Legal Assistance To the Detainee: What It Includes

Legal assistance to the detainee: what it includes

When someone is detained by the police, the first thing they must do —before answering any question, before signing any document, before trying to “clarify” anything— is to request the presence of their lawyer. This right, expressly recognized by the Constitution and developed by the Criminal Procedure Act, is the most powerful guarantee available to the detainee to protect their position from the very first moment.

However, many people are not clear about what it exactly means to have a lawyer during detention. What can that lawyer do? Can they prevent me from making a statement? Can they access all the information about my case? What happens if a court-appointed lawyer arrives whom I do not know? These questions are frequent and legitimate, and their answers are more important than many believe.

Legal assistance to the detainee is a right with concrete and enforceable content, not an empty formality. It comprises a set of specific actions that the lawyer must carry out to ensure that the detention is conducted with all legal guarantees and that the detainee does not compromise their procedural position before the criminal process has even formally begun. In this article we explain everything that this right includes, how it must be exercised, and what consequences its violation has.

The legal basis of legal assistance to the detainee

The right to legal assistance during detention is recognized in Article 17.3 of the Spanish Constitution, which guarantees that every detained person has the right to the assistance of a lawyer in police and judicial proceedings. This constitutional right is developed in detail in the Criminal Procedure Act, reformed in this respect by Organic Law 5/2015, which incorporated into Spanish law the requirements derived from Directive 2013/48/EU on the right of access to a lawyer in criminal proceedings.

This reform significantly strengthened the content of legal assistance, establishing precisely what actions the lawyer must carry out during detention and what minimum guarantees must be present for that assistance to be considered effective. The mere physical presence of the lawyer at the police station is not sufficient: the law requires active and substantial participation by the lawyer in defense of the detainee’s interests.

Failure to comply with any of the essential elements of legal assistance has direct procedural consequences: a statement given without these guarantees may be declared null and void and excluded from the criminal process, which can have a decisive impact on the outcome of the investigation.

The right to choose a lawyer of trust

The first element of legal assistance is the detainee’s right to freely appoint the lawyer they consider most suitable for their defense. The police are obliged to facilitate the necessary means for the detainee to contact their chosen lawyer: providing a telephone, facilitating the number if needed, and waiting for the lawyer’s arrival before proceeding with any questioning.

This right to choose a lawyer has enormous practical importance. The lawyer who assists the detainee in the first hours of detention is not a mere formality: they are a key element of the defense strategy that can condition the entire subsequent process. A specialized criminal lawyer who knows the detainee, who has been able to speak with them before detention, or who joins the case quickly and with knowledge of the file can make a fundamental difference in how that first statement is handled.

If the detainee does not have a trusted lawyer or cannot contact one in the available time, they have the right to free legal assistance through the Bar Association, which will appoint a duty lawyer. This lawyer has the same obligation to provide effective assistance as any private lawyer, although in practice the quality of that assistance may vary depending on the experience and dedication of the appointed professional.

The confidential interview prior to the statement

One of the most important and protective elements of legal assistance is the right to a confidential interview with the lawyer before making any statement. This interview must take place under conditions of real privacy: without police officers being able to listen, record, or be present. It is the space in which the lawyer can advise the detainee with complete freedom, without any external pressure.

During this prior interview, the lawyer must carry out a series of essential actions:

• Explain to the detainee what rights they have at that moment and how to exercise them correctly.
• Inform them of the facts they are accused of and the reasons for the detention, to the extent that this information is available.
• Advise them on whether or not it is advisable to make a statement, and on what to say and what to remain silent about if they decide to do so.
• Explain the legal consequences of the different available options: making a statement, remaining silent, or answering only certain questions.
• Warn them that everything they say may be used against them in the subsequent criminal process.
• Obtain from them the information the lawyer needs to exercise their defense effectively from that first moment.

This interview does not have a legally established minimum duration, but it must be sufficient for the lawyer to properly fulfill their function. If the police interfere with the interview, interrupt it unjustifiably, or prevent it from taking place in conditions of privacy, that irregularity may affect the validity of the subsequent statement.

The presence of the lawyer during questioning

Once the prior interview has concluded, the lawyer has the right —and the obligation— to be present throughout the entire police questioning. Their presence is not merely symbolic: the lawyer has an active role that includes a series of specific actions expressly recognized by law.

Objecting to improper questions
The lawyer can and must object to questions they consider illegal, irrelevant, or coercive. This includes questions that indirectly induce self-incrimination, leading questions that assume unproven facts, or any question that violates the detainee’s rights. When the lawyer raises an objection, it must be recorded in the statement record, which may be relevant if nullity is later alleged.

Requesting clarification of questions
If a question is ambiguous, confusing, or open to multiple interpretations, the lawyer may request that it be reformulated more precisely before the detainee answers. This is especially important in technically complex interrogations or where the wording of the question may lead the detainee to incriminate themselves unintentionally.

Ensuring proper conditions of the statement
The lawyer has the obligation to verify that the statement is being conducted under appropriate conditions: that the detainee is not subjected to any form of physical or psychological pressure, that they understand the questions, that they are in a sufficient physical and mental state to testify, and that the record faithfully reflects what the detainee has stated. If irregularities are detected, they must be recorded at that moment and communicated to the judge as soon as possible.

Advising the detainee on each answer
Although the lawyer cannot answer on behalf of the detainee, they can briefly advise them before each answer, especially when the question is compromising or the answer could be harmful. This in situ advisory role is one of the most important guarantees of effective legal assistance, as it prevents the detainee from facing questions unprepared.

Verification of the statement record

At the end of the questioning, a record is drawn up containing the content of the statement. This document has enormous procedural importance: it may be used in the subsequent criminal process to verify consistency between what was stated to the police and what is later stated before the investigating judge.

