Marriage Certificate Apostille for Mexico

By Frank MetayerUpdated October 22, 2026

Sooner or later, a Mexican office will ask a mixed U.S.–Mexican couple to prove their marriage. It might be a Registro Civil (Mexico's civil registry), a consulate handling a spouse's visa, or a notario público (a Mexican notary with far broader legal powers than a U.S. notary) closing on a house. In every one of those cases the U.S. marriage certificate has to arrive with an apostille, and almost always with a Spanish translation. An apostille is a certificate a U.S. state attaches so another country will accept the document as genuine.

Mexico has been part of the Hague Apostille Convention since August 14, 1995, so there is no embassy legalization step. One apostille from the right U.S. office does the job. The catch is that "the right office" depends on where you were married, and the translation rules depend on where in Mexico the document is going. This guide covers both, plus the one situation where none of it applies: a wedding that took place in Mexico.

Key takeaways

Start with a certified copy of the marriage certificate from the county or state that recorded the marriage. The decorative certificate handed to you at the ceremony is not the right document.
The apostille comes from the Secretary of State (or equivalent office) of the state where you married, not the state where you live now.
Most Mexican Registros Civiles want a Spanish translation by a perito traductor, a translator authorized by a Mexican state court. Rules differ from state to state, so ask the receiving office first.
If you married in Mexico, your acta de matrimonio is a Mexican record. It is apostilled by Mexican authorities, never by a U.S. office.
Recording a foreign marriage in Mexico has a timing rule: under Mexico's federal Civil Code (art. 161), if the marriage is transcribed within three months of the couple's arrival to live in Mexico, it takes effect from the wedding date. State civil codes can differ, so confirm current rules with the Registro Civil.

Which marriage certificate Mexico actually accepts

Most couples have two pieces of paper from their wedding. One is the decorative certificate the officiant hands you after the ceremony, often with a ribbon or a gold border. The other is the record the county keeps once the signed license is filed. Only the second one can be apostilled. A Secretary of State will not put an apostille on a souvenir certificate, and a Mexican office would not accept it if one did.

What you need is a certified copy issued by the government office that holds the record. In most states that is the county clerk or county recorder where the license was filed. Some states also issue certified copies through the state vital records office. A few states only apostille copies signed by particular officials, or copies issued within a recent window, so it pays to order a fresh certified copy rather than digging out one from years ago. A plain photocopy, even a notarized one, is not a substitute for a certified copy of a vital record.

Check the names while you are at it. If either spouse has since changed a name, or a name is spelled differently on a passport or a Mexican birth record, flag it now. Name mismatches are one of the most common reasons a Registro Civil sends paperwork back.

Who issues the apostille: the state where you married

A U.S. marriage certificate is a state-level record, so the apostille comes from the Secretary of State of the state that issued it. The U.S. Department of State does not apostille marriage certificates; it handles federal documents such as FBI background checks. If you were married in Nevada and now live in California, the apostille comes from Nevada. Sending the certificate to your home state's office is a frequent and avoidable mistake.

Some states add a step before the Secretary of State. In New York, for example, many county-issued records first need a certification from the county clerk. A handful of states route apostilles through a Lieutenant Governor or another office instead of a Secretary of State. We handle these routing differences every week. You can read more about the U.S. side of this process on our marriage certificate apostille page.

Why you need it: the most common uses in Mexico

Recording the marriage in Mexico. When a Mexican citizen marries abroad, the marriage is valid where it took place. To get it onto the Mexican civil record, it is transcribed at a Registro Civil. This is often called inscripción or inserción de matrimonio celebrado en el extranjero. Mexico's embassies describe it as a Registro Civil function. Each state sets its own list of requirements, so call the office in the municipality where you plan to live.

Timing matters too. Under the federal Civil Code, if the couple transcribes the marriage within three months of arriving to live in Mexico, the civil effects date back to the wedding. If you register later, they start from the registration date. State civil codes may set their own rules.

Spouse visas and residency. A foreign spouse of a Mexican citizen or of a Mexican resident can apply for residency on family-unity grounds, and the marriage certificate is the core evidence. Mexican consulates and the National Migration Institute (INM) generally ask for it apostilled and translated. Requirements for these applications change, so confirm the document list with the consulate or INM office handling your case.

Children and dual nationality. When a couple registers a U.S.-born child as a Mexican national, the child's U.S. birth certificate is the main document (see our birth certificate apostille for Mexico guide for when it needs an apostille). Some Registros Civiles also ask for the parents' marriage certificate, especially when both parents are listed or when surnames need to be established. Have it apostilled at the same time so you are not starting over mid-process.

