Washington Apostille Service

When you need to apostille a document for traveling abroad, you can either work on your own to obtain one, or work with us and let us handle the red tape for you.

An apostille is the certification of the signatures and seals on a document. Papers can either be apostilled or legalized, depending on your destination country.

Countries that are members of the Hague Convention of 1961 established a uniform acceptance of authenticity called an apostille. All non-member countries must have documents authenticated through the embassy or consulate.

But don’t worry if you are unsure if your papers are required to be apostilled or legalized; we have worked with the officials in Washington state and just about every country – we can properly authenticate your documents.

Obtaining Your Washington State Apostille

At One Source Process, we specialize in the apostille or embassy legalization of your documents – including personal and business papers. From birth certificates to company bylaws, we will have them properly apostilled and quickly returned to you.

While we are centrally located in Washington, DC, to offer you a smooth apostille process, we work with all states and countries to ensure efficient and professional service.

Our customer service will exceed your expectations; we guarantee it. We are dedicated to 100% customer satisfaction.

Understanding the Authentication Process

The first step of authenticating a document is to determine if your documents need state authentication or if you must work with the federal offices to receive the apostille or legalization.

Examples of State Documents:

  • Birth and death certificates
  • School records
  • Business hiring records

Examples of Federal Documents:

  • Passport
  • FBI background check
  • Social Security benefits letter

Once you know which document you’re working with, you can contact the correct offices.

  • For state documents, you must contact the Secretary of State
  • For federal documents, you must contact the US Department of State in Washington, DC
  • If the destination country is not a member of the Hague Convention of 1961, you must also work with the embassy or consulate to authenticate the paperwork.

It can be confusing to obtain an apostille or embassy legalization. But when working with us, authenticating your paperwork is easy. If you are unsure what you need, please contact us, and we can point you in the right direction.
