Quick Answer: Israeli law explicitly recognizes mutual wills (tzavaot hadaadiot, צוואות הדדיות) under Section 8A of the Succession Law 1965. When spouses create wills that are conditionally linked — whether in one document or two documents that explicitly reference each other — the surviving spouse faces a key restriction: they cannot revoke their portion of the mutual will after the first spouse dies without first returning all benefits received from the deceased's estate. Before the first death, either spouse may revoke freely on proper notice. Understanding this framework is critical for diaspora couples and foreign nationals holding Israeli assets who want their estate plan to work as intended across generations.

Many diaspora couples with Israeli apartments, bank accounts, or Israeli pension savings go through the same planning logic: "We each want the other to inherit everything if one of us dies first. When we're both gone, it all passes to the children." The thinking is entirely sound. But translating that intention into two ordinary Israeli wills — each mirroring the other but legally independent — creates a gap that Israeli law explicitly addressed in 1992: an ordinary will can be revoked or changed at any time, and the surviving spouse owes no legal duty to honor what the two had planned together.

Section 8A of the Succession Law 1965 was introduced precisely to close that gap. It gives spouses a recognized structure for tying their testamentary intentions together, making it difficult for the survivor to quietly redirect assets after the other has died. This guide explains how the framework works, what its practical limits are, and what foreign nationals need to know before executing any wills touching Israeli property.

1. What Are Mutual Wills?

A mutual will — tzavaa hadaadiot in Hebrew — is a testamentary arrangement in which two people, almost always spouses, make wills whose content is conditionally tied to each other. The wills may be mirror images (each leaving everything to the other, then to the children) or complementary (one spouse's will grants the other a life interest in the apartment; the other spouse's will agrees to leave the apartment to the children on their own death).

Before 1992, mutual wills had no special status in Israeli law. Two people could coordinate their wills, but each retained the full unilateral right to revoke at any time. If the first spouse died and the survivor inherited the apartment, nothing legally prevented the survivor from rewriting their own will the following year to cut the children out entirely, or to benefit a new partner after remarrying. The 1992 amendment — Amendment No. 7 to the Succession Law — created the current regime under Section 8A, giving mutual wills binding effect in a carefully defined way.

A few things to understand before going further. Mutual wills must be made by spouses or recognized life partners — the concept does not extend to friends, siblings, or business partners. They may take the form of a single joint document or two separate documents that explicitly cross-reference each other. The special Section 8A rules apply only when the documents clearly state the wills were made in reliance on each other. Similarity of language is not enough. A will that merely uses the same structure or bequests as another person's will is not a mutual will under Israeli law.

In Practice: A standard drafting phrase that creates a mutual will under Section 8A reads: "This will is made in reliance on and is contingent upon the simultaneous will of my spouse, [full name], dated [date], registered with the Inheritance Registrar under reference number [number]." Without that express language, two matching wills remain two legally independent ordinary wills — each fully revocable without consequence or notice to the other spouse.

Section 8A was inserted into the Succession Law 5725-1965 by Amendment No. 7, enacted by the Knesset in 1992 and published in Sefer HaChukim 1388. It works in three layers.

Definition (Section 8A(a)): Mutual wills are wills made by two persons either in a single document or in separate documents, where each will states that it was made in reliance on the other. Both the joint-document form and the separate-linked-documents form receive identical legal treatment once the mutual-reliance language is present.

Pre-death revocation right (Section 8A(b)): While both spouses are alive, either may revoke their mutual will at any time. To exercise this right, they must deliver written notice to the other spouse and to the Inheritance Registrar (Rasham HaYerushoth) at the Ministry of Justice. Once the other spouse receives the revocation notice, the entire mutual arrangement dissolves. The second spouse's will does not automatically become void — it may remain a valid ordinary will if it independently meets the standard formal requirements — but it loses its mutual-will status and can now be revoked freely.

Post-death restriction (Sections 8A(c) and (d)): After the first spouse dies, the surviving spouse can no longer freely revoke their portion of the mutual arrangement. If they wish to do so, they must either refuse to accept the benefits from the deceased's estate or return those benefits. This is the provision that gives the mutual will its practical force. It is also the provision most commonly misunderstood — or simply not disclosed — in legal arrangements handled without Israeli legal oversight.

In Practice: The Inheritance Registrar (Rasham HaYerushoth) operates as part of the Ministry of Justice's Courts Administration directorate. District offices with inheritance jurisdiction are located in Jerusalem, Tel Aviv, Haifa, Beer Sheva, and Nazareth. Registering a will with the Registrar costs approximately NIS 183 under the 2025 court fee schedule (Courts Regulations — Fees, 5774-2014). The registry is sealed during the testator's lifetime; the content is disclosed only upon presentation of a death certificate and a formal application. Registration is optional but provides a contemporaneous evidentiary record of the will's existence and its mutual-will status.

