Rent during break-ups

If a breakup occurs while renting together, you are in principle obligated to pay rent as long as the tenancy continues. When joint liability has been agreed, the landlord may in principle direct claims against both tenants, even if one of them has moved out.
As a general rule, each tenant has the right to terminate the tenancy with the landlord. It is therefore important to give notice of termination for your own part if you move out after a breakup and do not wish to remain responsible for the other tenant.
If neither party has the financial means to keep the apartment alone, the tenancy must either be terminated or subletting considered. When one tenant gives notice and moves out, this may provide grounds for termination by the landlord if it results in the remaining tenant being unable to pay the rent.
Other disputes than can occur
The contract cannot be terminated through ordinary termination
The tenant moves out before the end of the tenancy or notice period
