Apostille Fees
Expedited authentication, notary & translation services
When presenting your paperwork to another country, you need a form of authentication that verifies the attached signatures and seals. There are two types of validation:
- Have your document apostilled
- Have your document legalized by the Embassy/Consulate
The Hague Convention of 1961 established a uniform process of confirming the authenticity of documents. Countries belonging to this convention accept papers that are apostilled, while non-member countries only accept legalized documents that are processed through the Embassy or Consulate.
Don’t worry if you are unsure which verification your destination country requires, we are able to apostille a document properly and return it quickly to you.
