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.

Testimonials from real clients
I highly recommend One Source Process for all of your document legalization needs. I will recommend them to my colleagues, friends, and incoming employees for overseas employment. They tackled two complex problems for me with ease. They communicated well and addressed all my concerns in a prompt manner through email and phone calls. If you ever need document legalization services, call no one else, I won’t.
We have used a few different process servers and no one has provided the level of customer service that One Source Process has. They are very reliable and they communicate every step of the way. Alex and Brandon have been a huge help and they always take their time to understand our needs. We look forward to working with One Source Process for a long time
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.
