Digitally Signed Employment Contracts: Validity, Retention and Long-Term Evidence

Electronic employment contracts can make hiring faster and easier, but the legal and evidential questions do not end when the signature is applied. HR teams must know whether the signing method is accepted, how the contract must be stored, how the employee can access it and whether the evidence will remain reliable after certificates or systems change.

This article focuses on Belgian employment contracts and the long-term evidence around them. It is general information, not legal advice for a specific case.

Can an employment contract be signed electronically in Belgium?

Yes. The Belgian Federal Public Service Employment states that an employment contract signed with the electronic signature created by the Belgian electronic identity card is equivalent to a paper contract signed by hand.

The official guidance also recognises a Qualified Electronic Signature within the meaning of eIDAS as equivalent. This does not mean that every other electronic signing method is automatically equivalent. The employer and employee must agree to use the electronic form, and neither party can be forced to conclude the employment contract electronically.

The practical lesson is that HR should not treat every click, scanned signature or signing platform as legally equivalent. The signing method, identity assurance and applicable employment rules must be checked for the specific process.

What must happen after signing?

The Federal Public Service Employment states that a copy of the electronically concluded employment contract must be stored with a provider of an electronic archiving service.

The employee must be able to access the archived copy. The employer must also explain the electronic archiving service and access method in the work regulations, and the storage arrangement must support the legally required availability period.

The official rules should be checked whenever the process is designed or changed. Relevant starting points include Articles 3bis and 3ter of the Belgian Employment Contracts Act and the Federal Public Service Employment guidance on electronic employment contracts and documents.

Validity at signing is not enough

The evidentiary value of a digital contract depends on more than the visible signature. Years later, an organisation may need to prove:

• which document the parties signed;
• who signed it and under which signing method;
• whether the file changed after signing;
• whether the certificate was valid and not revoked at the relevant time;
• when the signature was applied;
• how the document was stored, accessed and governed;
• which retention rule applied.

A PDF stored in an HR platform or shared folder may remain readable without retaining all this evidence. That distinction becomes important during a dispute, inspection or system migration.

Preserve the document and the signature evidence

Electronic signatures depend on certificates, timestamps, revocation information, algorithms and trust chains. Those dependencies change or disappear over time.

A sound archiving process validates the signed document while the required evidence is available and preserves the document with its validation context. Long-term preservation can renew evidence before certificates or algorithms become unreliable, while maintaining the relationship with the original signed file.

For HR, this means preserving:

• the exact signed contract;
• signature and certificate information;
• timestamps and available revocation evidence;
• validation results;
• employee and contract metadata;
• provenance and audit events;
• retention, access and legal-hold context.

Access, retention and controlled disposal

Employment records do not all have the same retention period. The applicable period depends on the document type, legal basis and employment context.

The archive should therefore apply a documented retention category rather than a generic rule for the entire personnel file. It should also support:

• authorised access for HR and other defined roles;
• employee access where the law requires it;
• legal hold when deletion must be suspended;
• traceable changes to retention decisions;
• controlled and evidenced disposal at the end of the retention period.

Retention must be based on current legal and organisational policy. The archive enforces the approved rule, but does not decide the legal period by itself.

Common mistakes

Treating every electronic signature as equivalent

The legal effect and evidential strength depend on the signing method and the applicable rules. HR should verify the required signature level instead of assuming that any electronic signing workflow is sufficient.

Keeping only a downloaded PDF

The PDF may not contain all the validation, revocation, timestamp and process evidence required later.

Leaving contracts in the signing or HR platform indefinitely

Operational systems change. They may not be designed to preserve records and cryptographic evidence throughout the required retention period.

Applying one retention period to the entire personnel dossier

Contracts, payroll records, identity data and other HR documents may have different legal bases and retention periods.

Assuming that a vendor’s marketing claim proves qualification

Qualification status and scope should be checked against the applicable Trust List or official national evidence.

A practical HR checklist

1. Confirm that both parties agree to the electronic process.
2. Verify the legally accepted signing method for the contract type.
3. Preserve the exact signed document and its validation evidence.
4. Record provenance, timestamps, certificate and revocation information.
5. Define how the employee will access the archived contract.
6. Document the archiving provider and access method in the required HR policies.
7. Apply the correct retention category and legal-hold process.
8. Test retrieval and validation after migration or platform change.
9. Verify the provider’s current qualification status and scope where a qualified service is required.
