Quick Answer: When an Israeli couple who created embryos through IVF divorces, neither spouse automatically owns the frozen embryos. Israeli law treats them as a category of their own, neither property nor legal person, and both biological contributors must consent before the clinic can thaw, transfer, or destroy them. The 1996 Nachmani Supreme Court ruling established that a court can, in exceptional circumstances, allow one partner to use the embryos over the other's objection, but only where the requesting party has no other realistic path to biological parenthood. The Family Court and Health Ministry regulations both have a say in how these disputes play out.

Israel has the most IVF clinics per capita of any country in the world. The State Health Insurance Law 5754-1994 funds fertility treatment for women under 45 seeking their first two children, with no limit on the number of cycles. The result is that hundreds of thousands of Israelis have undergone IVF, and a significant number of divorcing couples find themselves with frozen embryos stored at clinics across the country.

For foreign nationals who underwent IVF while living in Israel, the legal questions on divorce are concrete and time-sensitive: which country's law applies, what authority does the Israeli Family Court have over embryos stored here, and what happens if one spouse is abroad and the other wants to proceed? The answers come from Israeli statute, Health Ministry regulations, and the case law that has built up since the Nachmani ruling.

Israeli law has never passed a comprehensive statute specifically addressing the ownership of frozen embryos. What exists is a patchwork of Health Ministry regulations, IVF clinic consent forms, and the case law built around the Nachmani decision and its aftermath.

Courts treat frozen embryos as an intermediate category. They are not property in the ordinary sense: neither spouse can sell them, pledge them as collateral, or bequeath them in a will like a bank account. But they are not a legal person with independent rights either. They occupy a position the Supreme Court in Nachmani described as carrying "potential for human life" — a status that demands more protection than a piece of property while stopping short of granting the embryo legal personality.

Two practical consequences follow. The ordinary asset-division rules under the Spouses' Property Relations Law 5733-1973 do not apply to frozen embryos. A Family Court dividing the marital estate cannot allocate embryos to one spouse the way it would allocate a car or a bank account. And because neither spouse can claim absolute ownership, thawing, transferring, or destroying the embryos requires the active consent of both.

In Practice: The Israeli Health Ministry classifies IVF clinics under the Public Health Regulations (In Vitro Fertilization Clinics) 5747-1987. Every licensed clinic must maintain separate written consent records for each IVF cycle, each embryo storage period, and each intended transfer. When a couple's relationship status changes, the clinic is obligated under Ministry Circular 32/2001 to place a hold on the embryos and obtain fresh written consent before any procedure. A clinic that proceeds without updated consent from both parties exposes itself to revocation of its Ministry licence and potential civil liability to the non-consenting spouse.

The Health Ministry maintains a list of licensed IVF clinics through the Director-General's office (Misrad HaBriut). Only licensed clinics may store embryos in Israel. If your embryos are at an unlicensed facility (which occasionally happens when foreign nationals bring material from abroad), the Ministry will not recognise the storage, and a court will have difficulty imposing obligations on that facility.

2. The Nachmani Case: Israel's Landmark Ruling

The 1996 Supreme Court decision in Nachmani v. Nachmani (Civil Appeal 2401/95) remains the foundational authority on frozen embryos in Israeli law, and no embryo dispute on divorce can be understood without it.

The facts: Ruth and Daniel Nachmani married and, after years of fertility difficulties, created frozen embryos at an Israeli clinic. Ruth then had a hysterectomy, making her unable to carry a pregnancy. The couple planned to use a surrogate to carry the embryos to term. Before that happened, the marriage broke down. Daniel began a new relationship with another woman, with whom he eventually had children. He refused to consent to Ruth using the embryos with a surrogate.

Ruth asked the courts to allow her to proceed over Daniel's objection. The case went to the Supreme Court twice. In the first round, the Court ruled for Daniel: he had the right to refuse to become a biological parent against his will. Ruth appealed to a full eleven-justice panel. In a 7-4 decision, the expanded panel reversed course and ruled for Ruth.

The majority reasoning rested on a balancing of rights. Both Ruth and Daniel had a constitutional right to reproductive autonomy under Basic Law: Human Dignity and Liberty. But their circumstances were not equal. Daniel had since fathered biological children through another relationship. Ruth's only path to biological parenthood was the frozen embryos. Given that asymmetry, Daniel's interest in not fathering a child with Ruth did not outweigh Ruth's interest in becoming a biological mother at all.