The lawyer has the obligation to read the entire record before the detainee signs it and to verify that its content faithfully reflects what the detainee has declared. If the record contains errors, omissions, or wording that distorts the meaning of the answers, the lawyer must request that they be corrected before signing. If the police refuse to make corrections, the lawyer may record their disagreement and the detected errors in the record itself.

The detainee should never sign a record that has not been reviewed by their lawyer or whose content does not exactly correspond to what they have stated. An impulsive signature or one given under pressure may create significant difficulties for the defense in later stages.

Legal assistance during the appearance before the judge

Legal assistance does not end when police questioning concludes. The lawyer must continue assisting the detainee during the appearance before the duty investigating judge, which is the act in which the judge decides whether the detainee will be released or placed in pre-trial detention.

This appearance is, in many cases, the most critical moment of the entire detention. The judge will hear the arguments of the police and the prosecutor in favor of pre-trial detention and the arguments of the defense lawyer to the contrary, and will make a decision that may deprive the detainee of their liberty for weeks, months, or longer. A well-prepared lawyer, who knows the case and argues with solidity and precision, may obtain provisional release where a less prepared lawyer would not.

During the hearing, the lawyer must oppose pre-trial detention with reasoning if they consider that the legal requirements are not met, propose less restrictive alternative measures —bail, obligation to appear, withdrawal of passport— and argue why the detainee’s situation does not justify deprivation of liberty. If the judge orders pre-trial detention, the lawyer must urgently appeal that decision before the Provincial Court.

Court-appointed lawyer vs. trusted lawyer: practical differences

A question that generates much uncertainty concerns the real differences between being assisted by a duty lawyer and by a trusted criminal lawyer contacted by the detainee or their family.

From a legal standpoint, both have the same obligations and rights during legal assistance. The law does not establish differences in the content of the assistance to be provided. However, from a practical standpoint, the differences may be significant:

A trusted lawyer usually has more time to prepare before arriving at the police station, especially if the detainee or a relative has been able to contact them from the outset. They may arrive already knowing what type of offense is being investigated, what initial strategy may be appropriate, and what aspects of the detainee’s situation are relevant for the defense.

A duty lawyer, by contrast, arrives without prior information, must familiarize themselves with the situation in the limited time available before questioning, and may be assisting several detainees simultaneously during their shift. This does not necessarily mean their assistance is deficient, but the conditions under which they must perform it are more difficult.

For this reason, whenever possible, it is advisable that the detainee or their family contact a trusted criminal lawyer from the very beginning, without waiting for the Bar Association to appoint one. The minutes gained in this initial phase can be decisive.

What the lawyer must do after assisting the detainee

The lawyer’s work does not end when the detainee is released or brought before a judge. Legal assistance to the detainee is the starting point of the criminal defense, not its endpoint. From that moment, the lawyer must take a series of measures to ensure that the actions carried out during detention are rigorously examined and that any irregularity is identified and challenged at the appropriate procedural moment.

Firstly, the lawyer must analyze the statement record and verify whether its content is fully consistent with what the detainee stated. Secondly, they must review whether the detention procedure complied with all legal requirements: whether rights were communicated, whether time limits were respected, whether the prior interview took place in conditions of privacy. Thirdly, they must plan the defense strategy for the subsequent phases of the process, using the information obtained during detention to build a solid defense from the outset.

Frequently asked questions

Can the lawyer prevent me from making a statement to the police?
The lawyer cannot prevent you from making a statement if you decide to do so, because the decision to speak or remain silent is yours alone. What they can —and must— do is advise you on whether it is advisable to make a statement at that moment, what the advantages and disadvantages of each option are, and how to manage the statement if you decide to give one. In many cases, the lawyer will recommend remaining silent before the police, especially when the charges are not well known or when any explanation could be harmful. But the final decision always belongs to the detainee, and the lawyer must respect it even if they disagree.

What happens if the police question me before the lawyer arrives?
If the police conduct questioning before the lawyer arrives or without their presence, that questioning may be declared null and the statement obtained cannot be used as evidence in the criminal process. It is a serious violation of the right to legal assistance that must be communicated to the lawyer as soon as they arrive, so that they can take the necessary measures: record the irregularity in the statement, request nullity before the judge, and preserve all possible evidence of what occurred.

Can the lawyer speak with the officers to find out what I am accused of before the prior interview?
Yes. The lawyer has the right to obtain information about the reasons for detention and the facts attributed to their client before the prior interview, in order to advise them with the greatest possible information. The police are obliged to provide this information to the lawyer insofar as it does not harm the investigation. In practice, the degree of information provided may vary, but the lawyer must always try to obtain as much information as possible before meeting with their client, so that the prior interview is as useful and specific as possible.

Does the lawyer have access to the police report during detention?
The lawyer’s access to the police report during the detention phase is limited. The police are not obliged to provide a full copy of the report to the lawyer during detention, although they must provide basic information about the alleged facts. Full access to the file —including the report, expert opinions, and investigative actions— usually occurs once the case reaches the court and the lawyer can access the judicial proceedings. This limitation highlights the importance of making the most of the prior interview to obtain all possible information directly from the detainee.

What happens if the duty lawyer does not arrive within a reasonable time?
If the duty lawyer does not appear within a reasonable time —usually a few hours from the request— the police must notify the Bar Association so that another lawyer can be appointed more quickly. During this waiting period, the police cannot proceed with questioning under any circumstances: the detainee’s right to be assisted before making a statement is absolute and cannot be bypassed due to delays in appointing a duty lawyer. If questioning takes place before the lawyer arrives due to such delay, that statement may also be challenged for violation of the right of defense.
