Provisional release, bail and other precautionary measures in Spain

Updated to LO 1/2026 and LO 1/2025 · Reviewed July 2026 · Author: Francisco Javier Martín Porras, criminal lawyer and court expert · SCJE team

Between full liberty and pre-trial detention there is an entire catalogue of intermediate measures that secure the proceedings without imprisonment: the obligation to appear, withdrawal of the passport, prohibitions on leaving the country, bail. Structuring them well is what keeps our clients out of prison while they defend themselves. We comment on their regime and on the bonds and attachments that cover pecuniary liabilities.

In brief. In brief. Provisional release may be ordered with or without bail (art. 529 LECrim). Periodic appearances apud acta are the star measure: the 1st and 15th of each month at the court. Withdrawal of the passport and the prohibition on leaving the country neutralise the risk of flight. The bond of art. 589 secures civil liabilities: it is different from release bail.

Securing the proceedings without imprisonment

Between full liberty and pre-trial detention the LECrim offers a complete catalogue of intermediate measures: the obligation to appear periodically before the court (apud acta), withdrawal of the passport, prohibitions on the issuance of travel documents or on leaving the territory, and bail in its various classes. Provisional release lasts as long as the case requires and, like every precautionary measure, is reviewed when circumstances change: the golden procedural rule is that prison is the exception and liberty the rule (art. 528 LECrim).

Our defence work consists of proposing a credible precautionary package as an alternative to detention, fighting for bail amounts proportionate to real economic capacity (an unattainable bail is disguised imprisonment), requesting the modification of measures as the proceedings advance and the risk declines, and recovering bonds and lifting attachments at the close of the case.

Provision by provision

The precautionary catalogue, article by article

Art. 528 LECrim

Nature and duration

Provisional release lasts as long as the case requires: like every precautionary measure, it is reviewed when circumstances change. The golden procedural rule: prison is the exception and liberty the rule.
In practice

Permanent review is not rhetoric

Every favourable procedural milestone (exculpatory statement, defence expert report, partial dismissal) is an occasion to request the relaxation of the measures. We do it in writing and with facts: precautionary measures rust in favour of the person enduring them when no one reviews them.
Arts. 529 and 530 LECrim

Release with or without bail

When detention is not appropriate, the judge decides whether release requires bail and its class, weighing the record, the person’s roots and the penalty. Release becomes effective upon posting bail; periodic appearance (apud acta) on the fixed days accompanies it by default.
In practice

Modulating the apud acta appearances

The apud acta appearance admits modulation: from fortnightly to monthly, at the court of the real domicile, even telematic where means exist. An isolated and justified non-appearance (work, illness) should not escalate to detention: we document every absence before it becomes a prosecution argument.
Art. 531 LECrim

Amount of bail

To fix the quality and quantity of bail, regard is had to the nature of the offence, the social condition and record of the investigated person and the circumstances that may influence their interest in evading justice. Bail disproportionate to real economic capacity is appealed: it materially amounts to imprisonment. Bail is fought with papers proving capacity: income, burdens, possible guarantees. The constitutional standard prohibits bail impossible to satisfy (it amounts to disguised imprisonment): when the court fixes symbolically high figures, an appeal with real economic documentation reduces them in a majority of cases.
Arts. 539 and 544 LECrim

Modification of measures and passport

Measures are modified during the case: aggravating them requires a prosecution request and a hearing (art. 539), reducing them may be ordered of the court’s own motion. Withdrawal of the passport and the prohibition on issuing travel documents or leaving the territory surgically neutralise the flight risk of residents with international ties. Aggravation requires a request by the accusing party and an adversarial hearing (art. 539 III): aggravations of the court’s own motion are null save urgency with immediate validation. We invoke it every time a court “hardens” without a hearing: procedure matters as much as substance.
Arts. 589 to 614 LECrim

Civil bonds and attachments

Upon indictment (or, in the abbreviated procedure, upon transformation), the judge orders a bond to secure pecuniary liabilities and, failing that, attaches sufficient assets. Both the amount (which must bear relation to the probable liability) and the specific assets are contested: the family home or the operating accounts of a company admit alternatives.
In practice

Choosing what to offer

The civil bond is calculated on probable liabilities, not on inflated prosecution claims: we request its adjustment with a quantification expert report. And we choose what to offer: a bank guarantee or a non-essential property rather than operating accounts; the attachment of work tools is fought with specific alternatives.
Art. 764 LECrim

Specialties of the abbreviated procedure

In the abbreviated procedure, the securing of liabilities admits the civil rules of the LEC (provisional pensions in insured accidents, intervention of the vehicle): a civil-criminal bridge we use in favour of victims who need liquidity without waiting for the judgment. The provisional pensions of the maximum-amount order in road accidents sustain the victim during the proceedings: as prosecution we request them early; the immediate intervention of the vehicle and the insurer prevents supervening insolvencies. The bridge with the LEC allows registrations and interventions that pure criminal practice forgets.

How we use it in your defence

A credible alternative to pre-trial detention

Original commentary by the firm, checked against the reference work in our library: Ley de Enjuiciamiento Criminal Comentada, Lefebvre-El Derecho, 13th edition, May 2026. Structuring the intermediate measures well is what keeps clients out of prison while they defend themselves: the package must be credible for the court and bearable for the client.

Phase 02

During the investigation: withdrawal of passport or exit prohibitions where flight risk exists; civil bond and attachments upon indictment or transformation (arts. 544 and 589)

Phase 03

Review: relaxation requested at every favourable milestone; aggravation only upon prosecution request and adversarial hearing (art. 539)

Who this guide is for

Situations where the precautionary regime decides everything

Persons facing a detention request

A credible package of intermediate measures (appearances, passport, bail) is the alternative that keeps the client at liberty while the defence is prepared.

💶

Persons with unaffordable bail

The amount must attend to real economic capacity, not only to the gravity of the offence: an unattainable bail turns liberty into imprisonment and is appealed with economic documentation.

Residents with international ties

Withdrawal of the passport and prohibitions on leaving the territory neutralise the flight-risk argument surgically, preserving liberty during the proceedings.

🏢

Companies and professionals under attachment

The civil bond is calculated on probable liabilities, and the attachment of operating accounts or work tools is fought with specific alternatives such as guarantees or non-essential assets.

FAQ

Frequently asked questions on provisional release and bail

What exactly is “signing on the 1st and 15th”?
The apud acta appearance obligation of art. 530 LECrim: presenting yourself at the court (or the one of your domicile) on the fixed days and whenever summoned. Repeated non-compliance allows the measures to be aggravated up to detention. Its spacing (monthly, telematic) can be requested when the proceedings drag on and compliance is exemplary.
I cannot pay the bail set for me. What do I do?
Appeal it: the amount must attend to your real economic capacity, not only to the gravity of the offence; an unattainable bail turns liberty into imprisonment and is argued as such. Real bail (property) or third-party bail may also be offered, and instalments requested. The urgent thing is to appeal in time.
When do I recover the bail?
Release bail, when the case ends or the measure is lifted, save non-appearances that cause its execution. The civil bond of art. 589 answers for pecuniary liabilities: it is returned upon acquittal without civil liability or after paying what is owed. We request the lifting of forgotten bonds and attachments: there is dormant money in many courts.
