How Do You Shepardize a Case? A Complete Guide to Legal Citation Verification
Shepardizing a case is a fundamental skill in legal research that ensures the validity and current status of court decisions. This leads to this process involves checking the citational history of a judicial opinion to determine whether it remains good law or has been overturned, modified, or undermined by subsequent rulings. For law students, paralegals, and legal professionals, mastering this technique is essential for building accurate arguments and avoiding reliance on obsolete precedents.
What is Shepardizing?
Shepardizing refers to the systematic review of citations associated with a legal decision to assess its continued authority. In practice, named after Frank Shepard, who founded the commercial citation service in 1879, this method allows researchers to trace how a case has been treated in other courts. The process reveals whether a decision has been affirmed, reversed, criticized, or ignored, providing critical context for legal analysis.

Steps to Shepardize a Case
Step 1: Gather Key Information About the Case
Before initiating the Shepardization process, collect essential details about the case, including:
- Case name (e.In real terms, g. , *Brown v.
These elements form the basis for accurate citation searches and prevent confusion with similarly named cases.
Step 2: Access a Legal Database
Modern Shepardizing requires digital tools, as manual methods are obsolete. Primary platforms include:
- Westlaw: Uses KeyCite to check citations
- LexisNexis: Employs Shepard’s citations
- Bloomberg Law: Offers similar citational analysis
Most law libraries provide free access to these databases, though individual accounts may be required for off-campus use.
Step 3: Search for the Case
Enter the case details into the database’s search function. Consider this: use precise terms to avoid irrelevant results. As an example, searching "Miranda v. Arizona" will yield the correct case without confusion from similar names.
Step 4: Locate the Citations Section
Once the case appears in search results, figure out to its record. Most databases display a separate tab or section labeled "Citations," "History," or "Treatment." This area contains all cases that have referenced the target decision.
Step 5: Analyze Positive and Negative Citations
Positive citations indicate support for the case, such as:
- Affirmations by higher courts
- Quoting in appellate decisions
- Adoption in legislative history
Negative citations signal challenges to the case’s authority, including:
- Reversals or modifications
- Criticism in judicial opinions
- Overruling by superior courts
Pay special attention to negative treatment indicators, as these often signal diminished legal force.
Step 6: Check for Subsequent Developments
Review the most recent citations first, as newer cases carry greater weight in determining current legal status. Look for:
- Recent appellate or Supreme Court decisions
- Legislative changes affecting the case’s premise
- Statutory amendments impacting its reasoning
Step 7: Verify the Case’s Current Status
After reviewing all citations, determine whether the case remains viable precedent. A case may still be cited frequently but lose authority if higher courts have explicitly questioned its reasoning or applied it narrowly.
Tools and Resources for Shepardizing
LexisNexis Shepard’s Citations
LexisNexis provides comprehensive citational analysis through its Shepard’s service. Users can input a case citation to receive a detailed report showing:
- Negative history (cases undermining the decision)
- Positive history (supporting cases)
- Treatment by jurisdiction
- Key numbers system for topic-based searches
Westlaw KeyCite
Westlaw’s KeyCite offers similar functionality, labeling cases with red (negative), blue (positive), and yellow (neutral) flags. It also tracks:
- Judicial treatment in subsequent cases
- Legislative or regulatory changes
- News articles referencing the decision
Free Alternatives
Some platforms offer limited citational checks:
- Google Scholar provides basic citation counts and links to citing cases
- Court websites often include citational data for recent decisions
- Law school libraries may provide access to premium databases
Common Challenges in Shepardizing
Identifying the Correct Case
With thousands of cases sharing similar names, precision is critical. Always verify:
- Jurisdiction (federal vs. state courts)
- Year of decision
- Parties involved
Interpreting Citation Symbols
Legal databases use symbols to denote citation types:
- Aff’g (affirmed)
- Rev’g (reversed)
- Dist’g (distinguished)
- Conf’g (confirmed)
Understanding these abbreviations helps quickly assess a case’s treatment.
Keeping Up with Updates

Frequently Asked Questions
Why is Shepardizing important in legal research?
Shepardizing ensures reliance on valid precedent, preventing wasted effort on overturned or undermined cases. It strengthens legal arguments by confirming a decision’s continued relevance and authority.
Can I Shepardize a case manually?
While possible, manual Shepardizing is time-consuming and error-prone. Digital tools automate citation tracking and provide instant access to vast legal databases.
How often should I Shepardize a case?
For active cases or ongoing legal matters,
Accurate legal precedents remain the cornerstone of judicial coherence, requiring sustained vigilance to preserve their integrity. But through rigorous Shepardizing, practitioners ensure consistency amid shifting dynamics, reinforcing trust in the system’s foundational principles. And while challenges persist, such as precision in identification and adaptation to new rulings, the process remains vital for maintaining relevance and authority. In real terms, continuous engagement with these practices upholds the system’s stability, guiding future decisions with clarity and reliability. Such efforts collectively sustain the legacies that define legal continuity. Thus, the deliberate practice of Shepardizing stands as a cornerstone, ensuring the enduring impact of judicial decisions.
