AI legal research for paralegals - what you can do and where the lines are
By LegiMatch Research Team · Published October 14, 2026 · 3 min read
Short answer: Paralegals can use AI research tools for a lot of the groundwork: finding candidate cases, summarizing opinions, checking citation format and building tables of authorities. The work must be done under a lawyer's supervision, and the lawyer stays responsible for it (Model Rule 5.3). A paralegal can't give legal advice to clients. Every case and quotation an AI tool produces has to be read and verified before anyone relies on it.
This article is general information, not legal or ethics advice. State rules on paralegal work vary.
The framework
| Rule or source | What it means for paralegals using AI |
|---|---|
| ABA definition of paralegal | A paralegal does "specifically delegated substantive legal work for which a lawyer is responsible." |
| Model Rule 5.3 | Lawyers must make reasonable efforts to ensure nonlawyer assistants' conduct is compatible with the lawyer's professional obligations. |
| Model Rule 5.5 | Prohibits assisting the unauthorized practice of law. Nonlawyers can't give legal advice or represent clients unless a specific rule allows it. |
| ABA Formal Opinion 512 (2024) | Firms using generative AI should set clear policies and train lawyers and staff on proper use, including confidentiality and verification. |
| NALA and NFPA codes | Professional codes for paralegals stress working under lawyer supervision, protecting confidences and not practicing law. |
Tasks AI tools suit well
- First-pass case finding: describe the facts and the issue to get candidate cases for the lawyer's review.
- Summaries: short summaries of long opinions, each checked against the opinion itself.
- Citation clean-up: spotting format errors and missing pinpoints, and building a table of authorities.
- Brief checking: listing every authority in a draft so each can be pulled and verified.
- Organizing research: grouping cases by issue, jurisdiction or outcome in a matter folder.
Tasks that need the lawyer
- Deciding which authorities to rely on and how to frame the argument.
- Anything the client sees as advice: emails, memos, or answers to "what should I do?"
- Final review and signature on anything filed with a court.
- Deciding what client information may go into a tool, under the firm's policy and Rule 1.6.
Handing AI-assisted research to the lawyer
Every case an AI tool suggests must be opened and checked before anyone relies on it. The step-by-step checklist is in our article on AI-invented case citations and court sanctions. The paralegal-specific part is the hand-off: make it easy for the lawyer to see what was checked.
A short research note works well:
| Column | What to write |
|---|---|
| Authority | Case name and full citation |
| Found by | AI tool, keyword search, or citing reference |
| Verified | Opened from a reliable source, citation details match, quotation checked word for word |
| Good law | What you checked and the date |
| Supports | The point it's cited for, with the pinpoint page |
| Flags | Anything uncertain: dicta, a split, a different jurisdiction, an unpublished opinion |
This saves the supervising lawyer time, shows the supervision Rule 5.3 expects, and helps if a court rule requires disclosure of AI use.
Protecting client information
- Use only firm-approved tools.
- Leave out names and identifying details when the research question doesn't need them.
- Don't paste client documents into personal or free AI accounts.
- Follow the firm's rules on uploading briefs, contracts or records.
Frequently asked questions
Can a paralegal use AI for legal research?
Yes, as delegated work under a supervising lawyer, within the firm's policy. The lawyer is responsible for the final work product.
Is it unauthorized practice of law if a paralegal uses AI to answer a client's legal question?
Giving a client legal advice is generally the practice of law, whether or not AI is involved. Paralegals should pass legal questions to the supervising lawyer.
Who is responsible if an AI tool produces a fake citation?
The lawyer who files the document is responsible to the court. Firms also have supervision duties under Rules 5.1 and 5.3, so a verification step for staff is expected.
Should a paralegal tell the lawyer when AI was used?
Follow the firm's policy. In practice, noting which results came from AI and what was verified helps the lawyer review efficiently, and helps with any court rule that requires disclosure of AI use.
