What is a rent overpayment?

A rent overpayment occurs when a tenant has paid more than is stipulated by the lease or law. The legal basis and detailed rules regarding landlord obligations and tenant rights can be found in the Act on the Protection of Tenants and civil law provisions.[1]

Keep all rent receipts and proof of payments.

Documents to collect

  • Bank transfer confirmations (rent) and proof of payments.
  • Lease agreement and annexes (document).
  • Receipts or invoices for utility charges (payment).
  • Sample refund demand or letter to the landlord (form).
Respond to formal letters within deadlines to avoid losing rights.

What to write in the refund demand

The refund demand should include: party details, exact overpaid amounts, the period concerned, a request for refund with the bank account number and a deadline for reply (e.g. 14 days). Attach copies of payment proofs. Refer to your tenant rights as the legal basis for the demand.

Sample paragraph for the letter

Please refund the overpaid amount of X PLN for the period from [date] to [date]. Attached are copies of payment confirmations. Please transfer the funds to account: [account number] within 14 days of receipt of this letter.

Frequently Asked Questions

How long do I have to report an overpayment?
Claims for refund are subject to limitation periods under the Civil Code; deadlines vary by situation, so act promptly and check the specific legal deadline.[2]
Can I offset the overpayment against future rent?
Offsetting may be possible in some cases, but unilateral offsets without agreement can cause disputes; it is better to send a refund demand and obtain the landlord's consent.
Does the landlord have to refund with interest?
If the overpayment results from an error or unjust enrichment, the tenant usually has the right to claim a refund with statutory interest from the date of payment.

How to do it

  1. Collect all proof of payments and the lease agreement (evidence).
  2. Prepare and send a refund demand to the landlord by registered mail or email with delivery confirmation (form).
  3. Wait the set period (e.g. 14 days) for a reply or complaint (deadline).
  4. If the landlord does not refund, file a claim at the district court with evidence and a payment demand (court).
  5. After a court win you can enforce the judgment via bailiff; be mindful of costs and possible interest (payment).
Detailed documentation and clear deadlines increase your chance of a quick refund.

Key takeaways

  • Collect proof from the first payment.
  • Send a formal refund demand with a set deadline.
