A chronology is only as good as its sources. When a witness pushes back on a date at deposition, “it is in our timeline” is not an answer. The answer is the Bates number and the page.
Most litigation teams still build chronologies in a spreadsheet or a table in a word processor. That works for a small file. It breaks once productions arrive in rounds, several people add entries, and nobody can say where row 214 came from.
This guide covers what case chronology software should do for a litigation team, the eight features worth paying for, and the questions to ask before you buy.

Why spreadsheet chronologies break down
A spreadsheet is a fine place to start a chronology. It is a poor place to keep one through discovery:
- Rolling productions. Every new production means re-reading, re-sorting and re-checking the whole sheet.
- No source on the line. An entry without a Bates cite has to be found again before it can go into a brief or a deposition outline.
- One version per reviewer. Two people working from two copies end up with two chronologies.
- Conflicts stay hidden. When two documents give different dates for the same event, a spreadsheet keeps whichever one was typed last.
What is case chronology software?
Case chronology software, also called litigation timeline software or legal chronology software, builds a dated record of events from the documents in a matter. The better tools read the documents for you, pull out dates, people and events, and link every entry back to the page it came from.
That makes it different from a general timeline maker. A litigation chronology is evidence: each entry has to hold up when someone asks where it came from.
8 features to look for in case chronology software
Spreadsheet vs general AI vs case chronology software
Three common ways litigation teams build a timeline, and how each one handles the parts that matter in court:
| What you need | Spreadsheet | General AI chatbot | Case chronology software |
|---|---|---|---|
| A source for each entry | Typed by hand, if at all | Often missing or hard to verify | Linked to the document and page |
| A new production arrives | Re-read and re-sort | Re-upload and re-prompt | Added to the same matter |
| Two documents disagree | The last edit wins | May pick one without saying | Both kept and flagged |
| The whole team works on it | Copies by email | One person's chat history | One matter for the team |
| Client data | Depends on where the file is saved | Check the terms before uploading | Should be documented: SOC 2, no training on client data |

Questions to ask in a demo
- Can I click from any entry to the exact page it came from?
- What happens when two documents disagree on a date?
- How do I add a new production without rebuilding the chronology?
- Can I filter by witness and by issue, and export with the citations kept?
- Can the demo run on a sample file that looks like my cases?
- Is there a SOC 2 Type II report, and is client data ever used to train models?
The right frame: A chronology is evidence, not a list of dates. Every entry should answer two questions at once: what happened, and where the record says so. Software that only answers the first question leaves the second one to you.
How NexLaw builds a case chronology
Upload the production and ChronoVault builds the chronology. Every entry links to its source document, with Documents, Event, Evidence and Entities views of the same record.
The matter overview flags unfavorable facts and discovery gaps, so conflicts in the chronology get reviewed before a deposition, not during it.
Case analysis, risk analysis with the evidence quoted, and cross-examination outlines, all built from the same record.
NexLaw Essential is $2,999 per year per license, with no seat minimum.
