Deposit & blocked account 3 min read · published September 11, 2025

As a tenant in Norway, losing a key or worrying about what happens to your security deposit can be stressful. This article explains what you as a tenant should do first, which deadlines apply, what costs a landlord may deduct from the deposit, and how to document the incident. You get concrete steps to report the loss, request a deposit refund, and what you can claim if a dispute arises. The language is simple, and we show where to find official guidance and complaint options. The goal is for you to know your rights and act quickly to protect both keys and deposit.

What to do first

Take the following actions as soon as you discover you have lost a key. Notify the landlord in writing and ask for instructions; many deposit questions relate to the Tenancy Act.[1] Note time and place, and take photos of relevant circumstances. If there is a risk of burglary or misuse, contact the police.

  • Notify the landlord in writing with date and time.
  • Document the loss with a short description and any photos.
  • Request written confirmation of any costs related to lock changes or new keys.
  • Consider filing a police report if you suspect theft or misuse.
Keep all written communication with the landlord for later documentation.

What can a landlord deduct from the deposit?

A landlord may normally claim compensation for documented damage beyond normal wear and unpaid rent. The landlord must be able to show receipts or other documentation for amounts deducted from the deposit. If there is disagreement about the validity of a deduction, the case can be brought to the Tenancy Disputes Board or the courts for resolution.[2]

Do not let the landlord charge the deposit without written documentation and an itemized list of costs.

How to document and claim a refund

To get your deposit back, gather all relevant documents: confirmation of the deposit account, payment receipts, photos of the property's condition at move-out, and written communication with the landlord. Send a formal request for refund asking for settlement within a set deadline.

  • Request an explanation of any deductions in writing within a reasonable time.
  • Keep copies of all receipts and photos showing the property's condition.
  • If you cannot agree, file a complaint with the Tenancy Disputes Board or the courts.[3]
