Mutual Wills in Israel: A Guide for Non-Resident Couples

Picture a couple in their sixties who live in London or Toronto but own an apartment in Tel Aviv that has been in the family for decades. They want the same thing most couples want. On the first death, the survivor keeps everything. On the second death, it all goes to their children in equal shares. What worries them is the scenario nobody likes to say out loud: the survivor remarries, makes a new will, and the children from the first marriage end up with nothing.

That worry is exactly what a mutual will is built to solve. Israeli law gives it real teeth, but only if the will is drafted to fit Section 8A of the Succession Law 1965. A will that simply says "we leave everything to each other and then to the children" does not automatically create a binding mutual arrangement. The binding force comes from the structure, and the structure has rules that catch foreign couples by surprise.

This guide explains how mutual wills work in Israel, why they constrain the surviving spouse, and how a couple living outside the country actually signs one without flying in. If you also hold a will drafted at home, read it alongside our guide on the validity of foreign wills in Israel.

What a Mutual Will Actually Is

A mutual will, tzava'a hadadit, is two wills made by spouses who each rely on the promise contained in the other's will. The reliance is the whole point. Each spouse arranges their estate the way they do because the other is doing the same. Section 8A, added to the Succession Law in the 2005 amendment, recognises that reliance and protects it.

You can build a mutual will in one of two ways. It can be a single joint document signed by both spouses, or two separate but matching wills signed on the same occasion. Both are valid. The beneficiary does not have to be the other spouse either. A couple can leave their estates directly to their children and still create a binding mutual will, as long as the reliance between the two testators is genuine.

What separates a mutual will from two ordinary wills that happen to look alike is the restriction on changing your mind. With ordinary wills, either spouse can quietly rewrite their will the day after signing and never mention it. With a mutual will, the law locks the door.

Why It Binds the Surviving Spouse

While both spouses are alive, neither can revoke the mutual will in secret. Section 8A(b)(1) requires a spouse who wants out to give written notice to the other. The effect is deliberately blunt: that notice cancels both wills at once. Nobody gets to keep the benefit of the other's promise while abandoning their own.

After the first spouse dies, the rules tighten further. This is the part foreign couples almost never anticipate. Under Section 8A(b)(2), a surviving spouse who wants to change the arrangement faces two situations:

• If the estate has not yet been distributed, the survivor must first renounce everything left to them under the mutual will. Give up the inheritance, and only then are they free to write a new will.
• If the survivor has already received the inheritance, they must return what they took, or its monetary value, before a new will can stand.

Read those two conditions again and the protective logic becomes obvious. The survivor cannot keep the deceased spouse's half of the apartment and then divert it away from the children. To rewrite the plan, they have to hand back the benefit first. For a couple who fear the "second marriage" scenario, that is the safeguard they are looking for.

In Practice: Under Section 8A(b)(2) of the Succession Law 1965, a surviving spouse who has already inherited under a mutual will must return the inheritance or its value before any later will takes effect. On a Tel Aviv apartment worth NIS 3,000,000, that means the survivor cannot simply re-gift the property to a new partner. The Inheritance Registrar (Rasham HaYerushot) at the Ministry of Justice will register a will execution order based on the mutual will, and a challenge by the original children is heard by the Family Court, a process that runs 12 to 24 months once an objection is filed.

Signing the Will From Outside Israel

None of this requires the couple to be in Israel. A will under the Succession Law is valid if it is signed before two witnesses who are present together, and an Israeli notary can also authenticate the signatures. Couples abroad have three practical routes.

The first is to sign before two witnesses wherever you live, following the witnessed-will format in Section 20 of the Succession Law. The second is to have the signatures authenticated by an Israeli notary, which is straightforward in cities with an Israeli community but harder elsewhere. The third is to sign at an Israeli consulate, where the consular officer holds notarial powers under the Notaries Law 1976.

Whichever route you choose, the document and any supporting paperwork eventually have to satisfy an Israeli court or the Inheritance Registrar. If your marriage certificate, identity documents, or the will itself are in a foreign language, they will need an apostille and a notarised Hebrew translation before anyone in Israel will act on them. Plan the apostille step early, because it is handled by the authority in your own country, not in Israel.

In Practice: A notarised Hebrew translation of a foreign-language will is required before the Inheritance Registrar will issue a will execution order (tzav kiyum tzava'a). The notary fee for confirming a translation is fixed by the Notaries Fees Regulations 1978 at roughly NIS 245 for the first 100 words, rising with length. The application to the Inheritance Registrar itself carries a fee of about NIS 540 plus a newspaper publication fee near NIS 130, and an uncontested order is typically issued within four to six weeks.

Why a Separate Israeli Will Usually Wins

Many non-resident couples already have a mutual or "mirror" will drawn up at home. The instinct is to assume it covers the Israeli apartment too. Sometimes it does, in the sense that it disposes of worldwide assets. The trouble is the friction at execution.

A foreign will has to be probated in Israel through a will execution order, which means translating it, apostilling the supporting documents, and frequently proving the relevant rules of your home country's law to the Israeli court. Even then, an Israeli court applies Section 8A's binding effect only where the will genuinely meets the mutual-will definition, and foreign mirror wills are not always drafted with that section in mind.

A short Israeli will covering only the Israeli asset sidesteps most of that. It is written in Hebrew, fits the Succession Law format, names the Israeli apartment or bank account specifically, and can be executed without first untangling foreign law. Couples who own property in more than one country often keep parallel wills, one per jurisdiction, each careful not to revoke the other. Our guide on a separate Israeli will for non-residents walks through how to coordinate the two so they do not clash.

Where Mutual Wills Go Wrong

The most damaging error is procedural, and it happens after the first death rather than before. A surviving spouse, often acting on advice from a lawyer in their home country who does not know Section 8A, simply writes a new will. They never disclaim the inheritance, never return anything, and assume their later will controls. It does not.

Common Mistake: A surviving spouse changes their mutual will after inheriting without first disclaiming or returning the inheritance, as Section 8A(b)(2) of the Succession Law 1965 demands. The new will is treated as ineffective to the extent it conflicts with the mutual arrangement. When the original children discover this and file an objection with the Family Court, the estate is frozen during litigation that commonly lasts 12 to 24 months and costs NIS 40,000 to NIS 100,000 in combined legal fees before distribution resumes.

A second, quieter mistake is treating a mutual will as set in stone while both spouses are alive. It is not. As long as both are living, the will can be cancelled, but only openly, by written notice that voids both sides at once. Couples sometimes want to update beneficiaries after a child marries or a grandchild is born and panic because they think they are locked in. They are not, provided they act jointly and transparently.

Practical Checklist

• Decide whether your Israeli assets justify a dedicated Israeli will rather than relying on a foreign mirror will
• Confirm the will is drafted to meet Section 8A so the binding mutual effect actually applies
• Choose your signing route in advance: two witnesses, an Israeli notary, or an Israeli consulate
• Apostille and arrange notarised Hebrew translations of your marriage certificate and identity documents early
• Keep any foreign will and any Israeli will consistent, with neither revoking the other
• Tell your children where the originals are held, and keep a scanned copy with your Israeli lawyer

Speak With an Israeli Attorney

A mutual will is one of the few tools that genuinely binds a surviving spouse, but it only works when it is drafted to fit Section 8A and coordinated with any will you hold abroad. We prepare Israeli mutual wills for couples living outside the country, arrange remote signing, and make sure your Israeli and foreign wills do not cancel each other out.
