How Litigators Use AI in Daily Practice
AI support touches nearly every stage of litigation. The sections below explain how AI improves each task with practical detail and examples that reflect real workflows.
Early Case Assessment
Early case assessment shapes the direction of a matter. A litigator needs clear facts, timelines, and risks before planning discovery or drafting motions. AI shortens this phase by summarizing large sets of documents and highlighting key events.
AI reviews emails, contracts, transcripts, and other records, then produces structured summaries with parties, actions, and dates. This helps you build an early understanding of strengths, weaknesses, and factual gaps before you spend hours on manual review.
Example:
A litigator uploads an initial production of emails and HR documents into a secure platform. The tool highlights repeated complaints, escalating issues, and communication gaps. The litigator builds an early outline for potential claims and prepares questions for custodians.
Useful outputs include timelines, fact summaries, and lists of recurring topics.
Reviewing Opposing Counsel Filings
Opposing filings reveal strategy. A litigator must understand the arguments, the authority behind those arguments, and any changes from earlier positions. AI support speeds this review.
AI extracts key points in an opposition or reply brief. AI highlights unsupported statements, missing citations, or shifts from earlier arguments. Comparing two filings becomes faster when AI shows differences in structure or emphasis.
Example:
A litigator uploads an opposition brief. The tool identifies three central arguments and shows that one argument contradicts a position taken earlier in a meet and confer letter. The litigator uses this inconsistency during preparation for a reply brief.
Useful outputs include argument lists, comparison summaries, and flagged inconsistencies.
Drafting Litigation Documents
Drafting forms a large portion of a litigator’s workload. Motions, oppositions, replies, complaints, and letters require structure and clarity. AI helps create early drafts that shorten the writing cycle and reduce time spent organizing ideas.
AI prepares outlines for factual sections and issue lists for argument sections. A litigator edits these drafts, adds authority, checks accuracy, and adjusts tone. The draft becomes a starting point rather than a finished document.
Example:
A litigator prepares a motion to compel. The tool produces a draft structure with sections for background, deficiencies in responses, and requested relief. The litigator inserts citations, adds case-specific facts, and finalizes the argument.
Useful outputs include draft outlines, argument structures, and formatted text blocks.
Deposition Preparation
Depositions require thorough preparation. A litigator must understand documents, prior testimony, and potential inconsistencies. AI support accelerates this analysis.
AI reviews transcripts, identifies contradictions, highlights key passages, and organizes topics for questioning. AI also suggests cross examination paths based on conflicts between documents and testimony.
Example:
A litigator uploads three transcripts from the same witness. The tool highlights inconsistent statements across the transcripts and links each inconsistency to the relevant page. The litigator prepares questions that focus on these gaps.
Useful outputs include topic outlines, contradiction lists, and suggested question paths.
Discovery Requests and Objections
Discovery shapes the factual record. Drafting and responding to requests requires precision, proportionality, and knowledge of local rules. AI support improves clarity during this stage.
AI drafts interrogatories, requests for admission, and document requests tailored to the issues in a case. AI also reviews opposing requests and highlights vague, broad, or burdensome language. A litigator then adjusts the drafts and prepares targeted objections.
Example:
A litigator uploads a set of document requests from the opposing party. The tool highlights broad language such as “any document related to” and suggests narrower alternatives. The litigator uses these insights to prepare objections and propose revisions.
Useful outputs include narrowed language, draft objections, and lists of improper terms.
Privilege Review and Redaction
Privilege review protects sensitive information. This stage requires accuracy and careful attention to context. AI improves efficiency by identifying patterns that suggest privilege or confidentiality.
AI scans documents for attorney communication, internal analysis, financial records, or personal data. AI suggests redactions and helps prepare privilege logs with consistent formatting.
Example:
A litigator reviews a large email thread with mixed recipients. The tool flags emails that include legal advice from in-house counsel. The litigator confirms each flagged message and prepares a privilege log entry.
Useful outputs include flagged items, draft redaction suggestions, and formatted privilege log entries.
Evidence and Exhibit Management
Trials and hearings require organized evidence. Exhibits need to be grouped, labeled, and accessible. AI helps build structure around this process.
AI groups documents by topic, extracts key passages, and assists with the creation of exhibit lists. AI also supports binder preparation by identifying important documents and linking them to testimony or issues.
Example:
A litigator uploads a set of contracts, emails, and financial records. The tool groups them by issue, such as breach, damages, or notice. The litigator uses these groups to build exhibit lists for a hearing.
Useful outputs include grouped exhibits, highlighted excerpts, and draft exhibit lists.
Chronologies and Timelines
Chronologies support all stages of a matter. A timeline shows how events developed and which actions influenced the dispute. AI builds these timelines faster than manual review.
AI extracts dates, parties, actions, and locations from documents. AI organizes them in chronological order and highlights gaps where evidence appears incomplete. A litigator adjusts the timeline to reflect confirmed facts.
Example:
A litigator uploads emails, HR memos, and performance reviews. The tool produces a timeline that shows how documented warnings progressed toward termination. The litigator uses this timeline to prepare for a deposition.
Useful outputs include chronological charts and lists of factual gaps.
Strategy and Case Theory
Strong strategy requires clear identification of strengths and weaknesses. AI helps by summarizing factual patterns and outlining possible arguments on both sides.
