Can My Ex Stop Me From Using Embryos We Created While Married?

Frozen embryos can be one of the hardest issues to face in a divorce because they are more than just property. They may offer the hope of having a biological child, but also bring up questions about consent, parentage, and whether a former spouse can be made a parent against their wishes. Illinois law now addresses disputes over assisted reproduction and frozen embryos, including what happens if intended parents no longer agree on their use.
If you and your ex created embryos during your marriage and you want to use them, it is not as simple as saying the embryos belong to both of you equally. The documents you signed, the timing of any consent or withdrawal, and your divorce settlement all matter. I recommend reviewing these issues carefully before scheduling an embryo transfer or assuming that an old IVF consent form gives you the right to proceed.
Illinois Law Allows Withdrawal Of Consent Before Embryo Transfer
Illinois law gives an intended parent the ability to withdraw consent to assisted reproduction before an insemination or embryo transfer that results in pregnancy. Under 750 ILCS 46/704, an intended parent may withdraw consent in writing or through a legal pleading, with notice to the other participants and the clinic or health care provider involved. An intended parent who properly withdraws consent before insemination or embryo transfer is not considered a parent of a resulting child under that provision.
This becomes especially important after a separation or divorce. A spouse who agreed to IVF during the marriage may later decide they do not want the embryos used to have a child. If consent is withdrawn before the embryo transfer, that choice can affect whether the procedure goes forward and what parentage rights or responsibilities the former spouse may have.
Timing is crucial. Once a pregnancy begins from an embryo transfer, the legal situation changes a lot. That’s why I do not recommend relying on an old IVF consent form without checking if consent is still valid or if it has been withdrawn since then.
The Fertility Clinic Agreement May Control The Dispute
Illinois added a specific provision addressing disputes over cryopreserved fertilized ova. Under 750 ILCS 46/704.5, if intended parents no longer agree about the use of cryopreserved fertilized ova for medical purposes, the terms of the most recent informed consent executed at the fertility center, or a marital settlement agreement entered under a judgment of dissolution, legal separation, or dissolution of civil union, govern disposition.
This is why the paperwork from the fertility clinic is so important. Many couples sign detailed forms before IVF that explain what will happen to embryos if there is a divorce, separation, death, incapacity, or disagreement. These details may seem distant or unlikely at the time, but after a divorce, they can be key to deciding if one former spouse can use the embryos.
I recommend looking at the exact wording of the most recent consent form instead of relying on memories from years ago. The document might say that both parties must agree to future use, that the embryos will be destroyed after divorce, that one spouse gets control, or that another agreed method will be used.
A Marital Settlement Agreement Can Also Decide What Happens
If the divorce has already been finalized, the marital settlement agreement should be reviewed carefully. Illinois law expressly recognizes a marital settlement agreement under a judgment of dissolution as a document that may govern the disposition of cryopreserved fertilized ova when the former spouses no longer agree.
This means you should not treat the question of what happens to embryos as an afterthought during divorce talks. If embryos exist, the settlement should clearly address them. Vague language can lead to legal disputes later, especially if one person wants to use the embryos and the other does not.
The agreement should clearly state whether either person can use the embryos, if both must agree, if the embryos must stay in storage, and if donation or destruction is allowed. Being clear during the divorce can help prevent a very personal dispute from ending up in court years later.
Marriage Does Not Automatically Give Either Spouse Unilateral Control
The fact that embryos were created during the marriage does not automatically mean either former spouse may decide alone what happens to them. Embryo disputes are not treated exactly like disputes over ordinary marital assets because reproductive autonomy and parentage are involved.
Illinois law now puts a lot of weight on informed consent and the right to withdraw it. A spouse who provided genetic material may have agreed to one plan during the marriage but later changed their mind before the embryo transfer. So, the details, documents, and timing matter much more than just whose name is on the storage account.
This is also why I would not describe embryos as just another marital asset. A bank account can usually be divided financially. An embryo carries the potential for future parentage, which raises fundamentally different legal concerns.
Parentage Rights Can Depend On Consent
The Illinois Parentage Act addresses parentage arising through assisted reproduction. Consent is central to that framework. Section 704 provides that an intended parent who withdraws consent before insemination or embryo transfer is not a parent of a resulting child.
That provision helps explain why courts and fertility clinics take consent disputes seriously. If one former spouse wants to proceed with an embryo transfer while the other has formally withdrawn consent, the issue is not limited to control over biological material. It may also affect whether that person can later be treated as a legal parent.
These questions can have consequences for parental responsibilities, parenting time, and financial obligations after birth. The analysis should therefore occur before treatment proceeds, not after a pregnancy has already begun.
Parenting Time Is A Separate Issue Once A Child Exists
If a child is ultimately born through assisted reproduction and legal parentage is established, future parenting disputes are governed by Illinois family law rather than the original IVF disagreement alone. Under 750 ILCS 5/602.7, Illinois courts allocate parenting time according to the child’s best interests. The court considers factors including each parent’s relationship with the child, prior caretaking functions, the child’s needs, the child’s adjustment to home and community, and each parent’s willingness to support the child’s relationship with the other parent.
