Evidence in Criminal Proceedings: How It’s Gathered and Used in Vietnam in 2025

When you’re caught up in a criminal proceedings in Vietnam—whether as a suspect, defendant, or victim—evidence is the backbone of everything. It’s what decides if a case moves forward, falls apart, or lands someone behind bars. For foreigners navigating Vietnam’s legal system, understanding how evidence is collected and judged can feel like cracking a code, especially with rules rooted in the 2015 Criminal Procedure Code (updated in 2021). This guide breaks it down simply, with real examples to show how it plays out. We’ll also touch on how La Défense Law Firm can help you make sense of it all and use it to your advantage.

Why Evidence Is the Key

In Vietnam, where over 70,000 criminal cases were processed in 2023 according to the Ministry of Public Security, evidence isn’t just important—it’s everything. It’s the difference between a quick release and a lengthy trial, between freedom and conviction. For foreigners—tourists, expats, or business owners—the stakes are high, and the process can seem murky with language barriers and unfamiliar laws. Knowing how evidence is gathered and what makes it count can give you a fighting chance, whether you’re defending yourself or seeking justice.

How Evidence Gets Collected in Criminal Proceedings

Evidence doesn’t just appear—it’s hunted down systematically by authorities like the police, People’s Procuracy, or investigation agencies. Here’s how they do it:

Witness Statements: People who saw or know something are interviewed. In a 2024 theft case in Hanoi, a shopkeeper’s account of a foreign tourist grabbing goods kicked off the investigation.
Physical Items: Think fingerprints, stolen goods, or weapons. Police seized a knife in a 2023 assault case, linking it to the suspect via DNA.
Documents and Digital Data: Bank records, emails, or phone logs often seal the deal. A 2024 fraud probe used a suspect’s text messages to prove intent.
Searches and Seizures: Homes, offices, or phones can be searched with a warrant. In a 2023 drug case, police raided an expat’s apartment, finding hidden stash.

The law sets a tight frame—initial collection happens within 2 months of a case starting, extendable to 4 for complex crimes. Authorities can’t just grab anything; they need reasonable suspicion and proper approval. But slip-ups happen—unlawful searches get evidence tossed out, a point lawyers pounce on.

Who’s Involved in Gathering It

It’s not a free-for-all. Specific players handle evidence:

Police: They’re the frontline, collecting most physical and witness evidence during investigations.
Procuracy: This oversight body double-checks the process, ensuring it’s legal, and can order more collection if needed.
You and Your Lawyer: Defendants or victims can submit evidence too—like alibis or receipts. In a 2023 tax case, a foreign business owner’s lawyer handed over shipment logs, disproving evasion claims.

For foreigners, this stage is tricky—evidence might be in Vietnamese, or you might not know what to offer. La Défense steps in here, digging up what matters and presenting it right.

What Makes Evidence Admissible in Criminal Proceedings

Not all evidence flies in court—it has to pass a test. Vietnam’s system is strict about admissibility, balancing fairness and order. Here’s what counts:

Legally Obtained: Evidence from illegal searches—like a warrantless phone grab—is out. A 2024 case saw a drug charge dropped when police skipped protocol.
Relevant: It must tie directly to the crime. A suspect’s old speeding ticket won’t sway a theft case.
Reliable: Shaky witness stories or tampered items get sidelined. In 2023, a blurry CCTV clip was rejected in a robbery trial.
Properly Documented: Every piece needs a paper trail—where it came from, who handled it. Mess this up, and it’s inadmissible.

Courts lean on this rigor—about 8% of evidence was excluded in 2023 for procedural flaws, per judicial stats. For foreigners, spotting these flaws can turn a case around, but it takes know-how.

How Evidence Shapes the Case

Once collected and deemed admissible, evidence drives the outcome. During investigation, it decides if prosecution happens—weak evidence, and the case stalls. At trial, it’s the judge’s focus; Vietnam’s 95% conviction rate (2023 data) shows how strong prosecution evidence usually is. But it’s not one-sided—your evidence can counter theirs.

Take a 2024 fraud case: a foreign defendant faced cooked books. Their lawyer presented timestamped emails proving legit deals, swaying the judge for acquittal. Evidence isn’t static—it’s a battleground where strategy matters.

Challenges for Foreigners

Foreigners face extra hurdles here. Evidence like witness statements might be in Vietnamese, leaving you guessing what’s against you. Digital data—say, a WeChat log—can be misinterpreted without context. Time’s tight too; you’ve got days to submit counter-evidence once summoned, and missing it hurts. A 2023 tourist in a vandalism case didn’t know to offer a hotel receipt as an alibi—by the time they did, it was too late.

Cultural gaps sting too—Vietnam values confessions, so evidence of remorse can outweigh denial. La Défense bridges this, translating fast and framing evidence to fit local expectations.

Fighting Back: Your Role with Evidence in Criminal Proceedings

You’re not just a bystander. The law lets you:

Challenge Evidence: Call out illegal collection or shaky sources—your lawyer can get it thrown out.
Submit Your Own: Photos, texts, or witnesses can flip the script. A 2024 theft suspect used a GPS log to prove they were elsewhere.
Request Experts: For tech or forensic evidence, you can ask for analysis—though it’s on you to push.

In a 2023 assault case, a foreign defendant’s lawyer debunked a witness’s timeline with phone records, avoiding conviction. La Défense’s sharp eye catches these openings, turning evidence into your shield.
