Real Property

Landlord and tenant signed a contract for a lease of one year. Lease states that it does not allow for subleasing or illegal drug use. A few months into the lease, tenant subleases to another tenant. The new tenant knows about the old lease between landlord and original tenant. Landlord has no idea of new tenant. When new tenant takes over, he stopped paying. When landlord finds out about new tenant, landlord wants an eviction and for them to pay for the remaining months.
