Why Do I Need To Have My Transfer Of Lease Reviewed? (2026 Updated)

If you're taking over a new premises (or handing your current premises to someone else), a transfer of lease can feel like a straightforward "paperwork step" to get the keys handed over and the business moving.

But in practice, a transfer of lease is one of those documents that can quietly lock you into ongoing costs and liabilities for years - even after you think you're "done" with the premises.

That's why having your transfer of lease reviewed isn't just about being cautious. It's about making sure you understand what you're committing to, what risks you're inheriting, and what you can negotiate before you sign.

Below, we'll break down what a transfer of lease actually is, why a review matters (for both outgoing and incoming tenants), and the key red flags to look out for in 2026.

What Is A Transfer Of Lease (And What Documents Are Usually Involved)?

In commercial property, "transfer of lease" usually refers to an assignment of lease.

That's where the existing tenant (the assignor) transfers their lease to a new tenant (the assignee) and the landlord consents (often with conditions). In other words, the lease continues - but with a different tenant.

It's different from:

• Grant of a new lease (where the landlord and new tenant enter a fresh lease).
• Subletting (where the original tenant stays on the hook and grants a sublease to someone else).
• A licence to occupy (a more flexible arrangement that may not give the same security and rights as a lease) - if you're weighing up alternatives, it helps to understand how an Licence to Occupy works in a commercial setting.

In many transactions, "transfer of lease" is used loosely to describe the whole package of documents involved in an assignment. That package can include:

• Licence to Assign (the landlord's formal consent document, usually with conditions)
• Deed of Assignment (the legal document that actually transfers the lease)
• Authorised Guarantee Agreement (AGA) (where the outgoing tenant guarantees the incoming tenant's performance)
• Rent deposit deed or deposit top-up documents
• Side letters (e.g. regarding repairs, payment arrangements, or completion mechanics)

Because these documents work together, reviewing "just the deed" without checking the lease itself (and the landlord consent conditions) can leave you exposed.

Why Having Your Transfer Of Lease Reviewed Matters (Even If The Lease Is "Standard")

Commercial leases aren't like consumer contracts where you can rely on broad cancellation rights. Once you're in, you're in - and if things go wrong, the numbers can escalate quickly.

A legal review helps you understand what you're really agreeing to, including hidden liability that isn't obvious from a quick skim.

1) You Could Inherit Expensive Repairs And Dilapidations

One of the biggest "surprise bills" in commercial property is repairs.

Depending on the lease, you could be responsible for:

• internal repairs only
• internal plus structural repairs
• a share of building-wide costs (service charge)
• reinstatement obligations (returning the unit to its original condition at the end)

When you take an assignment, you often take the premises as-is - but your repairing obligations may be based on what the lease says, not what is fair. A review helps you check what the lease requires and what you can negotiate as part of the assignment (for example, requiring the outgoing tenant to fix issues before completion, or adjusting the price).

2) You Might Still Be Liable After You "Leave" (Outgoing Tenant Risk)

If you're the outgoing tenant, it's a common misunderstanding that assignment automatically means you walk away.

In many leases, the landlord will require an AGA as a condition of consent. This means you may guarantee the new tenant's obligations. If the assignee defaults, the landlord can come after you.

That risk needs to be properly understood before you sign - including the duration of the guarantee, what triggers liability, and whether you can negotiate limits.

3) The Landlord's Consent Can Add New Obligations

Landlord consent isn't always a simple yes/no. The licence to assign can include additional terms, such as:

• payment of the landlord's legal and surveyor costs
• conditions about rent deposits (new deposit, top-up deposit, or replacement deposit)
• requirements for guarantors
• undertakings about reinstatement works
• completion deadlines (with consequences if you miss them)

If you don't review the consent documents properly, you might sign up to conditions that were never in the lease originally.

4) The Transaction Structure Affects Your Negotiating Power

A review also helps you understand where you have leverage.

For example:

• If you're the incoming tenant and the outgoing tenant needs to exit quickly, you may be able to negotiate repairs, a contribution to costs, or updated inventory and handover terms.
• If you're the outgoing tenant, you may want a clean break, but you might have to balance that against what the landlord will accept.

Without a clear view of the legal position, it's easy to negotiate the wrong thing (or assume you can negotiate something that the lease doesn't allow).

The Key Legal Risks Hidden In Transfers Of Lease (2026 Red Flags)

A transfer of lease review isn't just checking spelling and dates. It's about identifying clauses that change your risk profile.

Here are common red flags we see in assignments and related documents.

Authorised Guarantee Agreements (AGA) That Go Further Than You Expect

If you're the outgoing tenant, an AGA can be a deal-breaker or a manageable risk - depending on the wording.

A review helps you check:

• Whether the AGA is required under the lease (or just being requested as a default)
• Whether your guarantee ends on a further assignment, or could effectively continue for longer
• Whether you're guaranteeing all obligations (rent, service charge, repairs, reinstatement) without any cap

Rent Deposit Issues And "Top-Up" Traps

Rent deposits often come up during assignment, especially if the landlord is nervous about the incoming tenant's financial position.

