Landlord not returning your deposit: what to do next

Your tenancy ended. You handed over the keys. Weeks passed and either the landlord has gone silent, returned only part of your deposit, or offered no explanation at all.

This guide covers the exact steps to take – starting with the demand letter that resolves most Dutch deposit disputes before they reach a courtroom.

1. How long does a landlord legally have to return your deposit?

Dutch law does not set a single fixed deadline, but the standard that courts and tenants’ organisations apply is 14 days after the end of the tenancy for undisputed amounts. If the landlord claims deductions, they must specify those in writing – a vague reference to “cleaning” or “damage” is not enough.

In practice, most rental contracts state a deadline explicitly. Check yours first. If the contract is silent, the generally accepted expectation is within one month of the tenancy ending and the keys being returned.

Once that window has passed without a full return or a written, itemised explanation, the landlord is in default – and you have grounds to act.

2. Step 1: Send a formal demand letter (aanmaning)

The demand letter – aanmaning or ingebrekestelling in Dutch – is not optional paperwork. It is the legal trigger that:

• Puts the landlord formally in default (verzuim)
• Starts the clock on statutory interest (wettelijke rente) accruing on the withheld amount
• Creates the paper trail you need if the dispute goes to court

How to send it

Send the letter by registered mail (aangetekende post) to the landlord’s address. Keep your proof of postage. You can also send a copy by email, but email alone is not sufficient – registered mail creates the legal proof of receipt.

If the landlord is an agency rather than an individual, address it to the agency’s registered address. You can find this on the rental contract or via the Dutch Chamber of Commerce (KVK) register at kvk.nl.

3. What if the landlord doesn’t respond to the demand letter?

Most landlords pay up at this point. A formal registered letter makes clear that the tenant knows their rights and is prepared to go further – and a court case is expensive and time-consuming for the landlord too.

If there is no response by the deadline, you have three routes:

1. Route 1: Kantonrechter (subdistrict court) – For deposit disputes under €25,000 – which covers almost all rental deposit cases – you can file a claim at the kantonrechter without hiring a lawyer. Court fees (griffierecht) apply and are currently around €90-€125 for individuals. The court process is conducted in Dutch, so if you are not fluent you will want support with the written submissions.
2. Route 2: Specialist lawyer – demand letter with legal weight – A demand letter from a lawyer carries significantly more weight than one from the tenant alone. In many cases, a single lawyer letter resolves disputes that have been ignored for months.
3. Route 3: Mediation – For some disputes – particularly where there is a genuine disagreement about the extent of damage – mediation can resolve matters faster and more cheaply than court. This is less common for straightforward non-return cases.

4. What if the landlord claims deductions but won’t itemise them?

A landlord cannot simply keep part of your deposit with a general claim that the property needed “cleaning” or “repainting.” Under Dutch law, any deduction must be:

• Specific – which rooms, which items, what was done
• Evidenced – inspection reports, contractor invoices, photographs
• Proportionate – the cost must reflect the actual damage, not a general renovation of the property

If your landlord provides a list of deductions without evidence, respond in writing disputing each deduction and requesting the underlying documentation. Give them 14 days to produce it. If they cannot, those deductions are legally unsupported and you can demand the amounts back.

5. Special situation: You have already left the Netherlands

This does not affect your rights. Dutch law applies to the rental property regardless of where you are living now. A deposit dispute can be pursued entirely remotely – through a lawyer who handles the communication, correspondence, and if necessary the court process on your behalf.

The fact that you have left is often exactly why the landlord has not returned the deposit. Many landlords assume that an expat who has moved on will not take action. This assumption is wrong, and a lawyer letter from a Dutch address tends to change the calculation quickly.

6. Does my landlord owe me interest on top of the withheld deposit?

Once a landlord is in formal default – which the demand letter establishes – statutory interest (wettelijke rente) begins accruing on the withheld amount. The rate is set annually and applied from the date of default. On a deposit of €1,500 held for 6 months, the interest is modest in absolute terms, but it is a legitimate part of any legal claim.

7. When does this become a lawyer matter?

Send the demand letter yourself first – it costs nothing and resolves the majority of straightforward non-return cases. Involve a lawyer when:

• The landlord does not respond to your demand letter within the deadline
• The landlord responds with disputed deductions and no supporting evidence
• The amounts involved make a court route proportionate (as a rough guide, disputes above €500 are generally worth pursuing legally)
• You have already left the Netherlands and need someone to act on your behalf
• You are on a low income and may qualify for subsidised legal aid (toevoeging), which can significantly reduce your costs
