Es lo que manifiesta la modificación del artículo 299.2 de la Ley de Enjuiciamiento Civil, que incorpora la prueba documental electrónica a los procedimientos judiciales. Aquí, encaja perfectamente el email certificado.
Esta validez legal viene especificada en el Reglamento eIDAS, que aplica en el territorio de la UE y, por tanto, en España. El resto de países tienen normativas similares.
Sin embargo, conviene destacar que, para que tengan valor probatorio total, es imprescindible que estos correos garanticen su integridad y su inalterabilidad, a la vez que se puede contrastar su fecha y hora de envío. También es imprescindible que se respeten, en todo momento, las normativas sobre protección de datos en lo referido al email certificado, su integridad y confidencialidad.