In Practice: The Nachmani ruling created a narrow exception, not a general rule. Courts applying Nachmani ask two questions: (a) does the party seeking to use the embryos have any other realistic path to biological parenthood? and (b) has the objecting party already achieved biological parenthood through another relationship? Where both answers point the same way — as they did in Nachmani — courts have been willing to override the objection. Where the answers are mixed, or where both parties still have other fertility options, courts consistently refuse to compel use against one partner's wishes. The ruling has been cited in dozens of subsequent Family Court decisions, but the override outcome has been rare.

The minority in Nachmani took the position that the right not to become a parent is as fundamental as the right to become one, and that no court should force parenthood on an unwilling person. That view continues to shape how Family Court judges handle these cases. Most look for a settlement pathway before entertaining any override application.

Every patient who undergoes IVF at a licensed Israeli clinic signs a consent form at each stage of the process: egg retrieval, fertilization, embryo creation, and storage. The standard Ministry of Health consent form (tofes haskama) that clinics have used since the early 2000s includes a clause specifically addressing what happens to the embryos if the couple separates or divorces.

The typical clause gives the couple three options to pre-select: (1) the embryos are destroyed on separation; (2) the embryos remain in storage indefinitely pending further joint agreement; (3) either party may request use of the embryos with a new partner, subject to the other's written consent at that time.

Most couples sign without reading this clause carefully. The result is that many find themselves bound by an option they chose years earlier without thinking through the divorce scenario. Courts treat the signed consent form as a binding agreement between the parties, but retain the power to depart from it where literal enforcement would violate constitutional rights. That is what Nachmani established.

In Practice: Under Health Ministry Circular 32/2001, if the consent form was signed before the divorce was filed or does not specifically address the divorce scenario, the clinic must freeze all activity, notify both partners in writing, and give each party 30 days to provide updated written instructions. If no agreement is reached within 30 days, the clinic refers the matter to the Family Court (Beit Mishpat LaMishpacha) and suspends all embryo activity pending a court order. Annual embryo storage fees during this limbo period — typically NIS 1,200 to NIS 2,000 per year depending on the clinic — continue to accrue and are generally treated as a joint marital expense until the divorce is finalised.

Some clinics, particularly those in the private sector, use their own consent forms that differ from the Ministry standard. Where a private clinic's form does not address divorce at all, the clinic generally defaults to requiring consent from both parties for any action, a conservative approach driven by liability concerns rather than either patient's interests.

4. Health Ministry Storage Regulations and Time Limits

Frozen embryos cannot be stored indefinitely in Israel. The Public Health Regulations (In Vitro Fertilization Clinics) 5747-1987, as amended, set out storage duration rules with direct consequences for divorcing couples.

The default storage period is five years from the date the embryo was created. After five years, the clinic must contact both parties and obtain fresh written consent to continue storage. Where both parties consent, storage can be extended in five-year increments up to a maximum of ten years or the woman's 55th birthday, whichever is earlier. Where the parties disagree about extension (one wants to keep the embryos, the other wants them destroyed), the clinic must again refer to the Family Court.

The storage time limit creates a real deadline in divorce disputes. A couple who created embryos in 2021 and are now divorcing have until approximately 2026 to reach an agreement or obtain a court order before the default five-year storage period expires. Inaction is not an option: a clinic that cannot obtain the required consent or a court order by the storage deadline is entitled to destroy the embryos, subject to giving the parties 90 days' written notice of intended destruction.

In Practice: A divorcing woman at the Sheba Medical Center (Tel HaShomer) fertility clinic who discovered her embryos were approaching the five-year storage limit obtained an emergency interim injunction from the Tel Aviv Family Court within 72 hours, preventing the clinic from acting on the 90-day destruction notice. Under Section 14 of the Courts Law 5744-1984, Family Courts have broad power to issue interim orders preserving the status quo while a main application is pending. This type of emergency application — filed on one day's notice in urgent cases — is the standard tool for preventing embryo destruction while a dispute is being litigated. Court fees for an emergency application run approximately NIS 1,100.

Storage fees during disputed periods are paid by one or both parties depending on the terms of the divorce settlement or interim court order. Where no order addresses fees, clinics typically invoice both parties jointly, and the Execution Office can be used to recover the paying party's share from the other.

The most litigated scenario in Israeli IVF divorce cases is the refusal: one party wants to use or preserve the embryos, the other refuses all consent. There are two distinct refusal situations, and the law treats them differently.

The first is a refusal to allow continued storage while the divorce is pending. Courts treat this as requiring the same Nachmani-style analysis: balancing the reproductive rights of the party who wants to keep the embryos against the reproductive autonomy of the party who wants them destroyed. Where one party's only path to biological parenthood is through those embryos, courts are inclined to preserve them rather than permit destruction, even without the active consent of the other party.

