Irish law on false documents: forgery, use, possession and deception

Short answer: The Criminal Justice (Theft and Fraud Offences) Act 2001 makes forgery, using a false instrument and having one in your control offences, with ceilings of 10 years for forgery and use and 5 years for simple possession. Gaining by deception carries up to 5 years. These are maximums on indictment, not typical sentences.

What "false" means

Section 30 treats an instrument as false if it purports to have been made, in its form or terms, by someone who did not make it, or on the authority of someone who did not authorise it; if it purports to have been altered by someone who did not alter it, or without authority; if it purports to have been made or altered on a date or at a place when it was not; or if it purports to have been made by a person who did not exist. A person who alters an instrument so as to make it false in any respect is treated as having made a false instrument.

Prejudice and machines

Under section 31, an act induced is to a person's prejudice if it would cause loss of property, deprive them of an opportunity to earn or gain, or give another that opportunity, or if the person accepts a false instrument as genuine in connection with performing a duty. Inducing a machine to respond to a false instrument as if it were genuine is covered too. That wording is why impersonating a candidate on a computer-based test was charged as conspiracy involving unlawful use of a computer and deception.

Driving without a licence

Section 38 of the Road Traffic Act 1961 prohibits driving a mechanically propelled vehicle in a public place unless you hold a driving licence for the time being having effect and licensing you to drive it. Owners may not employ someone to drive who does not hold such a licence. The Act we read is the version as enacted, whose penalties were expressed in pounds and have since been amended, so we do not state a current penalty.

What the reported cases show

The outcomes we found sit far below the ceilings: a €500 fine under section 26 in Tallaght, two €750 fines in Roscommon, a two-year driving ban with €500 in fines in Dublin, and short or suspended prison terms in the theory test cases. The case log lists them with sources. A ceiling is a ceiling, not an expectation.

Summary cases

The ceilings above apply on conviction on indictment. Many of the reported licence cases were heard in the District Court, where we have not read the summary limits, and we state none.

How the reported cases map to the Act

Reported caseCharge as reported
Tallaght, November 2025Using a false driving licence, contrary to section 26
Letterkenny, October 2024Possession of a fraudulent theory test certificate with intent to induce acceptance as genuine (the report does not name the section)
Dublin, 2025 to 2026Conspiracy, with unlawful use of a computer and deception; the 2025 charge was reported under section 71 of the Criminal Justice Act 2006, which we have not read
Roscommon, December 2024 offencePossession and use of a forged licence

Why ceilings are not predictions

A ceiling is the most a court may impose. Judges weigh the facts, any guilty plea, previous convictions and personal circumstances. In the Tallaght case the report records that the defendant admitted the licence was false and had eight earlier convictions. The sentence was a €500 fine. We list ceilings so readers understand that these are serious offences, not to suggest that any case will end that way.
