Certificate attestation is the process of verifying the authenticity of official documents, such as educational certificates, birth certificates, marriage certificates, and other legal documents. This verification is done by relevant authorities or government departments to ensure the legitimacy of the document for use in foreign countries or for official purposes.

Attestation is typically required when individuals need to use their certificates for purposes like immigration, higher education, employment, or legal matters in a foreign country. The attested certificate is recognized internationally, confirming its authenticity and validity.