3. The Critical Restriction: What Happens After the First Spouse Dies

This is what catches people off guard. After the first spouse dies, the surviving spouse does not simply inherit and then retain full testamentary freedom. Section 8A(c) creates a fork in the road at the moment of inheritance.

The survivor faces a choice:

  • Accept the inheritance under the deceased's will, in which case they become bound by their own half of the mutual arrangement. Their own will is now effectively locked. They cannot redirect the assets covered by the mutual plan without giving back what they received.
  • Renounce the inheritance under the deceased's will, in which case they are released from their own half of the mutual arrangement. Their own will reverts to an ordinary revocable will, and they regain full testamentary freedom — but at the cost of losing everything the deceased left them.

The practical consequence: once the survivor accepts the apartment, the bank account, or the pension savings left to them under the mutual arrangement, they are bound. They cannot later decide to leave everything to a new partner or disinherit the children from the first relationship. If they want that freedom, they must give back what they received — which is usually impractical or impossible after assets have been sold, spent, or transferred.

One narrow exception exists. Section 8A(d) gives the Family Court authority to release the surviving spouse from the restriction if circumstances have changed so materially since the wills were executed that holding the survivor to the arrangement would be unjust. Documented examples include the death of a named heir, a complete estrangement from a beneficiary, or significant changes in the nature of the estate assets. The threshold for court intervention is high, and such applications are typically contested proceedings that can take 12 months or more to resolve before the Family Court.

In Practice: Couples in blended-family situations — where each spouse has children from a prior relationship and Israeli real estate is involved — face the highest practical risk under this provision. If the mutual will gives the survivor a life interest in the apartment, and the remainder then passes to the deceased's children from the first marriage, the survivor cannot redirect the apartment to their own children or a new partner without renouncing the inheritance and losing the life interest entirely. This is exactly the scenario Section 8A was designed to protect, but it also means the survivor's position must be carefully drafted to avoid unintended hardship.

4. How to Revoke a Mutual Will

Revocation procedures differ materially depending on whether both spouses are still alive or whether the first has already died.

Before the first death: Either spouse may revoke at any time by completing three steps:

  1. Preparing a written revocation notice that identifies the mutual will by date and registration number (if registered).
  2. Serving that notice on the other spouse personally or by registered post to their known address.
  3. Filing a copy of the notice with the Inheritance Registrar at the relevant district office of the Ministry of Justice.

Upon receipt of the notice by the other spouse, the mutual arrangement is dissolved. Both parties are free to make new, independent wills. The earlier mutual wills do not automatically continue as ordinary wills — they should be formally replaced or expressly revoked to avoid ambiguity during probate.

After the first death: Revocation is only practically possible by renouncing the inheritance. The surviving spouse files a renunciation notice (haratza al yerusha) with the Inheritance Registrar within the statutory time limit — under Section 6(b) of the Succession Law, an heir generally has up to 7 years from the date of death to formally claim or renounce, though prompt action is strongly advisable to prevent complications with asset management or estate debts. Once the renunciation is formally recorded, the survivor's will reverts to ordinary revocable status.

In Practice: A surviving spouse who changes their mind a decade after the first death — long after the inherited apartment has been sold and the proceeds spent — cannot practically renounce. Courts have consistently declined equitable relief in such cases because the benefits are no longer capable of return. The realistic window for reconsidering the arrangement is in the first months after bereavement, before assets are transferred, liquidated, or consumed. Couples who anticipate that circumstances might shift — significant age gaps, blended families, health conditions — should address post-death revocation mechanics with an Israeli attorney at the drafting stage, not years later.

5. Drafting Requirements and Registration

A mutual will must first satisfy the general validity requirements for wills under the Succession Law. Israeli law recognizes four types of will, and all four are equally available for mutual arrangements:

  • Handwritten will (tzavaa bichtav yad): Written, dated, and signed entirely by hand by the testator. No witnesses are required, but no typed, printed, or dictated elements are permitted. If the will contains even one typewritten word, it fails as a handwritten will.
  • Witnessed will (tzavaa beidim): Typed or handwritten, signed by the testator in the presence of two witnesses who are not beneficiaries under that will. The witnesses must sign on the same occasion as the testator and must be adults of full legal capacity.
  • Notarial will (tzavaa bifnei notar): Declared and authenticated before a licensed Israeli notary. Provides the highest evidentiary standard and is least vulnerable to challenges based on capacity, duress, or undue influence.
  • Oral will (tzavaa befeh): Available only in extremis — when the testator believes they are facing imminent death. The oral declaration must be witnessed by two adults and reduced to writing within 30 days. Rarely used and more difficult to enforce.

