Criminal law
Published on September 17th, 2026
For a foreign client, the number of months in a conformidad is rarely the expensive part. The accused accepts the charge and the sentence sought, the court gives judgment without hearing any evidence, and the consequences surface years later, when a residence permit comes up for renewal or an application for nationality is filed.
It disposes of a large share of Spanish criminal proceedings, and it is very often the sensible choice. The English-speaking shorthand for it is plea bargain, which is close enough to be useful and misleading in the places that matter on the day.
Before it can give judgment, the court checks that the facts as accepted actually constitute an offense and that the sentence conforms to law, so it does not simply rubber-stamp the deal. What gets negotiated is the charge brought and the sentence requested, and what happened stays where it is. A conformidad is also an admission of guilt, with everything that follows from one, however quickly the procedure ends.
A conformidad produces a conviction, a conviction produces an entry in the criminal record, and that entry can touch the renewal of a residence permit or an application for nationality years later, when the case itself is long closed. This is where foreign clients lose most, beyond the number of months.
In the other direction, 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 therefore not treated as though it had been served, which does not make the record harmless but makes it something the administration must consider. What a record means for your residence permit belongs in the same calculation as the sentence.
Ancillary consequences are easy to overlook: disqualification from a profession, driving bans, compensation orders and, in business cases, what an admission means for the company, which may well be under investigation too.
Whoever agrees waives the trial and everything that happens in it, so witnesses are not questioned, expert evidence is not discussed and the contradictions in the file are not brought out, and cases are also won because evidence delivers less in court than it promised on paper. The waiver of appeal is the quieter one, since a judgment you agreed to generally cannot be appealed.
The question is how well the allegation would hold up at trial, and only after that whether the sentence on offer is low.
How a conformidad works depends on the type of proceedings and on the sentence sought. In fast-track proceedings it can be entered before the duty court if the offense 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). Article 787, which governs how the court checks a conformidad, was given a new wording by Organic Act 1/2025, in force since April 3rd, 2025, so older accounts should be read with care.
There is also a right moment, since a declaration made too early gives up knowledge the file has not yet yielded, and one made too late has lost the benefit that made it attractive.
I advise against a conformidad when the case rests on a single piece of evidence that would not survive questioning, when the file holds a contradiction that only a trial would surface, when the ancillary consequences outweigh the sentence, which with residence and profession is more common than not, and always when it is proposed before anybody has read the complete file.
Before recommending anything I work out the likely outcome of a trial and the full consequences of the conformidad rather than the sentence alone, and with foreign clients the residence consequence, frequently the more expensive item, goes into that calculation expressly.
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 defense in Barcelona.
