What Happens When One Partner Moves Out but Both Are on the Lease?

When both partners are named on a Mietvertrag and one of them wants to move out, the remaining tenant can face real challenges. Both stay responsible for the rent and other obligations unless the lease itself is changed. Understanding your rights and the process can make that transition much less stressful.

What happens if both are on the lease and one partner moves out?

If both partners are on the Mietvertrag and one moves out, both remain liable for rent and other obligations. That means the departing partner is still financially responsible unless the lease is formally amended.

When one partner leaves, the Mietvertrag doesn't change automatically. Both people signed as co-tenants, which makes them jointly responsible for paying the rent. According to ruv.de, the departing partner is still considered a Gesamtschuldner, a joint and several debtor, under the lease. In practice, that means any unpaid rent or Nebenkosten has to be covered by the remaining partner, regardless of who actually moved out.

How can one person be removed from a Mietvertrag?

To remove one person from a Mietvertrag, both tenants have to agree, and the landlord has to approve the change.

The process usually means drafting a new lease or formally amending the existing one to reflect the change of tenant. The landlord may also ask for a new Selbstauskunft, a tenant self-disclosure form, from the remaining tenant to confirm they can cover the Kaltmiete alone. It pays to communicate openly with the landlord early and make sure everyone agrees to the new terms before anything is signed.

Who owns the apartment if both names are on the lease?

Neither partner "owns" the apartment just because both names are on the Mietvertrag. Instead, they have equal rights and obligations as tenants.

A rental agreement never transfers ownership to the tenants. Both partners have an equal right to live in the property for as long as the lease is active. If one partner wants to claim sole tenancy, they need to negotiate that with both the landlord and the other tenant, which can result in a new lease listing only one name.

Can the landlord terminate the lease if one partner moves out?

A landlord cannot simply terminate the Mietvertrag because one partner has moved out. The legal obligation stays with both tenants unless the lease is officially changed.

According to wetterauer-immobilien.de, a landlord has no right to cancel the lease simply because one partner has moved out. The remaining tenant still has to meet every rental obligation, though. If the rent goes unpaid, the landlord could pursue termination for breach of contract.

What if the remaining tenant can't afford the rent alone?

If the remaining tenant can't cover the rent alone, one option is finding a new roommate, or discussing a rent reduction with the landlord.

Subletting the vacated room to someone else, with the landlord's approval, is another way to help cover the Kaltmiete and Nebenkosten. Getting a realistic sense of typical rents in the area also helps when negotiating, which is where Average Rent in Germany per sqm: Regional Variations can help with the numbers.

Conclusion

Navigating a shared Mietvertrag when one partner wants to move out is rarely simple, but understanding your rights and obligations makes it manageable. Both partners stay liable for the rent until the lease is officially changed, so weigh your options and communicate clearly with the landlord as early as possible.
