How to Write a Timeline for a Court Case

A timeline for a court case, often called a legal chronology, lists the events behind a dispute in the order they happened. It helps a judge, a mediator or your own attorney follow what happened and when, and building one often turns up gaps in the record while there is still time to fill them.

This article covers the practical work of putting one together. It is not legal advice. Courts and judges can have their own rules on what they accept and in what format, so ask your attorney or check with the court clerk before you file anything.

What to include

Start from your documents rather than your memory. Go through emails, letters, contracts, medical records, police reports, texts and court papers one at a time, and write down each dated event as you find it. Then add what you remember but cannot yet document, marked so you can tell the two apart.

Keep events that bear on the issues in the case, along with the background needed to understand them. A marriage date matters in a divorce, and a hire date matters in an employment dispute. An event that does not help anyone decide anything can usually be left out, because every extra entry makes the important ones harder to find.

How to word each entry

Each entry needs three things:

The date. Use the most exact date you can support, and add a time if the order of events on one day matters.
What happened. Write one short, neutral statement of fact, naming who did what.
The source. Give the exhibit number, document name or page, or the witness who can confirm it.

Leave your argument for somewhere else. Compare these two entries:

Argumentative: "March 3, 2025: The landlord ignored my complaint again, as usual."
Neutral: "March 3, 2025: Tenant emailed the landlord about the broken heater (Exhibit 4). No reply is in the file."

The second one is harder to dispute, and the reader can still draw the conclusion you want them to draw.

If you are unsure of a date, say so instead of guessing. An approximate date that is labeled as approximate is much easier to defend than an exact date that turns out to be wrong.

Check it before you rely on it

Read the finished timeline against the source documents, entry by entry, and confirm that each date and exhibit number matches. Then read it from start to finish and look for anything that does not add up, such as a reply dated before the message it answers, or a long gap where you would expect some activity. How to Make a Chronology has more on collecting events source by source and settling conflicting dates.

Building one in Preceden

Create a timeline and name it after the case, then add each entry as an event. A few features fit this kind of work:

Notes for the source. Keep the event's name short and put the exhibit number and any detail in its Notes field.
Approx. for uncertain dates. Check Approx. next to a date you cannot confirm so the timeline marks it as approximate. If you only know the month, type just the month and year, such as March 2025. Supported Date Formats lists everything else Preceden reads.
Layers for each strand. Add a layer for each party or issue, such as "Plaintiff", "Defendant" and "Court Filings", so you can see how the strands line up.
The Bulk Editor for long lists. The Bulk Editor gives you a spreadsheet-style view for adding or correcting many entries at once.

To bring the timeline to a hearing or attach it to a document, save it as a PDF. You can also share a link with your attorney, or, on a Pro plan, invite someone to edit it with you.

Case details are often sensitive, so check who can see the timeline before you share it. A timeline you start from scratch is private until you change that. A draft made with Create With AI starts as Secret URL, so anyone with its link can open it. The status next to the timeline's name shows which one applies, and Adjust Timeline Visibility explains each option.

The free plan allows up to 10 events on each timeline, and most cases need more than that. Our paid plans lift the event limit. If you work on cases regularly, Preceden for legal cases shows how lawyers use it.
