Can one roommate terminate the lease alone?

Generally, one roommate cannot effectively end the joint lease alone. Normally, all tenants must terminate together, or the landlord must agree to a contract amendment.

Who remains liable for rent after one roommate moves out?

Moving out does not generally end contractual liability. Until the tenancy is effectively ended or the tenant is released from the lease, all contract partners may remain liable for the full rent and other contractual obligations.

Can a replacement tenant automatically replace a roommate?

No. A replacement tenant does not automatically replace an existing contract partner. An agreement with the landlord and the affected tenants is normally required.

Which court handles a tenancy dispute?

The Amtsgericht is generally responsible for typical disputes arising from a residential tenancy. Subject to statutory requirements, an appeal may be brought before the Landgericht.

Termination by Tenant 4 min read · published April 04, 2026

Tenants in Germany who have signed a lease together with others cannot usually leave the agreement alone. This applies to shared apartments, couples, and families. For renters, it is especially important to know whether all contract partners must give notice, who remains liable for rent and damage until the tenancy ends, and whether a replacement tenant is sufficient. A clear agreement with the roommates and landlord can prevent disputes. This overview explains the key rules on tenant termination, joint liability, and practical steps for ending the tenancy safely.

What joint liability means

If several tenants sign the same lease, they are commonly treated as jointly responsible for the contractual obligations. In practice, the landlord may generally demand the full rent from any one of the tenants, rather than only that person's share. Internal arrangements between roommates do not automatically change the landlord's rights.

Moving out alone does not normally release a tenant from a jointly signed lease.

The legal basis includes the German Civil Code (Bürgerliches Gesetzbuch, BGB), particularly the rules on joint obligations and residential tenancies.^[1] A tenant who pays more than their internal share may usually seek reimbursement from the other responsible tenants, depending on the agreement and circumstances.

How termination works for roommates

All tenants usually need to act together

A single tenant generally cannot terminate the entire joint lease alone. The usual route is for all tenants to sign one notice of termination and send it to the landlord. The statutory notice period for ordinary tenant termination is generally three months, although the exact calculation depends on when the notice reaches the landlord and the lease terms.^[2]

Prepare one written notice naming all tenants and the rented property.
Keep a copy of the signed notice and proof that the landlord received it.
Check the applicable deadline before choosing the termination date.

Leaving the lease before it ends

If only one roommate wants to leave, that person should not assume that handing back keys or moving out is enough. The remaining tenants and the departing tenant can ask the landlord to agree to a contract amendment or a replacement tenant. The landlord is not automatically required to accept either option, unless a specific agreement or exceptional legal rule applies.

Do not rely on a verbal promise that you have been released from the lease.

Obtain a written agreement stating the effective date of the release, the handling of the deposit, and any remaining rent or utility payments. Without such an agreement, the departing tenant may remain liable even after moving out.

Rent, damage, and the deposit

Until the tenancy is effectively ended or a tenant is formally released, the landlord may pursue contractual claims against the tenants who signed the lease. This can include unpaid rent, agreed operating costs, and justified claims for damage. The landlord must still meet the legal requirements for each claim; joint liability does not remove the need to prove an amount that is actually owed.

Continue arranging full and timely rent payments until the agreed end date.
Keep payment records, inspection notes, photographs, and messages about the apartment.
Agree in writing how the security deposit will be divided or returned.

Roommates should also settle their internal accounts separately. A written agreement can record who pays outstanding rent, utility adjustments, repairs, or a share of the deposit. Such an agreement does not bind the landlord unless the landlord is also a party to it.

Written notice and evidence

A termination notice should identify the tenants, the address, the intended termination date, and the clear intention to end the lease. All tenants who are required to terminate should sign it. The notice should reach the landlord in a way that can later be proven, such as personal delivery with a witness or another reliable delivery method.

A dated copy and reliable proof of delivery can be decisive if the termination date is disputed.

If the landlord refuses to confirm receipt, keep all correspondence and do not delay in seeking advice. A tenant association, qualified legal adviser, or lawyer can review the lease and the proposed notice. Legal expense insurance may also have notification requirements.

Disputes and responsible courts

Rental disputes such as claims about rent, termination, possession, or damages are generally brought before the local Amtsgericht. In suitable cases, an appeal may proceed to the Landgericht, while the Bundesgerichtshof can decide legal questions in proceedings that reach it. Procedural rules, including rules for eviction actions, are mainly found in the Code of Civil Procedure (Zivilprozessordnung, ZPO).^[3]

If court documents arrive, observe every stated deadline. An eviction lawsuit or payment claim should not be ignored, even if the tenant believes the landlord is wrong. Collect the lease, termination notice, delivery evidence, payment records, and communications before obtaining legal help.
