The Surrogacy Legal Process in Mexico City

How intended parents are recognised as the legal parents of their child, step by step, with Rafael Guzmán Romero and the legal team of the surrogacy program led by Dr. Castillo Peláez.

How does the surrogacy legal process work in Mexico City?

Mexico City does not have a dedicated surrogacy law, so intended parents are recognised through a court-supervised process rather than an automatic registration. The route is called voluntary jurisdiction (jurisdicción voluntaria). It is a non-contentious proceeding before a family judge, used when there is a surrogacy agreement signed before a notary and no dispute between the parties. The judge verifies how the agreement was carried out and that the surrogate's rights were respected, and the judge's resolution then serves as full proof for the Civil Registry to issue the birth certificate in the intended parents' names.

The Supreme Court of Mexico confirmed this route in February 2026, and in September 2026 it became binding jurisprudence (P./J. 181/2026) that every court must follow. The legal basis is what Mexican law calls procreational will, the intention to become a parent, rather than the act of giving birth. The surrogate is never recorded as the mother, both partners in a couple can be named, and no adoption is required.

Key facts

  • Parentage is established through voluntary jurisdiction, now binding jurisprudence of the Supreme Court for Mexico City.
  • Intended parents are named directly on the birth certificate. No adoption is needed.
  • The surrogate is never recorded as the mother.
  • Your baby receives a Mexican birth certificate and Mexican passport, then the passport of your home country.
  • All legal fees are included in the program price and paid phase by phase.

The legal basis for surrogacy in Mexico City

Two Supreme Court decisions shape how this works. In 2021, the Court ruled that surrogacy is a constitutionally protected medical procedure and that no one can be excluded on the basis of nationality, marital status, or sexual orientation. It also established that legal parentage flows from procreational will rather than from birth.

For years after that, courts in Mexico City disagreed on the procedure. Some judges accepted voluntary jurisdiction to register the intended parents, and others said it was not the right route, which left families depending on which court they landed in. On February 3, 2026, the full Supreme Court settled that disagreement (contradicción de criterios 159/2025). It ruled that voluntary jurisdiction is the proper route to verify the facts arising from a surrogacy agreement signed before a notary, and that the judge's resolution is full proof to issue the birth certificate under article 73 of the Mexico City Civil Registry Regulations.

That criterion was published on September 11, 2026 as jurisprudence P./J. 181/2026, and it has been mandatory for all courts since the following business day. In plain terms, the path is no longer a matter of interpretation. It is the rule. The amparo, a constitutional protection tool, remains available as a safeguard in the rare case an authority does not follow it.

The legal process, step by step

Step 1, The surrogacy agreement and power of attorney

Before any embryo transfer, the intended parents and the surrogate sign a detailed agreement that sets out everyone's rights and obligations. It is formalised before a notary, a step known in Mexico as protocolisation, which is the condition the Supreme Court requires for voluntary jurisdiction. At the same time, you sign a power of attorney so the legal team can act on your behalf in Mexico. This is part of Phase 1 of the program, and the payment for that phase is made before the agreement and the power of attorney are signed.

Step 2, Voluntary jurisdiction during the pregnancy

The legal team prepares and files the voluntary jurisdiction proceeding while the surrogate is pregnant, so it does not start from zero once your baby arrives. Its fees are part of Phases 2 and 3 of the program, alongside the transfer and the prenatal care.

Step 3, What the judge verifies

The judge does not resolve a dispute, because there is none. The role is to verify. The jurisprudence lists what the judge checks. The facts arising from the agreement and how it was carried out. Your procreational will as intended parents. That the surrogate gave full, free and informed consent, with clear information on the legal, personal and medical scope of what she agreed to. That she had independent legal advice and received proper medical care throughout the pregnancy. As a general rule, the Public Prosecutor and the Mexico City child protection office (Procuraduría de Protección de Derechos de Niñas, Niños y Adolescentes) are also notified, to protect the rights of the baby and of the surrogate. These safeguards protect everyone involved, and they are exactly what the program is designed around.

Step 4, Birth, certification and registration

After the birth, the judge's resolution is presented to the Civil Registry, which issues the Mexican birth certificate naming the intended parents as the child's legal parents, with no reference to the surrogate. For a couple, both partners are listed. The Mexican passport follows. This corresponds to Phase 5 of the program, which includes the registration legal fees and the surrogate's final payment.

