Notary & Document Authentication (Apostille)
Preparing and authenticating documents so that they are accepted in another country.
Overview
What this involves
A document signed in New York is not automatically accepted abroad. Foreign authorities usually require it to be notarized and then authenticated, either by an apostille or by a longer legalization chain, depending on the country.
KMC Justice helps clients prepare documents and complete the steps needed for them to be recognized overseas.

FAQs
Frequently asked questions
What is an apostille?
It is a certificate issued under an international convention that confirms a public document's origin, so that other member countries will accept it.
Is an apostille always enough?
No. Countries outside the convention require a longer process involving their embassy or consulate. We tell you which applies.
Can the document be signed before I travel?
Often yes, but the form and timing depend on the destination country's requirements. Ask us before signing.
