Documents for Tenants: Rent Increase in Denmark

Rent, regulation & indexation 2 min read · published September 11, 2025

As a tenant in Denmark, a rent increase can feel confusing and worrying. This article explains which documents you should gather to have an increase reviewed — from a copy of the lease and past rent statements to photographs of the property condition, correspondence with the landlord and receipts for repairs or improvements. We explain how to organize evidence, the applicable deadlines, and when to contact the rent tribunal or seek legal advice. The aim is to provide clear, practical steps so you as a tenant can assess your chances of having an increase reduced or rejected without legal background.

Which documents should you collect?

Collect documentation early so you have a clear overview when filing a complaint. The following documents are typically most important:

  • Copy of the lease agreement.
  • Overview of rent payments and receipts.
  • Correspondence with the landlord, including emails and letters.
  • Photographs of the property condition and any defects.
  • Receipts for improvements or repairs.
Gather documents in chronological order for easier review.

How do you organize evidence?

Organize both physical and digital copies. Check relevant rules in the Rent Act for deadlines and formal requirements[1] before submitting material.

  • Note dates for notices, payments and correspondence.
  • Take clear photos and save them with dates or filenames.
  • Collect payment receipts and bank statements with dates.
  • Save emails and letters as PDFs to ensure readability.
Respond to letters or demands within the deadline to preserve your rights.

Submitting to the rent tribunal or court

You can usually start by complaining to your local rent tribunal; borger.dk has guidance on submitting complaints and required documentation[2]. If the case is complex or the tribunal cannot resolve it, the matter can go to the courts or require legal advice. Contact the rent tribunal if you are unsure about local procedures[3].