AI lists favorable and unfavorable facts, identifies missing evidence, and provides counter arguments. This supports preparation for motions, mediation, and trial planning.
Example:
A litigator uploads a summary judgment motion and the key documents. The tool outlines three strong arguments for the moving party and highlights two factual weaknesses. The litigator adjusts the case strategy based on these insights.
Useful outputs include argument maps, counter argument lists, and risk summaries.
Expert Witness Support
Expert testimony influences the outcome of many cases. Reports often contain complex analysis. AI support reduces review time and helps identify weaknesses.
AI summarizes expert reports, highlights unsupported statements, and compares multiple expert opinions. AI also suggests cross examination questions based on gaps in methodology or conclusions.
Example:
A litigator uploads two expert reports on valuation. The tool shows differences in assumptions and identifies one conclusion that lacks support in the data. The litigator uses this point during depositions.
Useful outputs include summary charts, comparison tables, and question outlines.
Client Communication and Reporting
Clients expect clear and timely updates. AI support helps create short summaries for clients with no legal background.
AI prepares drafts of status reports, deposition summaries, and hearing updates. A litigator edits these drafts to ensure accuracy and adds strategic recommendations.
Example:
A litigator uploads hearing notes. The tool produces a three paragraph summary. The litigator adjusts the language and sends the update to the client.
Useful outputs include clean summaries and structured reports.
Discovery Workflows
Discovery involves continuous coordination. AI helps organize document sets, identify sensitive content, and support motion practice.
AI clusters documents by issue and highlights patterns across custodians. AI also prepares drafts for motions to compel or motions for protective orders based on the noted issues.
Example:
A litigator loads an early production set. The tool highlights a pattern of missing attachments in certain email rows. The litigator uses this insight to request supplemental production.
Useful outputs include cluster maps, draft motions, and issue summaries.
Trial Preparation
Trial requires organized preparation across witnesses, exhibits, and argument structure. AI helps produce early drafts and supports consistent organization.
AI prepares witness outlines, suggests question paths, and organizes exhibits by issue. AI also drafts early structures for opening statements, closing arguments, jury instructions, and verdict forms.
Example:
A litigator uploads witness statements and key documents. The tool produces an outline with topics for direct and cross examination. The litigator refines the outline and prepares questions.
Useful outputs include outlines, draft argument structures, and exhibit packages.
Hearing Preparation
Hearings often arrive with short notice. AI support helps a litigator prepare clear, focused arguments.
AI identifies the core issues, prepares argument outlines, and lists likely questions based on similar cases or motions. AI also supports preparation of short memos or supplemental filings.
Example:
A litigator uploads a brief and key documents to prepare for a motion to strike. The tool highlights the single issue driving the dispute and produces a clear outline for oral argument.
Useful outputs include argument outlines and lists of anticipated questions.
Legal Research Validation
AI does not replace verified research. AI supports validation and comparison work.
After a litigator identifies cases through verified sources, AI summarizes holdings, compares multiple decisions, and highlights differences across jurisdictions. This helps refine arguments without reducing accuracy.
Example:
A litigator uploads citations from an opposition brief. The tool compares the holdings and highlights a key difference in one case that favors the litigator’s position. This insight shapes the reply brief.
Useful outputs include comparison tables and summary notes.
Project and Deadline Management
Litigation runs on deadlines. AI support helps track these deadlines and organize tasks.
AI calculates dates based on local rules, creates task lists for drafting or discovery actions, and tracks progress across team members. This support reduces oversight risk.
Example:
A litigator enters a filing date for a summary judgment motion. The tool calculates opposition and reply deadlines and generates a checklist for the drafting cycle.
Useful outputs include calendars and organized task plans.
Billing and Timekeeping
Accurate billing supports firm operations. AI helps convert raw notes into clear, structured entries.
AI highlights vague language, identifies missing entries, and prepares weekly billing summaries. A litigator reviews the output and confirms accuracy.
Example:
A litigator uploads handwritten notes. The tool produces clean time entries with clear descriptions. The litigator edits the entries and logs the time.
Useful outputs include draft time entries and compliance checks.
Knowledge Management for Litigation Teams
Litigation teams rely on shared knowledge. AI helps store and retrieve past work product.
AI organizes templates, summarizes past case outcomes, and creates internal guides for recurring issues. This support improves consistency across teams and speeds onboarding for new litigators.
Example:
A litigator uploads a set of prior motions from similar cases. The tool summarizes common arguments and formats them into a practice guide.
Useful outputs include guides and template libraries.
Compliance and Risk Management
Sensitive information requires strong safeguards. AI helps identify material that demands protection.
AI flags privileged communication, personal information, and other sensitive content. AI supports redaction and controlled access workflows. A litigator confirms each action.
Example:
A litigator prepares a production. The tool flags a set of internal messages with legal advice. The litigator confirms the flags and prepares the privilege log.
Useful outputs include risk alerts and redaction drafts.
Negotiation and Settlement Preparation
Settlement decisions rely on structured analysis. AI helps organize evidence and draft materials for negotiation.
AI prepares summaries for mediator statements, outlines for demand letters, and lists of strengths and risks. AI also supports preparation of ranges based on factual patterns.
Example:
A litigator uploads key documents related to damages. The tool produces a structured summary of the evidence that supports the settlement position. The litigator uses this summary during mediation.
Useful outputs include negotiation summaries and structured demands.
