Key takeaways
- Digitising HR documents is not sufficient to guarantee their legal validity.
- Evidential weight depends on three conditions: an appropriate electronic signature, qualified timestamping and evidential electronic archiving.
- Certain HR acts (dismissal, contractual amendments, formal notices) require a legally reliable and enforceable date.
- The GDPR and employment law impose specific retention periods, including for digital documents.
- A qualified trust service provider ensures the enforceability of the document over time.
What is HR digitisation?
Digitisation in the field of human resources covers two distinct realities that should not be confused.
The first concerns the digitisation of documents:
- payslips,
- employment contracts,
- contractual amendments,
- certificates,
- termination documents.
These documents now exist in digital form, either because they were originally created electronically or because they were digitised retrospectively from a paper original.
This distinction is significant. Simple scanning does not create an original digital document. It merely produces a copy whose evidential value remains dependent on precise technical conditions.
The second concerns the digitisation of HR processes:
- remote contract execution,
- automated transmission of payslips,
- approval workflows,
- electronic management of employee records.
These processes generate genuine operational efficiencies. However, they also raise a question that too few organisations anticipate: at what stage in this digital chain is the legal validity of the document actually secured?
Which documents and processes should be digitised as a priority?
HR digitisation covers the entire employee lifecycle, from recruitment to termination of employment.
Certain documents are subject to specific legal obligations.
Electronic payslips
Electronic payslips have been regulated since the French Labour Law reform of 2016 (Article L.3243-2 of the French Labour Code): employers may issue payslips electronically without the employee’s prior consent, provided that the integrity of the document is guaranteed and its availability ensured for five years.
Personnel files
Personnel files must be retained for the duration of the contractual relationship, together with the applicable limitation periods (up to fifty years for certain pension-related documents).
Other HR acts demanding vigilance
Other HR acts require particular care. A unilateral amendment to an employment contract, a dismissal notification, a formal notice or an invitation to a preliminary meeting are all acts with direct legal consequences. A simple email or exported PDF without additional safeguards does not reliably establish the date of dispatch, the identity of the sender or the absence of subsequent alteration. These are precisely the deficiencies that employment tribunals may sanction.
The electronic registered letter illustrates this requirement clearly. When used in the situations described above, it only produces legal effect if the date of dispatch and the identity of the sender are established in a certain and enforceable manner. Qualified timestamping within the meaning of the eIDAS Regulation satisfies this requirement, whereas a standard email or conventional messaging platform does not. This is the case with Postclic, whose electronic registered letter solution relies on Evidency’s qualified timestamping service to guarantee the evidential value of each dispatch.
The GDPR also applies to all personal data contained in HR documents. It imposes defined retention periods, regulated access rights and data security obligations, including for digital records.
What are the advantages of HR digitisation?
Digitisation in human resources generates concrete benefits on two levels: operational first, legal second. It is this second dimension that distinguishes properly implemented digitisation from the mere conversion of paper workflows into digital form.
Operational benefits
According to the 2024 HR Barometer published by Éditions Tissot, 94% of HR professionals support the digitisation of administrative documents. Among them, 91% identify time savings and improved efficiency as the principal advantage.
Other operational benefits include:
- reduced processing times,
- removal of printing and delivery costs,
- remote access to files,
- traceability of document workflows.
These gains are genuine and often constitute the primary driver behind digitisation projects. However, properly implemented digitisation provides an additional advantage that is less frequently highlighted: it creates a mechanism for the preconstitution of evidence.
Legal and evidential benefits
An HR document created natively in digital form, qualified timestamped, sealed with an electronic seal and retained within an evidential electronic archiving system offers safeguards before a court that paper documents do not always provide.
What must be demonstrated is not merely the existence of the document, but also its origin (who issued it), its integrity (that it has not been altered since creation) and its traceability (the date and conditions under which it was produced).
A properly secured HR document satisfies all three requirements. A document that has merely been digitised does not.
HR digitisation and legal validity: conditions that must not be overlooked
Digitisation alone is not sufficient. For an HR document to be legally enforceable, three conditions must be met.
Electronic signature
The electronic signature must correspond to the level of assurance required by the relevant act. The eIDAS Regulation distinguishes between three levels: simple, advanced and qualified.
A simple electronic signature may be suitable for an acknowledgement of receipt; it is insufficient for an employment contract or termination document where challenge is foreseeable.
The qualified level, which alone has the legal equivalence of a handwritten signature, guarantees both the identity of the signatory and the integrity of the document.
Qualified timestamping
Qualified timestamping attaches a reliable, verifiable and tamper-proof date and time to the document, recognised throughout the European Union under the eIDAS Regulation. Without qualified timestamping, the date of a digital document may be challenged. This considerably weakens its evidential value in litigation.
Qualified electronic archiving
Evidential electronic archiving guarantees the integrity of the document over time. Retaining a file on a server or within an HRIS does not constitute legally secure archiving.
An electronic archiving system compliant with NF Z42-013 and eIDAS standards ensures that the document cannot be altered after deposit and that its integrity remains verifiable at any time. This is the role of the qualified trust service provider, whose intervention guarantees the enforceability of the document against third parties, including in employment disputes or administrative inspections.
Solutions such as Evidency make it possible to combine these three levels of protection (qualified timestamping, electronic sealing and evidential electronic archiving) within a single workflow, without complicating existing HR processes.
What should you consider before launching your HR digitisation project?
Digitisation in human resources is first and foremost a management decision. It generates measurable productivity gains and simplifies the day-to-day work of HR teams. However, its true value becomes apparent when a document is challenged: when an employee denies receipt of a notification, when a labour inspector requests verification of a contractual amendment or when a judge questions the legally reliable date of an act.
The question to address before launching any project is therefore not simply “how do we digitise our documents?” but rather “under what conditions will these documents be legally enforceable?” Anticipating this issue means transforming a productivity project into a documentary trust infrastructure and ensuring the organisation is prepared to respond to disputes before they arise.
