Document Authentication

G3's Document Legalization Team knows the requirements and procedures to ensure your important papers are accepted abroad.

International Document Expertise

G3 Global Services provides authentication services to US corporation, US citizens, and non-US citizens for all US-issued documents that will be used overseas. If you plan to use a US public or corporate document overseas, it must be legalized and certified by the local representation of that country (Consulate or Embassy) prior to use or it will not be valid. Each country has their own requirements for documentation, as it will depend on the type of document and how it will be used.
