Does an invalid clause void the whole contract in the Netherlands?

Not necessarily. Under BW 3:41 only the void part fails, unless that part is so connected to the rest that the contract cannot reasonably stand without it.

What is conversion (conversie)?

Under BW 3:42 a void act may be converted into a valid one with equivalent effect that matches the parties' presumed intention, which is useful when a clause is struck down.

When does severance fail and the whole contract become void?

Under BW 3:41 severance fails when the void provision is so central to the bargain that neither party would have contracted without it, and courts assess this based on the connection between the struck clause and the rest of the agreement.

Should the parties agree in advance how to replace a void clause?

Yes. A good severability clause includes a renegotiation or automatic-replacement mechanism, directing the parties to agree on a valid provision that reflects the economic intent of the struck clause as closely as possible.

Is a severability clause needed if Dutch law already provides for partial nullity?

It is still useful. A contractual clause guides the parties on replacement and confirms intent to preserve the rest of the contract, which supplements and strengthens the statutory default under BW 3:41.

Severability Clause

Keeps the rest of the contract valid if one provision is held unenforceable, and provides for its replacement.

Qué es

A severability clause provides that if a court finds one provision invalid or unenforceable, the remaining provisions stay in force, and the void term is replaced by a valid one closest to the parties' intent. Dutch law addresses this through partial nullity under BW 3:41.

Por qué importa

It prevents one defective clause from sinking the whole contract. Combined with a conversion (conversie) mechanism, it keeps the deal alive and steers any replacement term toward what the parties originally intended.

Cómo aplicarla

State that invalidity of one clause does not affect the others.
Require the parties to replace a void clause with a valid, economically equivalent one.
Align it with BW 3:41 partial nullity and conversion under BW 3:42.
Recognise that severance fails if the void term is essential to the bargain.

Consejos de negociación

• Add a duty to renegotiate in good faith to replace the struck-out provision.
• Identify any clause so fundamental that its invalidity should end the contract.

Errores frecuentes

• Assuming severance always works; BW 3:41 makes it depend on the contract's coherence.
• No replacement mechanism, leaving a gap where the void clause stood.
