How do penalty clauses (boetebeding) work under Dutch law?

Dutch term: Boetebeding | Legal basis: Articles 6:91 to 6:94 of the Dutch Civil Code

A penalty clause (boetebeding) under article 6:91 of the Dutch Civil Code stipulates that a specific sum is payable on the occurrence of a defined breach. Unlike in some common-law systems, penalty clauses are valid and enforceable under Dutch law. However, article 6:94 gives Dutch courts the power to moderate (matigen) the penalty if the stipulated amount is manifestly excessive in the circumstances.

The moderation power is exercised regularly by Dutch courts in commercial cases. The court assesses the proportionality of the penalty against the actual damage suffered, the nature and seriousness of the breach, and the overall circumstances. A well-drafted penalty clause with a proportionate amount tied to the commercial logic of the contract is more likely to be enforced in full than a round figure that looks punitive.

Depending on how the clause is drafted, the penalty may replace the creditor's entitlement to damages (a penalty in lieu of damages) or may be payable in addition to damages (a cumulative penalty). The default under article 6:92 is that the penalty replaces damages unless the contract provides otherwise.

Why it matters for international businesses

International contracts under Dutch law should draft penalty clauses with the moderation power in mind. An amount that is clearly disproportionate to the likely damage will be reduced by the court. See our breach of contract litigation page or contact us for drafting or enforcement advice.
