Your employer disputes the date of an HR document — what to do?

An HR document without proof of date is an open door to disputes

You submitted a resignation letter, signed a severance agreement, received a warning, or sent sick leave documentation. Some time later, your employer or former employer disputes the date of this document, claims to never have received it, or says the timeline of events was different. In an employment tribunal context, the burden of proof is heavy and the financial stakes are significant. A simple email or paper copy can be challenged. Without independent technical proof, you're in a weak position.

Responding to an HR dispute: your concrete options

• Immediately gather all existing documents: emails, receipts, text messages, written colleague testimonies.
• Keep a copy of every disputed document in a secure location outside the company.
• Contact an employee advisor or employment law attorney before any formal response.
• If the dispute is active, file with the Employment Tribunal if necessary.
• Never sign a document under pressure without time to reflect.

ProofStamper cannot resolve an ongoing dispute — it protects for the future. For an active HR dispute, consult an employment law attorney or employee advisor.

An email or paper copy can be challenged at the Employment Tribunal

In an employment tribunal dispute, the opposing party will systematically challenge any evidence whose date can be questioned. An email can be backdated, a paper copy can be recreated, a postal receipt can be lost. Only a timestamp from an independent trusted third-party authority, using the RFC 3161 standard, produces proof whose date is technically indisputable and verifiable by any judicial expert.

Next time, timestamp every sensitive document before sending

I'm finalizing an important HR document before handing it over or sending it.

I generate a timestamped proof of the document in 30 seconds.

I can prove this document existed at this exact date, before any sending or handover.

The file never leaves my device. Only the SHA-256 fingerprint is transmitted.

Certify every sensitive document in your professional life

• Resignation letter
• Severance agreement
• Warning received
• Sick leave
• Interview report
• Leave or remote work request

Which proof of date to choose for an HR document?

Four approaches compared.

3 steps before each document handover

1. Drop your finalized document: Resignation letter, severance agreement, warning, sick leave… any format.
2. Automatic local certification: SHA-256 hash computed in browser + RFC 3161 timestamp via FreeTSA.
3. Download your Proof Pack: PDF certificate + .tsr token. Archive it with your original document.

Frequently asked questions

Is this proof admissible at the Employment Tribunal?

The RFC 3161 certificate constitutes technical proof of priority. Combined with a sworn statement, it represents a solid element for establishing a document's existence date in an employment dispute.

Is my document sent to your servers?

No, never. All processing happens locally in your browser. Only the cryptographic fingerprint (SHA-256) — a unique identifier that cannot reconstruct your document — is transmitted for timestamping.

Can I timestamp an already signed document?

Yes. You can timestamp any file, including a document already signed by hand or electronically. The timestamp proves this exact version existed at this date.

What if my employer refuses to acknowledge the proof?

The RFC 3161 certificate is issued by an independent trusted third-party authority. Its validity is verifiable by any judicial expert. In case of challenge, a specialized lawyer can use it as complementary evidence.

Does this proof replace registered mail?

No. The timestamp proves a document existed at a given date, not that it was sent or received. To prove receipt, registered mail is still necessary. Both are complementary.
