Connecticut Document Authentication

Connecticut Apostille Services

Connecticut documents intended for use abroad may require an apostille or authentication before they can be accepted by a foreign authority.

The Connecticut Secretary of the State authenticates qualifying Connecticut public officials, notaries, court clerks, vital-record registrars, and other eligible signatures.

Connecticut Apostille Formats

Paper Apostille or e-Apostille?

Connecticut now offers both traditional paper apostilles and electronic apostilles for certain eligible documents. The appropriate format depends on the document itself and the receiving authority.

Traditional Processing

Paper Apostille

A physical apostille is attached to the qualifying original or certified document. Paper processing remains required for certain record types, including Connecticut vital records.

Birth, death, marriage, and adoption certificates currently require the traditional paper apostille process.
Electronic Option

Connecticut e-Apostille

Certain eligible Connecticut public documents may receive a secure electronic apostille issued digitally by the Secretary of the State and verified through Connecticut’s online registry.

Not every document qualifies, and the receiving authority should accept electronic apostilles before this route is selected.

Preparing a Connecticut Document for Authentication

Connecticut authentication depends on the document type, issuing authority, and signature being certified. We review these elements before submission to determine the appropriate process.

01 / Record

Use an Original or Certified Copy

Connecticut requires an eligible original document or certified copy rather than an ordinary unverified photocopy.

02 / Signature

Connecticut Official or Notary

The document must generally be notarized by a Connecticut notary public or certified by an eligible Connecticut public official whose signature can be authenticated.

03 / Certification

Original Signature or Seal

Connecticut requires the qualifying notarization or certification to contain the original signature and/or seal required for authentication.

04 / Destination

Identify Where the Document Will Be Used

The destination country determines the authentication treatment and whether the receiving authority will accept the document in its issued format.

Connecticut also applies a 10-year rule.

Current Secretary of the State guidance states that documents submitted for authentication must generally have been notarized or certified within the last 10 years. Older records may require an updated certified copy or renewed certification before processing.

Frequently Asked Questions

Connecticut Apostille FAQs

Who issues apostilles in Connecticut? +
Apostilles and authentications for eligible Connecticut documents are issued by the Office of the Connecticut Secretary of the State.
Does Connecticut offer electronic apostilles? +
Yes. Connecticut began issuing e-Apostilles for certain eligible documents in 2026. Not every document qualifies, and the receiving authority should confirm that it accepts an electronic apostille.
Can a Connecticut birth or marriage certificate receive an e-Apostille? +
No. Connecticut currently excludes vital records from its e-Apostille service. Birth, death, marriage, and adoption certificates continue to require a traditional paper apostille.
Can Connecticut authenticate a document older than 10 years? +
Connecticut's current guidance generally requires the qualifying notarization or certification to have occurred within the last 10 years. An older document may therefore need an updated certified copy or new qualifying certification before submission.
Can Connecticut apostille a photocopy? +
Certain copies may qualify when accompanied by a sworn written statement affirming that the copy is true and accurate and the statement is signed before a Connecticut notary. Public and vital records should instead be obtained as certified copies from the proper government custodian.
Can Connecticut authenticate a document notarized in New York or another state? +
No. Connecticut does not authenticate documents signed by an out-of-state notary. A document notarized in another state generally follows that state's authentication process.
