Kentucky Apostille Guide — How to Authenticate Documents

Who issues Kentucky apostilles?

The Kentucky Secretary of State certifies the official signatures on public documents issued in Kentucky for use in a foreign country. Kentucky uses a single certificate for both apostilles (for countries in the 1961 Hague Apostille Convention) and authentications (for countries outside it, which may then require further legalization by that country's embassy or consulate). The office can only certify signatures it has on file, so the document must carry the right Kentucky signature before you submit it, and requests without the required signatures are rejected. Kentucky cannot certify federal documents such as FBI background checks, IRS records, or passports; those go to the U.S. Department of State, and documents from a U.S. District Court are handled by that court. Documents issued or notarized in another state go to that state's Secretary of State.

Getting the right signature on your document

This is the step that decides whether a Kentucky request is accepted. Vital records (birth, marriage, divorce, and single status certificates) must be certified copies from the Kentucky Office of Vital Statistics bearing the signature of the current State Registrar, so an older certified copy signed by a previous registrar may need to be reordered. County clerk records must be certified by a current County Clerk or Deputy Clerk. Circuit and District Court records signed by a Circuit Court Clerk must first go to the corresponding County Clerk to have the Circuit Clerk's signature certified. Paper documents notarized in Kentucky, including powers of attorney, affidavits, and school records like diplomas and transcripts, need two layers: a Kentucky notary's notarization and then a certification of that notary's signature by the County Clerk in the county where the notary is registered. Kentucky State Police criminal background checks must be specifically requested as notarized, then taken to the County Clerk for notary certification; background checks from the Administrative Office of the Courts lack the required signatures and cannot be apostilled directly. Documents electronically notarized by an authorized Kentucky online notary skip the county clerk step but must be submitted through the state's online e-Apostille portal.

Typical steps

1) Order or prepare the document: a current certified vital record from the Office of Vital Statistics, a certified county or court record, or a properly notarized document. 2) For paper notarizations and Circuit Clerk records, take the document to the right County Clerk for certification of the notary's or Circuit Clerk's signature. 3) Complete the Kentucky Request for Apostille or Authentication form, naming the destination country, the number of documents, the total fee, your contact details, the return address, and whether the document is county clerk certified or State Registrar certified. 4) Enclose the original document with the form and $5 per document, with checks payable to the Kentucky State Treasurer. 5) Mail the package to the address on the form (Office of the Secretary of State, Authentications and Apostilles, P.O. Box 718, Frankfort, KY 40602), walk it in to 1025 Capital Center Drive, Suite 201, Frankfort, or, for an eligible electronically notarized or e-certified PDF, submit it through the online portal and receive the e-Apostille by email.

Walk-in vs mail vs electronic vs courier

Walk-in is Kentucky's fastest path: bring the documents and fee to 1025 Capital Center Drive, Suite 201, Frankfort, Monday through Friday, 8:00 a.m. to 4:00 p.m., and requests are completed while you wait and handed back to you. Mail-in is the cheapest option for people outside the Frankfort area; the state says mailed requests are completed within 3 business days and returned by USPS First-Class Mail, and you can include a self-addressed prepaid FedEx, UPS, or USPS Priority label for faster, tracked return. Because the mailing address is a P.O. Box, private carriers like FedEx and UPS may not deliver to it, so use USPS for the outbound package or call the office to confirm a street address for courier delivery. Electronic filing returns a PDF e-Apostille by email and works only for documents notarized by an authorized Kentucky online notary or certified electronically by a County Clerk; it is not available for vital records. A courier or apostille service helps with multi-document batches, county clerk certifications in several counties, clients overseas, and non-Hague destinations that need embassy legalization afterward.

Fee and timeline estimates

Treat these as estimates and verify on the official Kentucky Secretary of State Apostilles and Authentications page and the current request form before you send originals. The state fee is $5 per document, one of the lowest in the country. Walk-in requests are typically finished during the same visit; mailed requests are completed within 3 business days of receipt, plus USPS transit both ways, so a full mail round trip commonly runs about one to two weeks. Budget separately for the certified vital record, any notary fee, any County Clerk certification fee, outbound tracked postage, a prepaid return label, courier fees, and embassy legalization for non-Hague countries. Fees, forms, and addresses can change, so confirm on sos.ky.gov.

When an expedited courier helps

Kentucky does not offer a paid rush tier because walk-in requests are already handled while you wait. If you cannot get to Frankfort yourself, a local courier can walk your documents in and send them back overnight, which is usually the quickest route for out-of-state and overseas clients. Couriers and apostille services are most useful when a document still needs a County Clerk certification first, when you have several documents from different counties, for consular or visa deadlines, overseas job or university start dates, international adoption files, and corporate packages headed to non-Hague countries that also need embassy legalization. Compare turnaround quotes, insurance for originals, and whether the $5 state fee is listed separately from the service fee.

FAQ

How much does a Kentucky apostille cost?

The Kentucky Secretary of State charges $5 per document. Certified copies, notary and County Clerk certification fees, shipping, and any courier or embassy fees are extra. Confirm the current fee on sos.ky.gov before you send payment.

How long does a Kentucky apostille take?

Walk-in requests in Frankfort are completed while you wait. Mailed requests are completed within 3 business days of receipt, plus mail time both ways. Including a prepaid FedEx, UPS, or USPS Priority return label speeds up the return trip.

Why was my Kentucky notarized document rejected?

Paper documents notarized in Kentucky need the notary's signature certified by the County Clerk in the county where the notary is registered before the Secretary of State can apostille them. Diplomas, transcripts, powers of attorney, and Kentucky State Police background checks all need this step.

Where do I send documents for a Kentucky apostille?

Mail the form, documents, and fee to Office of the Secretary of State, Authentications and Apostilles, P.O. Box 718, Frankfort, KY 40602, or walk in to 1025 Capital Center Drive, Suite 201, Frankfort. Older guides list 700 Capital Avenue, which is not the current apostille office.

Can Kentucky apostille an FBI background check or a birth certificate electronically?

No to both. FBI background checks go to the U.S. Department of State. Kentucky's electronic e-Apostille option is not available for vital records, so birth, marriage, and divorce certificates must be submitted on paper by mail or walk-in.

What is the difference between an apostille and an authentication in Kentucky?

Kentucky issues a single certificate for both. It works as an apostille for Hague Convention countries; non-Hague countries usually require an additional embassy or consulate legalization step after the Kentucky certificate.
