Timestamping for law firms: the short answer

Timestamping for law firms means recording a fingerprint of a file at a moment that matters: when a client hands over their work, when a draft goes to the other side, or when advice is sent. Recording that fingerprint on the Bitcoin blockchain shows that the exact file existed no later than the recorded time, and that a copy shown later still matches its fingerprint. With TimeBinder, files are fingerprinted on your own computer and never uploaded, so client documents stay inside the firm. A TimeBind doesn’t show who created a file, whether its contents are true, or how a court or registry will treat it. Those questions stay with you as the lawyer.

This is general information, not legal advice. Questions about your own professional obligations, such as confidentiality, file retention, the use of technology in practice and how you describe a service to clients, are for you and your law society or regulator.

What is TimeBinder? TimeBinder is a blockchain timestamping service. It shows that a digital file existed no later than a specific time, and that it still matches its fingerprint, by anchoring the file’s SHA-256 fingerprint to the Bitcoin blockchain. Files are hashed in your browser and never uploaded, and each TimeBind comes with a Proof of Time Certificate that can be checked later. It does not prove who created a file or that its contents are true.

Why timestamping matters in a law practice

IP clients often arrive with a version of “we had this first”. A timestamp can’t look backwards, but from the day a client instructs you it can record exactly which files they held, so there’s no later question about what was in the bundle.

In commercial work, questions tend to be about versions: which draft the other side saw, or what the advice said when it went out. Your document management system records dates on your own systems. A TimeBind adds a date for the exact file that sits outside them.

Because nothing is uploaded, you can do this without sending client documents to another provider.

What IP and commercial lawyers timestamp

  • Client materials at intake for IP matters: drafts, designs, source code, manuscripts or recordings the client hands over. This records what the client held on that date, not who made it.
  • Each contract draft as it goes to the other side, and the executed version.
  • Advice letters and file notes as they’re sent or finalised.
  • Brand and design materials before a trade mark or design application is filed.
  • Confidential information packs handed over under a non-disclosure agreement.
  • Document sets as served, as one zip or a list of file fingerprints.

Each TimeBind holds up to 10 files. Zip a larger set and timestamp the zip.

A routine for client files

  1. Finalise the exact file. Export the PDF as sent, or zip the client’s bundle as received. Don’t re-save it afterwards, because the TimeBind matches the exact file.
  2. Make the TimeBind in the TimeBinder app.
  3. Keep reference text generic. Reference text you add is processed by TimeBinder, so use a matter number rather than client names.
  4. File the certificate with the matter, alongside the original file.
  5. Choose who can check it: public by QR code, or restricted to email addresses you choose, such as the client’s.

How firms can date a document

These tools do different jobs, and most firms will keep using all of them. For more, see blockchain timestamp vs notary and RFC 3161 vs blockchain timestamps.

What a TimeBind shows, and what it doesn’t

What it shows

  • That this exact file existed no later than the time recorded on the Bitcoin blockchain
  • That a file shown later still matches its fingerprint: the same file gives the same fingerprint, and any edit gives a different one
  • A record kept outside your own systems: an ASAP TimeBind can be checked on the Bitcoin blockchain without relying on TimeBinder, and a Pooled TimeBind is verified through TimeBinder

What it doesn’t show

  • Who created, wrote or signed the file, or who owns it
  • That the contents are true or accurate
  • That the file existed any earlier than the recorded time
  • How a court, tribunal or registry will treat it. That depends on the jurisdiction and the rules that apply, and it isn’t legal advice

Pooled TimeBinds are verified through TimeBinder; ASAP TimeBinds can be verified independently from the certificate and the Bitcoin blockchain. Checking a TimeBind is always free.

Which plan suits a law firm

A sole practitioner timestamping a few matters a month may only need Expert, at USD $50 a month for 15 Tokens, or the Free plan plus Tokens when needed. A firm timestamping several matters a week is usually better on Business: USD $149 a month for 60 Tokens, one company account, a monthly invoice and help getting set up. Business Plus is USD $299 a month for 150 Tokens. If your IT provider wants to timestamp from your own systems, API access is included in the Business, Business Plus and Enterprise plans. See TimeBinder business plans for the details, and the legal document verification guide for more on legal documents.

When another option suits better

  • Your client needs a registered right, such as a trade mark, design or patent. That comes from filing with IP Australia or the office in the relevant country. A timestamp doesn’t register anything. See copyright registration vs a timestamp.
  • You need signatures or witnessing. Use e-signature, a notary or a justice of the peace, as the matter requires.
  • You need a records system. TimeBinder doesn’t store files, so your document management system stays the record.
  • The question is about an earlier date. A TimeBind made today shows what a file looks like today, not last year.

Timestamping for law firms: FAQ

Is TimeBinder legal advice?

No. TimeBinder records when a file existed. It doesn’t give legal advice, and how you use a TimeBind in a matter is your professional judgment.

Does a timestamp show who created a client’s work?

No. A TimeBind shows that the exact file existed no later than the recorded time, and that a copy still matches its fingerprint. It doesn’t show who created the file or that its contents are true.

How will a court treat a TimeBind?

We can’t say. That depends on the jurisdiction, the matter and the rules that apply, and it’s a question for you as the lawyer. TimeBinder doesn’t give legal advice or confirm how evidence will be treated.

Are client files uploaded to TimeBinder?

No. Each file is fingerprinted on your own computer and never leaves it. Only the fingerprint, and any reference text you add, is processed by TimeBinder, so use a matter number rather than client names in reference text.

Can we limit who checks a certificate?

Yes. Verification can be public, by QR code, or restricted to email addresses you choose, such as the client’s.

Yes. Business is USD $149 a month for 60 Tokens with a monthly invoice. Business Plus is USD $299 a month for 150 Tokens. API access is included in the Business, Business Plus and Enterprise plans. A sole practitioner may only need Expert, at $50 a month for 15 Tokens.
