How surrogacy works in Mexico, step by step

What is surrogacy?

Surrogacy, also called surrogate gestation, is an arrangement in which a woman (the surrogate) carries a pregnancy for another person or couple (the intended parents), who will be the baby's legal parents. In gestational surrogacy, the most common form in Mexico, the embryo is created using genetic material from the intended parents or donors; the surrogate does not provide her egg and has no genetic link to the baby.

Tlacati explains the process from the perspective of someone considering becoming a surrogate. We are not a clinic or agency: this page describes what usually happens; the program you choose to speak with sets the exact conditions in writing.

The seven stages, in order

1. 1. First conversation

   You ask questions and share the essentials: where you live, whether you have had a previous pregnancy and how much time you have available. No documents or commitments. With Tlacati, this stage takes place on WhatsApp and you can stop at any time.

2. 2. Referral to a program

   Only with your permission is your profile shared with an agency or program. They contact you and explain how they work, which city they operate in and what requirements apply. It is a good idea to ask for everything in writing from the start.

3. 3. Assessments

   The program coordinates medical tests (gynecological examinations, laboratory tests and ultrasound) and a psychological assessment. These aim to confirm that pregnancy would be safe for you and that your decision is free and informed. Who pays for tests, travel and medication should be clear before you start.

4. 4. Contract

   Once the intended parents have been identified, a contract is signed documenting payments, expenses, insurance, obligations, privacy and what happens if the process changes or ends. You should receive a full copy, time to read it and, preferably, independent legal advice. Our contract review guide lists the key questions.

5. 5. Preparation and transfer

   Medication is used to prepare the uterus, and the embryo is transferred at an assisted reproduction clinic. It is a brief outpatient procedure. A blood test a few days later confirms whether implantation occurred. More than one attempt may be needed; the contract should state what happens in each case.

6. 6. Pregnancy with follow-up care

   Pregnancy is supported with prenatal appointments, tests and communication with the program. Availability matters here: appointments, rest when prescribed and reporting any problems. Expenses and protections for this stage should be set out in writing.

7. 7. Birth and legal procedures

   After birth, procedures are completed to list the intended parents on the birth certificate. The procedure depends on the state and applicable legal framework; in 2026 the Supreme Court established a standard for Mexico City. We explain it in Legal framework.

How long does it take?

There is no fixed timeline. Several months often pass between the first conversation and a transfer because assessments, the contract and coordination with the clinic are involved. Pregnancy follows its own course, and subsequent legal procedures vary by state. A responsible program will provide an approximate written timeline and explain what could affect it.

Who does what

• You: make decisions at each stage, attend appointments and care for your health according to medical guidance.
• The program or agency: coordinates assessments, the clinic, the contract, payments and communication with the intended parents.
• The clinic: carries out tests, preparation, transfer and medical follow-up.
• Lawyers and the notary: formalize the contract and legal parentage procedures.
• Tlacati: provides information before you start and, if you ask, makes a referral. We do not take part in assessments, contracts or payments.
