If a relative has just been remanded in custody in Spain, waiting for a trial that may be months away, it is one of the hardest moments of a criminal case, especially in serious matters like drug offences. Pre-trial detention in Spain is not a sentence, and it is not automatic. Understanding what it requires, how long it can last and what room there is to fight it helps you face the hearing with a clearer head.
What is pre-trial detention in Spain?
Pre-trial detention (prisión provisional) is a precautionary measure, not a punishment. It means the person is held in prison before there is any judgment, while the case is investigated or awaits trial. Because it affects the liberty of someone who is still presumed innocent, the law treats it as exceptional and surrounds it with strict requirements.
What does the law require? (Article 503 LECrim)
Under Article 503 of the Spanish Criminal Procedure Act (LECrim), several conditions must all be met: the offence under investigation must carry a sentence above a minimum threshold, there must be sufficient evidence that the person took part, and the measure must pursue a legitimate aim. Those aims are limited: preventing a risk of flight, stopping evidence being destroyed or hidden, avoiding repeat offending, or protecting the victim. Without one of those aims, pre-trial detention cannot be ordered.
How long can pre-trial detention last?
It is not indefinite. The law sets maximum periods according to the seriousness of the penalty, and within those limits the detention must last only as long as strictly necessary:
- Offences punishable by up to 3 years: an initial maximum of 1 year, extendable by a further 6 months.
- Offences punishable by more than 3 years: an initial maximum of 2 years, extendable by up to 2 more years.
When the limit approaches, or when the circumstances that justified it change, release or a less restrictive measure can be requested.
How to fight it: the alternatives
Pre-trial detention is not the only option. The judge can order less restrictive measures that serve the same aim: bail, an obligation to report to court periodically, surrender of the passport, a ban on leaving the country, or frequent check-ins. The defence works to show those alternatives are enough and that there is no real risk of flight, of evidence being destroyed or of repeat offending. Being a foreign national, on its own, does not make detention inevitable, but it does make it essential to document ties to Spain and to argue each point properly.
If the arrest has just happened, it helps to know what happens in the first 72 hours, because that is where the defence starts.
The Article 505 hearing: the moment that decides it
The decision is taken at a hearing (under Article 505), attended by the judge, the prosecutor and your lawyer. It is decisive and it plays out in very little time: that is where it is argued whether remand or an alternative applies. Arriving well prepared, with documentation of ties to Spain and arguments against each aim the prosecution relies on, can be the difference between going into prison and awaiting trial in freedom. If your relative is in this situation and you need a lawyer who can act in English from the first moment, tell me about the case as soon as possible.
