Embryo disposition agreements are legally enforceable in most states, but how strictly a court will hold you to the terms depends on where the dispute lands. These are the documents signed during IVF that spell out what happens to unused frozen embryos if the couple divorces, one partner dies, or the parties simply finish building their family. Some courts treat them as binding contracts and enforce them as written. Others treat them as a starting point that can be revisited if someone changes their mind. And a handful of state legislatures have passed laws that override the agreement in favor of outcomes the state has chosen.
If you are entering IVF, or you already have embryos in storage, the agreement you signed is doing more legal work than most people realize. It needs to survive divorce court, probate court, and in some states, statutes that did not exist when you signed it.
What the Agreement Needs to Cover
A well-drafted disposition agreement anticipates situations that feel remote when you are focused on getting pregnant but become urgent years later. The agreement is only as useful as the scenarios it addresses.
- Divorce or separation. The agreement should say who gets decision-making authority over the embryos if the relationship ends. Without that, the clinic has no guidance and the dispute heads to court.
- Death of one or both partners. Can a surviving partner use the embryos? Should they be donated or discarded? This overlaps with estate planning in ways many people do not anticipate.
- Method of disposition. When the family is complete, what happens to the remaining embryos? Standard options are donating to another couple, donating to research, or thawing and discarding. Some agreements also allow compassionate transfer, where embryos are thawed and transferred at a time when pregnancy is unlikely.
- Storage duration. Many agreements set a maximum storage period, after which the parties must renew or the clinic follows the default disposition instructions.
- Financial responsibility. The agreement should name who pays annual storage fees and what happens if payments stop. Annual cryopreservation storage typically runs $500 to $1,000, and clinics generally reserve the right to dispose of embryos after extended nonpayment.
The money piece deserves close attention because it creates a ticking clock. If both parties walk away from storage payments after a divorce, the clinic is left holding embryos with no instructions and no revenue. Some clinic contracts contain language releasing all claims to embryos if fees go unpaid, which means losing embryos through inaction rather than choice.
How the Agreement Should Be Signed
Execution formalities matter for enforceability. Many fertility clinics require that changes to disposition instructions be submitted in writing and notarized. Some clinic forms call for a witness who is a clinic employee and at least 18 years old when the agreement is signed in the office, or notarization when signed elsewhere. These requirements exist to make it harder for one party to later claim they did not understand or did not agree to the terms.
Professional guidelines also recommend that each party have independent legal counsel review the agreement before signing. When both partners use the same attorney or rely solely on the clinic’s standard form, a court is more likely to question whether the agreement reflects genuine informed consent. Having a reproductive law attorney review the document typically costs $500 to $2,000, depending on complexity and location.
Changing the Agreement Later
Disposition agreements are not permanent, but changing one requires cooperation. Most clinic contracts and court decisions recognize that either party can change their mind up until the point the embryos are actually used or destroyed. The catch is that a unilateral change of heart does not automatically override the existing agreement. Under the contractual approach that most courts favor, the original agreement stands unless both parties sign a written amendment.
If one party wants to change disposition and the other refuses, the disagreement typically freezes everything in place. The embryos stay in storage until the parties reach a new agreement or a court resolves the dispute. Any change of intention should be communicated in writing to both the other party and the clinic. Verbal statements carry little weight if the matter reaches court.
How Courts Enforce These Agreements
When disputes reach court, judges use one of three frameworks. Which one governs depends on the jurisdiction, and the differences are not academic. They produce opposite outcomes on the same facts.
The Contractual Approach
This is the most common framework and the most predictable. Courts treat the signed disposition agreement as a binding contract and enforce whatever the parties agreed to when they started IVF. The New York Court of Appeals established this approach in Kass v. Kass (1998), holding that agreements between the parties regarding disposition of their embryos “should generally be presumed valid and binding, and enforced in any dispute between them.” Unless there is evidence of fraud, duress, or unconscionability, the written terms control. If the agreement says “donate to research,” that is what happens, even if one party now wants to use the embryos for pregnancy.
The strength of this approach is predictability. The weakness is rigidity. People sign these agreements during an emotionally intense medical process, sometimes years before a divorce forces the question. Feelings about parenthood can shift profoundly, and the contractual approach does not care.
