Why You Might Need an Apostille for Your Marriage Certificate
Many overseas legal procedures — including spouse visa petitions, dual nationality requests, and immigration filings — mandate an apostilled marriage certificate. Government agencies and foreign courts frequently demand this official validation to verify your marital status.
How to Get an Apostille for Your Marriage Certificate
To obtain an apostille, you must submit a certified copy of your marriage certificate along with a completed request form and the appropriate payment for processing. Request a certified copy from the vital records office in your state of marriage if you don’t have one.
Where Can I Apostille My Marriage Certificate?
Your marriage certificate must be apostilled by the Secretary of State in the jurisdiction that recorded it. Each state typically has its own authentication office, and we can help you navigate these differences, saving time and securing approval.


What If Your Document Is for a Non-Hague Country?
If you intend to use your marriage license in a country that doesn’t recognize apostilles, you’ll need to obtain a state-level authentication certificate first. The next step is to request federal authentication from the U.S. Department of State, followed by legalization from the embassy of the receiving country.
