This practical guide clearly shows how to check deadlines, document form errors and use sample forms so you can robustly assert your tenant rights. The guide is aimed specifically at flatshare members, explains district court jurisdiction, necessary evidence and possible next steps up to filing a claim, without legal jargon. At the end you will find a short how-to, FAQ, official help links and footnotes to the BGB, sample forms and court resources so you can act concretely.

What are form errors and why they matter

A form error occurs when a rent increase is not communicated to the tenant according to the statutory requirements of the BGB or mandatory information is missing. Form errors can render a rent increase invalid or reset deadlines; therefore check date, signature, justification and statutory references carefully.^[1]

5 steps for shared-flat tenants

1. Check deadlines and preserve them immediately (deadline).
2. Document every form error with photos and copies (document).
3. Continue to pay rent on time, mark payments as "without prejudice" if necessary (rent).
4. Send a written statement and request correction/sample form from the landlord (form).
5. If no agreement, clarify jurisdiction and possible court action at the district court (court).

If you are unsure about wording or deadlines, consult local advice or check the federal ministry's sample forms before replying.^[2]

When to involve the court?

Court action makes sense if the landlord enforces the rent increase despite documented form errors. In tenancy law, district courts are usually competent; there you can contest rent increases, reduce rent or respond to eviction claims. Check evidence and deadlines first and seek advice where possible.^[3]
