What Is a Marriage Certificate Apostille?

The Hague Apostille Convention eliminated the old multi-step embassy legalization process that existed before 1961. Before apostilles, getting an American document accepted overseas involved multiple rounds of authentication at different government levels followed by embassy stamps. The Convention simplified this into a single certificate issued by one designated authority. For Marriage Certificates issued in Illinois, that authority is the Illinois Secretary of State in Springfield.

Marriage Certificates are one of the most common apostille categories nationally. This is because Marriage Certificates come up in many international processes including visa applications, residency permits, citizenship documentation, employment verification, and foreign legal proceedings. If you are in Illinois, the Illinois Secretary of State in Springfield is the correct office for Marriage Certificate apostilles.

An apostille is a standardized Hague certification established by the Hague Convention of 1961. Unlike standard document certification, an apostille is recognized internationally — meaning your Marriage Certificate is valid for submission to foreign embassies, government offices, and employers. If you are in Illinois, Illinois, obtaining this certification requires working with the Illinois Secretary of State.

Illinois: State vs Federal Authority

For state-issued Marriage Certificates, the apostille is only available from the Illinois Secretary of State's office. Before submission, the document must carry an original official seal or notarization. The Illinois Secretary of State reviews the document's seals and signatures and attaches the apostille typically in 1 to 3 weeks.

One of the most costly apostille mistakes is routing documents to the wrong office. If you send a state Marriage Certificate to Washington D.C., it will be rejected and returned. In reverse, mailing a federal document to a state Secretary of State office will also come back unprocessed. Either way, the round-trip postal time adds 2 to 4 weeks to your timeline.

When timelines are tight, expedited apostille service may be available. Some state offices provide same-day service for in-person deliveries. Our team takes advantage of in-person processing by walking documents in, getting you the fastest possible turnaround from Illinois.

Why Local Offices Cannot Help

People across Illinois mistakenly believe they can get an apostille at a local notary office in Illinois. This assumption is wrong. A notary public can only witness signatures and verify identity. They have no authority to issue an apostille certificate — only the Illinois Secretary of State can do this.

Something else to consider is that the receiving country check whether the apostille was issued by the proper office. If the apostille comes from an unauthorized office, the foreign embassy or government office will reject it. This may delay your entire application even if everything else in your application is correct.

It is also worth knowing, local government offices in Illinois are equally unable to apostille documents. Even a trip to the Illinois city hall, county courthouse, or register of deeds would not produce an apostille. The sole authority in Illinois authorized to issue apostilles for state documents is the Illinois Secretary of State.

The Illinois Apostille Authority

There is sometimes a step before apostille submission: it may need to be notarized or certified first. Diplomas, powers of attorney, and affidavits typically require notarization as a first step. We advises you on any pre-apostille requirements before submitting to the Illinois Secretary of State so your submission is accepted on the first attempt.

In IL, the correct office is the Illinois Secretary of State in Springfield.

What to Include With Your Submission

Before sending your document to the Illinois Secretary of State, confirm you are sending: your original Marriage Certificate or an official certified copy, any required notarization, a completed submission form if required, payment for the state fee of $2, and a prepaid return envelope or shipping label. Leaving out any item will result in your documents being returned unprocessed.

Some Illinois residents ask whether a cover letter is needed with their apostille submission.

Common Apostille Mistakes to Avoid

Failing to provide a prepaid return label is a simple but common mistake. The Illinois Secretary of State in Springfield will not return your document without a prepaid return method. Without a return label, your completed apostille could wait weeks to reach you. Our service includes return shipping — you never have to worry about return logistics.

The number one mistake is sending your document to the wrong government authority. Illinois residents sometimes send federal records to their state Secretary of State. In both cases, the office will reject the submission and return the document unprocessed. This mistake costs weeks — the time lost in transit to and from the wrong authority — before you can resubmit correctly.

Sending original documents through the US Postal Service without a tracking number is a significant risk. Uninsured postal shipments are vulnerable to loss with no recourse. Original government-issued documents are sometimes time-consuming and costly to replace. We ship all documents via FedEx for complete end-to-end protection.
