Do Birth and Marriage Certificates Need Apostilles for a Spain Residency Application?

Many applicants for a Spain visa or residency focus on the FBI report and forget about another document type that shows up just as often in the same file: birth and marriage certificates. These civil records don't follow the same apostille route as the FBI report, and knowing the difference keeps you from sending the right document to the wrong office.
Birth and marriage certificates issued in the United States are apostilled by the Secretary of State of the state where the birth or marriage took place, not by the federal government. They're needed when a procedure requires proof of identity, parentage, or a family relationship, for example when including a spouse or dependent children in an application. Always confirm with your consulate whether your specific visa category requires these certificates, and whether they also need an official Spanish translation.