It's important to check:

• Who is paying the deposit (incoming tenant, outgoing tenant contribution, or split)
• Whether the deposit is being assigned/transferred or replaced with a new deposit
• The conditions for return and what the landlord can deduct

Even experienced business owners get caught out here. If you're dealing with deposits, it's worth being familiar with the common issues around Commercial Lease Deposits.

Service Charge, Insurance Rent, And Hidden Building Costs

Rent is rarely the only cost.

Your lease may include:

• service charge (contributions to building maintenance and management)
• insurance rent (reimbursement of landlord's insurance premiums)
• management fees
• sinking funds or reserve funds

A review should identify:

• what you actually have to pay
• how it's calculated
• whether there are caps, exclusions, or audit rights

Restrictions On Use, Alterations, And Signage

It's common for incoming tenants to assume they can "fit out" the premises to match their brand or operations. But the lease may restrict:

• your permitted use (including narrow use clauses)
• hours of trade
• signage and external branding
• internal alterations without landlord consent
• installation of extraction, ventilation, or specialist equipment

If you're taking over a premises for a new concept (say, changing a retail shop into a food venue), these restrictions can make the premises commercially unusable for you - even though the rent looks great.

Break Clauses That Don't Actually Let You Break

Break clauses are often misunderstood. A "tenant break option" might be conditional on things like:

• no rent arrears
• no other breaches (even minor ones)
• vacant possession
• strict notice requirements

If you're relying on a break clause as your "exit plan", you'll want to confirm the conditions are realistic and that you can comply with them.

Execution Problems: If It's Not Signed Properly, You Can Create A Mess

Assignments and landlord consents are often signed as deeds. If execution formalities aren't followed, you can end up with an unenforceable document - or a dispute about whether the transfer is valid.

That's why it helps to understand Executing Contracts And Deeds and, importantly, who can act as a witness. Practical guidance on Witnessing Deeds can save you from last-minute completion delays.

What A Lease Transfer Review Typically Covers (And What You Should Prepare)

A good review is both legal and practical. It should cover what's in the paperwork, but also what it means for your business day-to-day.

Typically, a transfer of lease review includes:

• Reviewing the existing lease to confirm what obligations are being assigned.
• Reviewing the licence to assign to check any new conditions imposed by the landlord.
• Reviewing the deed of assignment to ensure it properly transfers rights and obligations (and doesn't sneak in extra liability).
• Checking for any guarantee/AGA requirements and explaining how they work in practice.
• Confirming completion mechanics (handover date/time, apportionments, keys, service media, alarm codes, etc.).
• Identifying negotiation points before you're locked into signing.

Documents And Information That Help Speed Things Up

If you're getting a review done, you can usually save time (and back-and-forth) if you have:

• a copy of the signed lease and any variations or side letters
• the landlord's draft licence to assign and deed of assignment
• details of the proposed assignee (company number, registered address, trading history)
• any heads of terms agreed between outgoing and incoming tenant (including price and what's included)
• details of any rent deposit and how it's being handled

If you're unsure whether you even have a "proper lease" document (or you're operating on something informal), it's worth understanding the risks around Commercial Tenants Without A Lease before you proceed with any transfer-related decision.

Common Scenarios Where Skipping A Review Comes Back To Bite You

To make this real, here are a few scenarios we regularly see (and why a review matters).

"We Took Over A Shop And Then Got Hit With A Repair Bill"

You take over a lease because the location is perfect and the outgoing tenant seems reasonable. A few months later, you discover:

• the aircon is failing,
• there's water ingress,
• the shopfront needs work,
• the landlord points to the repairing covenant and says it's your responsibility.

A review won't magically remove all repair obligations - but it can flag the risk early so you can negotiate a price adjustment, require works before completion, or consider whether a different premises makes more sense.

"I Assigned The Lease And Thought I Was Finished" Until The New Tenant Stopped Paying?

This is the classic outgoing tenant problem: the landlord required an AGA, the incoming tenant struggled, and now you're being chased.

With the right advice early, you might negotiate:

• an alternative security arrangement,
• a stronger assignee,
• clearer limits or triggers,
• or at least a proper understanding of the worst-case exposure.

"The Deposit Wasn't Returned And Nobody Agrees Who's Entitled To It"

Deposit arrangements can become a three-way argument: landlord vs outgoing tenant vs incoming tenant. If the documents don't clearly deal with assignment/replacement and repayment mechanics, you can end up stuck.

And if you've ever had a landlord delay or refuse repayment, you'll know how painful it can get - the same practical lessons often show up in disputes about Commercial Landlord Deposit Returns.

Key Takeaways

• A transfer of lease (usually an assignment) can come with multiple documents, and you need to review the full package - not just one deed in isolation.
• If you're the incoming tenant, a review helps you identify hidden liabilities like repairs, service charges, restrictive use clauses, and deposit risks before you're locked in.
• If you're the outgoing tenant, a review is crucial because you may still be liable after assignment through an AGA or other guarantee-style obligations.
• Landlord consent documents can impose new conditions (costs, guarantors, deposits, deadlines), so they need careful checking.
• Assignments are often executed as deeds, and signing/witnessing errors can delay completion or create disputes about validity.
• Even if the lease looks "standard", the commercial impact of a few clauses can be huge - getting advice early is usually cheaper than dealing with a dispute later.
