Assignment of Lease

A transaction where an existing tenant transfers their entire lease interest and obligations to a new tenant — potentially releasing the original tenant from further liability, unlike a sublease.

Home Glossary Lease Types and Structures Assignment of Lease
Definition

An assignment of lease is a transaction in which an existing tenant transfers their entire interest and obligations under a lease to a new tenant (the assignee), as opposed to a sublease, which retains the original tenant's ongoing liability. Depending on the landlord's consent terms, an assignment can fully release the original tenant from further lease obligations once the assignee takes over.

What to watch for before committing

Release language specificity

Confirm whether the assignment agreement explicitly releases you from further liability, or whether you remain secondarily responsible.

Landlord consent requirements

Understand the landlord's consent process and any conditions they can impose on approving an assignment.

Assignee creditworthiness

If assigning your lease, understand that a financially weak assignee may make the landlord reluctant to grant a full release.

Recapture rights

Check whether the lease gives the landlord the right to recapture the space instead of approving your proposed assignment.

Use restrictions transfer

Confirm whether the assignee's intended use complies with both the original lease's permitted use clause and any zoning requirements.

Documentation and legal review

Given the significance of transferring lease obligations, ensure proper legal documentation and review before finalizing an assignment.

When you need to know this

  • Exiting a lease completely — transferring full lease responsibility to a new tenant rather than remaining liable through a sublease
  • Business sale or acquisition — transferring lease obligations as part of a broader business transaction
  • Relocating before lease expiration — fully exiting a lease obligation rather than managing an ongoing sublease relationship
  • Evaluating exit strategy options — comparing assignment against subleasing or early termination as ways to exit a lease

Frequently asked questions

What is a lease assignment? +
A lease assignment is a transaction in which an existing tenant transfers their entire interest and obligations under a lease to a new tenant, potentially releasing the original tenant from further liability.
What is the difference between assignment and sublease? +
In an assignment, the original tenant may be fully released from lease obligations if the landlord consents to the transfer. In a sublease, the original tenant remains fully liable to the landlord under the primary lease even after subleasing to a third party.
Does assignment always release the original tenant from liability? +
Not necessarily — this depends on the specific assignment agreement and landlord consent terms. Some assignments include a full release, while others leave the original tenant secondarily liable if the assignee defaults.
Can a landlord refuse to consent to an assignment? +
Most commercial leases require landlord consent to assign, and many specify the landlord cannot unreasonably withhold consent, though what counts as "reasonable" grounds for refusal varies by lease language and jurisdiction.
