Electronic certificates for minors
The electronic certificate, such as the one issued by the FNMT , may only be requested by an adult or an emancipated minor. It should be remembered that Spaniards come of age at 18 years of age. Foreigners must prove their age of majority, depending on their country of origin, by means of a certificate from their embassy or consulate.
As for emancipated minors, to request an electronic certificate, they will have to prove their emancipation by means of a literal certificate from the Civil Registry. If the minor is an emancipated foreigner, he/she must prove this circumstance with the corresponding certificate from his/her embassy or consulate.
In relation to card certificates such as the electronic signature of the electronic DNI , it should be noted that according to article 1.4 of Royal Decree 1553/2005, of December 23, which regulates the issuance of the national identity document and its electronic signature certificates, it only allows Spanish adults with full legal capacity to electronically identify its holder as well as to electronically sign their documents. In the case of Spanish minors, or those who do not have full legal capacity, it establishes that the electronic DNI will only contain the utility of electronic identification, for which it will be issued with the respective authentication certificate activated.
Therefore, with the electronic DNI the minor will be able to prove his/her identity by electronic means but will not be able to make an electronic signature.
