WHAT IS AN APOSTILLE?

An apostille is a certification issued by the California Secretary of State that authenticates the signature and seal on a public document for use in another country that is a member of the Hague Apostille Convention.

If the destination country is not a Hague member, the document must go through an authentication and legalization process instead.

KEY REASONS TO USE AN APOSTILLE SPECIALIST:

  • Expertise & Efficiency: We know the exact requirements of different countries and government agencies, preventing errors and delays.
  • Stress Reduction: We handle running around, form-filling, and submission, saving you significant time and frustration.
  • Risk Mitigation: We ensure documents are formatted correctly and meet legal standards, reducing the chance of rejection by foreign authorities.
  • Handles Various Documents: We specialize in personal (birth/marriage certs, diplomas), educational, and business (contracts, incorporation) documents.
  • Follow up on the entire process from beginning to end, making sure that your documents are ready within the specified timeframe.
