The Research Revolution
A junior associate at a mid-size firm described her old research process: start with a broad Westlaw search, wade through dozens of results, read case after case, take notes, organize by relevance, and compile a memo. For a complex issue, this could take an entire day or more.
Her new process: she starts with AI to build a research map—identifying the key legal principles, relevant statutes, and likely lines of authority. Then she uses traditional databases to verify, deepen, and cite-check. Total time: roughly 2-3 hours for work that used to take 8.
The key word in that story is “then.” AI doesn’t replace legal databases. It makes you dramatically more efficient at using them.
The AI Research Methodology
Here’s the structured approach that maintains rigor while saving time:
Phase 1: Frame the Question
Before touching any tool, define exactly what you’re researching:
Help me frame a legal research question:
ISSUE: [Describe the legal issue in plain language]
JURISDICTION: [Federal, state, specific court]
AREA OF LAW: [Contract, tort, criminal, IP, employment, etc.]
CLIENT SITUATION: [Anonymized facts—no names, no identifying details]
SPECIFIC QUESTIONS:
1. [First legal question]
2. [Second legal question]
I need to identify:
- Governing statutes or regulations
- Key case law (landmark and recent)
- Any circuit splits or unsettled areas
- Secondary sources for background
Help me refine this into a precise research query.
AI helps you think through the research question systematically, identifying sub-issues and research angles you might not have considered initially.
Phase 2: Build the Research Map
Create a research map for this legal question:
QUESTION: [Your refined research question]
JURISDICTION: [Jurisdiction]
Organize the research by:
1. STATUTORY FRAMEWORK
- Governing federal statutes
- Relevant state statutes
- Applicable regulations
- Recent legislative changes
2. CASE LAW HIERARCHY
- Supreme Court / highest court decisions
- Circuit / appellate court decisions
- Notable district / trial court decisions
- Recent decisions (last 3 years)
3. KEY LEGAL STANDARDS
- Elements of the cause of action / defense
- Burden of proof
- Applicable tests or frameworks courts use
4. SECONDARY SOURCES
- Leading treatises on this topic
- Relevant law review articles
- Practice guides
5. OPEN QUESTIONS
- Unsettled areas of law
- Circuit splits
- Emerging trends
NOTE: I will verify ALL citations independently.
Provide enough identifying detail for me to locate each source.
This research map becomes your roadmap for targeted database searching.
Quick check: How does this compare to your current research process? Most lawyers start searching and follow threads organically. The structured map approach is more comprehensive and more efficient.
Phase 3: Deep Dive with Targeted Research
Take the research map to your legal databases. Now you’re not searching blindly—you have specific targets:
- Verify every statute and case AI identified
- Read the actual cases (not just AI summaries)
- Shepardize or KeyCite to check current validity
- Look for cases AI may have missed using traditional search strategies
- Note any AI-generated citations that don’t check out
Phase 4: Synthesize and Analyze
I've completed my research on [topic]. Here are my verified findings:
STATUTES: [List confirmed statutes with citations]
KEY CASES: [List verified cases with actual holdings]
STANDARDS: [Legal tests and frameworks confirmed]
Help me:
1. Organize these authorities by relevance to my specific question
2. Identify the strongest authorities for [position]
3. Identify the strongest counter-arguments
4. Spot any gaps in my research
5. Draft an analytical framework I can use in my memo
Research Memo Drafting
Once your research is verified, AI helps you organize it into a coherent memo:
Draft a legal research memo outline:
QUESTION PRESENTED: [Your specific legal question]
BRIEF ANSWER: [Your conclusion based on research]
JURISDICTION: [Jurisdiction]
VERIFIED AUTHORITIES:
[List your verified statutes and cases]
Structure the memo as:
I. Question Presented
II. Brief Answer
III. Statement of Facts (I'll provide the facts)
IV. Discussion
A. Governing legal framework
B. Analysis of issue 1
C. Analysis of issue 2
D. Counter-arguments and responses
V. Conclusion
For the Discussion section, show how each authority
supports or challenges the analysis.
