Criminal law
Published on 17 September 2026
At some point in a Spanish criminal case the defence does a calculation: the likely outcome of a trial, against what is available now without one. That is the conformidad, and it disposes of a large share of Spanish criminal proceedings.
For anyone coming from a common law system it is also the most misread institution in the procedure, because it looks like a plea bargain and does not work like one.
In a conformidad the accused accepts the charge and the sentence sought. The court then gives judgment without hearing evidence.
What it is not: a deal on guilt that the court simply rubber-stamps. The court checks that the facts as accepted actually constitute an offence and that the sentence conforms to law. Nor is it a negotiation with the prosecutor in the American sense: what is negotiated is the charge brought and the sentence requested, not what happened.
And it is not a formality. It is an admission of guilt with everything that follows from one.
A conformidad is subject to conditions that depend on the type of proceedings and on the sentence sought. In fast-track proceedings a conformidad can be entered before the duty court, where the offence carries a sentence of up to three years, and the requested sentence, reduced by one third, does not exceed two years of imprisonment (article 801 of the Criminal Procedure Act).
These rules have changed recently, which is why older accounts should be read with care: article 787, which governs how the court checks a conformidad, was given a new wording by Organic Act 1/2025, in force since 3 April 2025.
What matters in practice is that there is a right moment. Enter too early and you give up knowledge the file has not yet yielded. Too late, and the advantage that made it attractive has gone.
The trial, and with it everything that happens at one: witnesses are not questioned, expert evidence is not tested, contradictions in the file are never exposed. Cases are also won because evidence delivers less in court than it promised on paper.
And, as a rule, the right to appeal a judgment you agreed to.
So the question before a conformidad is never simply whether the sentence offered is low. It is how well the allegation would hold up if it were tested.
This is where foreign clients lose most, and it is not on the sentence length.
A conformidad produces a conviction, and a conviction produces a criminal record. For a foreign national that record can affect the renewal of a residence permit or an application for nationality, years later.
The detail worth knowing, because it cuts the other way: when a residence permit is renewed, the law expressly requires the authorities to weigh the record "taking into account any pardons, or situations of conditional remission of the sentence or suspension of a custodial sentence" (article 31.7 of Organic Act 4/2000). A suspended sentence is not treated as if it had been served. That does not make the record harmless, but it is a factor the administration is obliged to consider, and it is worth having on the file rather than assuming the worst. What a record means for your residence permit therefore belongs in this calculation.
Then there are the ancillary consequences that get overlooked: disqualification from a profession, driving bans, compensation orders, and in business cases the question of what an admission means for the company, which may well be under investigation alongside you.
When the case rests on a single piece of evidence that would not survive questioning. When the file contains a contradiction that only a trial would surface. When the ancillary consequences outweigh the sentence, which with residence and profession is often the case. And always when it is proposed before anyone has read the complete file.
I work out both sides before recommending anything: the likely outcome of a trial, and the full consequences of the conformidad rather than just the sentence. Those consequences expressly include what the record would mean for your residence, because with foreign clients that is frequently the more expensive item.
Then I tell you what I think is right and why, with the figures it rests on. The decision is yours, and you should make it having understood what you are giving up. You can read how I work, or what I do in criminal defence in Barcelona.
