Reliable legal translation services: What are your options?

In the market for legal translation services? Get an overview of 5 go-to service providers, as well as tips on how to pick the best one for your needs.


In 2011, the South Korean government demonstrated firsthand the importance of accurate, meticulously reviewed legal translations. It was forced to revisit the translation of a free trade agreement not once, not twice, but three times due to an accumulation of over 200 translation errors.

As you can imagine, this resulted in public embarrassment and delayed agreement discussions. But South Korea was also said to have spent the equivalent of over $27,000 on an ineffective third-party review of the translation that was supposed to ensure its accuracy.

This is just one example of how not having the right people and processes in place when translating legal documents can be costly. The key to avoiding these and worse issues is to choose your legal translation services wisely, but what should you look for?

What to consider when choosing a legal translation service provider

Here are five things you should evaluate when considering a legal translation company:

  1. Quality control processes. Even the smallest errors can have serious legal implications, resulting in delayed proceedings, disputes, or even litigation. No matter what, the service provider you choose must be equipped to catch and correct issues before they cause commotion. Look for indicators of strong quality control processes, such as ISO certifications, multi-step translation reviews by several linguists, quality guarantees, and the use of artificial intelligence to automate quality checks.
  2. Subject matter expertise. Of course, linguistic expertise and even a strong understanding of legal systems, concepts, and terminology are important. But, for the sake of translation accuracy, it’s often also critical for translators to be familiar with your particular industry or domain.
  3. Security and confidentiality. Investigate the policies and protocols of any legal translation agency you’re considering, specifically regarding document handling and data security. Make sure your data is encrypted, and get non-disclosure agreements signed to keep your information secure.
  4. Speed and turnaround time. Fast turnarounds are often essential for legal documents, so ask about average speeds and the availability of rush delivery options when needed.
  5. Translation memory technology. Translation memory improves consistency across your legal documents and other texts generated by your company. Not to mention that it enables faster translation workflows, and also reduces translation costs, so you don’t have to pay for translations you’ve already approved in the past.
