Apostille Argentum UK - Legal Processing UK Ltd

Providing Apostille Legalisation Services For Over 15 Years

Legalisation (sometimes known as Attestation) is the process of authenticating documents for use in a different country. It is simply a means of telling an organisation, ministry or institution in a foreign country that the document in question is authentic and has been verified.

The process of legalising a document for use within another country who is also part of the Hague Convention is to have a government issued Apostille added which is then recognised and accepted by the other Hague countries. Other countries (normally those outside of the Hague Convention) may also require the document to be attested by their embassy – an additional service we have provided to our clients for over 15 years!

Since it is not everyday that you may need to legalise or apostille your documents, it may be a process that you are unfamiliar with. We make the process fast, simple and easy for our clients.

I can’t praise too highly the help that Argentum gave me in securing & delivering the legal document that I required for use overseas. I googled for a company that could help with legalization of a UK generated document for use abroad & up popped their name. If you have a similar requirement then contact Argentum you will not be disappointed. My document is currently in transit with DHL & is due for delivery to me here in the USA in less than a week! If I could give more stars I would.

I am very impressed with the service you have provided and will certainly keep you in mind if I need anything like this again in the future. I did look through many different companies before deciding on yours as there are indeed a lot of choices on the Gov.uk website. What made me decide to choose you was not only the more professional look of your website, which made you seem far more trustworthy, but you also had the most competitive price for the international courier return of the document with the apostille.

You have been absolutely FANTASTIC. I am impressed and grateful in equal measure.
