TL;DR: A court-ready chronology is complete, cited, and honest about precision - and building one by hand is days of reading and transcription. The AI workflow: assemble the case file once in a library that OCRs scans, let the Timeline Builder read every date and deadline into a single chronology with each event categorised, summarised, flagged if it is a deadline, and cited to its page; verify and annotate; then work the timeline in four views and export to PDF, Word, Excel, or calendar. The machine does the extraction; you supply the narrative judgment.
Ask experienced litigators where a case was won and the answer is often the same: in the chronology. The sequence of who knew what, when, is where limitation arguments live, where inconsistencies in the other side's story surface, and where your theory of the case either holds together or falls apart. Yet chronologies are traditionally built by the most junior person on the matter, by hand, under time pressure - the exact conditions that produce transposed dates and missed events. This guide walks through building a chronology with AI that is faster to produce and easier to defend.
Why chronologies decide cases
A chronology is not an administrative artefact; it is the case's factual spine. Limitation and prescription turn entirely on dates. Notice provisions, cure periods, and contractual deadlines turn on sequence. Credibility turns on whether a witness's account fits the documented order of events. And settlement leverage often turns on being the side that can produce, instantly, the documented answer to what happened between March and June.
Court-readiness adds three requirements to mere existence. The chronology must be complete - built from every document in the file, not the ones somebody remembered to read. It must be verifiable - every entry traceable to a document and page, because opposing counsel will check. And it must be honest about precision - an event known only to the month must say so, because a guessed day that turns out wrong taints the entries around it. Manual builds struggle with all three at volume; they are exactly what the machine is good at.
Step 1: Assemble the case file once
Start by getting the whole file into Judicio's File Library: pleadings, correspondence, contracts, invoices, board minutes, exhibits - drag in folders or ZIPs, or import from Google Drive, OneDrive, SharePoint, or iManage. The library reads 25+ formats up to 1 GB per file, OCRs scanned papers automatically so an old fax or a stamped court filing becomes searchable, flags duplicates, and extracts key facts from each document - including key dates with deadline flags - the moment it processes.
Completeness at this stage is what buys completeness in the chronology. The events the timeline can find are the events in the file, so the discipline is to load everything, including the documents nobody has read yet - especially those.
Step 2: Extract every date, categorised and cited
Select the case documents and run the Timeline Builder. It reads every date and deadline across multiple files into a single chronology, and for each event records the things a chronology needs: a summary of what happened, a category (let Judicio suggest the categories worth tracking, start from one of 100 timeline templates, or define your own - filings, correspondence, payments, meetings), a deadline flag where the date is one, and a citation to the passage and page it came from with a short note on why it matters.
Two design choices matter for litigation. Deadlines are flagged distinctly, so limitation dates and procedural deadlines are impossible to lose in the noise of ordinary events. And precision is honest: a document that says in March 2024 produces an event dated to the month, not to an invented day. The result is a first-draft chronology in minutes that would have taken days by hand - built from the entire file, not a sample. For the broader litigation workflow, see AI litigation support.
Step 3: Verify, correct, and annotate
The extracted timeline is a draft, and the workflow treats it as one. Work through the events - starting with the deadline-flagged ones - and open each citation to read the passage in context. Correct anything the extraction misread, annotate events with context the documents do not carry, and add entries the file only implies: the undocumented phone call, the meeting known from testimony. Extracted events keep their citations; your additions are visibly manual, which preserves the evidentiary distinction between what the documents show and what the team believes.
This pass is where the hours you saved on extraction get reinvested, and it is a better use of them: instead of hunting for dates, you are reading the key passages of the case in sequence, which is precisely how case theories form. You can also chat with the timeline - ask what happened in a window, or where two accounts diverge - to pressure-test the story as it takes shape.
Step 4: Work the timeline in four views
A chronology answers different questions depending on how you look at it, so the Timeline Builder gives you four views and a set of filters:
| View | What it shows | Use it for |
|---|---|---|
| Table | Every event in sequence with details | The working master chronology |
| Visual timeline | Events plotted along an axis | Spotting clusters, gaps, and pace - and showing them |
| By document | Events grouped by source file | Checking what each exhibit contributes |
| By category | Events grouped by type | Following one thread - payments, notices, filings |
Filters cut the chronology by category, date range, or deadlines only - the last one turning the case file into a deadline list in a click. The gaps are often the payoff: a silent six weeks in the correspondence view is either a hole in your evidence or a hole in the other side's story, and you want to know which before they do.
Step 5: Export for court, counsel, and calendar
Chronologies serve different audiences, and the export options match. Export to Word or PDF - with citations for the version counsel and the court will test, or without for a client-facing summary. Export to Excel when the chronology feeds a damages model or a disclosure schedule. Export to Calendar (.ics) so every extracted deadline lands in the team's diary with its source attached - closing the classic gap between knowing a deadline exists in the file and having it where anyone will see it in time.
Because every extracted event carries its citation through the export, the bundle version of the chronology is self-proving: any entry challenged at a hearing traces to a page in seconds.
How Judicio helps: chronology as a by-product of the file
In Judicio the chronology is not a separate transcription project; it falls out of the case file you already loaded. The File Library ingests and OCRs the file once; the Timeline Builder reads every date and deadline across multiple files into one cited, categorised, deadline-flagged chronology with four views and honest precision; Document Review and the Review Matrix run on the same files when the matter needs clause-level analysis; and shared projects keep the whole litigation team on one record with roles and an activity trail.
See the litigation solution page for how disputes teams combine these tools across a matter's life.
Getting started with Judicio
Take a live matter - or a closed one whose chronology you trust - load the file into the library, and run the Timeline Builder. Compare the extracted chronology against the hand-built one: coverage, accuracy, and the hours each took. Check the deadline filter against your diary while you are at it.
