What is an Apostille?


An Apostille (also known as Hague Apostille) is an official certificate issued in the United Kingdom by the Foreign, Commonwealth and Development Office (FCDO) certifying/attesting public documents for use in another country, pursuant to the Hague Apostille Convention 1961. The Apostille is an abbreviated method of legalisation that certifies/attests to the Solicitor’s signature, Notary Public’s signature and seal OR a signature or seal from a UK government official/department such as from the Courts, HMRC, ACRO Criminal Records Office, NHS (Medical Practitioners), General Register Office (GRO) and Ministers of Religion (Church of England).

In summary, countries that are signatories to the Hague Convention 1961 (Convenzione dell’Aja/Convenção de Haia) have agreed to do away with the lengthy legalisation process via the foreign consulates and embassies and accept documents with the Apostille only as authentic for use in another Signatory country. An Apostille (Apostila dell’Aja/Apostila de Haia) in the UK is issued by the Foreign, Commonwealth and Development Office (“FCDO”) Legalisation Office, in Brazil is issued by the Notary Public Offices (Cartórios) and in Italy by the Prefectures of each Province. In most other foreign jurisdictions, the Apostille is issued by their Ministry of Foreign Affairs.

With an Apostille certification, a notarised/certified document is entitled to recognition in the country of intended use and there is no requirement for further certification or legalisation by the country of recordal’s nearest Embassy or Consulate in the United Kingdom if the exchange of public documents are between the Hague Convention member states.

The Hague Convention 1961

The purpose of the Convention is to abolish the requirement of diplomatic and consular legalisation for public documents originating in one Convention country and intended for use in another.

Documents issued in a Convention country which have been certified by a Convention Apostille are entitled to recognition in any other Convention country without any further authentication/legalisation. Such recognition is an obligation on the part of one country to another country party to the Convention and the courts and authorities have been alerted to this obligation.

Consular officials in Convention countries are prohibited from placing a certification over the Convention Apostille, although, some foreign consulates still do. Please see a list of the countries which are signatories to the Hague Convention and require Apostille only as the method of legalisation. 

Apostille Processing

We provide Hague Apostille legalisation by the UK FCDO Legalisation Office in London (Premium Service) and in Milton Keynes (Standard Service) as well as the online service for the e-Apostille including the digital notarisation which is mandatory for this latter option. 

The processing time via the premium service in London is usually within 5-7 hours if the documentation is received by 11:00 am and via standard service in Milton Keynes is next working day service (guaranteed next-day service if we receive the documents at our office by 11:30 am). Please note that the turnaround time is only guaranteed if the signature of the UK public official who signed/certified the document is registered on the FCDO database. If signature verification query is applicable, the turnaround time depends on how fast the UK public official/Department responds to the FCDO with the specimen signature confirmation. The e-Apostille service usually takes between 2-48 hours to be issued depending on the FCDO workload. 

The electronic Apostille (e-Apostille) is a digital version of the traditional paper-based Apostille certificate. This innovation streamlines the process of authenticating documents for international use, significantly reducing the time and effort required. For this option, the documentation must be first certified by a UK practising solicitor or notary public bearing a digital signature that must be an Advanced Electronic Signature (AES) or a Qualified Electronic Signature (QES). Simple digital signatures are not accepted for the e-Apostille legalisation. 

The FCDO can only issue an Apostille to an original foreign document IF the authenticity has been verified with the issuing institution/authority abroad by the notary public or solicitor. The UK practising solicitor or notary public when certifying the foreign original document must provide a separate cover sheet certificate attached to the underlying foreign document stating that the authenticity has been verified with the issuing authority abroad.

Also, a document which is received as an electronic/PDF document must be certified by the UK practising solicitor or notary public as a ‘true copy of the original electronic/PDF document’, which is the suggested wording given by the Hague Convention authorities. This is required to avoid rejection by the UK FCDO.

***It is important to note that original documents signed/stamped/sealed by UK public department officials can only be Apostilled IF the UK public official’s specimen signature or seal (as applicable to your document) is registered on the FCDO database.***

If the signature or seal is not registered, the FCDO will need to verify the official’s signature and/or seal with the relevant Public Department/Signatory (e.g. HMRC, ACRO Criminal Records Office,  GP Practice (Medical Practitioner), Court, DEFRA, Companies House, etc) in order to Apostille the document. The verification process may take anything between 1-5 working days to be completed, depending on how fast the relevant public department/signatory responds to the FCDO request. This process must be performed independently between the FCDO Legalisation Office and the relevant public department/officials.

In case of a signature query for GRO certificates (birth, marriage, death certificates and Certificate of No Impediment) in case the Registrar’s specimen signature is not registered on their database, the FCDO will send an email to the Register Office to verify the Registrar’s signature for certificates issued within 6 months only. If the certificate is older than 6 months, they will be unable to verify the signature and require a new certified copy to be obtained from the General Register Office (GRO) or the document holder to take action with the Register Officer to send the signature confirmation to the FCDO in order to be Apostilled. 

Upon completion by the FCDO, we can further process the documentation, if required, by the London and Arab Chambers of Commerce, Embassy or Consulate in the UK, as applicable, and return the legalised documentation to the final destination or have it available for collection from our London Office. Our usual practice is to provide a scanned copy of any legalised document along with the tracking details by e-mail before despatching the completed legalised documentation.
