## Short definition

A grant of occupancy from the prime tenant to a sub-tenant.

## Full definition

Under a [sublease](/topics/sublease-strategy), the prime tenant remains contractually liable to the landlord. Sublease typically requires landlord consent. Sublease economics in soft markets typically clear at a 25-40% discount to direct space.

## Why this matters for Class A leasing

Sublease is part of the lease structure vocabulary that institutional [Class A](/glossary/class-a) occupiers, landlords, and advisers use across Global markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
