Under arrest: what to do (and what not to do) in the first 48 hours

ref. zam-2026-001by Paul David Zabala Aguilar · Founding Partnerapril · 2026

An arrest is one of the most distressing moments a person or their family can go through. Amid the fear, it is easy to make mistakes that end up weighing on the entire process. The good news is that Colombian law establishes clear rules and rights that protect you from the very first minute. Knowing them makes all the difference.

The 36 hours that change everything

Except in cases of flagrancia (caught in the act), no one may be deprived of liberty without a written order from a competent judicial authority. And whatever the reason for the arrest, every person must be brought before a juez de control de garantías (pre-trial supervision judge) within the following 36 hours.

At that hearing the judge reviews whether the arrest was lawful, the Prosecutor's Office may formally bring charges, and a decision is made on whether a precautionary measure applies (which may or may not involve detention). In other words: much of what comes next is decided in those first hours. That is why a technical defense must be activated immediately — not "later."

Your rights from the moment of arrest

What to do

What NOT to do

Why the first hours matter so much

Those first hearings determine whether the arrest stands, what offense you are charged with, and whether you will face the process at liberty or in detention. A defense present from the start can challenge the lawfulness of the arrest, contest the precautionary measure and protect your rights before it is too late.
