Explanation and defense

What Article 399 of the Criminal Code punishes

Article 399 punishes the forgery of certifications by a private individual, among the offences of forgery. It applies to anyone who, without being an authority or public official, forges one of the certifications referred to in the preceding articles of the chapter, as well as to anyone who knowingly uses that false certification or, without having taken part in the forgery, trades in it in any way. The provision applies even where the certificate appears to belong to another EU Member State or a third State, or was forged or obtained outside Spain, if it is used within Spanish territory.

Penalty

The penalty is a fine of three to six months, both for whoever forges the certification and for whoever knowingly uses or trades in it. It is therefore a less serious offence within the forgery offences, the legislator reserving prison sentences for the forgery of public, official or commercial documents and for certifications issued by an authority or official.

Defense strategy

The defense should verify that the disputed document genuinely falls within the "certification" category the offence requires, rather than that of an official or public document, whose forgery carries much heavier penalties under the preceding articles. The subjective element of knowledge is equally essential: someone who uses a certification without knowing it is false does not commit the offence, since the provision requires acting "knowingly".