For mutual wills specifically, the notarial form is strongly recommended. It creates an objective contemporaneous record — maintained by a licensed officer of the Ministry of Justice — that both parties understood the mutual nature of the arrangement, signed voluntarily, and were of full legal capacity at the time. These are precisely the grounds on which mutual wills are most commonly attacked in contested proceedings.

Registration with the Inheritance Registrar is optional, but worth doing. A registered will creates a confirmed record of the will's existence and its mutual-will status under Section 8A, even though the content stays sealed during the testator's lifetime. When a death certificate is submitted to the Registrar's office, staff check the registry and alert the executor or heirs to any registered will on file. It also reduces the risk of a later contradictory will going undetected, since anyone registering a new will must account for the prior registration.

Registration fees: approximately NIS 183 per will under the 2025 Ministry of Justice fee schedule. Notarial fees for drafting and authenticating a mutual will arrangement typically range from NIS 700 to NIS 2,200 per couple, depending on estate complexity and the notary's location. Non-residents may authorize an Israeli attorney to handle registration on their behalf using a notarized power of attorney.

A practical note for couples outside Israel: you do not need to travel to Israel to execute a witnessed or notarial will. Under Section 83 of the Succession Law, a will made outside Israel is valid in Israel if it satisfies either Israeli formal requirements or the formal requirements of the country of execution. However, a foreign-executed will intended to function as part of a mutual arrangement under Section 8A must explicitly include the mutual-reliance language described above, and an Israeli-qualified attorney should review it before it is finalized.

In Practice: A couple in New York have their US estate attorney draft mirror wills for their Tel Aviv apartment. Each will states: "I leave my Israeli apartment to my spouse." The wills are validly executed under New York law and are formally valid in Israel under Section 83 of the Succession Law. But because neither will contains an explicit statement that it was made in reliance on the other, and neither is registered with the Israeli Inheritance Registrar, the wills fall outside the Section 8A mutual-will framework. The survivor retains full testamentary freedom after the first spouse dies. Involving an Israeli attorney — even just for a review and a supplementary Israeli codicil — is the only way to close this gap reliably.

6. Practical Scenarios for Foreign Nationals

The mutual will framework raises specific planning questions for diaspora and non-resident families holding Israeli assets. Here are three situations that come up regularly in practice.

Scenario A — Diaspora couple, single Israeli apartment: A British-Israeli couple owns a Tel Aviv apartment purchased for approximately NIS 2.4 million. They want the survivor to continue living there, and on the second death, the apartment to pass equally to their two children. A mutual will granting the survivor a life interest (zchut shimush) in the apartment, with the remainder distributing to the children on the second death, is the appropriate tool. Without it, the survivor could sell the apartment or leave it to a new partner with no legal constraint.

Scenario B — Mixed-nationality couple, non-Jewish spouse: An Israeli husband and his German wife want their Israeli assets to pass between them first and then to the wife's adult children from a prior marriage. Israeli civil inheritance law applies to Israeli real estate regardless of the nationality, religion, or residency of the heirs. Section 8A contains no religious qualification. The Rabbinical Court has no jurisdiction over inheritance matters — these fall entirely under the civil Succession Law and the Family Court system. The mutual will is equally available and equally effective for this couple.

Scenario C — Later-in-life marriage, blended family: A widowed Israeli man, age 72, remarries a Canadian woman, age 64. Each has adult children from their first marriages. They jointly own a Haifa apartment valued at approximately NIS 1.8 million. Both want the other to live in the apartment if one of them dies, but each wants their own children — not the stepchildren — to inherit the apartment on the second death. A mutual will with a life interest for the survivor and a split remainder (his children get his share, her children get her share) is exactly what Section 8A accommodates — but the arrangement must spell out precisely what happens to each half-share on the second death to avoid a contested estate between two sets of adult stepchildren.

What non-residents commonly skip across all three situations is Israeli legal review of whatever wills they already have. A will that is properly executed in the UK, US, Germany, or Canada is not automatically structured to trigger Section 8A protections. Nor does a standard foreign estate plan typically account for the betterment tax consequences on the apartment, or the Israeli probate process the survivor or children will need to navigate.

In Practice: The Inheritance Registrar processes mutual-will probate applications at the district office corresponding to the deceased's last place of residence in Israel, or for non-residents, at the district where the largest Israeli asset is located. For uncontested applications where the mutual will is registered, properly executed, and accompanied by a death certificate bearing a valid apostille under the 1961 Hague Convention, processing time at the Tel Aviv and Haifa offices is typically 3 to 5 months from submission. Jerusalem handles the majority of contested mutual-will applications and estate disputes involving non-resident decedents; those proceedings before the Family Court commonly run 12 to 24 months. Applications involving assets in multiple countries require parallel probate proceedings in each jurisdiction — Israeli counsel should coordinate with foreign estate attorneys to prevent conflicting court orders from different jurisdictions.