The Balancing Interests Approach
When no agreement exists or the terms are ambiguous, many courts fall back on balancing the competing interests of the parties. This framework traces to Davis v. Davis (1992), the first major American embryo dispute case. The Tennessee Supreme Court held that courts should first look to the parties’ preferences, then to any prior agreement, and finally, if no agreement exists, weigh the relative interests of each person.1The Climate Change and Public Health Law Site. First Embryo Disposition Case – Davis v. Davis, 842 S.W.2d 588, 597 (Tenn. 1992)
In practice, one party argues their right to become a genetic parent while the other argues their right not to be forced into genetic parenthood. Courts weigh factors like whether the party seeking the embryos has other means of having a biological child. The party seeking to avoid procreation usually prevails unless the other party has no realistic path to genetic parenthood. This approach is more flexible than the contractual method and far less predictable. You will not know the outcome until a judge weighs the specific circumstances.
The Contemporaneous Mutual Consent Approach
The Iowa Supreme Court carved out a third path in In re Marriage of Witten (2003), holding that no transfer, release, disposition, or use of embryos can occur without the current signed authorization of both parties.2FindLaw. In Re the Marriage of Arthur Lee Witten III and Tamera Jean Witten Under this rule, a prior agreement is not permanently binding if one party changes their mind. If the parties cannot reach a new agreement, the embryos remain in storage indefinitely. The person opposing destruction bears the ongoing storage costs.
This approach prioritizes current wishes over past intentions and ensures nobody is forced into genetic parenthood against their present will. The trade-off is permanent stalemates. Embryos can theoretically remain frozen forever if the parties never agree, and the financial burden falls on whichever party wants to keep them alive.
State Laws That Can Override Your Agreement
In most states, courts apply one of the three judicial frameworks above. But a few state legislatures have passed statutes that dictate outcomes regardless of what the parties agreed to. If you live in one of these states, your disposition agreement may be partially or entirely overridden by law.
Arizona
Arizona Revised Statutes ยง 25-318.03 requires courts in a divorce to award embryos to the spouse who intends to allow them to develop to birth.3Arizona Legislature. Arizona Code 25-318.03 – Human Embryos; Disposition; Responsibility for Resulting Children The statute is explicit: even if the parties previously agreed to discard the embryos, the court must follow the statutory framework favoring birth. If both spouses want the embryos to develop and both contributed genetic material, the court resolves the dispute “in a manner that provides the best chance for the in vitro human embryos to develop to birth.” If only one spouse contributed genetic material and both want the embryos, the genetic contributor gets them.
The spouse who does not receive the embryos has no parental rights or obligations toward any resulting child, unless they provided genetic material and consent in writing to be a parent. Arizona law can force someone to become a genetic parent over their objection, while simultaneously relieving the non-consenting spouse of any legal relationship to the child.
Louisiana
Louisiana treats embryo disputes through a framework unlike any other state. The law defines an in vitro fertilized human embryo as a juridical person that cannot be intentionally destroyed.4Louisiana State Legislature. Louisiana Revised Statutes 9:129 – Destruction Embryos cannot be owned as property, and neither the clinic nor the treating physician has decision-making authority over them.5Louisiana State Legislature. Louisiana Code RS 9:121 – Human Embryo; In Vitro Fertilization; Definition
When disputes arise, Louisiana law directs courts to resolve them according to the IVF agreement. But there is a critical limitation: any provision directing the intentional destruction of an embryo is automatically void.6Louisiana State Legislature. Louisiana Revised Statutes 9:131 If no agreement exists, courts resolve disputes in the “best interest” of the embryo, which in practice means favoring donation to another couple over destruction. A “thaw and discard” clause signed in Louisiana is legally meaningless.
Florida and Other States
Florida requires IVF patients and their physician to sign a written agreement addressing disposition in the event of divorce, death, or other unforeseen circumstances. A small number of other states have passed legislation either clarifying that existing abortion laws do not apply to IVF or specifying that disposition of embryos before implantation is lawful. The landscape is evolving, and more states are considering legislation in this area. If you are entering IVF, checking your state’s current statutory framework is worth the effort, because a law passed after you sign your agreement could change what provisions are enforceable.
The Personhood Question After LePage
The ground under embryo disposition agreements shifted in 2024 when the Alabama Supreme Court ruled in LePage v. Center for Reproductive Medicine that frozen embryos are “extrauterine children” entitled to the protections of Alabama’s Wrongful Death of a Minor Act.7Justia. LePage v. Center for Reproductive Medicine, P.C. (2024) The court held that the Act “applies to all unborn children, regardless of their location,” including embryos stored in a cryogenic facility.
