An apostille is a form of certification set out in the 1961 Hague Convention, to which the United States is a subscriber. It is a form of numbered fields, which allow data to be understood by the receiving country regardless of the language used by the issuing country.
The Hague Convention defines the purpose of an apostille as to “abolish the requirement of diplomatic or consular legalisation for foreign public documents.”
Here is a listing of countries that follow the Hague Legalization Convention.
An apostille (or authentication) is used as transmittal on public documents executed in one subscribing country which are being sent to another subscribing country. The Hague Convention defines public documents as:
A few examples of these public documents would include:
School documents must be signed by a school official and notarized.
It is important to note that the Idaho Secretary of State can authenticate only documents issued by Idaho officials or notarized by Idaho Notaries.
Each subscribing nation designates which authorities may issue apostilles for their jurisdiction. The United States has appointed the Secretary of State (or their counterpart) in each state as said authority. The Secretary of State of Idaho has expanded this authority in Idaho to include his Deputy Secretaries of State and the Secretary of State's Notary Clerks.
