Answering your queries

Frequently asked questions

Clear guidance on validity, document requirements, confidentiality and processing times.

What is a sworn or certified translation?

It is completed by a translator authorized by a judicial authority and issued with a formal certification statement, registry details, seal and signature.

Are your sworn translations legally accepted abroad?

Acceptance depends on the receiving authority. We confirm the expected certification, apostille or legalization format before quoting.

What is the difference between an apostille and a sworn translation?

A sworn translation certifies the translated text. An apostille authenticates the origin of a public document or signature for use in another country.

Do I need to send original physical documents?

Usually a clear scan is enough for review. We will tell you if an authority requires the original.
