One Source Process Makes Obtaining an Apostille Simple

An apostille is a form attached to your US document that verifies the authenticity of the seals and signatures, and are commonly used when submitting documents to other countries.

Apostilling documents can be a complex process. In most cases, you must obtain an original or certified copy of the document you are required to apostille. Once received, the document will have to be submitted to the issuing office of authentications, such as the Secretary of State, the US Department of State in Washington, DC, or the embassy or consulate.

The biggest challenge in the apostille authentication process is the unique requirements of each document one must meet before the paperwork is valid for apostille. This is why One Source Process offers a commitment-free document review service that will ensure your documents meet all the requirements necessary for apostille or embassy legalization.

Our comprehensive document apostille services allow us to prepare, file, and obtain the apostille for every state on your behalf – in the most convenient and professional manner. We can sometimes provide same-day apostille service for personal and business documents. But please keep in mind that federal documents through the US Department of State take more time. To get started: complete our Order Form.

  1. Fill out the Order Form. This is where you tell us what documents require authentication and for what country.
  2. Upload or mail us the original or certified copy of each document. We will review all paperwork for FREE and notify you of any missing or wrong information.
  3. We will send you a payment invoice and timeline for completion. You do not pay until the documents are error-free and ready to go.

That is all you have to do. We will take it from here. We have worked with every state and just about every country to obtain the apostille or embassy legalization. Let us deal with the governmental red tape. We know what offices to contact in order to get the apostille process done quickly.

Common Mistakes We Watch For

It’s easy to make a mistake when gathering the required documents. And that is why we offer a free review of all paperwork before we submit the apostille application. Mistakes can be made by the notary signing the papers, the county clerk’s office, or you. But don’t worry; we double-check everything first.

Some common mistakes we have found are:

  • The notary’s license expired
  • Papers not notarized properly
  • The county clerk’s document is expired
  • Specific states require the Triple Seal page, which is sometimes forgotten
  • You mistakenly had your birth certificate notarized when it should be a certified copy instead.
  • Not all the correct boxes were checked, or a signature was missed on the application form.

Even the smallest error can cause your application process to be delayed or rejected. To prevent this, we carefully review each document.

Let’s Work Together

We understand this can be confusing. But don’t worry, we have apostilled and legalized just about every type of document – so this is kind of fun for us. We know exactly the process each document must follow to be authenticated.

We know the necessary steps for state and federal documents and can quickly authenticate them. We offer certified translation services, dedicated agents, and a 100% satisfaction guarantee.

When you’re ready… let’s work together.

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.
