The problem
In litigation, the timeline is everything. The sequence of events determines who is liable, what defences are available, what evidence is relevant, and how the case will be argued. A clear, accurate timeline is the foundation of good case analysis.
Building that timeline from the raw material of a litigation file is painstaking work. A typical commercial dispute might involve hundreds of emails, letters, contracts, invoices, and attendance notes spread across years. Extracting the relevant events, establishing the correct sequence, and presenting them in a usable format takes hours.
The problem compounds over time. As a case progresses, new documents arrive and the timeline needs updating. If it is not maintained rigorously, the team ends up with an outdated document that nobody trusts, and everyone reverts to digging through the original documents.
A well-maintained timeline is also a client communication tool. Clients who understand the sequence of events are better able to give instructions and make decisions about their case.
The system
Step 1: Gather and sort the source documents
Compile all the key documents in the case into a single folder, sorted chronologically where possible. Key source types include:
- Correspondence (letters and emails)
- Contracts and their key dates
- Invoices and payment records
- Meeting attendance notes
- Any relevant external events (regulatory decisions, market events)
For complex cases, upload these to NotebookLM.
Step 2: Extract the timeline from documents (NotebookLM or Claude)
For cases where you can upload documents to NotebookLM:
"Working from these documents, extract all events with dates and create a chronological timeline. For each event, include: the date, what happened, which document records this event, and the significance of this event to the dispute."
For smaller cases where you can paste document summaries into Claude:
"I am going to paste summaries of the key documents in a litigation matter. As I paste each one, extract any dated events and add them to a running timeline. After I have pasted all the documents, compile the full timeline in chronological order."
Then paste your document summaries one by one.
Step 3: Analyse the timeline for legal significance (Claude)
Once you have the raw chronological timeline, use Claude to analyse it:
"Here is the timeline of events in a [type of dispute — e.g., contract breach claim]. Review this timeline and:
- Identify the key events that are likely to be disputed between the parties
- Note any gaps in the timeline where important events should have occurred but are not documented
- Identify any limitation or time-bar issues based on the dates
- Highlight any events that appear inconsistent with each other
- Suggest any further documents or evidence that would strengthen or clarify the timeline
Note: I will verify your analysis against the actual documents. This is a preliminary assessment only."
Step 4: Create the client timeline (Claude)
"Using this timeline, create a plain-English version for the client. Include only the events that are directly relevant to their case and explain why each event matters. Write for a non-lawyer who is anxious about their case and needs a clear picture of what happened and when. Keep it to one page."
The results
Before: 3 to 5 hours to build an initial timeline from a complex file, with ongoing maintenance falling behind as new documents arrived.
After: 1 to 2 hours for the initial build, with a structured document that is easier to maintain as the case progresses.
The analysis step (Step 3) adds genuine value beyond time saving. The gap analysis and inconsistency flags often surface things that a human reader focusing on individual documents might miss. One solicitor using this workflow identified a critical limitation issue during the timeline analysis that had not been spotted in the initial file review.
The client timeline output is also useful for witness preparation and client meetings: a clear chronological narrative helps clients recall events in the right sequence and identify documents they might have overlooked.
