What does CustodyTrack actually store?

Hash values and minimal metadata — never the contents of your evidence, and never the full text of your form. That is what makes a record safe to hand to an opposing party: they can confirm it is unaltered without learning what it describes.

What does a successful verification prove?

That the form and its custody history are exactly what was sealed, and that no entry has been altered, inserted, or removed since. It is evidence about the record, not about the truth of what someone wrote into it — a distinction worth keeping straight in testimony.

Can I add my own fields to a form?

Yes. Every template accepts custom fields, and you can start from a blank form instead. The supplied templates are informed by NIST SP 800-86, ISO/IEC 27037, and SWGDE practice documents rather than invented, so the fields read the way an examiner expects them to.

What happens if a record is altered after it is sealed?

Verification fails, and it fails at a specific entry — each event carries the digest of the event before it, so a change anywhere breaks every seal that follows. The record is tamper-evident: alteration is detectable, not prevented, and being able to state that distinction precisely is what survives cross-examination.

Can I produce a form for an exhibit binder?

Yes. A form exports as a PDF carrying its verification code, so the copy in the binder points back at a check anyone in the room can run for themselves without an account.

Everything you need to prove custody.

CustodyTrack turns chain of custody into a tamper-evident, verifiable record — from the moment evidence is collected to every transfer that follows.

Authenticate

Customizable chain of custody forms

Build Authenticated Chain of Custody Forms for a wide variety of use cases — physical or digital evidence, from a single item to a full intake. Add your own custom fields when a matter needs them. To protect privacy, our approach stores only hash values and minimal metadata, never the full contents of your form.

Build a form free — no account needed →

A verifiable 3-step transfer workflow

Transfer custody to anyone — even someone without an account. The recipient receives a secure link, confirms their identity, and signs to accept. Both parties acknowledge the handoff, and a tamper-evident, cryptographically verifiable record of the transfer is sealed into the form's history.

Free verification, without exposing evidence

Any third party can confirm that a form and its custody history are authentic and unaltered — using only a verification code. Because we store hash values rather than contents, verification never requires you to share the underlying evidence information.

Independent, end-to-end auditing

Beyond a single form, anyone can validate the consistency and integrity of the entire record set: every custody event is sealed into one global ledger, so an entry cannot be altered, inserted, or removed without breaking every seal after it. The ledger re-computes on demand, so oversight doesn't depend on trusting us — it depends on the math.

Built for how evidence is actually collected.

Start from a scenario template — each one guides you through the fields that matter for that kind of evidence, following SWGDE, NIST SP 800-86, and ISO/IEC 27037 practice. Or start blank and build your own.

Who it's for

The same record, four different jobs.

What a property and evidence unit needs from a custody record is not what a solo litigator needs from one. Each page below covers the workflow, vocabulary, and templates for that work.
