Finland: notarial and documentary services

How someone in Finland can get documents legalised, witnessed or certified, take an oath of British citizenship and obtain informative notes.

Please note that notarial and document services are currently restricted as a response to the coronavirus (COVID-19) situation.

If you think you have an urgent need for a notarial service, please contact 09-22865100 option: consular services.


The British Embassy can provide a range of notarial and documentary services for British nationals in Finland.

Where local notaries can provide services, the British Embassy will not provide them. In many cases local notaries or lawyers can provide services more cheaply, quickly and conveniently.

You must make an appointment for each service that requires your personal attendance. Use the links after each service to make a reservation. A member of staff will contact you to confirm your appointment.

Before booking, make sure you have selected the correct service and that the document will be accepted by the relevant authority. This could be the local town hall, registry office, tax authorities, immigration office or another authority either in Finland, the UK or a third country.
