Notarial and Documentary Services Guide for Thailand

Documents, certificates, letters and notes available at the British Embassy in Thailand.


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

Where local notaries can provide services, the British Embassy Bangkok 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. Please use the relevant links to make an appointment.

Before booking, please make sure you have selected the correct service and that the document will be accepted by the relevant authority. This could be the local district (Amphur), registry office, tax authorities, immigration office, ministries or another authority either in Thailand, the UK or a third country.

Legalisation is the official confirmation that a signature, seal or stamp on an official public document is genuine. UK public documents such as birth, death, marriage and divorce certificates can be legalised by the UK government in the UK. This is also known as an apostille.
