Connecticut documents used abroad — for adoption, marriage, business, education, immigration, or legal proceedings — typically require official authentication before a foreign authority will accept them. The Connecticut Secretary of State issues apostilles for eligible state documents.
Nations that participate in the 1961 Hague Apostille Convention recognize an apostille as adequate verification of a document’s authenticity. Connecticut authentication for non-Hague countries follows a different legalization process, often involving additional federal and embassy or consular steps.
