Quick Answer: Prenuptial agreements (Heskem Mamon) are fully valid in Israel and are increasingly common, particularly for couples with significant pre-existing assets or international connections. They must be approved by the Family Court or Rabbinical Court to be enforceable. They can modify asset division, protect business interests, and address get refusal.

1. Overview

A prenuptial agreement (Heskem Mamon — literally "property agreement") allows a couple to set out their own financial arrangements for marriage and potential divorce, instead of relying on the default rules of the Spouses (Property Relations) Law 1973. In Israel, such agreements are expressly recognised and enforceable when properly executed.

Despite a lingering cultural reluctance to discuss "what if we divorce" before the wedding, prenuptial agreements are increasingly common among sophisticated couples — particularly those with significant pre-existing wealth, business interests, international assets, or children from prior relationships.

Prenuptial agreements in Israel are governed by the Spouses (Property Relations) Law 1973, which expressly allows spouses to enter into a property agreement that departs from the law's default equal-division regime.

The law imposes two key requirements for such an agreement to be valid and enforceable:

  • Written form: The agreement must be in writing.
  • Court approval: The agreement must be approved by a Family Court judge or by the Rabbinical Court (for Jewish couples who choose to use the Rabbinical Court). The court conducts a brief hearing to verify that both parties understood and agreed to the agreement freely.

Without court approval, a property agreement between spouses is not binding as a Heskem Mamon — though it may have contractual effect in other ways, subject to general contract law principles.

3. The Court Approval Process

Obtaining court approval is a straightforward process that takes place before the marriage (for a prenuptial agreement) or at any time during the marriage (for a post-nuptial agreement):

  1. Draft the agreement: An attorney drafts the agreement, reflecting the couple's agreed financial arrangements. Both parties should ideally receive independent legal advice.
  2. File an application: The application for approval is filed with the Family Court (or Rabbinical Court). This is not a contested application — it is an administrative step.
  3. The hearing: The judge meets briefly with both parties (usually together, sometimes separately) to confirm that they understand the agreement, that it is their own free choice, and that they have not been pressured. The hearing is typically very short.
  4. Approval: If satisfied, the judge approves the agreement by court order. The approval order is the crucial document that makes the agreement a valid Heskem Mamon.

The process is private and confidential. The contents of the agreement are not publicly disclosed. The total legal costs are modest compared to the financial protection the agreement provides.

4. What a Prenuptial Agreement Can Address

A Heskem Mamon can address a wide range of financial matters, including:

  • Separation of assets: Specifying that particular assets — a pre-existing business, inherited property, savings, investments — remain the separate property of the owning spouse and are not included in the marital estate on divorce.
  • Different division ratios: Providing for a division other than 50/50 — e.g., reflecting the relative financial contribution of each spouse, or protecting a spouse who has significantly greater pre-marital assets.
  • The family home: Specifying the treatment of the family home on divorce — whether it is sold and proceeds divided, or one spouse has the right to buy out the other.
  • Spousal support: Setting out agreed arrangements for spousal support on divorce, including any waiver or limitation.
  • Business interests: Ring-fencing a business or professional practice from the marital estate, to protect business partners, employees, and continuity.
  • Children from previous relationships: Protecting assets intended to pass to children of a prior relationship.
  • Debt protection: Clarifying that pre-marital debts are the sole responsibility of the indebted spouse.

5. What a Prenuptial Agreement Cannot Cover

A Heskem Mamon cannot override certain mandatory protections:

  • Child support and child custody: Agreements about child support and custody arrangements are not binding — the court always retains the power to determine what is in the children's best interests at the time of divorce.
  • Provisions contrary to public policy: An agreement that is grossly unfair to one party, or that was entered into under duress or with lack of capacity, will not be upheld.
  • Waiver of basic maintenance rights: A complete waiver of the weaker spouse's right to any financial support may be void if it leaves one party destitute.

6. Post-Nuptial Agreements

Couples who are already married can enter into a property agreement at any time during the marriage. Such agreements are subject to the same court approval requirement as prenuptial agreements. Post-nuptial agreements are useful where circumstances have changed — e.g., one spouse inherits significant wealth, starts a business, or the couple wishes to restructure their financial arrangements.

Israeli courts apply a higher level of scrutiny to post-nuptial agreements than to prenuptial ones, as the power dynamics and circumstances of the parties are more complex. Evidence of full financial disclosure and independent legal advice is particularly important.

7. The Get Clause

A provision gaining traction in Israel — borrowed from practice in the diaspora Jewish community — is including a get clause in the property agreement. This clause imposes financial penalties on a spouse who refuses to grant or accept a religious divorce (get) within a reasonable time after the couple decides to divorce.

The get clause is designed to address the power imbalance created by the halachic requirement that the get be given voluntarily. By creating a significant financial consequence for refusal, it incentivises compliance without technically coercing the get itself (which would render it void).

Israeli rabbinical authorities have been cautious about such clauses, and their halachic validity is contested. However, the civil courts have been more receptive, and properly drafted get clauses have been upheld in Israeli civil court proceedings.

8. International Couples

For international couples — where both parties are foreign nationals, or where significant assets are located abroad — a prenuptial agreement should address the following additional issues:

  • Choice of law: Which country's law governs the property arrangements? This is particularly important where the couple may live in different countries at different times, or where assets are in multiple jurisdictions.
  • Jurisdiction clause: Which country's courts will have jurisdiction over financial disputes on divorce?
  • Recognition abroad: An Israeli Heskem Mamon approved by an Israeli court may not automatically be recognised in all foreign jurisdictions. Where assets are held abroad, the agreement may need to be structured to be enforceable in those jurisdictions as well.
  • Coordination with foreign advisors: In cross-border situations, the Israeli family law attorney should work in coordination with legal advisors in the relevant foreign jurisdictions.
