Tenant Associations & Advice Services 2 min read · published September 07, 2025
Conflicts in shared flats are common for tenants: noise, cost sharing, cleanliness or visiting rules can escalate quickly. Mediation in Germany offers a structured, confidential way to resolve flat-sharing disputes without court proceedings. A neutral mediator helps clarify interests, create shared rules and reach binding agreements. This practical guide explains how mediation works, how tenants should prepare, the role of written agreements and when legal steps at the local court may be necessary. At the end you will find sample wording, guidance on official forms and concrete steps to start mediation.

What is mediation for shared flats?

Mediation is a voluntary process where a neutral person assists hosts and flatmates in finding solutions for recurring conflicts. Unlike court, the focus is on mutual agreement; the mediator facilitates without issuing legal judgments.

Mediation is voluntary and confidential.

When is mediation appropriate?

  • Disputes over cost sharing or rent payments (rent) can often be resolved out of court.
  • Issues with repairs, heating or water (repair) are often solved faster with neutral moderation.
  • Clarifying house rules or visiting policies (notice) is suitable for shared flats.
  • If both sides are willing to present records and communication (evidence), the chance of success increases.
Mediation can be faster and cheaper than proceedings at the local court.

Preparation as a tenant

  • Document incidents with date, time and photos as evidence (evidence).
  • Gather relevant lease contracts, side agreements and messages (form).
  • Name a contact person and clarify who will negotiate (contact).
  • Note your goals and which compromises you would accept (warning).
Well-documented concerns make mediation easier and build trust.

Process and legal framework

A mediation usually starts with an initial meeting. The mediator explains rules and process, then follows joint sessions with confidential exchange. Written agreements at the end can protect rights but are not automatically legally binding; if necessary, agreements must be notarized or enforced in court.

Relevant legal bases are the BGB (tenancy contract, duties) and the ZPO for court procedures.[1][2] In escalating cases the local court (Amtsgericht) is competent; appeals go to the regional court and precedents are published by the BGH.[3]

Respond immediately to time‑bound letters such as notices of termination and seek legal advice.

FAQ

Can mediation prevent a landlord's termination?
Sometimes. If parties find a solution in time, a termination can be withdrawn or a settlement agreement negotiated.
Does a mediation agreement need notarization?
Not necessarily. Written agreements help, but for significant financial matters notarization may be required.
Who pays for mediation?
Typically the involved parties share the costs. Some cities or services offer subsidized or free options.
