Your landlord demands a contractual penalty: which defence fits?

First identify the complete penalty claim

Ask for the clause relied on, the version of the general conditions and the complete calculation. What conduct allegedly triggered the penalty, on which days and at what daily rate or maximum? A demand giving only a total does not show whether the calculation fits the contract. Retain attachments and messages mentioning a different reason or period as well.

Record three questions separately: did you breach the stated obligation, does the clause make that conduct subject to a penalty, and may the term lawfully be applied? You can dispute the alleged breach and have validity assessed too. The tenancy agreement guide helps locate the documents; this guide concerns responding to an actual penalty demand, rather than signing a new agreement.

Investigate who acts professionally and who acts as a consumer

European protection against unfair terms may apply to residential letting between a landlord acting for professional or business purposes and a tenant renting privately. The Dutch Supreme Court confirmed this in 2016. Legal form or a private individual’s name on the letterhead does not decide the matter alone. Ask how the letting activities are actually organised and have applicability examined with the contract.

A standard clause not individually negotiated requires a different assessment from a genuinely individually agreed term. A signature or selection between standard forms alone does not prove substantive negotiation. Preserve drafts and amendments. Outside the consumer regime, other statutory defences may remain relevant; do not conclude that every penalty is valid as soon as one European condition is absent.

Assess the wording and combined sanctions, not only today’s demand

Read whether damages, surrender of profits, interest or another penalty may also be claimed for the same breach. Record separately which amounts the wording permits to accumulate. The unfairness assessment concerns the contractual arrangement and circumstances at conclusion, not merely the more moderate invoice the landlord sends today.

The 2026 Rotterdam judgment specifically examined the combined effect of subletting income, a penalty and additional damages. Those particular terms did not stand. That is not a rule prohibiting every subletting restriction or contractual penalty. Identify wording in your agreement posing similar or different risks and have its relationship with statutory consequences assessed. Comparing only the amount from another case does not answer that question.

Distinguish disapplying a term from reducing a penalty

If a penalty term within the consumer directive is unfair, the court must not save it simply by choosing a more reasonable penalty amount. The Court of Justice explains that the term must remain inapplicable to the consumer. This differs from seeking reduction of an otherwise applicable penalty. Have both questions considered in the proper order.

Reduction is subject to a restrained test: the Dutch Supreme Court refers to an excessive and therefore unacceptable result and several relevant circumstances. That judgment concerned commercial premises, not a universal amount for residential tenancies. A high ratio to the damage does not decide everything alone. If reduction is requested in the alternative, ask an adviser to explain that this does not inadvertently acknowledge the term’s validity or calculation.

Prepare a factual defence for each alleged breach

Compare the alleged conduct with what actually happened. A payment penalty requires rental periods, bank evidence and any payment arrangements received. Alleged subletting raises questions about use, permission and actual occupation. Late handover also requires assessment of the legal end date. Do not use one general account for different accusations covering different periods.

Ask what evidence the landlord uses and respond to specific passages. You may request clarification of an unclear photograph or an unidentified resident’s report, but do not deny something already shown by original messages. Separate accepted facts from disputed conclusions. The subletting guide or handover guide may clarify the relevant obligation; assessment of the penalty remains a separate step.

Monitor rent and other demands throughout the penalty dispute

An invalid penalty does not eliminate actual rent arrears or mean that a breach cannot have another consequence. In Amsterdam 2026:6716, the penalty was refused while payment, dissolution and eviction were granted separately. The result depended on the specific claims and procedural position. Read which other demands appear in your notice or summons.

Continue meeting undisputed obligations and ask how payments can be allocated clearly. Do not set off a penalty demand against future rent on your own initiative. A summons also requires a timely substantive response to other claims. Confidence that the court examines consumer law is not a practical reason to ignore legal correspondence or leave evidence at home.

Give your response a clear request and sound supporting material

State which penalty you dispute and why: no breach, incorrect period, absent legal basis, unfair term or a separate reduction issue. Request complete conditions and a breakdown if missing. Preserve the sent response and receipt details. A letter does not need a string of legal labels when it remains unclear which factual passage each objection addresses.

Have a settlement or payment arrangement assessed before acknowledging the entire debt. Does it waive only the penalty, or settle rent, deposit and other claims as well? Ask how any penalty already paid will be handled; repayment does not automatically follow from an oral assurance about future penalties. The appropriate next step depends on payment, evidence and any ongoing proceedings.

Make the adviser’s assignment concrete

Provide the contract, conditions, demand, calculation, payment evidence and main counter-evidence with a short index. Ask first for applicability and validity to be assessed, then the factual calculation and desired procedural response. Discuss costs, availability and who monitors the formal deadline. An intake or insurance notification does not confirm that someone is already filing a defence for you.

Use the file preparation tool for document names and open questions, and discuss legal assistance where a large claim or loss of housing threatens. The aim is a substantiated response to this particular contractual penalty. Preparation does not promise complete refusal, a fixed discount or free proceedings; it prevents payment, negotiation and legal defence being treated as the same choice without investigation.

• Preserve the complete penalty clause and applicable conditions.
• Recalculate conduct, period, amount and maximum.
• Investigate consumer scope and genuine negotiation.
• Record all potentially cumulative sanctions.
• Separate the penalty from rent, termination and other demands.
• Agree the response, costs and formal responsibilities.