Draft the legal reasoning, not just case summaries.
Statutory Analysis
AI is particularly helpful for parsing complex statutory schemes:
Analyze this statute for my research:
STATUTE: [Citation and relevant text]
QUESTION: [What I need to understand about this statute]
Provide:
1. Plain language summary of what the statute requires
2. Key defined terms and their significance
3. Elements that must be met
4. Exceptions or safe harbors
5. Relationship to other statutes in this area
6. How courts have interpreted ambiguous provisions
7. Recent amendments and their effect
I will verify all interpretive citations independently.
Regulatory Research
Map the regulatory framework for [topic]:
AGENCY: [Relevant regulatory agency]
JURISDICTION: [Federal, state]
Identify:
1. Enabling statute
2. Implementing regulations (CFR citations)
3. Relevant guidance documents
4. Recent enforcement actions
5. Pending rulemaking
6. Key compliance deadlines or requirements
I will verify all citations against official sources.
Research for Different Practice Areas
Litigation Research
Research the legal standard for [claim/defense]:
JURISDICTION: [Court]
CLAIM/DEFENSE: [Specific cause of action]
I need:
1. Elements (what must be proven)
2. Burden of proof
3. Leading cases establishing the standard
4. How courts have applied this in similar fact patterns
5. Common defenses and their standards
6. Relevant evidentiary considerations
7. Statute of limitations
All citations require my independent verification.
Transactional Research
Research the legal requirements for [transaction type]:
JURISDICTION: [Jurisdiction]
TRANSACTION: [Type of deal/agreement]
Identify:
1. Statutory requirements (filings, approvals, formalities)
2. Regulatory requirements (licenses, notifications)
3. Common legal issues in this type of transaction
4. Standard market terms and conditions
5. Recent trends in deal structuring
6. Key risk areas and mitigation strategies
Employment Law Research
Research employer obligations regarding [issue]:
JURISDICTION: [Federal + state]
EMPLOYER SIZE: [Number of employees]
INDUSTRY: [Industry if relevant]
Identify:
1. Applicable federal laws (FLSA, FMLA, ADA, Title VII, etc.)
2. State-specific requirements
3. Key employer obligations
4. Employee rights
5. Enforcement mechanisms and penalties
6. Recent case law developments
7. DOL or EEOC guidance
The Verification Workflow
This cannot be overstated: every AI-generated legal citation must be verified. Here’s the systematic approach:
| Step | Action | Tool |
|---|---|---|
| 1 | Check the case exists | Westlaw / Lexis |
| 2 | Verify the citation format | Bluebook |
| 3 | Confirm the holding matches AI’s summary | Read the actual case |
| 4 | Check it’s still good law | Shepardize / KeyCite |
| 5 | Verify the relevance to your issue | Your professional judgment |
Build a simple tracking document:
CITATION VERIFICATION LOG
| AI Citation | Exists? | Holding Accurate? | Still Good Law? | Relevant? | Notes |
|------------|---------|-------------------|-----------------|-----------|-------|
Exercise: Research a Legal Question
Pick a legal question relevant to your practice:
- Frame the question using the Phase 1 prompt
- Generate a research map using Phase 2
- Verify at least 5 citations from the AI output against a legal database
- Note which citations were accurate and which weren’t
- Synthesize your verified research into a one-page analysis outline
- Track your time compared to your usual research process
Key Takeaways
- AI-assisted research follows four phases: Frame, Map, Verify, Synthesize
- Never skip verification—AI can generate fabricated citations that look completely real
- Structure your research with a map before diving into databases
- AI understands conceptual relationships, finding authority that keyword searches might miss
- Always anonymize client facts before inputting into AI tools
- Maintain a citation verification log for every AI-assisted research project
- AI saves the most time on the research compilation phase, not the verification phase
