As a subtenant, because you didn't sign the original Lease Agreement, in most instances you'll have to contact the original lease holder with any issues you may have about rent or repairs. Unless you have made other arrangements, you will pay your rent to the leaseholder and they will then pay the rent to the landlord. However, in some cases, you can make an agreement with the property manager to be treated as if you were the prime lease holder, and pay rent directly to the landlord or property manager. If you have questions or concerns related to your subletting arrangement, ask a lawyer.
