Which of the following documents are issued by the Illinois Secretary of State?

The Illinois Secretary of State issues both apostilles and certificates of authority. An apostille is a certificate that authenticates the origin of a public document and is used for documents that will be recognized in foreign countries that are part of the Hague Convention. This process verifies the legitimacy of a document and is important for international legal procedures.

On the other hand, a certificate of authority is a document that allows foreign entities to transact business in Illinois. It certifies that a business is legally registered in its home state and is allowed to operate in Illinois.

Notarial acts, which include actions taken by a notary public such as witnessing signatures and administering oaths, are not issued by the Secretary of State but are rather performed by individual notaries. Hence, the correct answer encompasses both types of documents that are officially issued by the Illinois Secretary of State, confirming their authority in handling these matters.
