Which letters, and why?
| Letter | Status | Why |
|---|---|---|
| Tenant's notice to end a residential leaseHow to send it | Required by law | The law says a residential lease is ended by registered letter or through a bailiff. That way you can show the landlord received your notice in time.Deadline: Notice equal to the rent payment period, at least one month and at most three months; usually one month. |
| Landlord's notice to end a residential lease | Required by law | The landlord must give notice by registered letter or through a bailiff, state a ground allowed by law and ask the tenant to reply within six weeks whether they agree. Without consent only a court can end the lease.Deadline: At least three months, plus one month per year of tenancy, up to six months. |
| Objection to a rent increase | Recommended | You must tell the landlord in writing before the start date that you do not agree, and not pay the increased rent. A registered letter proves your objection was on time.Deadline: Before the date the increase would take effect (usually 1 July). |
| Landlord's reminder after an unanswered rent increase | Required by law | If the tenant neither objects nor pays the increase, the landlord must send the proposal again by registered mail, with a copy of the original proposal. Without this reminder the increase does not take effect; the tenant then has four months to go to the Huurcommissie.Deadline: Within three months after the proposed start date; the Huurcommissie reads this as: the tenant must receive the letter within those three months. |
| Reclaiming a rental deposit | Recommended | There is no required form, but if the landlord does not repay, a registered letter with a final deadline is the usual step before going to court. It proves you formally put the landlord on notice.Deadline: The landlord must repay within 14 days after the lease ends, or within 30 days when deducting damage or arrears. |
| Notice of defects to the landlord | Recommended | A rent reduction can only start from when you reported the defect, and the Huurcommissie asks for dated proof of that report. A registered letter gives you that proof.Deadline: The landlord usually gets six weeks to repair before you can go to the Huurcommissie. |
| Notice to end a retail or catering premises lease | Required by law | For retail, catering and craft premises the law requires a bailiff or registered letter, with a long notice period. For offices and other business premises this form does not apply and the contract mostly sets how to give notice.Deadline: At least one year, effective at the end of the current lease term (usually after five or ten years). |
| Resignation by an employee | Recommended | The law sets no form, but the government advises resigning in writing and asking for an acknowledgement of receipt. Registered mail helps if the employer does not confirm and the notice period is tight.Deadline: Usually one month, effective at the end of the month, unless the contract says otherwise. |
| Dismissal by the employer | Recommended | An employer can usually only give notice after permission from the UWV or with the employee's written consent, and must then observe the notice period. The notice itself has no fixed form, but a registered letter records the date.Deadline: One to four months, depending on length of service. |
| Summary dismissal for urgent cause | Recommended | The dismissal and the urgent reason must be communicated immediately; there is no fixed form. The employer must later be able to prove when and why it dismissed, so a letter usually follows, often by registered mail.Deadline: Without delay after the urgent reason; the employee has two months to challenge the dismissal in court. |
| Insurance cancellation | Not needed | The law gives you the right to cancel insurance electronically. Do ask for confirmation; registered mail adds little.Deadline: After the first year usually one month's notice; otherwise two months before the end of the policy period. |
| Cancelling a phone, internet or TV contract | Not needed | You may always cancel in writing, including by email or web form, and in the same way you signed up. Ask for confirmation of the cancellation.Deadline: After the fixed term, at most one month's notice. |
| Cancelling a gym or other subscription | Not needed | You may cancel in writing, including by email, and online if you signed up online. A term demanding a stricter form, such as registered mail only, is presumed unfair.Deadline: At most one month's notice after the initial term. |
| Cancelling an energy contract | Not needed | When you switch, the new supplier cancels the old contract for you. Ending a fixed-term contract early may cost an exit fee; the way you cancel does not change that.Deadline: At most one month's notice, as set in the contract. |
| Switching health insurer | Not needed | If you take out a new health policy before 1 January, you usually do not need to cancel anything yourself. Only if you cancel yourself must the cancellation arrive by 31 December.Deadline: Cancel by 31 December; take out the new policy before 1 February, backdated to 1 January. |
| Fourteen-day letter (payment reminder to a consumer) | Recommended | You may only charge a consumer collection costs after a reminder that gives them fourteen days to pay without costs and states those costs. Courts refuse the costs if you cannot prove the letter was received; sending it to the right address is not enough.Deadline: Fourteen days, counted from the day after the letter is received. |
| Formal notice of defaultHow to send it | Recommended | A notice of default must be in writing and give the other party a reasonable period to perform. Only after that can you usually claim damages or end the contract, so you must be able to prove the letter arrived.Deadline: A reasonable deadline that you set in the letter, often 14 days. |
| Disputing a debt or collection claim | Recommended | There is no required form, but if it comes to court it helps to show you disputed the claim on time and with reasons. A registered letter records that. |
| Objection to a tax assessment (Belastingdienst) | Not needed | You can object online and it appears in your overview within one working day. A letter must be signed; by post it counts as on time if sent before the deadline and received within a week.Deadline: Six weeks after the date of the assessment. |
| Appeal against a traffic fine (CJIB) | Not needed | An appeal against a traffic fine goes to the public prosecutor, not to the CJIB, and can be filed online. If you send a letter, registered mail proves you were on time.Deadline: Six weeks; the last date is printed on the fine. You do not have to pay while the appeal is pending. |
| Objection to the municipality (parking fine, local tax, decision) | Recommended | An objection only counts if it arrives within the deadline, or is posted within the deadline and arrives within a week. If the municipality has no online form, a registered letter proves you were on time.Deadline: Six weeks after the date of the decision or assessment. |
| Withdrawal within 14 days (cooling-off period) | Not needed | Any clear statement is valid, and online shops have had to offer a withdrawal button with an instant acknowledgement since June 2026. You must be able to prove you withdrew in time.Deadline: Fourteen days after receiving the goods or concluding a service contract. |
| Claim under the statutory guarantee | Recommended | You must report the defect in good time and give the seller a chance to repair or replace. If the seller refuses, a registered notice of default is the usual next step.Deadline: Reporting within two months of discovery is always on time. |
FAQ
Which letters must go by registered mail in the Netherlands?
A tenant's or landlord's notice ending a residential lease, a notice ending a lease of retail, catering or craft premises, and the landlord's reminder when a tenant does not respond to a rent increase. For the notices, the law also accepts service by a bailiff next to the registered letter.
Is my notice on a Dutch lease invalid if it was not registered?
Not automatically. A court of appeal has held that missing that form does not void the notice if the letter was received. You then have to prove receipt, which is hard if the landlord confirms nothing. That is what the registered letter is for.
Does a Dutch notice of default have to be registered?
The law asks for a written demand with a reasonable deadline, not a registered letter. Only after that can you usually claim damages or end the contract, so you must be able to prove the letter arrived. For the fourteen-day letter to a consumer, courts refuse collection costs when receipt is not proven.
Can I cancel Dutch insurance or a subscription by email?
Yes. You may always cancel insurance electronically, and a phone, internet or gym subscription by email or web form; if you signed up online, you can cancel online. A term that only allows cancellation by registered mail is presumed unfair. Do ask for a confirmation.
Do I have to resign by registered letter in the Netherlands?
No. The law sets no form, but the government advises resigning in writing and asking for an acknowledgement of receipt. Registered mail helps if your employer does not confirm and the notice period is tight.