Step 5, Your home country's passport and the trip home

With the Mexican birth certificate in hand, you apply for your baby's citizenship and passport through your country's embassy or consulate. This step follows your home country's rules, so we recommend confirming the requirements with your own authorities early. We have worked with heterosexual and same-sex couples, as well as single intended parents, from all over the world, and the legal team prepares the Mexican documents you will need to present. Michaël helps you plan your stay and the trip home around it.

Who can be recognised as a legal parent?

Because parentage flows from procreational will and the 2021 ruling removed restrictions based on who you are, the process recognises heterosexual couples, same-sex couples, and single intended parents equally, whatever their nationality. For same-sex couples, both partners are named on the birth certificate. You can read which program fits each situation on the main surrogacy program page.

Why a genetic link usually matters

In most cases, at least one intended parent should have a genetic connection to the child. In Mexico, parentage rests on procreational will, but your home country may look at things differently, and many countries pass citizenship through a genetic parent. A genetic link on at least one side usually makes that part much simpler. Where it is not possible, the situation is more complex and can call for extra steps at home. Dr. Castillo Peláez and Rafael Guzmán Romero assess this with you at the start, including how donor egg IVF keeps a genetic link on one side, so you know where you stand before committing.

How long does the legal process take?

The legal work runs alongside the medical journey rather than after it. The agreement and power of attorney are signed in the first months, before the transfer. The voluntary jurisdiction proceeding moves forward during the pregnancy. After the birth, the birth certificate and Mexican passport are issued, followed by your home country's passport.

Exact timing depends on the court and on your home country's consulate. Plan to stay in Mexico City for roughly two to four weeks after the birth to complete the registration and your consular paperwork. Michaël shares a personalised calendar with every step and every payment date once your carrier is matched.

The legal team inside the program

The legal work is not handed off to an outside agency. Rafael Guzmán Romero is in charge of surrogate management and all legal aspects of the program. His team drafts your agreement and carries it through protocolisation, the voluntary jurisdiction proceeding and the final registration, providing legal certainty from the signing of the contract to the birth certificate in your names.

Their fees are already built into the program price, split across the phases. Contract and protocolisation in Phase 1, voluntary jurisdiction in Phases 2 and 3, and registration in Phase 5. Nothing is added on top. You can see the full breakdown on the cost page.

This page explains the general framework in Mexico City as it stands in 2026. It is not legal advice for your particular case, and your own country's rules matter just as much. The legal team reviews your situation before you commit and will tell you plainly if Mexico City is not the right fit. Reach Michaël to book your consultation.

Common legal questions about surrogacy in Mexico City

Is surrogacy legal in Mexico City for foreigners?

Yes. The 2021 Supreme Court ruling prohibits excluding anyone on the basis of nationality, marital status or sexual orientation, and the 2026 jurisprudence applies the same way whether you live in Mexico or abroad.

Will the surrogate have any parental rights over the baby?

No. Through voluntary jurisdiction, the intended parents are named on the birth certificate and the surrogate is never recorded as the mother. Mexican law bases parentage on procreational will, the intention to be a parent, not on who carries the pregnancy.

Do we have to adopt our own child?

No. There is no adoption step in Mexico. The intended parents are recognised as the legal parents directly on the birth certificate. Some home countries have their own requirements after you return, and the legal team flags this early if it applies to you.

Why does the 2026 jurisprudence matter for us?

Before it, the outcome could depend on which judge received your case. Now the Supreme Court has set the route and every court in the country must follow it, which makes the process predictable for you from the day you sign.

What happens if the Civil Registry refuses to register us?

This is now unlikely, because the jurisprudence states that the judge's resolution is full proof for issuing the birth certificate. If an authority still hesitates, the amparo remains available as a constitutional safeguard, and the legal team knows how to use it.

Is the surrogacy agreement enforceable?

The agreement is drafted by the legal team, signed before a notary, and reviewed by the judge as part of voluntary jurisdiction. The surrogate always keeps autonomy over her own body during the pregnancy. The agreement governs parentage, responsibilities and support, and it does not override her medical rights.

When are the legal fees paid?

They are included in the program phases, so there is no separate legal bill. The contract and protocolisation fees are part of Phase 1, paid before signing. The voluntary jurisdiction fees are part of Phases 2 and 3, and the registration fees are part of Phase 5.

How do we get our baby home?

Your baby receives a Mexican birth certificate and Mexican passport, and then you apply for your home country's passport at your embassy or consulate in Mexico. This follows your country's rules, so confirm the requirements with your own authorities early. The legal team prepares the Mexican documents, and Michaël helps you plan the trip home.
