Notary & Document Authentication (Apostille)

Getting documents properly signed, notarized and authenticated for use in the US and abroad.

Overview

What this involves

Documents signed in one country often need to be formally authenticated before they are accepted in another. Countries that are party to the Hague Apostille Convention accept an apostille; others require a longer chain of legalization. Getting it wrong can cause costly delays.

We help individuals and businesses prepare, sign and authenticate documents for use abroad and in the United States: powers of attorney, affidavits, corporate documents and more. We guide you through each step, which for many New York documents runs through the county clerk and the New York Department of State.

FAQs

Frequently asked questions

What is an apostille?

An apostille is a certificate that authenticates a public document for use in countries that are party to the Hague Apostille Convention, replacing the longer legalization process.

Where do New York documents get apostilled?

Many New York public documents are apostilled by the New York Department of State, often after certification by the county clerk. Federal documents follow a different route. We confirm the right path for your document.

What if the destination country does not accept apostilles?

Then the document usually needs legalization through that country's consulate. We explain the steps.
