What certified means in practice
In the United States, a certified translation is usually a translation accompanied by a signed statement from the translator or translation company. The statement says the translator is competent in both languages and that the translation is complete and accurate to the best of their ability.
There is no single national license that makes someone a certified translator for all purposes. Some professional associations offer credentials, which may be requested in some cases.
The requesting agency's own definition always wins. If an immigration office says certified, it means a statement of accuracy. If a foreign ministry says certified, it may expect a stamp from an approved translator.
Ask the translator whether the statement can be signed electronically or must be wet ink, since agencies differ.
What the certificate includes
A typical certificate lists the translator's name, contact information, the languages, the date, a description of the document, and a signature. Some also add a statement of qualifications. It is attached to the translation and, ideally, to a copy of the original.
The translation should mirror the original layout and include stamps, seals and handwritten notes, marked as such.
Include a copy of the source document so the reviewer can compare it. Without the source, a reviewer may reject the translation as unverifiable.
Certified, notarized and sworn are different
A notarized translation means the translator signed in front of a notary, who verified the translator's identity. The notary does not check the quality of the translation. A sworn translation is a concept used in some other countries, where a court-registered translator has authority.
Check which one the requester wants. Many agencies accept a certified translation without notarization.
Some agencies also accept a translation certified by a translation company, with the company's letterhead and an authorized signer. Others want the individual translator's signature.
Who can do the translation
Most agencies do not allow you to translate your own documents, and some restrict relatives. Use a professional or a translation company that provides the certification statement. Ask for samples and turnaround times, and for pricing per page or per word.
Quality matters: names, dates and numbers must be exact, including spelling that matches your passport.
Rates and turnaround vary, and rush service usually costs more. Ask for a quote that lists page counts and any extra charges for formatting or notarization.
Apostille and translation order
For international use, ask whether the apostille goes on the original, the translation or both. Requirements differ, and some countries want the translation completed first. A wrong order can mean redoing steps.
If in doubt, ask the receiving office for written instructions.
Keep a digital copy of the final package for your own records and ask the translator to keep theirs for a period in case a question arises.
Common questions
Can a bilingual friend certify a translation?
Some agencies allow it, many do not. Always check the requester's rules.
Does a certified translation need a notary?
Not always. It depends on the requester. Notarization only confirms the translator's identity.
