Israeli Marital Property Agreements for French Couples

A couple marries in Paris under a contrat de séparation de biens, the separate-property regime their notaire recommended, and years later buys a holiday apartment in Netanya in both their names. Then something changes: a divorce, or the death of one of them. The surviving spouse, or the children from an earlier marriage, arrive at an Israeli lawyer's office holding the French contract and assuming it settles who gets the apartment. Sometimes it does. Often it does nothing at all, and the reason is not that the French document is defective. It is that Israeli law only reaches it in a particular way, and only if someone knows to ask.

French families are unusually exposed to this gap, because so many own property in Israel while keeping their lives, their marriage regime, and their advisers in France. The document that protects them at home does not travel automatically. Understanding how Israel treats a marriage contract, and when an Israeli marital property agreement is worth signing instead, is what keeps a Netanya apartment from becoming the subject the couple thought they had already resolved.

What a Mamon Agreement Is and Why It Needs Approval

Israel has its own instrument for arranging property between spouses, and it is more formal than a signature at the bottom of a contract.

A marital property agreement, heskem mamon, is a written agreement between spouses setting out who owns what during the marriage and how property is divided if it ends. Section 1 of the Spouses (Property Relations) Law 5733-1973 requires it to be in writing, and any change to it as well. But writing alone does not make it enforceable. Section 2 requires the agreement to be confirmed, and the confirming body, a notary before the marriage or the Family Court after it, must satisfy itself that both spouses signed of their own free will and understood what they were giving up. That confirmation is not a rubber stamp. It is the step that turns a private document into an agreement an Israeli court will apply.

This matters for a French couple in a specific way. A French contrat de mariage is confirmed by a French notaire under French formalities, which are not the Israeli ones. Whether it will be recognised in Israel is a separate question from whether it was validly made in France, and the two do not always give the same answer.

In Practice: Section 2 of the Spouses (Property Relations) Law 5733-1973 makes a heskem mamon enforceable only once confirmed, before marriage by an Israeli notary and after marriage by the Family Court. A notary's confirmation carries a fixed fee under the Notaries Fees Regulations 1977, where the first page runs NIS 251, while a Family Court approval hearing is usually listed within 6 to 12 weeks of filing. Skip the confirmation and the paper you signed may bind you as an ordinary contract in narrow circumstances, but it will not do the work of a marital property agreement when it matters most.

The Default Regime If You Do Nothing

Couples who never sign anything are not left without rules. Israel supplies a default, and it is worth knowing what it produces.

Section 3 of the 1973 Law provides that spouses without a property agreement are treated as having agreed to resource balancing (izun mashabim). Under Section 5, when the marriage ends by divorce or death, each spouse is entitled to half the value of the assets the couple accumulated. This is a claim to value, not automatic co-ownership; during the marriage each spouse keeps their own property, and the balancing is settled only at the end. Section 5 also carves out what is not shared: assets owned before the marriage, and gifts and inheritances received during it, stay with the spouse they belong to, along with pension and severance rights under a separate calculation.

For a couple whose Israeli apartment was bought with joint savings during the marriage, the default and their expectations may line up. For a couple where one spouse brought family money, or inherited the funds, the default can divide something they assumed was protected, unless the exclusion is respected and, ideally, documented.

How Israel Treats a French Marriage Contract

This is the pivot on which most French cases turn, and it has two stages that people collapse into one.

Section 15 of the 1973 Law is a conflict-of-laws rule. It provides that property relations between spouses are governed by the law of their domicile when the marriage was solemnised, with a limited power to vary that by agreement under the law of their domicile when the agreement was made. For a couple who married in France and lived there, French law characterises the Netanya apartment, and the Israeli default of resource balancing simply does not apply to them. Their French regime, community or separation, is what governs. On its face, that is good news for a couple who chose séparation de biens precisely to keep their property apart.

