Outcome

After moving out of a rental flat in Denmark after one year, Andreas Strandfelt was billed a surprisingly high amount for repainting, despite detailed move-in documentation, a thorough move-out inspection and evidence that an identical neighbouring flat had been painted more for less that month. The landlord wouldn't explain the costs. Strandfelt used ChatGPT to structure a complaint to the local rent tribunal, referencing the email thread, the move-in and move-out reports and the relevant legal paragraphs. The tribunal ruled in their favour, and the landlord had to return more of the deposit. The costs were 300 DKK to file and less than 200 DKK for a month of ChatGPT Plus.

ChatGPT

The source didn't share its exact prompt, so we wrote this from what it describes.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Turn my evidence into a clear, well-organised complaint about my landlord's move-out charges for the official tenancy body.

Fill in before running:
- The charges I'm disputing and the amounts: [DETAILS]
- My evidence (emails, move-in and move-out reports, photos): [PASTE / ATTACH]
- Country and the body I'm complaining to: [DETAILS]

You're not my lawyer. Stick to facts I give you, label any rule you mention as something to check against the official source, and keep the tone firm but polite.

Rules:
- Set out a short timeline, then each disputed charge with the evidence that answers it.
- Refer to the rules I give you and mark any rule you add as one I must check against the official source.
- Keep the tone factual and calm.
- Finish with exactly what I'm asking the body to decide.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A structured complaint with numbered references to each piece of evidence.

You'll know it worked when: the tribunal rules in my favour and the deposit is returned.
