What Happens If One Parent Wants Another Child Using Frozen Embryos?
Frozen embryos can lead to serious legal disputes when former spouses disagree about having another child. One person might see the embryos as their last chance for a genetically related child, while the other may not want to become a parent again. This disagreement can come up during a divorce, years after the divorce, or even after the couple has started raising children together. Illinois law treats this issue differently from other property disputes because using an embryo can create a new person and have lasting legal effects. The outcome often depends on fertility-clinic consent forms, marital settlement agreements, written withdrawals of consent, and when the embryo transfer is proposed.
When I handle these disputes, I first check exactly what documents the parties signed and when. I also look at whether anyone later withdrew consent, if the divorce judgment mentioned the embryos, and if the fertility clinic got any conflicting instructions. These details can decide if one former spouse can move forward with an embryo transfer or if the embryos must stay in storage until the dispute is settled.
Illinois Law Gives Written Agreements Significant Importance
Current Illinois law directly addresses disagreements involving cryopreserved fertilized ova. Under 750 ILCS 46/704.5, when intended parents no longer agree about using cryopreserved fertilized ova for medical purposes, 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 a civil union governs their disposition.
Because of this law, the wording and timing of these documents are very important. A fertility-clinic form might say what happens after divorce, whether both people must agree to future use, if one person gets control, or if the embryos should be donated, discarded, or kept in storage. A later marital settlement agreement can change or replace earlier instructions if it clearly covers the embryos and is included in the divorce judgment.
General language about dividing property usually isn’t enough. Frozen embryos involve unique reproductive issues that are very different from splitting up bank accounts, cars, or household items. In any divorce agreement involving embryos, I recommend clearly stating who controls them, whether they can be transferred, who pays for storage, and what happens if either person changes their mind later.
An Intended Parent May Withdraw Consent Before Transfer
The Illinois Parentage Act also addresses withdrawal of consent to assisted reproduction. Under 750 ILCS 46/704, an intended parent may withdraw consent before an insemination or embryo transfer that results in pregnancy. The withdrawal must be made in writing or in a legal pleading, with notice provided to the other participants and any clinic or health care providers facilitating the procedure.
If someone properly withdraws consent before the transfer, they are not considered a parent of any resulting child under this law. Timing is very important. Anyone who objects to further use should not rely on verbal objections, casual messages, or assume the clinic already knows about the disagreement. Formal written notice is often needed to protect your legal rights and stop an unauthorized transfer. Illinois law also permits an intended parent to withdraw consent to the use of that person’s gametes before insemination or in vitro fertilization. Once eggs and sperm have already been combined and frozen embryos exist, the dispute turns more directly on the governing informed consent or marital settlement agreement. That distinction makes early legal action particularly important.
The Fertility-Clinic Forms May Control The Outcome
Many couples fill out several forms before starting IVF, but they may not realize these documents can later decide what happens to the embryos. Consent forms often include choices about divorce, separation, death, missed storage payments, long-term storage, and disagreements between the intended parents.
A spouse who wants to use the embryos may argue that the signed form grants individual control or permits continued use following divorce. The opposing spouse may point to language requiring mutual consent for any future transfer. The court may need to determine which form was executed most recently, whether the instructions are clear, and whether a subsequent marital settlement agreement changed them.
I recommend getting the full fertility-clinic file instead of just looking at a single page from one party. The file may include updated choices, acknowledgments, storage agreements, messages with clinic staff, and documents signed during later treatments. These materials can show what both parties intended and help identify which agreement Illinois law says must be followed.
Illinois Courts Have Previously Balanced Competing Reproductive Interests
Before the 2025 statutory amendments provided more specific direction, the Illinois Appellate Court addressed embryo disputes in Szafranski v. Dunston. The court adopted a two-step approach. It first looked for an agreement governing the embryos. If no enforceable agreement existed, the court weighed the parties’ competing interests in using or preventing the use of the embryos.
In that case, the court allowed the woman to use the embryos because there was evidence of an agreement letting her do so, and it was her only chance to have a genetically related child. The court focused on the specific facts, like why the embryos were created and her loss of fertility after cancer treatment.
The current version of 750 ILCS 46/704.5 now expressly identifies the most recent fertility-center informed consent or a marital settlement agreement as governing when intended parents disagree. Szafranski remains important background concerning the seriousness of reproductive interests and the importance of proving intent, but disputes arising today must be evaluated under the amended statute.
