Article 451 Spanish Criminal Code: Accessory After the Fact (Encubrimiento) (2026)

Article 451 of the Spanish Criminal Code (CP) punishes encubrimiento — the closest Spanish equivalent to being an accessory after the fact. It sits in Title XX of the CP among the offences against the Administration of Justice: the accessory is not a participant in someone else's crime, but the perpetrator of a separate, autonomous offence committed after another crime has already been carried out. As criminal defence lawyers for obstruction of justice and concealment offences, we explain what Article 451 actually requires, its three forms, the unusual penalty cap of article 452 and the family exemption of article 454.

What Article 451 Says

The provision imposes 6 months to 3 years of imprisonment on anyone who, knowing that an offence has been committed and without having taken part in it as perpetrator or accomplice, intervenes after its execution in one of the three ways listed by the article. Three common requirements follow from that definition:

1. Knowledge of the prior offence: the accessory must know that a crime has been committed. A vague suspicion is not enough, and there is no negligent version of this offence — it requires intent.
2. No participation in the concealed offence: whoever took part in the main crime as perpetrator or accomplice cannot also be punished as an accessory to their own offence. Covering one's own tracks (autoencubrimiento) is absorbed by the main offence and is not separately punishable.
3. Intervention after the crime: help given before or during the offence is not encubrimiento but participation in the main crime — typically punished far more severely. Where exactly the crime ended is therefore one of the key battlegrounds for the defence.

The Three Forms of the Offence

• 1. Helping the offenders profit (art. 451.1): assisting the perpetrators or accomplices so that they can benefit from the proceeds, product or price of the crime, always without intent to profit personally. Example: keeping stolen money at home so the thief can retrieve it later, taking nothing for yourself. If the helper seeks personal gain, the conduct shifts to receiving stolen goods under art. 298 CP.
• 2. Concealing evidence (art. 451.2): hiding, altering or destroying the body, the effects or the instruments of the crime in order to prevent its discovery. This covers disposing of the weapon, cleaning the scene, wiping digital devices or hiding the stolen items so the offence never comes to light.
• 3. Helping the suspect evade justice (art. 451.3): helping the suspected offenders evade the investigation of the authorities or their agents, or escape their search and capture — the classic scenario of harbouring a fugitive. Unlike the first two forms, however, this one is only a crime in the specific cases described next.

When Harbouring a Fugitive Is Actually a Crime: Art. 451.3

Helping someone dodge the police is not always an offence in Spain. Personal favouring is only punishable in two situations:

• a) Because of the seriousness of the concealed offence: where the concealed crime is treason, homicide of the King or Queen or their ascendants or descendants, genocide, crimes against humanity, crimes against persons and property protected in armed conflict, rebellion, homicide, piracy, human trafficking or illegal organ trafficking, among other offences in the statutory list.
• b) Because of who the accessory is: where the helper acted abusing public functions. In that case — whatever the concealed offence — the prison sentence is supplemented by special disqualification from public office for 2 to 4 years if the concealed offence is less serious, or absolute disqualification for 6 to 12 years if it is serious.

The practical consequence matters: simply hiding a friend wanted for a robbery does not, by itself, fall under art. 451.3, because robbery is not in the statutory list. It is a different matter if that help includes hiding the effects of the crime (form 2) or helping the offender profit from it (form 1), which are punishable whatever the concealed offence.

Penalties and the Cap of Article 452

The standard penalty is 6 months to 3 years of imprisonment. However, article 452 CP adds a proportionality rule that every defence should invoke: the custodial sentence may never exceed the one attached to the concealed offence. The accessory cannot spend more time in prison than the law provides for the main offender.

The same article adds two rules for concealed offences that do not carry prison at all:

• If the concealed offence carries a penalty of a different nature (for example, only a fine), the accessory's prison term is replaced by a fine of 6 to 24 months.
• Unless the concealed offence carries a penalty equal to or lower than that fine, in which case the accessory receives the penalty of that offence in its lower half.

In addition, under article 453 CP the rules on accessories apply even where the perpetrator of the concealed act is not criminally liable or is personally exempt from punishment: the acquittal of the main offender for lack of criminal capacity, for instance, does not drag the accessory's case with it. As for the statute of limitations, with a maximum penalty of 3 years the offence becomes time-barred after 5 years (art. 131.1 CP).

The Family Exemption of Article 454

Spanish law accepts that nobody can be required to hand over their own family. Article 454 CP declares exempt from punishment those who act as accessories for:

• Their spouse or a person linked to them in a stable way by an analogous emotional relationship (a stable partner).
• Their ascendants and descendants.
• Their siblings, by blood or adoption, or in-laws in the same degrees.

The exemption has one single exception: it does not cover accessories under art. 451.1 CP — those who help the relative benefit from the proceeds, product or price of the crime. You may hide your fugitive brother or conceal the evidence against him without punishment; helping him enjoy the loot is a different story. The rationale is that in that scenario the motive is no longer family affection but the consolidation of an unlawful gain.

In practice, this defence is the first box to tick in any accessory case: once the marriage, the stable partnership — which requires stability, not a casual relationship — or the family tie is proven, proceedings against a relative charged under forms 2 or 3 must end without punishment.

Accessory, Receiving Stolen Goods and Money Laundering: Where the Line Runs

Three neighbouring offences share the space of post-crime conduct, and choosing the right classification is decisive:

• Accessory after the fact (art. 451 CP): helping the offenders without intent to profit personally. An offence against the Administration of Justice.
• Receiving stolen goods (art. 298 CP): acting with intent to profit personally from the effects of a crime against property or the socioeconomic order — helping the offenders exploit them, or receiving, acquiring or hiding them. Basic offence: 6 months to 2 years in prison. We cover it in our guide to receiving stolen goods in Spain.
• Money laundering (art. 301 CP): acquiring, converting or transferring assets of criminal origin, or performing acts to conceal their unlawful origin or to help the offender evade the legal consequences of their acts. We analyse it in our post on article 301 CP and money laundering.

The distinction is far from academic: the family exemption of art. 454 CP operates for accessories, but does not exist for receiving stolen goods or money laundering, and neither does the penalty cap of art. 452 CP. Moving the facts from one classification to another can mean the difference between an acquittal and years in prison — in either direction.

Defence Strategies Against an Accessory Charge

1. No knowledge of the prior offence: intent must cover the commission of the concealed crime. Someone who stores a bag without knowing what it contains or where it comes from is not concealing anything.
2. Timing of the intervention: if the help came before or during the crime, the correct charge would be participation, not encubrimiento; conversely, reclassifying an accomplice charge as an accessory charge drastically reduces the penalty.
3. Self-concealment is not punishable: whoever took part in the main offence does not answer separately for covering their own tracks.
4. Art. 451.3 outside the statutory list: in the fugitive-assistance form, checking whether the concealed offence appears in the legal catalogue or whether public functions were abused; if neither applies, the conduct is not an offence.
5. The family exemption (art. 454 CP): proving the marriage, stable partnership or family tie, and that the conduct is not the profit-assistance of art. 451.1.
6. The penalty cap (art. 452 CP): ensuring the sentence never exceeds the penalty of the concealed offence and applying the fine-substitution rules where relevant.

These issues connect with the other offences against the Administration of Justice we cover in our legal guide to obstruction of justice in Spain.
