyer's right to practice after leaving, except agreements about retirement benefits.
"Can my firm restrict where I practice after I go" and "may I tutor on nights and weekends now" are different questions with different rulebooks.
Model text is not the rule you are bound by
Insurance and conflicts before the first side client
Malpractice coverage is where side work quietly goes wrong.
The one state-level mandate our research verified is Oregon's: every bar licensee in private practice with a principal office in Oregon must carry coverage through the Professional Liability Fund — in 2026, $300,000 per claim/aggregate plus a $75,000 claims-expense allowance, for a $3,500 assessment.
Oregon also reaches remote practice: since Jan 1, 2025, Oregon Rule of Licensure 5.3 has required lawyers practicing in Oregon from a principal office elsewhere to carry coverage substantially equivalent to PLF primary coverage.
Elsewhere, this page's research did not verify other states' mandatory or disclosure rules, so the check is your own: if you practice under a firm's policy, ask whether it reaches work for side clients at all; if you carry your own policy, ask your broker or carrier the same question before you quote the engagement.
Remote side work has a geography problem of its own.
ABA Formal Opinion 495 (Dec 16, 2020) says a lawyer may practice their licensing state's law while physically in a state where they are not admitted, if that state has not deemed the practice unauthorized and the lawyer does not hold out a local office or offer local services — and under the opinion, putting local contact information on websites, letterhead or business cards in the non-licensing state would improperly establish a local office.
The opinion is advisory, and states may differ.
Finally, conflicts.
A side client is a client, and taking one raises conflicts questions of its own — whose interests are adverse, and what prior work touches the same parties.
This page's research did not verify the conflicts rules state by state, so treat the specifics as a question rather than a given: run the engagement past your firm's conflicts process where you have one, or your state bar's ethics counsel, before you say yes.
Where to find attorney jobs
Side income can be a probe: some of it stays on the side, and some of it turns out to be the career.
Whether you want a firm whose work matches the engagements you enjoy picking up, or a main role that leaves room for the side practice, the open market is what a job board shows you in real time.
