Certified German, French, and English Translator

What you're looking for


You may be worried that the translator won’t understand complex legal or financial terminology, so you consider translation skills and subject-matter expertise as equally important when hiring a translator.



You received a large volume of documents from your client and need to figure out which ones must be translated, but you don’t have the time or language skills to do so. The last thing you want is to pay a middleman or spend money on unnecessary work.


You need to get a complicated legal document translated for an upcoming trial. The translation must be certified, and time is of the essence.


You would like to reach out to the translator directly, rather than dealing with ever-changing project managers.


You wish to entrust your confidential documents to one person only and hire them again if needed.



You must make sure that the translation respects all formal requirements as set out by the requesting authority.

“Ms. Diallo produced a certified translation from French into English of the opinion of Mr. Justice Girouard in an old decision of the Supreme Court of Canada, for our use in a matter recently before the Court of Appeal for Ontario (Roe v Roe, 2024 ONCA 179). We were pleased with Ms. Diallo’s fine rendering of this complex piece of legal writing. She handled terms of art, across both civil and common law, with precision, and attended carefully to nuances in the extensive rehearsal of facts in his Lordship’s judgment. By quieting an important legal issue agitated in the English-language appeal in which we appeared, her translation of the only authority from the highest court directly on point enabled us to apportion our time during argument to better advantage than we could without this case to hand. We ultimately prevailed at the hearing and shall have no hesitation to engage Ms. Diallo for future translations.”

Let's bulletproof your documents


I bill my services by the hour or by the project. I also offer discounts for 3- and 6-month retainers. 

Please contact me for a project-specific quote. I accept payments in US dollars, Canadian dollars, and Euros.


Artificial intelligence is becoming a widespread tool to help translators manage large volumes of text. Nuance and tone, however, cannot be recognized or translated by machines. It is also impossible to achieve a consistent text with AI tools. For example, the terms “contract” and “agreement” tend to be used interchangeably—and mistakenly—in machine translations. Lawyers cannot let such errors affect their image. To ensure your texts perfectly reflect the intended meaning, you need a translator who understands and knows how to convey that meaning.

I communicate proactively with clients to understand their terminology and other preferences. My multilingual glossaries and translation memories ensure that translated texts are consistent in terms of expression, tone, and format.

It may sound old-fashioned, but I print complex translations for revision. Despite the help of automated grammar and spell checks, nothing beats reading a text on paper with a fresh set of eyes.

Depending on the level of complexity, the translation is reviewed by a trusted colleague if budget and time constraints permit.

As every document is different, turnaround time can only be determined once I know more about the document. Please contact me to get a quote and an expected turnaround time.

Yes, there is an additional fee for an expedited turn around. 

Ultimately, it’s up to you. I usually send them via email in PDF format, but some clients prefer Word. Besides PDF format, I can also provide certified translations in hard copy.

I accept credit card payments, bank transfers, checks, and Interac e-transfer. 

Yes. If your referral leads to a one-time assignment, you will receive a 15% discount on your next translation. If it leads to a long-term agreement with advance payments, you will receive a 20% discount.