Property, inheritance, and banking. Notarios públicos may ask for an apostilled marriage certificate when a married couple buys property, sets up a fideicomiso, or handles an estate, because a spouse's rights can depend on the marriage regime. Banks sometimes ask as well when opening joint accounts.

The Spanish translation and the perito traductor

Many Mexican offices will not accept a document in English, and they are specific about who translates it. The usual requirement is a perito traductor, a translator authorized by the Superior Court of Justice of a Mexican state (or, for federal matters, by a federal court). Several Registros Civiles also want the apostille itself translated, not only the certificate.

This is where the rules vary most. Some offices accept a perito from any Mexican state; others want one registered in their own state. Some accept a translation done before you travel; others expect it to be done in Mexico. A general certified translation from a U.S. translator may be fine for one office and rejected by another. Before you order a translation, ask the receiving office exactly what it accepts and write down the answer.

We coordinate certified translation as part of a Mexico order, including arranging a translation by an authorized perito when the receiving office requires one. We are not peritos ourselves, and we will tell you plainly when the receiving office's rules point you to a translator in Mexico. The order that works almost everywhere is apostille first, then translation, so the translation covers the apostille too.

If you married in Mexico, this process does not apply

A wedding held in Mexico, in Cancún, Puerto Vallarta, Los Cabos, or anywhere else, is recorded by a Mexican Registro Civil on a Mexican acta de matrimonio. That is a Mexican public document. A U.S. Secretary of State cannot apostille it, because the apostille certifies the signature of the official who issued the document, and that official is Mexican.

If you need a Mexico wedding recognized in the United States or another country, you order a certified copy of the acta and have it apostilled by the government of the Mexican state that issued it. Mexico's official apostille information on gob.mx explains which authority handles which documents. Then you arrange an English translation for the U.S. office that asked for it. Many U.S. agencies accept a certified translation from a U.S. translator.

Where we do help Mexico-wedding couples is on the front end: the U.S. documents a Mexican Registro Civil asks for before the ceremony, usually birth certificates, and sometimes a divorce decree or a single-status affidavit. Those are U.S. documents and are apostilled here.

Why marriage certificates get rejected in Mexico

Here is what we see bounce back most often. The certificate is the ceremonial or souvenir version instead of a certified copy. The copy is uncertified, or a photocopy of a certified copy. The apostille came from the wrong state because the couple used their current home state instead of the state where they married. The document arrived in English with no translation, or with a translation from someone the office does not recognize. Or the names on the marriage certificate do not match the spouse's passport or Mexican records.

A last one catches people who plan ahead: some offices want a certified copy issued recently, often within the last several months. If your apostilled certificate has been sitting in a drawer for a few years, ask whether it is still acceptable before you book travel around it. The apostille itself does not expire, but the receiving office decides how recent the underlying copy must be.

Frequently asked questions

Which state apostilles my marriage certificate for Mexico?+

The state where you were married, not the state where you live now. A U.S. marriage certificate is a state record, so it is apostilled by that state's Secretary of State (or equivalent office). The U.S. Department of State does not apostille marriage certificates.

Can I apostille the certificate we signed at our wedding?+

No. The decorative certificate from the ceremony cannot be apostilled. You need a certified copy issued by the county clerk or recorder, or by the state vital records office, that holds the official record. A recently issued copy is safest, because some Mexican offices set a recency limit.

Do I need a Spanish translation by a perito traductor?+

Usually, yes. Most Mexican Registros Civiles want a Spanish translation by a perito traductor authorized by a Mexican state court, and many want the apostille translated too. Some offices accept a perito from any state or a translation done in the U.S.; others do not. As of 2026, confirm the rule with the receiving office before ordering the translation. Apostille first, then translate.

We got married in Mexico. Can a U.S. office apostille our acta de matrimonio?+

No. A marriage recorded in Mexico produces a Mexican acta de matrimonio, which is apostilled by the government of the Mexican state that issued it. U.S. authorities can only apostille U.S. documents.

Is there a deadline to register a U.S. marriage in Mexico?+

Under article 161 of Mexico's federal Civil Code, if the couple transcribes the foreign marriage at the Registro Civil within three months of arriving to live in Mexico, it takes effect from the wedding date. If you register later, it takes effect from the registration date. State civil codes can differ, and each state sets its own document list, so confirm with the Registro Civil where you will live.

How much does a marriage certificate apostille for Mexico cost?+

It depends on the document, the issuing authority, and how fast you need it. You see our flat price per document before you order — with no hidden fees.
