- A prenuptial agreement can be voided in court years after signing — due to flaws that existed at drafting
- Duress, lack of understanding, and child custody clauses are the three most common grounds for invalidation
- Israeli courts will not enforce child custody or child support provisions in prenuptial agreements
- Using an AI or internet template without an attorney review is a genuine legal risk
Why Do Prenuptial Agreements Get Voided in Court?
Many couples assume that once they have signed a prenuptial agreement and received court approval, they are protected. But the Family Court can revisit old agreements and invalidate them if certain conditions are met.
Here are the 6 most common mistakes that lead to invalidation:
Mistake 1: Signing Under Duress or Pressure
What it is: One spouse signed because the other said "sign this or the wedding is off" — a few days before the ceremony.
Why it voids the agreement: The Property Relations Between Spouses Law 1973 requires that signing be free and voluntary (§2). Pressure — especially close to the wedding — is a classic ground for invalidation.
Case law: Israeli courts have voided agreements signed fewer than 30 days before the wedding when one party demonstrated time pressure.
How to avoid it: Sign at least 60–90 days before the event, with each spouse represented by a separate attorney. Preserve communications showing the discussion was calm and balanced.
Mistake 2: One Party Did Not Understand the Agreement
What it is: The agreement was signed, but one spouse did not read Hebrew well, did not read it carefully, or "trusted the other side."
Why it voids the agreement: The court examines whether both parties understood what they signed. Lack of understanding — especially the absence of independent legal advice for one party — is a ground for invalidation.
How to avoid it: Each spouse must meet with a separate attorney. If one spouse is not fluent in Hebrew, a certified translation is required.
Mistake 3: Missing Notary Authentication
What it is: The couple signed the document and even received court approval — but signatures were not authenticated by a notary before submission.
Why it voids the agreement: Without notary authentication, the agreement cannot be submitted for judicial approval at all. An agreement submitted without proper authentication is void from the outset.
Cost: The notary fee is only ₪526 (Notaries Notice 5786-2025, §11(a)). There is no reason to skip this step.

Mistake 4: Including Child Custody Clauses
What it is: The couple wanted to cover "everything" and added clauses like "children will stay with the mother" or "child support will be ₪X per month."
Why it voids the agreement: Israeli courts do not recognize advance arrangements for children. The best interests of the child are assessed at the time of divorce, not before. Including such clauses may:
- Invalidate those specific clauses
- In extreme cases — cast doubt on the validity of the entire agreement
How to avoid it: A prenuptial agreement focuses on assets only. Children — separately.
Mistake 5: Vague or Contradictory Language
What it is: An agreement containing clauses like "all property acquired during the marriage shall remain with the purchaser, except in special circumstances" — without defining what "special circumstances" means.
Why it voids the agreement: Ambiguity in a key clause allows each party to argue a different interpretation. The court will not enforce a clause that lacks a single clear interpretation.
Case law: BA'M 3151/21 (July 2025) reaffirmed: prenuptial agreements must be drafted in clear, explicit language — no general declarations open to interpretation.
How to avoid it: Every clause must include definitions, examples, and a clear dispute resolution mechanism.
Mistake 6: Using an AI or Internet Template Without an Attorney
What it is: Downloading a form from the internet, asking ChatGPT to draft language, and using the result without attorney review.
Why it voids the agreement: AI tools are not current on 2025 case law (BA'M 5620/24, Greenboom v. Ran), cannot identify internal contradictions, and do not know your specific circumstances. An AI-drafted agreement may:
- Contain clauses conflicting with current Israeli law
- Miss critical assets (RSUs, stock grants, inheritances)
- Be voided for "inconsistent drafting" (as established in 2024 case law)
How to avoid it: Use a platform like Nobiru, built on a pre-approved clause library reviewed by a licensed attorney — not generative AI — where an attorney reviews every agreement before signing.

The Bottom Line
A prenuptial agreement is one of the most important legal documents you will ever sign. It is worth investing in it properly from the start — not discovering it is void when it is already too late.
