You are marrying someone abroad. You are enrolling your child in a school in another country. You are inheriting property in your grandmother's village. You are being asked for an apostille, and you have no idea what one is.
Here's the short version, and then the step-by-step for anyone in New York State who needs to get one done.
What Is an Apostille?
An apostille is an internationally recognized certification that authenticates the origin of a public document, so that it can be accepted in another country. It was created by the 1961 Hague Apostille Convention, which now has more than 120 member nations.
In practice, an apostille is a one-page attachment from the New York Department of State that says: "yes, this signature and seal are genuine, and yes, the person who signed this had the authority to do so." Foreign governments trust that certification because they've agreed to trust it under the treaty.
If your destination country is not a Hague signatory (a small but important list including Canada, the UAE, China's mainland, and some others), you'll need "legalization" instead, which is a different multi-step process. Check the destination requirements before you start.
Documents That Commonly Need an Apostille
- Birth certificates, marriage certificates, death certificates
- Diplomas, academic transcripts, and school records
- Power of attorney documents for foreign real estate or business
- Articles of incorporation and corporate resolutions
- FBI background checks (for teaching, adoption, or foreign residency)
- Adoption paperwork
- Single-status affidavits for foreign marriages
The New York Process, Step by Step
Step 1: Confirm the Document Is Eligible
New York apostilles are only issued for documents that were signed or issued in New York State. A birth certificate from Ohio needs to be apostilled by Ohio, not New York, even if you live in Nassau County.
Step 2: Get the Document in the Correct Form
Different document types follow different paths:
- Vital records (birth, marriage, death) issued by New York City must first be certified by the NYC Department of Health and Mental Hygiene. Records from the rest of the state come from the New York State Department of Health.
- Notarized documents (affidavits, powers of attorney, single-status statements) need to be signed in the presence of a New York notary first.
- Diplomas and transcripts often need to be notarized by a school registrar, then routed through the county clerk before the DOS.
- FBI background checks follow a different national path and generally require a U.S. Department of State apostille, not a New York one.
Step 3: County Clerk Certification (When Required)
For notarized documents, the notary's commission must first be verified by the county clerk where the notary is commissioned. This is called the "authentication of the notary's signature" and it's a required step before the DOS will process the apostille. Skipping it is the number one reason apostille requests come back rejected.
Step 4: New York Department of State
Once the document has its underlying certification (from the county clerk or the vital records office), it goes to the DOS Apostille Office. You can submit in person or by mail. The DOS issues the apostille, which is a single-page certificate attached to your original document.
Step 5: Delivery
You get the original document back with the apostille attached. That's what you ship or hand-carry to the destination country.
How Long Does It Take?
Standard processing time in New York is usually two to three weeks, though it varies with volume. Expedited service is available for urgent situations at an additional fee. Government processing times can change without notice, especially around holidays and the summer.
An apostille is a passport for paper. It lets your document cross a border.
Common Mistakes That Cause Rejections
- Sending a photocopy when the original is required
- Missing the county clerk authentication step for notarized documents
- Trying to apostille an out-of-state document in New York
- Using an expired or improperly formed notarial certificate
- Submitting a vital record that hasn't been certified by the issuing agency

Frequently Asked Questions
How long does an apostille take in New York?
Standard apostille processing in New York usually takes about two to three weeks, though it varies with volume at the Department of State. Expedited service is available for urgent situations at an additional fee.
Can I apostille an out-of-state document in New York?
No. New York can only apostille documents that were signed or issued in New York State. A birth certificate from another state must be apostilled by that state, even if you currently live in New York.
What documents commonly need an apostille?
Common examples include birth, marriage, and death certificates, diplomas and transcripts, powers of attorney for foreign use, articles of incorporation, background checks, and adoption paperwork intended for use in another country.
Do notarized documents need an extra step before the apostille?
Yes. For notarized documents, the notary's signature must first be authenticated by the county clerk where the notary is commissioned before the Department of State will issue the apostille. Skipping this step is the most common cause of rejection.
