Why Does High-Quality Legal Translation Matter So Much?

When the people involved in a case speak different languages, legal translation enables courts to hear it — playing a vital role in promoting judicial fairness. From family court to major criminal trials, countless proceedings depend on legal translation to ensure cases proceed fairly for everyone involved.

The cost of language failure

One of the best-known cases of legal translation failure comes from Canada: in 2012, a Hindi-speaking Indian citizen stood trial in proceedings where the court interpreter made repeated errors translating witness testimony — errors that ultimately led the superior court to declare a mistrial.

In another case in the United States, police used Google Translate at the scene to communicate with a limited-English speaker and obtained consent to search a vehicle. When the case reached court, the judge ruled that machine translation was an insufficient basis for valid consent and granted the motion to suppress the evidence.

How law firms choose translation support

Law firms handling multilingual cases typically have several options: professional translation agencies, with global networks of translators and interpreters, are long-term trustworthy partners; freelancers cost less, but agencies offer more flexibility in backup staffing and multilingual support. As for machine translation — as the rulings above show, it should be avoided in legal settings.

How to avoid losing a case to translation

Translators and interpreters must convey case details accurately and concisely. As a best practice, law firms should engage professional linguists before a case begins rather than searching at the last minute. The right legal translation support not only avoids adverse judgments — it avoids the time and cost of retrials.
