Kernrechtsfrage
Whether the co-signing spouse was a tenant under the lease or merely a surety for her husband
Extrahierter Entscheid
She was a contractual tenant and jointly liable under the lease, not a suretyship.
Extrahierte Begründung
No proven common actual intent to create a mere security arrangement. Interpreted objectively, the lease named her as tenant, she signed as such, and the landlord could in good faith understand her as a party to the lease.
