Can You Modify An IVF Agreement After It Has Been Signed?
An IVF agreement may be signed during a hopeful period when both partners share the same plans for building a family. Those plans can change because of separation, divorce, illness, financial hardship, religious concerns, or a change in one person’s desire to become a parent. When that happens, one or both parties may want to revise provisions concerning frozen embryos, future implantation, storage costs, donation, or destruction. In Illinois, modifying an IVF agreement may be possible, but a person usually cannot change a binding agreement merely by announcing that he or she has changed positions. The original document, the parties’ later conduct, fertility clinic procedures, Illinois contract law, and the timing of the proposed change can all affect whether a modification is valid.
I advise clients to treat every IVF document as a potentially important legal agreement rather than routine medical paperwork. A consent form signed at a fertility clinic may contain provisions that become highly significant during a divorce or breakup. Separate agreements between spouses or unmarried partners may also affect who controls embryos and whether either person may use them. Because assisted reproduction can involve contractual rights, reproductive interests, parentage, and future parenting issues, any proposed amendment should be carefully documented before medical treatment continues.
Whether An IVF Agreement Can Be Changed Depends On Its Terms
The first step is to read the signed agreement closely. Many IVF agreements contain a section explaining whether amendments are permitted and what must be done to make a change effective. A document may require a written amendment signed by both parties, approval from the fertility clinic, notarized signatures, or the completion of new consent forms. When an agreement contains a specific modification procedure, failing to follow that procedure may create a serious dispute over whether the change is valid.
Some agreements also state that neither party may revoke or alter certain instructions without the other person’s written consent. In that situation, one party’s private email, verbal objection, or telephone call to the clinic may not be enough to amend the agreement. The clinic may temporarily suspend treatment while the dispute is addressed, but suspension of medical services is not necessarily the same as a legally effective contract modification.
I also examine whether the agreement addresses what happens after separation, divorce, death, or incapacity. If the document already contains instructions for those events, a court may view those provisions as evidence that the parties anticipated the possibility of changed circumstances when they signed.
Mutual Consent Is Usually The Safest Method Of Modification
The clearest way to modify an IVF agreement is through a new written document signed by everyone whose rights are affected. The amendment should identify the original agreement, state exactly which provisions are being replaced, and confirm that all remaining terms continue in effect. Both parties should receive copies, and the fertility clinic should confirm that the amendment has been accepted into its records.
A valid contract modification generally requires mutual assent. In practical terms, both parties must clearly agree to the new terms. One person cannot ordinarily rewrite an agreement by making a handwritten change, sending a unilateral demand, or signing a separate document that the other party never accepts.
The amendment should also address whether prior clinic forms conflict with the new instructions. Couples sometimes sign several documents over the course of treatment, and those documents may contain inconsistent provisions. A properly prepared amendment can identify which document controls and reduce the risk of future litigation over the parties’ intentions.
A Change Of Mind May Not Cancel The Original Agreement
A change of heart can be emotionally genuine without being legally sufficient to cancel an agreement. One partner may no longer want an embryo used after the relationship ends, while the other may view the embryos as the only realistic opportunity to have a genetically related child. These competing interests can create a difficult dispute, but the existence of strong emotions does not automatically eliminate contractual obligations.
In Szafranski v. Dunston, 2015 IL App (1st) 122975-B, the Illinois Appellate Court addressed a dispute over cryopreserved pre-embryos created by an unmarried couple. The court gave priority to the parties’ agreement and examined their intent at the time it was formed. The decision demonstrates why conversations, clinic forms, emails, draft agreements, and later conduct may become important evidence when the parties disagree about what was originally promised.
Illinois courts generally do not create new contract terms for parties after a dispute develops. Therefore, a person seeking to modify an IVF agreement should not assume that a court will simply replace the original terms with what appears fair at the time of the lawsuit. The wording of the agreement and the evidence of mutual intent can be decisive.
The Timing Of The Requested Change Can Matter
Modification is generally easier before eggs are retrieved, embryos are created, or either party has relied on the original agreement. Once the parties have completed medical procedures, paid substantial expenses, created embryos, or made life decisions based on the signed document, changing the arrangement may become more difficult.
Timing becomes even more critical before an embryo transfer. Once an embryo has been transferred and a pregnancy begins, the legal questions are no longer limited to control or disposition of stored embryos. Parentage, prenatal decision making, and the rights and responsibilities arising after birth may become relevant.
