Legalisation Guide for Clients
To legalise is to make something lawful or legal, to confirm or validate it. Use our free legalisation tool to check the legalisation requirements, or contact us for swift end professional assistance.
In the context of documents signed in the UK for use overseas, some countries require further affirmation of their validity. That is when the documents need to be legalised before they will be accepted in the receiving country.
In order for a document to be legalised by the competent authority, in most instances the document (and/or the act of it being executed, signed or sworn by the signatories) needs to be notarized by a notary public. The notary’s signature and seal is then legalised by the competent authority.
FCDO Apostille / Legalisation
The Apostille or Legalisation certificate is a verification from the Foreign and Commonwealth Office (FCDO)* of the notary’s authority to sign. Many countries require this formality. Some go further and require the consulate / embassy to also legalise (authenticate) the notary.
*For more information on FDCO legalisation see “read more” section below.
As a general rule of thumb:
- Countries connected with UK – basic notarisation (i.e. Australia)
- EC and Hague Convention signatories – Apostille
- Middle East countries and most Asian Countries – mainly Apostille and Consulate (i.e. UAE and Vietnam)
