CRIMINAL LAW
Crime is inherent in the reality of every society, and Colombian society is no exception. As a citizen, do you know how to act and what to do when faced with such a situation?
What is a criminal complaint?
It is the formal act by which a person informs the authorities that an offense has been committed. The Código de Procedimiento Penal (CPP) provides that "every person must report to the authorities the offenses of whose commission they are aware" (art. 67), and anyone may file it, not only the victim.
However, it does not always work the same way: there are important exceptions and differences. For example, no one is obligated to report against themselves, their spouse, partner, or relatives.
In addition, there are offenses that are not investigated ex officio but only at the victim's request —the so-called private-action or querellable offenses: in those cases the investigation and the trial usually begin only if the querella (the victim's formal complaint) is filed. The querella is subject to a time limit: it must be filed within the six (6) months following the commission of the punishable conduct (art. 73 CPP), except in cases of proven force majeure or fortuitous event.
Outside these situations, failing to report an offense when there is a duty to do so is punished by law. The Código Penal punishes the failure of a private individual to report: anyone who, knowing of the commission of extremely serious offenses such as genocide, enforced disappearance, torture, homicide, kidnapping or drug trafficking, fails without just cause to inform the authorities immediately, incurs imprisonment of three (3) to eight (8) years (CP art. 441). Also punished is anyone who, by reason of their position, occupation or activity, learns of the use of minors for the commission of offenses and fails to report it while having a legal duty to do so (CP art. 219B). On this point, the Corte Constitucional struck down the expression "de doce (12) años" ("aged twelve (12)") in article 441 —introduced by article 18 of Ley 1121 de 2006—, so that today the reinforced duty to report protects every minor under 18 (Sentencia C-853 de 2009).
Filing a criminal complaint is the first step for the State to investigate and sanction the commission of a crime. The complaint is the most used means to express knowledge
By reporting, the constitutional duty of the State to investigate and criminally prosecute the act is activated (CPP Art. 66). That is why it is crucial to draft it completely and truthfully: a
Art. 67 — Ley 906 de 2004 (Código de Procedimiento Penal)Every person must report to the authorities the offenses of whose commission they are aware and which must be investigated ex officio.
The complaint may be filed orally, in writing, or even through electronic channels (CPP Article 69), provided it allows identification of the complainant. It must include precise information: the complainant's name (with ID), date and time of filing, and a clear, detailed account of the events that occurred.
For example, you may go to a Fiscalía (Prosecutor's Office) or a Comisaría, call the helplines (122, available 24/7), or use the "Denuncia Fácil" online platform on the Fiscalía website. Beyond the exception of the anonymous complaint, in every case the complainant must be duly identified (cédula or identity document) and must sign the written complaint; if they cannot sign, they may leave their fingerprint.
The official who receives the complaint will process it immediately, will record the information in the system (generating the NUNC) and will refer the case to the corresponding prosecutor.
Where to file a criminal complaint
Preferably before the Prosecutor General's Office (Fiscalía General de la Nación) — duty office or local prosecutor offices — or any National Police station that receives complaints.
Every Police Station and CAI has the obligation to receive the complaint and forward it to the Prosecutor's Office. The Prosecutor's Office and the Police operate 24 hours, year-round,
In addition, the Prosecutor's Office offers online channels that allow reporting without needing to travel.
| Channel | How to access it | Availability |
|---|---|---|
| Fiscalía General — in-person office | Duty office or local Fiscalía offices | 24 hours / 365 days |
| Policía Nacional — station or CAI | Any station or Comisaría | 24 hours / 365 days |
| Line 122 | Telephone call | 24 hours / 365 days |

What the complaint must include so it is not weak
When drafting the complaint it is advisable to explain clearly what happened, how it happened and who was involved (if known). Recount the facts in chronological order and note specific dates and places; avoid speculation and be precise. Attach all the evidence or indications you have —contracts, receipts, photos, videos, messages, bank statements, medical reports, expert opinions and the names and telephone numbers of witnesses— because that makes it easier for the Fiscalía to verify what happened and to direct the investigation.
That is why it is usually very useful to have the representation of a lawyer for victims who can help you organize the information, identify the relevant evidence and draft the complaint properly; good support improves the quality of the complaint and, consequently, the direction the investigation will follow.
DOCUMENTS TO GATHER BEFORE FILING A COMPLAINT
- Identity document (cédula or passport)
- A written account of the facts in chronological order (dates, times, places)
- Contracts, receipts or documents proving the relationship with the alleged perpetrator
- Photos, videos or screenshots recording the incident
- Relevant messages (SMS, WhatsApp, email)
- Bank statements or proof of payment (in offenses against property)
- Medical reports or expert opinions (in cases of injuries or damage to property)
- Names, telephone numbers and address of possible witnesses
What happens after filing the complaint
If the person filing the complaint is not the victim, generally they do not become part of the criminal process and do not automatically have the right to receive notifications about the progress of the investigation.

In contrast, when the person who reports is the victim, they do have procedural rights: they must be informed about the progress of the process, may submit evidence, and provide testimony. protective measures for domestic violence operates even in parallel with the criminal complaint before the Fiscalía. It is worth recalling that domestic violence is no longer an offense requiring a querella: since Ley 1542 de 2012 it is investigated ex officio, and neither conciliation nor withdrawal is available. Inasistencia alimentaria (the offense of withholding legally owed support) also ceased to require a querella and is prosecuted ex officio, but it retains a special treatment: Ley 1826 de 2017 brought it into the special abbreviated criminal procedure and, where the victim is an adult, it remains conciliable as a procedural prerequisite (arts. 74 and 522 CPP); where the victim is a minor, the law excludes the requirement of a querella (art. 74 CPP) and therefore conciliation is not available as a condition for investigating.
Additionally, the victim may have a lawyer to receive notifications, accompaniment, and ensure the protection of their rights during the investigation.
Sentencia C-209 de 2007 — Corte Constitucional (M.P. Manuel José Cepeda Espinosa)The Corte Constitucional made clear that, in the Colombian adversarial criminal system, the victim does not have the status of party within the proceeding, but rather that of special intervener (interviniente especial). Under that status, the victim may exercise specific powers autonomously vis-à-vis the prosecutor —such as requesting the early taking of evidence before the juez de control de garantías (the judge who oversees constitutional guarantees at the pre-trial stage), requesting the disclosure of specific items of evidence, and going directly to the competent judge to request protection measures—. The Court based these powers on the fact that the victim's rights to truth, justice and full reparation are protected even in a system of adversarial character. C-209/2007 — the victim as a special intervener.
Reporting a crime is a citizen right and duty. Doing so clearly, completely, and honestly is essential for justice to act. Before reporting, inform yourself of your rights and gather evidence.
Act with responsibility, but without fear: provide truthful evidence and cooperate with the investigation. Remember that not reporting may also have legal consequences (Art. 67 CPP, Art. 219B and 441 of the Criminal Code).
Finally, file your complaint before the competent authority and keep the documentation (copies, evidence, NUNC number) in case it is required. The Prosecutor's Office is required to receive every well-founded complaint and to investigate it. By providing truthful and timely information, you will be contributing to the fight against crime and to the protection of victims' rights. criminal lawyers in Bogotá who will assess the nature of the act and guide the procedural strategy.
