Why Opposing Counsel Research Changes Your Strategy
Knowing who you are up against changes how you litigate. An opposing attorney who consistently files aggressive early discovery motions tells you to prepare your privilege logs early and your objections carefully. An attorney with a pattern of early settlement in cases where liability is clear tells you to establish liability quickly and push for an early mediation. An attorney who rarely takes cases to trial but has an excellent record when they do tells you that settlement discussions are worth pursuing seriously. None of this intelligence is available from the pleadings alone.
Opposing counsel research is not surveillance — it is using publicly available information to make better strategic decisions. Every experienced litigator does it. The question is how systematically and how thoroughly.
Start with Published Decisions
The most accessible source of opposing counsel intelligence is published case law. Search for the attorney's name as counsel of record in legal databases — Westlaw, LexisNexis, Google Scholar, and AI-powered tools like CaseMatch AI — and review the decisions that appear. Look for patterns in the types of cases they handle, the motions they file, the arguments that succeed or fail for them, and the jurisdictions and courts where they are active.
Published decisions are a biased sample — most cases settle without published opinions — but they reveal the attorney's legal capabilities and tendencies in the cases that go the distance. An attorney whose cases always settle before summary judgment and an attorney with multiple published summary judgment victories are different litigation risks.
PACER and State Court Dockets
Federal court filings through PACER and state court electronic dockets provide a much fuller picture than published decisions alone. Docket searches by attorney name reveal the volume and type of their practice, the cases they have filed and defended, how long their cases take to resolve, and how frequently they go to trial versus settle. This data is more complete than published decisions and gives you a realistic view of their overall litigation portfolio.
For cases in the same court where your matter is pending, docket research also reveals the attorney's relationships with particular judges — how frequently they appear before the same bench and with what results.
AI-Powered Opposing Counsel Research Tools
Purpose-built AI tools for opposing counsel research aggregate published decisions, docket data, and outcome patterns into structured profiles. CaseMatch AI's opposing counsel research feature allows attorneys to search by name and jurisdiction to surface the cases an attorney has appeared in, the outcomes of those cases, and the patterns in their motion practice and litigation strategy.
This type of aggregated research, which previously required hours of manual database searching, is now available in minutes — giving litigants at all firm sizes access to the opposing counsel intelligence that was previously available only to well-resourced practices with dedicated litigation support staff.
What to Do With What You Find
Opposing counsel research should directly inform your litigation planning. If they have a pattern of filing motions to compel over minor discovery disputes, plan your discovery responses to be unimpeachably complete. If they rarely depose expert witnesses, consider whether that creates a strategic opportunity in your expert preparation. If they have a strong record before a particular judge, assess whether that judge's tendencies favor your position or theirs on the key issues in your case.
The goal is not to build a dossier — it is to make better strategic decisions with more complete information. The same discipline of evidence-based decision-making that governs good legal research should govern litigation strategy.