The difficulty is procedural. Foreign law in Israel is a question of fact, not something a judge is presumed to know. Nobody applies Section 15 unless a party raises it and proves the content of French law, usually through an affidavit from a French lawyer, apostilled and translated. The Inheritance Registrar issuing a succession order works from the Succession Law 1965 and the population registry, not from French matrimonial doctrine, and will not read a French contract at all. If the point is not taken in time, the Israeli default governs by inertia, and the French contract that would have settled everything is never looked at. Our guide to French forced heirship against Israeli testation works through the related succession side of the same Franco-Israeli picture.

In Practice: Under Section 15 of the Spouses (Property Relations) Law 5733-1973 a French couple's property relations follow French law, and under Section 5 balancing runs first on death, so on a Netanya flat worth NIS 4,000,000 the surviving spouse's marital claim is settled before the Succession Law 1965 divides anything. Proving the content of French law needs an expert affidavit costing USD 3,000 to 7,000, and the Inheritance Registrar (Rasham HaYerushot) will not apply it unless the point is raised within the objection window stated in the publication, which is not less than two weeks. Miss that window and foreign law never enters the file.

What Happens on Death, Not Just Divorce

Most couples think of a marriage contract as a divorce document. In Israel its quieter and often larger effect is on death.

Resource balancing under Section 5 is triggered by death as much as by divorce. When one spouse dies, the survivor's balancing entitlement is calculated first and taken off the top of the couple's assets. Only what remains of the deceased's own share becomes the estate, and only that estate passes under the Succession Law 1965, where a surviving spouse also takes a statutory inheritance share. So the survivor can receive twice: once as a marital balancing claim, and again as an heir. For a blended family, French or otherwise, that ordering can leave children from an earlier marriage with far less than the parent intended, and a mamon agreement is one of the few tools that can reshape it in advance.

Signing and Approving the Agreement From Abroad

The mechanics are where good intentions stall, because the confirmation Section 2 demands assumes the couple can reach an Israeli notary or an Israeli court.

Before marriage, the cleaner path, the agreement can be confirmed by an Israeli notary. A couple in France either signs on a visit to Israel, or, if they are Israeli citizens, uses an Israeli consulate that provides notarial services. After marriage, confirmation shifts to the Family Court, and a couple abroad generally arranges this through Israeli counsel, sometimes giving evidence by video where the court permits it. Either way the agreement should be drafted with Section 15 in mind, so that it expressly addresses the Israeli apartment and states which law the couple intends to govern it, rather than leaving an Israeli judge to reconstruct their intentions years later from a French document written for a French purpose. Pairing the agreement with a separate Israeli will, and confirming which law governs the estate, closes the remaining gap; our answer on which law governs a non-resident's Israeli estate explains that second question.

The Assumption That Costs French Families

The recurring error is quiet, and it is almost always the same one.

Common Mistake: A French couple assumes their séparation de biens contract automatically protects the Netanya apartment in an Israeli proceeding. Because foreign law must be pleaded and proven, and nobody raises it, the Israeli default governs by inertia and a succession order issues without the French contract ever being read. Unwinding a granted order under Section 72 of the Succession Law 1965 is far harder and more expensive than raising Section 15 inside the two-week objection window would have been, and by then the apartment may already have been distributed on terms the couple never chose.

Practical Checklist

• Locate your French marriage contract and confirm which regime you married under, because that is what Section 15 will point an Israeli court to.
• Decide whether to rely on the French contract in Israel or to sign a separate Israeli mamon agreement that expressly covers the Netanya property.
• If you sign an Israeli agreement, get it confirmed under Section 2, by a notary before marriage or the Family Court after, or it will not be enforceable as a marital property agreement.
• Keep inheritances and family gifts out of joint accounts and jointly registered property, so the Section 5 exclusion is not lost to commingling.
• Remember that on death the survivor may take both a balancing claim and an inheritance share, and plan a will around that combined effect.
• If a spouse dies, raise the applicable-law point with the Inheritance Registrar inside the objection window rather than after an order is granted.

Speak With an Israeli Attorney

A French marriage contract and an Israeli apartment need to be read together, in advance, so that the document you already have is either made to work in Israel or replaced by one that will. We review the French regime against Section 15, draft and confirm an Israeli mamon agreement where it helps, and make sure the point is raised in time when an estate is opened.
