Digital Signature on a Prenuptial Agreement — Is It Valid in Israel?

Israel's Electronic Signature Law: What Does It Say?

The Electronic Signature Law 2001 establishes that a secure electronic signature (PKI — Public Key Infrastructure) is legally equivalent to a handwritten signature on any document that Israeli law does not explicitly require to be handwritten.

Why a Prenup Is a Special Case

A prenuptial agreement is not like a rental contract. The Property Relations Between Spouses Law 1973 (§2(a)) requires that a prenuptial agreement have:

1. Both parties' signatures — in writing
2. Judicial approval — by the Family Court or the Rabbinical Court (for Jewish couples)

But in practice — before reaching judicial approval — the signatures must be notarially authenticated. And here lies the constraint: Israeli notaries authenticate physical presence, not electronic signatures.

The Practical Workflow

• Stage 1: Drafting — can be digital
• Stage 2: Both parties review — can be digital
• Stage 3: Internal approval / "understanding" signature — can be digital
• Stage 4: Notary — physical signature authentication — must be physical
• Stage 5: Court submission — can be electronic filing

How Nobiru Leverages Digital Signatures Legally

Nobiru has developed an approach that maximizes what is permitted digitally while requiring physical presence only when there is no alternative.

The Digital Approval Stage (before the notary)

When you reach the signature stage in Nobiru:

1. Signature canvas — each party draws their signature on screen (computer, tablet, or mobile)
2. AES-256-GCM encryption — the signature is encrypted and stored with:

- IP address

- Date and timestamp

- User agent (browser/device)

- Unique fingerprint

1. PDF export — the agreement with both parties' confirmation is ready for printing and notary submission

The Notary Stage (physical)

After digital approval, both parties bring the printed agreement to a notary. The notary:

1. Identifies the parties (national ID)
2. Confirms physical signatures are executed in their presence
3. Signs the notarial certification

What's on the Horizon: Digital Notarization in Israel

Several European countries (Germany, Austria, Estonia) already permit Remote Online Notarization (RON). Israel has not yet enacted equivalent legislation — but the topic is under discussion in the Knesset Constitution, Law and Justice Committee (2025).

Until such legislation passes in Israel, physical signature before a notary remains mandatory for a valid prenuptial agreement.

Conclusion: Digital to the Maximum, Physical to the Minimum

The right approach to a prenuptial agreement in the digital age:

• Everything digital — questionnaire, drafting, review, internal approval
• Only two in-person visits — notary + court (possible in one day)
• No unnecessary travel — Nobiru prepares all documents in advance