In other words, a dispute over embryo use and a later dispute over parenting time are legally distinct. The IVF consent documents may help determine whether a person is legally recognized as a parent, but once parentage is established, parenting time is governed by the child’s best interests.
That distinction is important because people sometimes assume that consenting to IVF automatically guarantees a particular custody arrangement later. It does not.
Do Not Schedule A Transfer Until The Legal Documents Have Been Reviewed
If your former spouse objects to embryo use, I would not recommend moving forward with a transfer until the legal documents have been reviewed. Proceeding while consent is disputed can create serious legal problems and may place the fertility clinic in the middle of a conflict.
The most important documents usually include the fertility-center consent forms, storage agreements, any amendments to those forms, the divorce judgment, the marital settlement agreement, and any correspondence showing withdrawal of consent. The dates and sequence of those documents can be critical.
A careful review can determine whether the existing agreement permits use, requires mutual consent, or directs another disposition. It can also identify whether further court involvement may be necessary before the embryos can lawfully be used.
Frequently Asked Questions About Using Frozen Embryos After Divorce In Illinois
Can My Ex Stop Me From Using Our Frozen Embryos?
Possibly. Illinois law permits an intended parent to withdraw consent to assisted reproduction before an insemination or embryo transfer that results in pregnancy. In addition, 750 ILCS 46/704.5 provides that when intended parents disagree about the medical use of cryopreserved fertilized ova, the most recent fertility-center informed consent or a qualifying marital settlement agreement governs disposition.
That means the answer often depends on what you and your former spouse previously signed and whether consent was later withdrawn. I would review those documents before assuming either person has unilateral authority.
Does It Matter That The Embryos Were Created While We Were Married?
Yes, but marriage alone does not automatically resolve the dispute. The embryos may have been created as part of a joint reproductive plan during the marriage, but Illinois law focuses heavily on consent and the documents governing disposition.
The fertility agreement may say what happens after divorce. A later marital settlement agreement may also govern. The fact that both parties originally intended to become parents does not necessarily mean that consent can never be withdrawn.
What If Our IVF Agreement Says I Can Use The Embryos After Divorce?
That language could be highly significant. Section 704.5 directs attention to the most recent informed consent executed at the fertility center or a marital settlement agreement when intended parents later disagree about use.
However, the exact wording matters. I would want to know whether the agreement expressly permits unilateral use, whether both parties agreed to future parentage, whether later documents modified the original terms, and whether consent was withdrawn before transfer.
Can My Ex Withdraw Consent After Signing IVF Forms?
Illinois law allows an intended parent to withdraw consent to assisted reproduction before an insemination or embryo transfer that results in pregnancy. The withdrawal must be made in writing or through a legal pleading with appropriate notice.
That means a prior consent form does not always guarantee that consent remains irrevocable indefinitely. The legal effect of withdrawal should be evaluated together with the disposition provisions in the fertility agreement and any divorce settlement.
What Happens If My Ex Withdraws Consent Before Transfer?
Under 750 ILCS 46/704, an intended parent who withdraws consent before insemination or embryo transfer is not a parent of a resulting child under that provision.
The withdrawal can therefore affect both parentage and whether the transfer should proceed. If the former spouses disagree, the fertility-center consent documents and marital settlement agreement may determine disposition under Section 704.5.
Can A Divorce Settlement Give Me Control Of The Embryos?
Yes. Illinois law expressly recognizes a marital settlement agreement under a judgment of dissolution as a document that can govern the disposition of cryopreserved fertilized ova when the parties disagree.
For that reason, embryo disposition should be addressed specifically during divorce negotiations. The agreement should state what happens to the embryos and whether either party has future authority to use them.
Can My Ex Be Forced To Become A Parent If I Use The Embryos?
That depends on consent and timing. Illinois law provides that an intended parent who withdraws consent before insemination or embryo transfer is not a parent of the resulting child under Section 704.
This is one of the reasons embryo-use disputes must be resolved before transfer whenever possible. Parentage affects much more than biology. It can affect parental responsibilities, parenting time, and support obligations.
Does The Fertility Clinic Have To Follow Our Divorce Agreement?
The relationship between the clinic documents and divorce agreement should be reviewed carefully. Section 704.5 specifically identifies both the most recent fertility-center informed consent and a marital settlement agreement under a divorce judgment as governing documents when parties disagree about disposition.
A clinic may also have its own procedural requirements before acting on a divorce judgment or consent withdrawal. Providing the clinic with accurate legal documentation is therefore important.
If A Child Is Born, Does The IVF Agreement Decide Custody?
No. Once a child exists and legal parentage is established, parenting time is determined under Illinois family law. Under 750 ILCS 5/602.7, the court must allocate parenting time based on the child’s best interests.
An IVF agreement may help determine reproductive consent and parentage issues, but it does not permanently predetermine how parenting time will be allocated years later.
What Should I Do If I Want To Use Frozen Embryos And My Ex Objects?
The first step should be a legal review of every document connected to the embryos. I would want to see the fertility-center consent forms, storage agreements, divorce judgment, marital settlement agreement, any later amendments, and any written withdrawal of consent.
Do not assume the clinic will allow a transfer simply because you are one of the intended parents. Illinois law gives significant weight to the documents governing consent and disposition, and resolving the issue before treatment proceeds can prevent far more serious litigation later.
