Legal Translation

We accurately translate highly specialized legal documents and contracts.

  • We have employees who can speak English, but they are not familiar with the contract writing style and would like to leave it to professionals.
  • Outside of JapanI want to correctly grasp the contents of the contract presented by the business partner without omission.

As overseas transactions have been expanding among companies, there is an increasing need to "get the contract right" or "present to foreign business partners a contract that correctly reflects the company's intentions."

The translation of contract-related documents requires accuracy of translation, highly specialized knowledge, and the legal sense. AIBS provides accurate translations of legal documents and contracts by translators with extensive experience in translating legal documents and contracts, followed by checkers who pay special attention to the accuracy of the text.

Features of AIBS's Legal Translation Service

Experience of Legal Documents and Contracts: More than 2,000 Cases

Translators with extensive experience in translating legal documents and contracts

The quality of a translation depends on the translator's linguistic skills, specialized knowledge, and ability to meet various requirements. Especially in the translation of contracts, simply replacing the language may result in a translation that loses its legal effect, which requires an understanding of the laws of the country and international laws to prevent such cases. In our translation service of legal documents and contracts, we provide translations by translators with a background in the legal field or extensive experience in translating legal documents and contracts.

Workflow compliant with international standards

ISO 17100 certification logo

AIBS has aquired the certification of ISO 17100, an international standard for translation services. This certification guarantees that AIBS is capable of providing high-quality translation services using human and technical resources and processes that meet the requirements of the standard.

In the translation of legal documents and contracts, a different checker from the translator checks the source and target texts against each other, sentence by sentence, to ensure consistent translation quality.

Customer Voices


Electric power business-related company

We had a large number of contracts required by a new contractor, and AIBS was able to promptly translate them for us.
We had a meeting based on the translated contracts, and thanks to AIBS, we were able to successfully conclude the contract.


Precision equipment manufacturer

We asked for a translation to help us understand the content. Since we were on a tight deadline, we asked them to deliver only the translation without checking at first, and later to deliver all the translated documents with final checking. Their flexible response was helpful. We also appreciated the supplementary explanation of the terms of the translated contract in their translator's message related to the translation.
