5 Common Prenup Mistakes

Mistakes That Cost Dearly

A prenuptial agreement is a binding legal document. An error in drafting, planning, or process can render it invalid - or worse, create an outcome you never intended. Here are five recurring mistakes.

1. Vague, Non-Specific Language

"All pre-marital assets shall remain with each party" - sounds good, but the court needs to know exactly what you're talking about. If you didn't specify which apartment, which bank account, which pension fund - you've opened the door to dispute.

What to do: List each asset separately, including addresses, account numbers, and estimated values. The more specific the agreement, the stronger it is.

2. Ignoring Future Assets

Many prenups focus only on existing property and forget to address assets that will accumulate in the future: inheritances, gifts, property appreciation, stock options from work. Without clear provisions, future assets fall under the law's default - equal division.

What to do: Define clear principles: inheritances stay private? Gifts from parents belong to the child who received them? Appreciation of a pre-marital apartment - shared or not? See what a prenup includes clause by clause →

3. A One-Sided Agreement

An agreement that protects only one partner may be voided by the court. If the agreement appears extremely "unfair," a judge can determine it was signed under pressure or without genuine understanding. A good agreement protects both sides, even if the protection isn't symmetrical.

What to do: Ensure both parties have representation or at least independent legal advice. An agreement signed with full transparency and counsel for both sides is nearly impossible to void.

4. Never Updating the Agreement

Couples sign an agreement before the wedding and forget about it. Ten years later - there are children, new apartments, businesses, inheritances. The original agreement is no longer relevant, and in case of dissolution, it doesn't protect what truly matters.

What to do: Review the agreement every 3-5 years, or after any significant event (property purchase, inheritance, birth, career change). Update the agreement with a notary when needed.

5. Skipping Notarial Certification

A prenup that isn't legally certified is invalid. Under the Property Relations Law, the agreement must be certified by a notary, family court, or rabbinical court. Couples who draft an agreement themselves or with a lawyer but "forget" to visit a notary essentially have no agreement at all.

What to do: Book a notary appointment immediately after the agreement is ready. Don't postpone. An uncertified agreement is worth the paper it's written on - and these days, not even that.
