Chain of Custody Form: Free Template & How to Use

A chain of custody form is a single document that records who handled a piece of evidence, when, how, and whether anything changed, from collection through production. It's the written backbone of a defensible chain of custody, and the field-by-field record a court looks to when authenticity is challenged.

Below is a free chain of custody template you can adapt for electronic evidence, plus a guide to filling out every field correctly.

What a Chain of Custody Form Must Capture

A complete form answers who, what, when, where, and how for each item of evidence. At a minimum, include these fields:

How to Fill Out a Chain of Custody Form

1. Open the record at collection, not after. Create the entry the moment you collect, so the log is contemporaneous, not reconstructed from memory.
2. Generate and record the hash immediately. Capture the MD5 or SHA-256 value at the point of collection. This is the single most important field.
3. Log every transfer and access. Each time the data moves or someone interacts with it, add a dated, attributed line. No silent handoffs.
4. Re-verify the hash at each major step. After ingestion and before production, confirm the value still matches and note it.
5. Retain the completed form with the matter file. The record should travel with the production and survive the life of the matter.

Paper Forms vs. Automated Custody Tracking

A spreadsheet or PDF form works for a single device or a small matter. It does not scale to modern data volumes or to ephemeral sources like Slack and Microsoft Teams, where custody is nearly impossible to track by hand. Manual logs also depend on people remembering to update them, the exact failure point that breaks chains.

Modern eDiscovery platforms generate the custody record automatically as the work happens, logging every action across the lifecycle. That's the difference between a form someone has to remember to fill in and a record that builds itself. Learn how this fits the broader chain of custody process in eDiscovery.

When Your Chain of Custody Outgrows a Form

A chain of custody form is essential, but it's only as reliable as the person updating it. As matters grow larger, involve multiple custodians, or span modern data sources like Slack and Microsoft Teams, manual logs become difficult to maintain and even harder to defend.

Venio helps legal teams move beyond spreadsheets and PDFs by automatically capturing every collection, transfer, review, and production event in a single auditable workflow. Instead of recreating the chain after the fact, you preserve it automatically from day one. So, contact us today and see how Venio can help you. 

Frequently asked questions

Is a chain of custody form legally required?

There's no single rule mandating a specific form, but you must be able to authenticate evidence under FRE 901, and a complete custody form is the standard way to do it. Under FRE 902(14), a hash-verified record can even let you self-authenticate without live testimony.

What's the difference between a chain of custody form and a chain of custody log?

The form is the overall record for an item; the log is the running list of transfers and accesses within it. In practice, they live in the same document.
