Apostille vs. Notarization in Michigan

What notarization does

A Michigan notary identifies the individual using personal knowledge or satisfactory evidence, confirms the signer is participating willingly, performs the requested eligible notarial act, and completes the notarial certificate. Depending on the act, the signer may acknowledge an earlier signature or sign in the notary’s presence and take an oath or affirmation.

Notarization does not prove that every statement in the document is true. It does not make the document legal, select the correct form, or tell the signer which notarial act to use. The document recipient or a qualified adviser must supply those instructions.

What an apostille or authentication does

An apostille is a state-issued certificate used for eligible public documents going to a country participating in the Hague Apostille Convention. When the destination does not use that convention, a different certificate-of-authority or legalization path may apply.

For Michigan documents, the Office of the Great Seal reviews the public signature or seal in the authentication chain. That state review is separate from the notary’s interaction with a signer. Signature Line Services does not perform the state’s review and does not issue the apostille.

Why the steps may happen in sequence

Some private documents first need an eligible Michigan notarization. The completed notarial certificate then provides the commissioned notary signature and details the state can evaluate in the authentication process. Other documents—such as certain certified public records—use an authorized official’s signature and may not require an added notarization.

The sequence should come from the document type and current instructions, not from a blanket rule. Adding an unnecessary notarization can create the wrong document path, while skipping a required signature or certificate can delay state review.

Recipient and destination instructions come first

Ask the foreign recipient or requesting organization:

• exactly which document it will accept;
• whether it needs an original, certified copy, or signed statement;
• whether notarization is required before authentication;
• which country or jurisdiction will receive the document; and
• whether translation or later legalization steps apply.

Then compare those instructions with the Michigan Department of State’s current authentication guidance. If the instructions are unclear or affect legal rights, ask the recipient, issuing agency, or qualified legal counsel to clarify them.

Choosing the right Signature Line Services path

Use General Notary when a prepared document already identifies an eligible notarial act and the immediate need is the signer-and-certificate step. Use Apostille Services when the request involves preparing or coordinating an eligible Michigan document for international authentication.

One request can involve both services, but they remain separate steps with separate decision-makers. Private assistance can help organize the workflow; it cannot guarantee state issuance or foreign acceptance.
