Instructions

1. Contact the office of the secretary of state for your state of residence. The easiest way to do this is to visit your state's website (find yours here).
2. Visit the "notary public services" section at the website. Find the pages that explain the "authentication" or "apostilling" services. This may vary by state. If you can't find it, use the search box and type in "apostille."
3. Gather together your documents that need to be apostilled, as well as the money needed to pay for it. While each state is different, the price to apostille each document will range from $8 to $100.
4. Decide if you are going to mail the documents or take them in person to the state secretary's office (usually located in the state capital city). If you mail them, you must include your name and address, form of payment (a personal check will work) and the location to which you want them mailed, as well as a postage-paid envelope for mailing the apostilled document. Many state websites will have an apostille request form you can download and fill out to mail with your documents.
5. Follow up to make sure your apostilled documents reached their intended destination. It usually takes around three days for most states to process, apostille and mail a document. If you are taking it in person to be apostilled, they will do it for you while you wait, and then you can mail it yourself.
