What is an Apostille?

An “apostille” is a form of authentication issued to documents for use in countries that participate in the Hague Convention of 1961.An Apostille is issued as an attachment and will validate the authenticity of your document to the foreign entity you are required to present your document to.

Who can get an Apostille?

When the United States joined the 1961 Hague Convention on October 15, 1987, they abolished the requirement of Legalization for Foreign Public Documents. Anyone seeking a U.S. document (such as Vital Records, FBI Reports, Articles of Organization or Incorporation) to present to one of the Hague Convention countries may request and obtain an apostille for that specific country, such as The United Kingdom. For State issued documents, the Office of the Secretary of State for each state is empowered to produce and provide the apostille attachment on documents for use internationally. For Federally issued documents, the US Department of State is tasked with the same. If you cannot obtain your apostille because you are not located near the Secretary of State that issued and/or notarized your document, send us your request by completing our Order FormWe’ll take care of your apostille needs with minimal effort on your end.

Obtaining an Apostille for use in The United Kingdom

Since joining the Hague Convention, documents to be presented to The United Kingdom have only required an apostilled issued by the Secretary of State or U.S. Department of State. All non-Federal documents such as vital records (birth, marriage, death), diplomas, transcripts, corporate documents, etc. must be apostilled by the Secretary of State in the State that the document was issued from or notarized in. Federal documents such as FBI Reports must be apostilled by the U.S. Department of State. The biggest challenge in obtaining an apostille are the unique document and Secretary of State or U.S. Department of State. requirements one must meet before the document is valid for apostille. This is why One Source Process, Inc. offers a commitment-free document review process that will ensure your documents meet all the requirements necessary for apostille.

Some of the most common documents that require translation are FBI Reports, FBI Background Checks, Birth Certificates, and Corporate Documents.

Professional and efficient – Having not been through the Apostille Service previously, we were guided and taught what we were doing by extremely professional and courteous individuals. We couldn’t be more pleased at the efficiency and the speed at which they were able to get the job done. The final product was accepted by the bank and the beneficiaries of the estate received their funds, everyone was happy. Thank you, One Source Process, Inc.
