Opting Out of the Jointness Presumption

What Is "Opting Out of the Jointness Presumption"?

Opting out of the jointness presumption (ביטול חזקת השיתוף) means using a prenuptial agreement to override Israel's default rule that assets accumulated during marriage belong equally to both spouses. Without a valid prenup, Israeli law presumes sharing — and everything built up during the marriage gets split 50/50 on divorce.

Why This Matters More Than Ever After 2025

A landmark Israeli Supreme Court ruling (BA'M 5620/24, June 2025) expanded the jointness presumption significantly: assets accumulated before the marriage can now be drawn into the shared pool if the couple built a joint life together over the years. That apartment you bought at 28, before you even met your partner, may be treated as marital property in divorce proceedings.

The specific legal mechanism that cancels this presumption is the property separation clause (סעיף הפרדה רכושית) — it explicitly names which assets belong to each spouse individually and blocks the presumption from applying to them.

Who Needs This Most?

• Business owners — company value built before marriage can grow during it and get classified as joint property
• Property holders — real estate, land, or inheritances received before the wedding
• Second marriages — assets from a prior life need clear contractual protection
• Equity holders — RSUs, stock options, or vesting plans that started before marriage and mature after

What Does Opting Out Actually Look Like?

A prenup with a property separation clause doesn't mean "everything is mine and you get nothing." It means you choose — deliberately and together — what stays separate and what becomes joint. A well-drafted clause will:

• Name specific assets by registration number, company name, or account
• Exclude appreciation in value of pre-marriage assets
• Cover future income derived from pre-marriage holdings

The Nobiru Process

Nobiru's 7-step questionnaire builds a full prenup from 37 attorney-pre-approved clauses for ₪599 per couple. An optional ₪499 add-on brings in a personal lawyer review of your specific agreement. After digital signing, the couple visits a notary — ₪526 under Notaries Notice 5786-2025 §11(a) — who is the one who confers legal validity under Section 2 of the Property Relations Law.
