Investigation Case Log Template | CaseWorks

An investigation case log is a dated record of investigative work performed during a matter. It answers what work was done, when it was done, who performed it, what it related to and what follow-up resulted. It is not the complete investigation case file.

If you need the broader structure for intake, chronology, leads, sources, interviews, actions and review, use the Investigation Case File Template guide.

What should an investigation case log include?

Useful fields can include activity date/time, activity type, concise description, person responsible, related lead or source, status, outcome and resulting follow-up.

Case log vs. case file vs. timeline

Case log: records investigative work performed. Case file: contains the broader organized record. Timeline: records material events in the underlying matter. Keeping these purposes separate prevents work dates from becoming confused with event dates.

Keep entries concise and traceable

Use the log as an index of meaningful case activity. Reference the detailed interview, source, lead, correspondence or task record when additional information exists rather than duplicating entire records.

Record outcomes and resulting work

If an activity generates a new lead, records request or action, record the outcome and move unresolved work into the appropriate tracker. Avoid entries such as “worked on case” that do not explain what occurred.

Use consistent activity categories

Depending on the workflow, categories might include document review, interview, contact attempt, source review, research, lead follow-up, correspondence or case review. Consistency makes a long-running log easier to scan.

Frequently asked questions

Is a case log the same as an investigation timeline?
No. The case log records investigative activity; the timeline records events relevant to the underlying matter.

Is a case log the complete case file?
No. It is one component of the broader file and should reference detailed records where appropriate.

Should every small action be logged?
The appropriate level of detail depends on the workflow and applicable requirements. Meaningful work, outcomes and resulting follow-up are generally more useful than trivial entries.