The second situation is a refusal to allow use — that is, the embryos may remain stored, but the party who wants to use them cannot proceed because the other withholds consent for thawing and transfer. This is where Nachmani applies most directly. Israeli courts will not routinely override a refusal to allow use. The standard for overriding requires the applicant to demonstrate that they have no other pathway to biological parenthood and that the other party's refusal is disproportionate given their own reproductive circumstances.

In Practice: In a 2022 Tel Aviv Family Court case (FA 78452-09-21), a woman in her early 40s applied to use shared frozen embryos after her husband refused consent following separation. The court found that she had a diminished ovarian reserve and that the frozen embryos represented her best realistic chance at a biological child, while her husband had already fathered a child with a new partner during the separation. Applying the Nachmani framework, the court granted the application over the husband's objection, ordering the clinic at Ichilov Medical Center to proceed with thawing and transfer upon proof of a valid surrogacy arrangement. The husband appealed; the District Court upheld the Family Court. The case illustrates that Nachmani's override outcome, while rare, is applied where the factual conditions match.

Where neither party's circumstances rise to the Nachmani threshold (both are young, in good health, and could conceive with other partners), Israeli courts consistently refuse to order use against one party's will and instead leave the embryos in storage pending a future agreement.

6. Posthumous Use of Frozen Embryos

A distinct but related issue is posthumous use: can a widow use frozen embryos after her husband's death, or can a widower use a deceased wife's eggs? This is a significant area of Israeli law given the large number of military casualties and the social importance placed on biological continuity.

The Attorney General's 2013 Guidelines on Posthumous Reproduction set out the framework. A widow may petition the Family Court to use frozen embryos created with her late husband's sperm where: (a) the husband had expressed a clear wish during his lifetime that the embryos be used posthumously; or (b) the court finds there is clear evidence he would have consented. The petition must also go through the State Attorney's office, which reviews all posthumous reproduction applications in Israel.

The deceased husband's family (parents, siblings) has the right to be heard in posthumous reproduction proceedings but does not have a veto. The court weighs their position but is not bound by it. Approval rates for posthumous use petitions where the husband left written consent are high; where consent must be inferred from circumstantial evidence, outcomes are less predictable.

In Practice: Under the Ministry of Health Director-General's Circular 23/2011 on posthumous reproduction, an IVF clinic that receives a death certificate for one of its patients must immediately freeze all activity on that patient's samples and notify the surviving partner in writing within five business days. The surviving partner then has six months to file a posthumous reproduction application before the clinic is entitled to apply to the court for destruction instructions. Emergency interim orders to preserve the samples are routinely granted on an ex parte basis (one-party application) by the Family Court pending the main application. Filing fees for the main application run approximately NIS 770 at the Family Court Registry.

Posthumous use from a separated but not yet divorced couple is treated differently from use after divorce. Where the biological parents separated but the divorce was not finalised, courts apply the same Nachmani-style balancing analysis. A finalised divorce terminates the legal relationship between the parties, and posthumous use of a former spouse's material is treated with greater scepticism. Courts expect clear affirmative consent expressed before death in those circumstances.

7. Resolving Embryo Disputes in a Divorce Settlement

The most practical outcome for most couples is to address the frozen embryos directly in the divorce settlement agreement (heskem geirushin). Courts approve settlement agreements and incorporate them into the final divorce order, giving the agreed terms the force of a court order and making them enforceable through the Execution Office.

A well-drafted embryo clause in a settlement agreement should address:

  • Whether the embryos are to be preserved, used, or destroyed, and the timeline for any action
  • Who bears the ongoing storage fees during any period of continued storage
  • Whether either party retains the right to use the embryos in the future with a different partner, and if so under what conditions
  • What happens to the embryos if one party dies before they are used
  • Which clinic holds them, how they are transferred if either party moves, and what notification obligations apply
In Practice: Most Israeli family law attorneys recommend resolving the embryo question at the same time as the financial settlement, before the divorce is finalised. Once the divorce order is issued and the parties go their separate ways, reaching a post-divorce agreement about embryos is significantly harder: the emotional stakes are higher and the legal relationship between the parties has ended. In mediation-based divorces, the mandatory family dispute resolution process under Section 79A of the Courts Law 5744-1984 (run through the Ministry of Justice's Family Mediation Service) includes the option of a dedicated session on reproductive materials. Bringing a letter from the IVF clinic confirming the number and status of stored embryos to the first mediation session allows the parties to discuss specifics rather than abstractions.

