Document forgery: criminal defence

Criminal defence throughout Spain · offices in Madrid and Alicante

False invoices, altered contracts, certificates, scanned signatures and manipulated digital files. Document forgery accompanies almost all economic crime, and it is won or lost through handwriting and digital forensic examination.

In brief. Document forgery is, by definition, an offence proved by expert evidence. Whoever controls the forensic examination controls the case. The decisive questions are what counts as a commercial document, when a falsehood is a mere ideological untruth that is not punishable for a private individual, and whether the document is capable of altering legal transactions.

Our own methodology of legal intelligence and forensic analysis.

Document forgery admits no analysis without expert examination

Proceedings for forgery share a single requirement: to examine every document technically. Handwriting, inks, media, file metadata, digitised signatures and edited PDFs; modern forgery is at once physical and electronic.

To this is added a fine point of law: what constitutes a commercial document, when a falsehood is merely ideological and not punishable for a private individual, and when a document is capable of altering legal transactions. That dual plane, technical and legal, is where these cases are decided. For that reason we bring together criminal defence and a documentary and digital forensic laboratory within a single team.

Types of offence

The framework of Articles 390 to 400 bis of the Criminal Code

Forgery by a private individual of a public, official or commercial document: the most frequent offence in the economic sphere. Penalty: six months to three years, and a fine.

Our differentiator

Where forgery meets forensic analysis

The evidence in a forgery is, by definition, expert evidence: handwriting, inks and media on the physical side; metadata, hashes and editing traces on the digital side. Whoever controls the forensic examination controls the case. For that reason we apply LIWARD, Legal Intelligence Warfare for Defense, our own methodology, which integrates legal intelligence, case-law analytics, financial and accounting analysis and e-forensics into a single procedural strategy. That is what distinguishes us from conventional criminal defence.

FAQ

Frequently asked questions

A contract with my signature forged on it has been produced against me. What do I do?
Do not acknowledge the document and immediately request a handwriting examination of the original. Demanding production of the original is key: copies hinder the expert examination, and their absence weakens the party producing the document. We coordinate the criminal route with the civil matter affected.
Is a false invoice always a serious offence?
An invoice is a commercial document: its forgery falls under Article 392 (six months to three years). If it also served to defraud the tax authorities or to commit fraud, the medial concurrence increases the penalty. The defence contests the material falsehood that is relevant and both material and intellectual authorship.
What is ideological forgery and when is it not punishable?
Departing from the truth in the narration of facts is not punishable for a private individual (Article 392 excludes Article 390.1.4º): stating false data in a genuine document is not always criminal forgery. This technical distinction leads to the dismissal of many ill-founded complaints.
Can manipulation of digital documents (PDF, Word) be detected?
Yes: the forensic analysis of metadata, versions, layers and editing traces makes it possible to establish manipulations, the real dates of creation and inserted signatures. Our laboratory issues reports that withstand challenge at trial.
Do you handle cases outside Alicante?
Yes. We operate from Madrid and Alicante and provide assistance anywhere in Spain, including urgent assistance to detainees and proceedings with an international dimension.
What is the LIWARD methodology?
It is our own methodology, Legal Intelligence Warfare for Defense, which integrates legal intelligence, case-law analytics, financial and accounting analysis and e-forensics into a single procedural strategy.