The fallout was immediate. As one dissenting justice noted, the ruling “almost certainly ends the creation of frozen embryos through in vitro fertilization in Alabama,” because no clinic would risk punitive damages for the accidental destruction of what the court now considers a child.7Justia. LePage v. Center for Reproductive Medicine, P.C. (2024) Alabama subsequently passed emergency legislation to protect IVF providers, but the underlying legal classification remains.
If an embryo is legally a person, contract provisions allowing destruction become far more vulnerable. The same logic could extend to embryos left in indefinite storage. Personhood rulings also create ripple effects in estate and trust law. Legal scholars have raised the possibility that frozen embryos classified as “descendants” could claim distributions from family trusts, or that keeping embryos frozen indefinitely could extend the duration of a trust beyond traditional limits.
The Dobbs v. Jackson decision in 2022, which returned abortion regulation to the states, opened the door for states to define when legal personhood begins. Several states have enacted or proposed fetal personhood statutes that could reach frozen embryos, though most have not yet been tested in the IVF context. For anyone with embryos in storage, this is the single biggest area of legal uncertainty. A disposition agreement that is perfectly enforceable today could become partially void if your state passes a personhood law tomorrow.
Coordinating With Estate Planning
A disposition agreement and a will or trust can easily contradict each other, and most people do not realize it until it is too late. If your will leaves “all property” to your spouse but your disposition agreement directs embryos to be donated to research upon your death, which controls? The answer depends on the jurisdiction and on how the court classifies the embryo, but the conflict itself is avoidable with coordinated planning.
The Revised Uniform Anatomical Gift Act, adopted in some form by most states, explicitly does not cover embryos. The Act’s commentary states that it is “silent on the issue of the use or donation of blastocytes and embryos, neither authorizing nor prohibiting their donation or use.” An organ donation directive will not handle embryo disposition after death. A separate, specific instruction is necessary.
Anyone with frozen embryos should make sure their disposition agreement, will, trust documents, and health care directives all say the same thing about what happens to those embryos. Naming a specific person as an agent for embryo-related decisions, similar to a health care power of attorney, adds another layer of clarity. Without that coordination, a grieving family and a fertility clinic can end up on opposite sides of a probate dispute, with the embryos sitting in a freezer while lawyers argue about intent.
When Clinics Lose or Damage Embryos
Most clinic consent forms include aggressive liability limitations. A typical provision caps the clinic’s total liability at a prorated share of the cost of the IVF cycle that created the embryos. If ten embryos were created and four were destroyed through clinic negligence, the clinic’s exposure might be limited to 40% of the procedure cost. Many agreements also release the clinic from all claims if the patient defaults on storage fees.
Patients who sue after equipment failures or human error typically pursue negligence, breach of contract, medical malpractice, or emotional distress theories. The fundamental problem is that existing tort categories were not designed for the loss of reproductive material. The harm is not easily quantified. It is not a physical injury, it is not exactly property damage, and if embryos have special legal status rather than being pure property, the measure of damages becomes genuinely unclear. Challenging a liability cap in court is possible but far from guaranteed to succeed. Read the cap language before signing the storage agreement, because that is the moment when you still have leverage to ask for changes.
Steps for a Stronger Agreement
Most enforceability problems come from vague language, failure to anticipate common scenarios, or signing whatever the clinic puts in front of you without legal review. A few steps make a meaningful difference.
Have each party represented by an independent attorney. Courts scrutinize agreements more carefully when one party claims they did not fully understand the terms, and independent counsel makes that argument much harder to sustain. Revisit the agreement periodically, because a disposition preference from five years ago may no longer reflect either party’s wishes; most clinics allow written amendments signed by both parties. Be specific. “Donate to research” is clearer than “dispose of appropriately.” Name the exact outcome for every scenario the agreement addresses. Coordinate with your estate planning documents, especially if you have embryos in long-term storage. The disposition agreement should not exist in a vacuum.
Finally, check whether your state has passed or is considering legislation that could affect enforceability. The legal framework for embryo disposition is changing faster than almost any other area of family law, and an agreement that was ironclad when signed may have new vulnerabilities based on statutes or court decisions that did not exist at the time.
