Important Key Points

Notarization

Many documents require notarization before they can be apostilled.

Certified Copies

Government-issued documents (birth, death, marriage certificates) must be certified copies. Notarization is not required.

Federal Documents

Certain federal documents (FBI background checks, federal court documents) require authentication from the U.S. Department of State, not an apostille.

Document Requirements

Ensure your document is properly notarized or certified by the issuing authority for a smooth apostille/authentication process.