A person who wishes to change an agreement should act promptly and provide clear written notice to the other party and the fertility clinic. Delay may allow additional treatment to occur under the original instructions. Prompt action does not guarantee that the proposed modification will be accepted, but it can help prevent further medical steps while the disagreement is reviewed.
Illinois Parentage Law Can Affect The Consequences Of A Modification
The Illinois Parentage Act of 2015 addresses parentage involving assisted reproduction. Under 750 ILCS 46/703, an individual who consents to assisted reproduction with the intent to become a parent is a legal parent of the resulting child when the statutory requirements are met. The statute permits consent to be established through a signed record and, in certain circumstances, through other evidence demonstrating an agreement to parent.
This means that changing instructions about embryo storage or disposition is not always the same as changing consent to legal parentage. An amendment should clearly distinguish between control of embryos, permission for medical use, and intent to become a parent. Ambiguous language can leave the parties disputing whether a person agreed only to help create embryos or also intended to assume parental rights and responsibilities.
Under 750 ILCS 46/702, a donor is generally not considered a parent of a child conceived through assisted reproduction. However, whether someone qualifies as a donor or an intended parent depends on the facts, applicable documents, and statutory requirements. A poorly written amendment could create uncertainty about an individual’s intended legal role.
Divorce Can Make IVF Modifications More Complicated
When spouses separate or file for divorce, frozen embryos may become part of a broader dispute involving property, reproductive rights, and contractual obligations. An automatic assumption that embryos will be divided like ordinary marital property is inappropriate because embryos present personal and constitutional concerns that bank accounts, vehicles, and real estate do not.
A divorce settlement may include terms concerning storage, use, donation, or destruction of embryos, but the settlement language should be coordinated with the original IVF agreement and the clinic’s consent documents. A divorce judgment that says one thing while the fertility clinic’s records say another can produce further conflict.
I also caution clients against signing an amendment during a period of pressure or emotional distress. An agreement obtained through coercion, fraud, material misrepresentation, or lack of meaningful consent may face an enforceability challenge. Each spouse should have sufficient time to review the proposed terms and should consider obtaining independent legal advice before signing.
Parenting Time Cannot Be Permanently Controlled By An IVF Agreement
An IVF agreement may document who intends to become a parent, but it cannot permanently determine parenting time after a child is born. Illinois courts allocate parenting time according to the child’s best interests under 750 ILCS 5/602.7. The court considers factors such as the child’s needs, each parent’s prior caretaking role, the child’s relationship with each parent, the parents’ ability to cooperate, and each parent’s willingness to support the child’s relationship with the other parent.
Significant decision-making responsibilities are addressed under 750 ILCS 5/602.5. These responsibilities may concern education, health, religion, and extracurricular activities. Even when an IVF agreement includes expectations about future parenting, a court is not required to enforce a provision that conflicts with the child’s welfare.
The distinction is important. Adults may enter enforceable agreements about financial obligations, medical consent, or embryo disposition, but they cannot bargain away a child’s right to support or prevent a court from issuing parenting orders based on current circumstances.
Clinic Consent Forms Should Not Be Modified Informally
Fertility clinics usually maintain detailed consent forms covering medical procedures, storage, embryo transfer, and disposition. These documents may also state what happens if the parties divorce, separate, die, fail to pay storage fees, or cannot be located. Because the clinic relies on those instructions, informal side agreements may not be enough to authorize a change in treatment.
A couple may agree privately to modify their arrangement but fail to notify the clinic. If the clinic continues acting under the original consent forms, the private amendment may not prevent delay, confusion, or litigation. Conversely, signing a new clinic form without reviewing a separate legal agreement may create conflicting obligations.
Before treatment continues, the clinic should confirm in writing which instructions are currently effective. Any amendment should be placed in the medical and legal files, and each party should retain a complete copy.
Independent Legal Advice Can Strengthen The Amendment
When both parties use the same attorney, conflicts may arise because changing the agreement could benefit one person while limiting the other person’s reproductive options. Independent representation allows each party to understand the proposed amendment, its risks, and the legal consequences of signing.
Separate legal advice may also help demonstrate that the amendment was entered voluntarily and with informed consent. This can become important if one party later claims that the document was misunderstood or signed under pressure.
A carefully prepared modification should address the immediate issue and foreseeable future events. Those events may include divorce, permanent separation, death, incapacity, unpaid storage fees, disagreement over implantation, and changes in parentage intent. Clear planning is far less costly than asking a court to interpret conflicting documents after the parties’ relationship has ended.
