How to Apostille Documents for Use in Spain (California Guide)

If you need to use a U.S. document in Spain, it must be authenticated with an apostille. Because both the United States and Spain are members of the Hague Convention, an apostille issued by the California Secretary of State verifies the authenticity of signatures and seals so your documents are legally accepted in Spain.

Whether your paperwork is for citizenship, marriage, education, property matters, or business transactions, this guide explains how the apostille process works in California — and how I can help ensure everything is done correctly the first time.

• Missing required California notarial wording