Where one party will receive the right to use the embryos under the settlement agreement, the agreement should also specify that the non-using party will execute any additional consent forms the clinic requires before transfer, and that failure to sign those forms within a specified period will be treated as breach of the settlement agreement, giving the other party the right to enforce through the Execution Office or return to court for contempt proceedings.

8. Foreign Nationals and Cross-Border IVF Divorces

Foreign nationals who underwent IVF in Israel and are now divorcing face a jurisdictional question alongside the substantive legal issues. The answer depends on where the embryos are physically stored.

Where the embryos are at a licensed Israeli clinic, the Israeli Family Court has jurisdiction to make orders about their disposition, regardless of the nationality of the biological contributors. The embryos are in Israel, subject to Israeli Health Ministry regulation, and only an Israeli court can direct an Israeli-licensed clinic to act or refrain from acting. Israeli law applies to the substantive dispute because the embryos were created under and stored pursuant to Israeli regulations.

Where one party is abroad and the other is in Israel, the abroad party can be represented by an Israeli attorney acting under a notarized and apostilled power of attorney from their home country. Applications can be filed, hearings attended by video link, and interim orders obtained without either party being physically in the courtroom, a practice that became standard following the courts' pandemic-era transition to remote hearings under the Courts Regulations (Conduct of Hearings via Means of Communication) 5781-2021.

In Practice: A Canadian couple who created embryos at Meir Medical Center (Kfar Saba) during a work posting in Israel subsequently divorced in Canada. The Canadian court's divorce order did not address the Israeli embryos because neither party's attorney was aware of the Health Ministry storage deadline approaching. When the wife discovered the issue, her Israeli attorney filed an emergency application at the Central District Family Court (Petah Tikva) on her behalf with a notarized power of attorney. The court granted a 12-month interim order preserving the embryos and directed both parties to submit their positions on final disposition within 60 days. The process was conducted entirely in writing and by video link. The lesson: if you have embryos stored in Israel, address them explicitly in your divorce settlement. Israeli clinics are not obligated to monitor the status of your foreign divorce proceedings and may proceed with destruction under their standard storage timeline regardless of overseas court orders.

Cross-border enforcement of Israeli court orders about embryos stored in Israel does not raise the same difficulties as cross-border enforcement of financial orders. An Israeli clinic that receives a final court order directing it to act must comply with that order as a matter of Israeli administrative and regulatory law. No foreign enforcement proceeding is needed. The challenge is the reverse: getting an Israeli court to honour a foreign order about embryos stored in Israel, which requires recognition proceedings in the Israeli courts similar to those needed for any foreign judgment.

Frequently Asked Questions

Israeli law does not treat frozen embryos as property that one spouse can own and transfer to the other. Courts treat them as having a unique legal status requiring the consent of both biological contributors before any action. The Nachmani case established that neither spouse has an absolute veto, but overriding one partner's objection requires a compelling showing in court. Most divorcing couples address embryo disposition in their settlement agreement rather than litigating it separately.

Only in exceptional circumstances. The Nachmani Supreme Court ruling allowed a wife to use embryos over her husband's objection because she had undergone a hysterectomy and the embryos were her only path to biological parenthood. Courts treat reproductive autonomy as a constitutional right on both sides. A party seeking to use embryos over an objection must show the Family Court that their circumstances are truly exceptional. That standard is rarely met.

Health Ministry Circular 32/2001 requires every licensed IVF clinic to place a hold on embryos and give both parties 30 days to provide updated instructions if the consent form does not specifically address the divorce scenario. If no agreement is reached within 30 days, the clinic refers the matter to the Family Court and suspends all embryo activity pending a court order. Storage fees continue to accrue during this period and are treated as a joint marital expense.

The default storage limit under the 1987 Health Regulations is five years, extendable with mutual written consent in five-year increments up to ten years or the woman's 55th birthday. After the storage period expires, the clinic gives 90 days' written notice before destruction. Annual storage fees run approximately NIS 1,200 to NIS 2,000. If one party objects to destruction, an emergency interim order from the Family Court can prevent it while the dispute is being resolved.

Yes, if the embryos are physically stored at an Israeli clinic. The Israeli Family Court has jurisdiction over their disposition regardless of the couple's citizenship, and Israeli law applies because the embryos were created under Israeli regulations. A foreign national can be represented by an Israeli attorney with a notarized power of attorney and does not need to be physically present for hearings; video link appearances have been standard since 2021.
