As a tenant in the Netherlands it is important to know which documents are needed when your landlord applies an indexation or annual rent increase.

We cover examples of evidence, how to organize payment records and when you can involve the Rent Tribunal. This practical explanation helps you understand your rights and be prepared for talks with the landlord or for a complaint. Always try to make copies and keep correspondence for a clear file.

Which documents do you need?

In an indexation or rent increase situation good evidence is often decisive. Collect these documents so you can quickly show what was agreed and what was paid.

  • Tenancy agreement (signed copy).
  • Payment proofs (bank statements or receipts) of rent payments.
  • Correspondence with the landlord (emails, letters and registered mail).
  • Photos and reports of defects or repairs.
Keep original documents and make copies for yourself.

Deadlines and legal rules

Rent indexation and rent increases fall under rules in the Civil Code Book 7, which specify when and how an increase may take place.[1] Pay attention to notice deadlines and that some increases are only allowed under conditions.

  • A rent increase must meet conditions and be announced within legal deadlines.
  • Note receipt dates and monitor response deadlines when objecting.
Respond to official notices within the stated deadline to preserve your rights.

If you disagree

If you disagree with the increase you can file an objection and possibly involve the Rent Tribunal for assessment of rent and service charges[2]. For procedural information and government guidance you can also consult the official sites[3].

  • Create an overview with dates, amounts and copies of all correspondence.
  • Submit a written objection to your landlord and keep proof of sending.
