Case closure is a quality-control point. It is the moment to make sure the record still explains what was requested, what was done, what was found, what was delivered, and what was left unresolved.
Confirm the assignment is complete
Return to the original assignment and any documented scope changes. Confirm that the work performed matches the authority actually given and that the case record identifies any work that was requested but not completed.
- Original assignment and client objective are identifiable.
- Material scope changes are documented.
- Work outside scope is not presented as though it were authorized.
- Any discontinued or declined work is explained where it matters.
Resolve or record open items
A case does not need every uncertainty eliminated before it can close. It does need unresolved items to remain visible. Record unavailable witnesses, missing records, unverified leads, incomplete coverage, client decisions not to authorize additional work, and other limitations that affect the final result.
Review evidence and provenance
Check that important evidence can still be identified and traced to its source. Working copies, excerpts, redactions, crops, OCR text, or other derivatives should remain distinguishable from the item originally received or acquired.
- Important evidence has a stable identity.
- Source and acquisition information is retained where relevant.
- Received source material remains available when required.
- Derivatives can be traced back to their source.
- Material corrections or changes remain understandable.
Review notes and chronology
Case notes and chronology should make sense without fresh memory. Check dates, names, significant decisions, investigative activity, evidence references, and corrections. Remove ambiguity where a future reviewer would otherwise need the investigator to explain what a shorthand entry meant.
Finalize reporting
Confirm that the final report answers the authorized assignment, distinguishes fact from analysis, addresses material contradictory information, states significant limitations, and does not claim more certainty than the record supports.

Confirm client deliverables
Record what was delivered, when, and in what form when that matters to the engagement. Keep internal working material distinguishable from material intended for the client or another recipient.
Close billing records
Review case charges, approved expenses, invoices, credits, taxes where applicable, and any outstanding balance. A closed investigative record is easier to understand when the business record connected to the matter is also complete.
Apply retention and access rules
Closure does not automatically mean deletion. Apply the retention, confidentiality, contractual, legal, licensing, and client requirements that govern the matter. Preserve restricted or sensitive records with appropriate access controls.
Perform a final reconstruction test
Select several important conclusions and work backward through the case. Can another qualified reviewer identify the assignment, relevant facts, supporting evidence, source material, significant decisions, contradictory information, limitations, and final client deliverables without relying on your memory?
If the chain breaks, fix the record before treating the matter as finished.
