How to Prepare a Case Chronology: A Practical Guide for Law Students and Junior Lawyers

A case chronology arranges relevant events by date and connects each entry to its supporting record. For law students and junior lawyers, preparing one means reading documents carefully, distinguishing competing accounts and identifying what still needs verification. A useful chronology lets the reviewing lawyer move from an event to the underlying document quickly, while keeping uncertainties visible.

This guide explains how to build a working chronology from agreements, correspondence, notices and court papers, with a hypothetical example you can adapt.

Establish what the chronology needs to cover

Before extracting dates, confirm the purpose of the assignment. A lawyer preparing for a hearing may need the procedural history. Someone reviewing a commercial dispute may need the transaction, performance, correspondence and subsequent proceedings.

Clarify the relevant issues, documents available, expected level of detail and deadline. A useful opening message is:

“I will prepare a chronology covering the transaction and subsequent proceedings, with document and page references. Please let me know if you would like particular attention to any issue.”

A working chronology can contain detailed source notes and unresolved questions. A list of dates prepared for filing must follow the applicable court requirements. For example, the Supreme Court’s Advocate’s Checklist specifically addresses a brief list of dates and events, along with the chronological arrangement of annexures. Check the relevant filing requirements before adapting an internal document for court.

Give every source a reliable identity

Start with a short document inventory. Record each document’s description, date, page count and any obvious problem, such as missing attachments or an illegible signature.

For an unnumbered collection, assign simple working identifiers: D1 for the agreement, D2 for an email and D3 for a notice. Preserve existing annexure numbers and bundle references where available.

An entry such as “Email, page 4” becomes difficult to trace when several emails are combined. “D7, email from buyer to supplier dated 16 May, PDF page 2” identifies the source more precisely.

Check whether printed page numbers differ from the PDF viewer’s page count. State which numbering system you use. Where necessary, record both: “Bundle page 42; PDF page 47.”

Keep the originals intact and work from copies. Add bookmarks or searchable text where useful, while checking extracted text against the scan.

Separate the event date from the document date

One document can contain several dates with different meanings.

An email dated 12 May might report that goods were dispatched on 11 May. A notice dated 20 May might have been posted on 22 May, with delivery recorded on 25 May. An agreement signed on 3 May might specify a delivery deadline of 10 May.

Capture each relevant event separately and explain what the date represents.

For the dispatch example, write:

“Supplier stated in its email dated 12 May that dispatch took place on 11 May.”

This preserves the distinction between the reported event and the record supporting that account.

Use an unambiguous format such as “11 May 2026”. If a document records only “May 2026”, retain that level of precision. Flag an ambiguous entry such as “05/06/26” for verification rather than silently choosing an interpretation.

Use a table that connects events, sources and questions

A practical working format has four columns: date, event, source and verification note. The final column gives you somewhere to record uncertainty without burying it in the narrative.

Hypothetical example: A buyer and supplier disagree about when goods were delivered. All documents, identifiers and events below are fictional; dates fall within the same year.

Date	Event	Supporting source	Verification note
3 May	Parties entered into an agreement specifying delivery by 10 May.	D1, agreement, page 2, clause 4	Check for amendments or extensions.
11 May — reported	Supplier stated that the goods were dispatched on this date.	D2, supplier’s email dated 12 May, page 1	Dispatch record unavailable.
12 May — disputed	Supplier claimed delivery occurred on this date.	D3, supplier’s email dated 15 May, page 1	Buyer gives a different receipt date.
14 May — disputed	Buyer stated that it received the goods on this date.	D4, buyer’s email dated 16 May, page 1	Obtain delivery acknowledgement.
20 May	Buyer’s demand notice bears this date.	D5, notice, page 1	Posting date requires verification.
25 May	Courier tracking records delivery of the parcel associated with the notice.	D6, tracking record, page 1	Match the consignment number to the dispatch record.

The table identifies a concrete next task: obtain the delivery acknowledgement and reconcile the competing accounts. It also keeps the notice date separate from posting and delivery.

Attribute disputed facts accurately

Choose wording that reveals the status of an assertion.

“Buyer alleged that the goods were defective” identifies a party’s position. “Goods were defective” presents a conclusion. Similarly, “Supplier stated that payment remained outstanding” accurately describes a communication without deciding the payment dispute.

The Supreme Court’s Handbook for Law Clerks advises distinguishing disputed facts from agreed or established facts and using attribution when describing disputed matters. That approach is useful when preparing a working chronology for legal review.

Where a court has made a finding, identify the court, order date and relevant paragraph. Record any subsequent order affecting that finding where relevant to the assignment.

Avoid treating the existence of a document as conclusive proof of everything it says.

Turn missing information into specific follow-up tasks

Keep undated material in a clearly marked section until its position can be established. Where the available record supports only an approximate period, explain the basis.

For example:

“Undated letter refers to the meeting of 8 June. Its own date remains unverified.”

Distinguish “the document was not supplied” from “the event did not happen”. If an email refers to an attachment that is missing, record the gap.

Make follow-up requests precise:

“Please obtain the attachment to the email dated 12 May and the delivery acknowledgement identifying the recipient.”

If a missing or disputed date could affect limitation or another legal deadline, flag it promptly for the supervising lawyer’s review. Any deadline calculation needs its own checked legal basis.

Verify the chronology in both directions

First, check every entry against its source. Confirm the date, names, amount, description and page reference.

Then review the documents again against the completed chronology. This second pass helps identify relevant events you overlooked, including an extension request, a reply or an interim order.

Include material events that complicate the client’s account. For internal case preparation, those entries help the reviewing lawyer assess the record and prepare responses.

Keep individual rows focused. Where several events occurred on the same day, separate them when their order matters. Use recorded times where available and flag uncertainty where the sequence cannot be established.

Hand over the chronology with a clear status note

Add the matter name, preparation date, version and scope at the top. State which records you reviewed and identify any outstanding documents.

Hypothetical handover note:

“Attached is the working chronology prepared from documents D1–D18. Each entry includes a source reference. The principal unresolved issue is the delivery date: the supplier states 12 May, while the buyer states 14 May. The delivery acknowledgement and the attachment to the email dated 12 May remain outstanding. References use PDF page numbers.”

When new records arrive, update the chronology, preserve the previous version and explain material corrections. This allows the reviewing lawyer to understand both the current timeline and the evidence that changed it.
