Where to Obtain an Apostille for a Vital Record
If you need a vital record received from the State Vital Records Office for an international purpose, such as to apply for dual citizenship or to marry in a foreign jurisdiction, you may need to have the record certified with an Apostille by the CT Office of the Secretary of State.  In Connecticut, the Secretary of State is responsible for issuing certifications by Apostille.
An Apostille is a special form of certificate authentication prepared under the terms of an international treaty known as "The Hague Convention Abolishing the Requirement of Legalization for Foreign Public Documents." The Apostille simplifies the authentication process by exempting documents certified with the Apostille at the state level from any additional certification by a higher authority, such as at the US Department of State or consulate.
For questions and fees related to obtaining an Apostille for a vital record, please contact the CT Office of the Secretary of State at www.ct.gov/sots/ or:
