What Is an Apostille and When Do You Need One?

If you’ve been asked to obtain an apostille for a document, you’re not alone—and you’re definitely not the first to feel confused by the process. Apostilles are commonly required for international matters, yet many people don’t encounter them until they urgently need one. Understanding what an apostille is and when it’s required can save time, stress, and costly delays.

What Is an Apostille?

An apostille is an official certification that verifies the authenticity of a public document so it can be recognized in another country. It confirms that the signature, seal, or stamp on a document is legitimate.

Apostilles are issued under the Hague Apostille Convention, an international treaty that simplifies document verification between member countries. Instead of going through multiple layers of authentication, a single apostille makes a document legally valid for use abroad.

An apostille does not verify the content of a document—it only authenticates the signature and authority of the issuing official.

When Do You Need an Apostille?

You typically need an apostille when a document issued in one country will be used in another country that is a member of the Hague Convention.

Common situations include:

• Studying or working abroad

• Dual citizenship or immigration applications

• Marriage or divorce overseas

• Buying or selling property in another country

• International business transactions

• Adoptions involving another country

If the destination country is not part of the Hague Convention, the document will usually require a different process called authentication, not an apostille.

Common Documents That Require an Apostille

Apostilles are often requested for both personal and business documents, including:

• Birth, marriage, and death certificates

• Divorce decrees

• Diplomas and academic transcripts

• Power of Attorney documents

• Background checks (such as FBI reports)

• Business documents (articles of incorporation, bylaws, resolutions)

• Adoption and guardianship paperwork

Some documents must be notarized first before they can receive an apostille, while others must be certified copies issued by a government agency.

How the Apostille Process Works

Although requirements vary slightly by state and document type, the general process includes:

1. Prepare the documentEnsure the document is properly notarized or certified, depending on its type.

2. Submit to the appropriate authorityIn most cases, this is the Secretary of State where the document was issued or notarized.

3. Apostille is issuedThe apostille is attached to the document, certifying it for international use.

Processing times can vary from same-day service to several weeks, depending on the state and whether expedited service is requested.

Common Apostille Mistakes to Avoid

• Submitting documents that are not properly notarized

• Using uncertified copies of vital records

• Apostilling a document in the wrong state

• Not confirming whether the destination country accepts apostilles

• Waiting until the last minute for time-sensitive travel or legal matters

These mistakes often cause delays or rejections, especially for international deadlines.

Do You Need a Notary for an Apostille?

Sometimes—but not always.

• Notarized documents (like Powers of Attorney or affidavits) usually require a notary before apostille processing.

• Vital records (birth, marriage, death certificates) generally must be certified copies issued by the state or county—not notarized copies.

Knowing the difference is critical to avoiding rejection.
