Yes—but “change her mind” can mean several different things. A gestational carrier always keeps authority over medical care involving her body. A properly prepared surrogacy agreement may still protect the intended parents’ legal parentage and define what happens if someone does not follow an agreed term. One does not cancel out the other.
That distinction matters. It can lower fear without giving anyone false certainty. The details also depend on state law, the signed agreement, and the facts of the case. Intended parents and the carrier should each have independent surrogacy counsel.
Three questions hidden inside “Can she change her mind?”
People often use one phrase for three very different situations:
- Before embryo transfer: A participant may develop concerns about the match, treatment, or timing. The clinic can pause when consent or required clearance is missing. The agreement and local law will shape any legal or financial consequences.
- During treatment or pregnancy: The carrier decides whether to accept a medication, test, procedure, or other medical care involving her body.
- About legal parentage: Parentage is governed by applicable law and the legal steps taken by the parties. It is not decided only by how someone feels on a difficult day.
If you are still learning how these pieces fit together, start with the surrogacy path for intended parents.
Bodily autonomy continues throughout the pregnancy
The American Society for Reproductive Medicine, or ASRM, is direct on this point. Its Ethics Committee says the gestational carrier is the sole source of consent for her medical care. That covers embryo transfer, prenatal care, labor, delivery, and aftercare.
Intended parents have deep emotional and practical interests in the pregnancy. They may also have preferences that everyone discussed in advance. Still, a contract cannot make someone undergo or refuse a procedure.
This is not a flaw in surrogacy. It is the same basic principle of informed consent that applies in health care more broadly.
A concrete moment when the distinction matters
At a mid-pregnancy ultrasound, the doctor sees something that may need more evaluation. The intended parents want an invasive diagnostic test as soon as possible. The carrier wants to speak with a specialist first because the test has risks.
Their agreement may describe shared expectations about prenatal testing. It may also provide a process for urgent communication. But the carrier still gives or withholds medical consent. A sound team slows the conflict down. The physician explains the options. The mental health professional helps everyone communicate. Each attorney advises their own client.
The goal is not to “win” control. It is to make an informed decision while protecting the relationship and everyone’s legal rights.
What a surrogacy contract can—and cannot—do
| A careful agreement can | An agreement cannot |
|---|---|
| Record the parties’ intent about parentage | Replace the carrier’s medical consent |
| Set expectations for communication, expenses, insurance, travel, and delivery | Force a medication, test, surgery, termination, or reduction |
| Address views on embryo transfer, prenatal testing, and difficult pregnancy decisions | Predict every medical event or emotional response |
| Define a dispute-resolution process and possible consequences of breach | Guarantee a pregnancy, birth outcome, or conflict-free relationship |
| Support the required parentage process under applicable law | Substitute for independent legal advice |
The contract is still essential. It turns broad goodwill into specific expectations. It also gives the parties and their advisers a shared document when memories or emotions differ.
California shows why parentage is a separate issue
California Family Code section 7962 provides one useful example, though it is not a rule for every state. Among other requirements, the statute calls for separate independent attorneys before the agreement is signed. It also says the agreement must be fully executed before embryo transfer or injectable medication used to prepare for transfer begins.
When the statutory requirements are met, the agreement is presumptively valid. The law provides a route for a court order establishing the intended parents as parents and stating that the gestational carrier has no parental rights or duties. The statute also says a compliant agreement cannot be rescinded or revoked without a court order.
That does not let intended parents direct the carrier’s health care. It means a disagreement about medical care and a claim about legal parentage are not the same dispute.
Because laws vary, intended parents should plan the surrogacy parentage order with an attorney licensed in the relevant state.
Why alignment before transfer is so important
ASRM recommends that intended parents and carriers address hard topics before treatment. These include the number of embryos to transfer, prenatal testing, pregnancy termination, multifetal reduction, obstetric complications, and delivery preferences. ASRM also advises against moving forward when serious misalignment or lack of respect becomes clear.
This conversation should go beyond yes-or-no answers. Ask what each person would need in order to make a decision. Discuss who joins a medical call, how quickly updates are expected, and how disagreement will be handled.
For an English/Spanish bilingual household, decide which language each person wants for complex discussions. Request a qualified interpreter when needed. Do not rely on a relative to translate a legal or medical decision.
What intended parents can do now
You cannot remove every risk. You can build a process that makes surprise and escalation less likely:
- Use separate, experienced attorneys. Confirm which state’s law applies and when the parentage work begins.
- Treat matching as values alignment. Discuss medical decision-making, communication, privacy, social media, pregnancy behavior, delivery, and future contact.
- Complete the joint mental health session before treatment. Use it to test how the group handles sensitive questions, not merely to complete a requirement.
- Ask for the conflict pathway in writing. Know who calls the physician, counselor, agency, and attorneys when time matters.
- Respect a pause. A concern raised before transfer is easier to address than the same concern during pregnancy.
Use these questions to ask a surrogacy agency to learn how an agency handles legal clearance, expectation-setting, and conflict support.
The most useful question is not, “Can anyone promise she will never change her mind?” No ethical professional can make that promise. Ask instead: “How will this team protect autonomy, parentage, informed consent, and communication if a hard decision arises?”
