In a sublease agreement, what remains with the original tenant?

In a sublease agreement, the original tenant retains the estate itself in the form of their leasehold interest. This means that while the tenant can transfer some of their rights to the subtenant, they still remain responsible for the overall lease agreement with the landlord.

The tenant's responsibility typically includes paying rent to the landlord and maintaining the property per the original lease agreement. Therefore, even when a portion of the property rights is passed on to the subtenant, the original tenant must uphold their obligations to the landlord, which is why they maintain the estate itself. This legal framework ensures that the landlord can still enforce the lease terms against the original tenant, providing a layer of security for the landlord despite the sublet arrangement.

The other options—such as merely retaining the right to collect rent or none of the responsibilities—do not accurately capture the original tenant's rights and obligations under a sublease. The essence of a sublease is that while some rights are transferred, the overarching responsibilities and rights concerning the leasehold interest remain with the original tenant.