Using An Embryo Is Different From Determining Parenting Time
The decision about whether an embryo may be used occurs before a resulting child exists. Parenting time, sometimes still called visitation, concerns the relationship between a legal parent and a child who has been born. These are related legal questions, but they are not the same question.
If an embryo transfer results in a child and both former spouses are legal parents, future parenting issues are governed by the Illinois Marriage and Dissolution of Marriage Act. Under 750 ILCS 5/602.7, a court must allocate parenting time according to the child’s best interests. The court may consider the child’s needs, each parent’s prior caretaking role, the parents’ ability to cooperate, the distance between their homes, and each parent’s willingness to support the child’s relationship with the other parent.
An embryo agreement usually cannot set the final parenting schedule for a future child. Even if the parents shared their expectations before conception, the court must look at the child’s real situation after birth. The child’s well-being, not the parents’ earlier plans, guides the parenting-time decision.
Decision-Making Responsibilities May Also Become Disputed
If both parties are ultimately recognized as parents, the court may also need to allocate significant decision-making responsibilities under 750 ILCS 5/602.5. Those responsibilities may involve education, health care, religion, and extracurricular activities. The court must consider the child’s best interests and the parents’ ability to make decisions together.
A former spouse who opposed the embryo transfer may believe that the objection eliminates all future parental responsibilities. That conclusion should not be assumed. Parentage depends on the applicable consent rules, the timing and effectiveness of any withdrawal, and the facts surrounding the assisted reproduction process.
If only one person is legally recognized as the intended parent, the parenting-time situation can be very different. That’s why it’s important to sort out embryo disposition, consent, and parentage before anyone tries to move forward with a transfer.
Child Support Cannot Be Resolved Through Informal Promises
Someone who wants to use the embryos might promise not to ask the former spouse for child support. However, that promise may not give either person the certainty they want. Child support is considered a right of the child, and parents usually cannot take away that right with a private agreement that goes against Illinois law or the child’s best interests.
Whether a former spouse could become responsible for support may depend on whether that person is legally considered a parent under the Illinois Parentage Act. A valid pre-transfer withdrawal of consent may therefore have major consequences. Conversely, failing to complete an effective withdrawal or proceeding under an agreement that identifies both individuals as intended parents may create future parentage and support issues.
I advise clients not to rely on oral assurances about support, involvement, or future contact. The parties should obtain legal advice concerning the parentage consequences before any embryo transfer occurs.
Existing Children Do Not Decide The Embryo Dispute
The parties may already share one or more children created during the relationship. One parent may argue that using the remaining embryos would give those children a genetically related sibling. The other may argue that another birth would increase conflict, alter existing parenting arrangements, or create additional financial obligations.
Those concerns may explain each person’s position, but the parenting-time rights of existing children do not automatically determine whether a frozen embryo may be transferred. The court must first consider the documents and consent provisions governing the embryos. Parenting plans for existing children remain subject to their own best-interest analysis under 750 ILCS 5/602.7.
The parents should also avoid involving their children in the dispute. Asking a child to take sides or discussing sensitive reproductive issues in an age-inappropriate manner can damage family relationships and may become relevant in later parenting litigation.
Immediate Legal Action May Be Necessary
A person who learns that a former spouse intends to use disputed embryos should act promptly. Delayed action may allow the clinic to proceed before it receives formal notice of an objection. Depending on the circumstances, it may be necessary to send written notice, request preservation of the embryos, seek disclosure of clinic records, or ask a court for temporary injunctive relief.
The person seeking to use the embryos should also obtain legal advice before scheduling a transfer. Proceeding despite disputed consent can lead to emergency litigation, clinic delays, parentage disputes, and substantial legal expense. A careful review of the most recent consent documents and divorce judgment may prevent a decision that cannot later be reversed.
Protecting Your Rights In An Illinois Frozen Embryo Dispute
A disagreement over frozen embryos may affect reproductive autonomy, parentage, child support, and the future structure of a family. I represent individuals on either side of these disputes, including a person seeking to use embryos and a person objecting to further use. I also handle related divorce, allocation of parental responsibilities, parenting-time, visitation, paternity, and family law matters. The first step is a careful review of the fertility-center records, written consents, divorce judgment, and any later communications between the parties.
