Colombian Court Accepts WhatsApp Chats as Labor Dispute Evidence

Colombia’s Supreme Court has ruled that printed WhatsApp screenshots can be considered documentary evidence in labor disputes. The decision, issued by the Labor Cassation Chamber in 2026, clarifies their legal status under Article 243 of the General Code of Procedure.

The ruling states that WhatsApp conversations are documentary evidence even without a signature, provided the opposing party does not dispute their authenticity. However, the court emphasized that such evidence is not automatically conclusive. The content must demonstrate a genuine agreement or consent to be considered valid proof.

For instance, they noted that a screenshot of an employee requesting transportation without a response or approval from their supervisor does not prove authorization. If the other party objects, the evidence’s effectiveness diminishes, requiring more rigorous digital traceability for complex messages.

For a judge to accept a WhatsApp conversation as evidence, it must meet specific technical and legal criteria. The sender and recipient must be clearly identified, linking their phone numbers or devices directly to the involved parties. The content must be unaltered, unedited, and presented in its entirety to preserve the conversation’s context.

The court recommends avoiding isolated screenshots, as they can be easily challenged due to the simplicity of fabrication or editing. Instead, providing a complete chat history and obtaining expert testimony from a computer forensics specialist is advisable.

A forensic expert can extract and analyze metadata or the original device’s hash code to verify the messages’ authenticity, integrity, and authorship. Specialized software can extract data while maintaining the chain of custody.

To strengthen the evidentiary value of WhatsApp chats, the court suggests involving a public notary to certify the content directly from the device before messages can be deleted. Preserving the original device and avoiding alterations or edits to the messages are also critical steps in ensuring admissibility.
