What Paralegals Can and Can't Do: Supervision and the Unauthorized Practice Line
The short answer
A paralegal performs substantive legal work — research, drafting, document and case management — but does so under the supervision of a licensed attorney, who remains responsible for the work. Acts reserved to attorneys, including giving legal advice, representing a client in court, and setting fees, sit outside the role. California's paralegal statute is one of the clearest written examples of where that line falls, and it spells out prohibited activities expressly in Business and Professions Code sections 6450–6456.
Step 1: Define the term "unauthorized practice of law"
The phrase you will meet constantly in coursework is unauthorized practice of law, often shortened to UPL. It refers to doing something that is legally reserved to licensed attorneys. The Wex legal encyclopedia from Cornell Law School is a free, citable place to read how the concept is explained, and it is worth reading early rather than late — the boundary shapes daily habits, not just exam answers.
The definitions matter because the consequences are not symmetric. Delegating research to a paralegal is routine. A paralegal answering a client's "so what should I do?" directly is not.
Step 2: See the work paralegals genuinely do
The supervised side of the line is broad, not clerical. The U.S. Department of Labor's profile for paralegals and legal assistants lists the occupation's tasks in detail, and they are recognizably substantive: investigating facts, researching law, preparing and organizing documents and exhibits, maintaining case files, and assisting with case preparation. Specialized software and document systems appear in the same profile, which is a good hint about what to learn before interviews.
A useful mental model, in order:
1. The attorney owns the professional judgment and the client relationship.
2. The paralegal develops the material that judgment is built on.
3. The attorney reviews, signs, and takes responsibility.
Step 3: Read a statute as the worked example
Most states do not license paralegals the way they license attorneys, so written definitions are not uniform across the country. California is the instructive case because it put a definition and a list of prohibitions in statute. Reading the actual text of sections 6450–6456 teaches you three things at once:
- What qualifications a state may require for someone to use the title.
- Which acts are expressly withheld from paralegals.
- That continuing education can be written into a definition, not just recommended by an association.
The exception to generalize carefully around: California's text governs California. It is a model for how such rules are written, not a nationwide rulebook. Our walkthrough of what California's statute requires goes through that text in order.
Step 4: Learn the courtroom vocabulary before you need it
Much of the boundary is expressed in procedural language — pleading, discovery, deposition, motion, docket. The Glossary of Legal Terms from the United States Courts is the official federal reference for these words and a better study tool than a flashcard app, because it defines the terms as the courts use them.
Step 5: Translate the line into working habits
The practical version of this topic is a short list of reflexes that experienced paralegals develop:
- Describe what a document says; let the attorney say what it means for the client.
- Route questions that call for judgment to the supervising attorney rather than answering them.
- Identify your role clearly in client communications, so nobody mistakes you for counsel.
- Keep the supervising attorney's review in the workflow, not at the end as a formality.
- When a rule is state-specific, read the state's own text before relying on a summary.
