What we can do for you with assignment and subletting
We act for commercial tenants assigning leases or subletting premises, making sure the deal is structured properly and exposure is controlled.
- Reviewing lease restrictions on assignment and subletting

Assignment and subletting are technical transactions. Landlords often use consent provisions to extract guarantees, add conditions, or slow the process down.
We focus on getting the structure right, controlling the consent process, and limiting the liability you carry forward.
How we approach assignment and subletting
These transactions are controlled by the lease and landlord consent. The priority is to structure the deal properly, manage consent, and control ongoing liability.
Understanding your position
We review the lease, identify restrictions, and confirm what is permitted and on what terms.
Managing consent
We handle the consent process, deal with landlord conditions, and ensure the transaction is not delayed or blocked.
Taking the right next step
We structure the assignment or sublease, limit your exposure, and ensure the deal completes properly.
Key issues in assignment and subletting
These transactions are controlled by lease terms and landlord consent. The risk is not just getting approval, but accepting conditions or liabilities that follow you after the deal.
Lease restrictions
Leases often impose strict conditions on assignment or subletting. Missing these can invalidate the transaction or trigger breach.
Landlord consent
Consent is usually required and often conditional. Landlords may delay, refuse, or impose terms that need to be challenged.
Ongoing liability
Assignment does not always release you. Guarantees and continuing liability are common and need to be controlled.
Structure of the deal
The way the assignment or sublease is documented matters. Poor structure can expose you to risk or invalidate the arrangement.
Most problems arise from landlord control and technical lease conditions, not the deal itself.
The position needs to be managed carefully to avoid carrying risk long after you have moved on.
Assignment & Subletting FAQs
Common questions from commercial tenants dealing with lease transfers, subletting, and landlord consent.
Do I need my landlord’s consent to assign or sublet?
In most cases, yes. Commercial leases usually require landlord consent, and acting without it can put you in breach.
Can a landlord refuse consent?
They can, but not always freely. Many leases say consent must not be unreasonably withheld, but landlords often impose conditions instead.
Am I released from the lease if I assign it?
Not necessarily. Landlords commonly require guarantees, meaning you may still be liable if the new tenant defaults.
What is the difference between assignment and subletting?
Assignment transfers the lease to a new tenant. Subletting keeps you in place while granting occupation to someone else.
What happens if consent is delayed?
Delay is common and can derail transactions. It often needs to be challenged to keep the deal moving.
