For a written document, ask for a translator

A translator works with written text, such as a certificate, contract, letter or report. The result is a written translation in the required language. The translator needs the source text, its purpose and any instructions about terminology or format.

Urgent Vertalen arranges document translations. For an official submission, tell us whether the recipient requires a sworn translation and which language and delivery format it accepts.

For a conversation, ask about interpreting

An interpreter supports communication between people using different languages during a conversation or event. This can involve spoken languages, a spoken and a signed language, or two signed languages. The languages, setting and interpreting method need to match the situation.

In consecutive interpreting, the interpreter delivers the message after the speaker has finished a passage. In simultaneous interpreting, the interpretation takes place while the person is speaking, usually with suitable equipment. The European Commission explains these different methods in its interpreting guidance.

Confirm the requirements for an official appointment

Ask the court, notary or other organisation hosting the appointment whether interpreting is needed and what qualifications it requires. Arrange the appropriate professional for that specific setting. Do not assume that a written translation replaces interpreting at the appointment.

A translator’s and an interpreter’s skills are distinct. If both services are needed, check each separately. The Bureau Wbtv register overview (in Dutch) provides information about registered sworn translators and interpreters in the Netherlands; registration details should match the required service and language.

You may need both services

For example, an organisation may ask you to submit a translated document before an appointment and separately arrange interpreting for the conversation. Keep the document requirements and appointment arrangements in separate parts of your brief.

Our explanation of sworn and certified translations covers the written-document terminology. For a contract or deed, see our legal translation service.

Arrange the written translation you need

Request your no-obligation quote for your written documents. Include the source and target languages, recipient’s requirements and deadline so our advisers can confirm the scope, price and delivery time.

Before sending your files, use our overview of translation services to identify the relevant document service. For more on interpreting methods and signed languages, read the European Commission’s interpreting guidance.
