A chronology is one of the most useful documents you can bring to a lawyer: a single, readable record of what happened, in date order, with the facts only.
Most people start it the wrong way round.
The mistake
They try to decide what matters while they're still gathering.
It feels efficient. You know the story, so you go looking for the messages that tell it. But you end up with a curated list that quietly reflects what you already believed. Anything that didn't fit the story you started with never made it onto the page, and some of it might have mattered more than what did.
If you decide the shape of the story first, you'll go looking for it, and you'll find it whether or not it's there.
Instead: cast the widest net first
Go through every channel, including email, WhatsApp, text messages, any co-parenting app and letters, and log everything that might matter, however small.
Don't categorise yet. Don't judge yet. Just capture.
Six columns
A simple spreadsheet is enough:
- Date
- Channel: email, WhatsApp, text, letter, in person
- A neutral one-line summary: what was said or done, not what you think of it
- A loose category tag: school, handover, health, money, holiday and so on. Make these up as you go.
- A working note on why it might matter
- Anything else: a file reference, a follow-up or a question to check
Keep the summary column scrupulously neutral. "Asked to move Saturday handover to 2pm" not "tried to cut my time again". Your interpretation can live in the working note, clearly separate from the facts.
Do it in chunks
A few months of one channel at a time. Then the next few months, then the next channel.
Trying to do years of everything in one sitting is how people give up on day two. Little and often gets it finished.
Then let the patterns appear
Once the messy log has some substance, look at it as a whole:
- Which categories are dense? If a third of your rows are tagged "school", that's telling you something.
- Which single dates show up in more than one channel? A text, an email and a call on the same day usually marks something significant.
- Which topics have enough material to deserve their own table? That's when you split them out.
The categories should emerge from what's actually there, not from the list you'd have written in advance.
From messy to tidy
Only now do you write the clean chronology: one readable document, in date order, fact only, drawn from the messy log.
Every line in it can be traced back to a row, and every row back to a source. That's what makes it something a lawyer can rely on rather than a story they have to check from scratch.
Mark what you haven't reviewed
One last habit. If you've worked through eight months and not yet the other four, say so in the document: "March–June: not yet reviewed."
An unstated gap reads as "nothing happened there." A labelled gap is honest, and it protects you if something turns up later.
Log first, interpret second. The order isn't arbitrary.
General information, not legal advice. Court process differs between countries and regions; check anything that matters to your case with a qualified lawyer where you live.
Chapter 6 of the workbook takes you from the messy log to a finished chronology. Worksheet D is the six-column catch-all log described here, and Worksheet C is the clean chronology you build from it.
