NY Apostille vs Authentication: Which Do You Need?
When a document needs to be used in another country, you need either an apostille or full authentication/legalization. The right process depends on which country will receive the document. Here is how to tell them apart and which applies to your situation.
The One Question That Decides Everything
Is the destination country a member of the Hague Apostille Convention?
YES - Hague Convention Member
Use an apostille from the NY Secretary of State. $10 fee. 2-4 weeks by mail or same/next day in person.
NO - Not a Hague Member
Use full authentication/legalization chain: NY DOS, then U.S. State Department, then destination country embassy. Weeks-long process.

Apostille Process in New York
If the destination country is a Hague Convention member, you need an apostille from the NY Secretary of State.
Have the document notarized by a commissioned NY notary (if it is a private document like a power of attorney or affidavit).
Take the notarized document to the County Clerk of the county where the notary is commissioned for authentication of the notary's signature.
Submit the county-authenticated document to the NY Secretary of State with the $10 apostille fee.
The DOS attaches the apostille. The document is now valid for use in any Hague Convention country.
Authentication/Legalization Process for Non-Hague Countries
If the destination country is NOT in the Hague Convention, the process has more steps and takes longer.
Have the document notarized by a commissioned NY notary.
NY County Clerk authenticates the notary's signature.
NY Secretary of State authenticates the County Clerk's signature.
U.S. State Department in Washington, D.C. authenticates the NY Secretary of State's signature.
The embassy or consulate of the destination country in the U.S. legalizes the document. This is the final step and makes it valid in that country.
