Free Investigation Timeline Template
Use this free, no-signup worksheet to organize material events in chronological order and keep the source, verification status and follow-up visible.
This resource is designed for lawful professional research, case organization and responsible fact-finding. It can be used as a simple starting point before moving into a more detailed case-management workflow.
Timeline fields
| Date / Time | Event | Source | Verification | Notes / Follow-Up | |
|---|---|---|---|---|---|
How to use it
- Record the date and time of the event when known.
- Describe the event factually and concisely.
- Identify where the information came from.
- Mark whether the event is verified, reported, inferred or still unknown.
- Record conflicts, gaps or follow-up instead of silently resolving uncertainty.
Good documentation habits
- Separate what happened from when you learned about it.
- Keep source attribution with material facts.
- Preserve conflicting accounts for later review.
- Turn unresolved questions into explicit follow-up actions.
- Collect, retain and share only information you are authorized to handle.
When the free timeline is no longer enough
The free timeline works well when your main need is chronological organization. Move to the $15 Timeline & Lead Tracker when events are creating unresolved leads and you need to track who owns each follow-up, its status, the next action, due date and outcome.
Move to the $79 Investigation & Case Management System when the work has expanded beyond chronology and leads into intake, planning, source documentation, interviews/contacts, actions and case review.

Investigation timeline FAQ
What should an investigation timeline include?
At minimum, capture the event date and time when known, a factual description, the source of the information, its verification status, and any notes or follow-up created by the event.
Should reported and verified events be treated the same?
No. A useful chronology preserves the distinction. CaseWorks uses verification context so reported, inferred, unknown and verified information do not become indistinguishable simply because they appear on the same timeline.
What if two sources conflict?
Preserve the conflict and document the sources rather than silently selecting one version. The disagreement itself may create a follow-up question or lead.
What is the difference between a timeline and a lead tracker?
A timeline organizes what happened and when. A lead tracker organizes what still needs to be checked, who owns the follow-up, and what happened as a result. Using both connects chronology to action.
Is this an official investigative form?
No. It is a general-purpose organizational resource from CaseWorks Digital and is not an official government or law-enforcement form.
