This outlines the obligations, rights and potential liabilities that apply when acting as a witness in legal proceedings in Spain. Whether you are testifying in a criminal, civil, labour or administrative case, the same broad rules apply under Spanish procedural law.

1. Legal obligation to testify

Under Spanish law, anyone summoned by a court or tribunal has a legal obligation to appear as a witness. Article 410 LECrim requires anyone residing in Spain who is not legally exempt to appear in court when summoned and testify truthfully about what they know. Article 292 LEC sets a similar obligation in civil proceedings. Failing to appear without a justified reason can result in a fine or other coercive measures.

2. Obligation to tell the truth

Article 433 LECrim requires witnesses to testify truthfully; lying under oath is a criminal offence. Article 458 of the Penal Code sets the penalty for a witness who knowingly lies under oath in criminal proceedings at six months to two years in prison, rising to four years in more serious cases. This also applies to written statements given under oath before judicial authorities.

3. Staying consistent with previous statements

If you have given testimony before, for example during a police investigation or an earlier hearing, it is worth reviewing your prior statements beforehand where possible, keeping your account consistent, and explaining clearly to the court if anything has changed, to avoid any suspicion of contradiction.

4. Right against self-incrimination

Article 24.2 of the Spanish Constitution gives everyone the right not to incriminate themselves. If a question would place you at risk of criminal liability, you can refuse to answer it or request legal protection.

5. Right to be treated with dignity and without pressure

Witnesses must be treated respectfully and protected against coercion or manipulation. Article 416 LECrim also lists relatives of the accused who are exempt from testifying, to preserve family ties.

6. Witness statement protocol

  • Your identity is verified before you testify.
  • You are asked to take an oath, or promise, to tell the truth.
  • Your statement is formally recorded.
  • You may be questioned by the judge, the prosecutor, and lawyers for both sides.

7. Penalties for non-compliance

Refusing to appear, failing to answer truthfully, or attempting to mislead the court can lead to fines or other sanctions, criminal liability under the Penal Code, and further civil or criminal consequences if your testimony causes harm or misleads the court.

8. Protected or vulnerable witnesses

Spanish law provides special measures for witnesses in sensitive cases, such as gender violence, cases involving minors, or organised crime:

  • Anonymity, or voice and image distortion
  • Testimony given by video conference
  • Psychological or legal support during questioning

Final advice for clients

  • Prepare calmly and focus only on what you know directly.
  • Be honest and consistent with any previous declarations.
  • Seek legal guidance if you are unsure or uncomfortable about anything.
  • Do not rehearse or coordinate your statement with others.
  • Stay calm, respectful and professional throughout the proceeding.
