Legal case chronology template: organise facts for your lawyer

A legal case chronology template helps turn scattered messages and memories into an account someone else can check. You do not need to decide which legal argument is right before starting. The immediate task is to show what happened, where the information came from and which details remain uncertain. This guide prepares a working document for a lawyer, rather than a court filing.

The Brest Bar recommends writing a chronology before an initial consultation. Our template develops that organisational idea into a practical worksheet. It is not a statement of procedural requirements in France, the UK, the US or any other jurisdiction.

Define the question before building the timeline

Write down why you are seeking advice, where the events happened and what you want to understand. Give the people and organisations consistent labels. Choose a starting and ending point for your review, and explain that choice. Expand the period if an earlier event provides necessary context; do not narrow the account just to make it support your preferred interpretation.

Keep your aim separate from a legal conclusion. “I want to understand why these documents differ” leaves room for investigation. “This proves I must win” assumes the answer. Include information that challenges your account as well as information that appears to support it.

Give every document a recoverable reference

Assign short identifiers such as D01, D02 and D03. Keep a separate index connecting each identifier to a filename and location. Use working copies for notes and retain the original files. Preserve the context of message exchanges, and distinguish when an event happened from when a document was written or received.

Describe what a document actually supports. An email may show that a statement was sent without establishing that the statement is true. Avoid labelling every file conclusive evidence. Where a row relies on memory, say so; where a document is missing, record the gap rather than filling it with an assumption.

Copy this legal case chronology template

Use one row for one event, with six fields. A spreadsheet or a text document can both work. The useful feature is traceability, rather than a particular file format.

Date and accuracy | Neutral description of event | Person or organisation | Document and location | Basis of knowledge | Outstanding question.

[Exact or approximate date] | [One specific action] | [Consistent label] | [D01, page or message reference] | [Document / direct observation / memory / someone else's account] | [What needs checking].

Spell out the month or state your date format. “2026-05-04, 4 May” illustrates a format, not an event from a real dispute. If time matters, retain the time zone shown by the source. A note written today about an earlier conversation should not make today's date look like the date of the conversation.

Leave uncertainty visible

Sorting a timeline does not turn an approximate date into an exact one. Record a range, or write “date not confirmed”, and explain the basis of any estimate. If two records disagree, keep both references and make the disagreement a question for the consultation. Quietly selecting the more helpful version removes information the lawyer may need.

Do not put remembered words in quotation marks as though you have an exact transcript. Use a clearly labelled paraphrase when that is what you have. Separate the observation from your explanation of why it happened; a sequence of events alone does not establish a causal connection.

Use AI to organise a limited set of notes

Before sharing material with an AI service, remove personal information that is unnecessary for the task and check whether you may share the remaining material. You can test the structure with blank fields instead of uploading a full case file. Keep the underlying originals outside the generated working draft.

Prompt: “Organise only these notes into the six-field chronology. Preserve the document identifiers and references I supply. Do not invent dates, people, quotations, causes or sources. Mark missing information as pending and contradictions as questions. Distinguish documented facts, memories and interpretations. Do not calculate legal deadlines or draft a witness statement for court.”

Check every generated row against its source. A fluent table can still misread a date or connect unrelated statements. Legal Assistant AI lets you ask about documents and prepare questions for a consultation. Verify the output and ask your lawyer how any generated text should be used.

Prepare a version another person can follow

Open each document reference, check the uncertain dates and look for facts you may have left out because they are uncomfortable. Add your priority questions and a list of missing records. Ask the lawyer which delivery format and communication channel to use.

Bring any communication containing a date or requested action to the professional's attention without waiting for a perfect timeline. This worksheet does not calculate deadlines or choose a procedure. It is ready for discussion when a reader can follow the account, locate the supporting material and see precisely what is still unknown.
