A commercial lease assignment can be a key part of selling your business if your business trades from rented premises. You may have found a buyer, agreed the price, and prepared to hand over the business, but the sale may not complete until the lease transfer has been dealt with.
This is where many sellers run into delay. The buyer wants the premises, the landlord wants checks done, and the seller wants to move forward. If the lease assignment is not handled early, it can hold up the whole sale.

What Is a Commercial Lease Assignment?
A commercial lease assignment is the transfer of an existing lease from one tenant to another.
In a business sale, the seller is usually the outgoing tenant. The buyer becomes the incoming tenant. After the assignment completes, the buyer usually takes over the lease obligations from that point onward.
This matters because the buyer may need the same premises to keep the business running. For example, a restaurant, salon, takeaway, shop, office, or warehouse may rely on its location. If the lease cannot be transferred, the sale may become difficult or even fall through.
Why Sellers Must Check the Lease Early
The lease will say if assignment is allowed and what steps must be followed.
Most commercial leases do not let tenants transfer the lease without the landlord’s written consent. This consent is usually recorded in a document called a licence to assign. Practical Law describes a licence to assign as the landlord’s consent for the tenant to assign a lease.
Sellers should not wait until the buyer is ready to complete before checking the lease. If the landlord’s consent is needed, the process can take time. The landlord may ask for information about the buyer, raise questions about the premises, or require other documents before agreeing.
Why Landlord Consent Matters
A landlord will usually want to know that the buyer can meet the lease obligations. This means the landlord may look at the buyer’s finances, business experience, proposed use of the property, and references.
The landlord may also check if the seller has complied with the lease. If there are rent arrears, unauthorised alterations, repair issues, or other breaches, the landlord may ask for these to be resolved before giving consent.
This can cause a problem if the seller has already agreed a completion date with the buyer. The sale may need to wait until the landlord is satisfied.
What Sellers Usually Need Before Completion
A commercial lease assignment usually needs several moving parts to be ready at the same time. The business sale documents, landlord consent, buyer checks, and lease transfer documents all need to line up before completion.
The main documents may include:
- A licence to assign
- A deed of assignment
- The business sale agreement
- An Authorised Guarantee Agreement, if required
- A rent deposit deed, if the landlord asks the buyer for one
- Replies to lease enquiries
- Completion statement and rent apportionments
The exact documents depend on the lease and the landlord’s requirements.
The Licence to Assign
The licence to assign is the landlord’s formal written consent to the lease transfer.
It usually confirms that the landlord agrees to the seller assigning the lease to the buyer. It may also set conditions. For example, the landlord may require the seller to enter into an Authorised Guarantee Agreement or require the buyer to provide a rent deposit or guarantor.
The licence to assign is usually signed by the landlord, the seller, and the buyer. Completion should not take place until this document is agreed and ready, unless your solicitor has advised you on the risk.
The Deed of Assignment
The deed of assignment is the document that transfers the lease from the seller to the buyer.
The licence to assign gives permission. The deed of assignment carries out the transfer.
Once completed, the buyer usually becomes responsible for the tenant obligations under the lease. This includes rent, service charge, repairs, insurance payments, and compliance with the lease terms.
However, the seller may still have some risk if an Authorised Guarantee Agreement is required.
Authorised Guarantee Agreement Risk
An Authorised Guarantee Agreement, often called an AGA, is one of the most important documents for a seller to understand.
An AGA means the outgoing tenant guarantees the incoming tenant’s lease obligations. Practical Law describes it as the outgoing tenant’s guarantee of the incoming tenant’s obligations to pay rent and perform the tenant covenants under the lease.
This can create risk after completion. If the buyer fails to pay rent or breaches the lease, the landlord may be able to claim against the seller.
For a seller, this can feel unfair because the business has already been sold. But if the lease allows the landlord to ask for an AGA, it may be part of the assignment process.
Before signing, the seller should know how long the AGA lasts, what it covers, and when liability ends.
Buyer Information the Landlord May Request
The landlord may ask for details about the buyer before giving consent. This is common because the landlord wants to know who will take over the lease.
The buyer may need to provide financial evidence, references, identity documents, business background, and details of their intended use of the premises. If the buyer is a new company, the landlord may ask for a personal guarantee or rent deposit.
This can delay completion if the buyer is slow to provide information.
As a seller, you cannot always control the buyer’s speed, but you can tell the buyer early what is likely to be needed.
Existing Lease Problems Can Delay Completion
Before completion, the seller should check if there are any issues under the lease.
For example, if the seller has changed the layout, installed signage, added equipment, or carried out works without consent, the landlord may raise this during the assignment process.
The same applies to rent arrears or repair issues. A landlord may refuse to deal with the assignment until those points have been resolved.
This is why sellers should review the lease and the history of the premises before the sale reaches completion stage.
Rent, Service Charge and Other Payments
Rent and service charges need to be dealt with at completion.
If the seller has paid rent in advance, the buyer may need to reimburse the seller for the period after completion. If there are arrears, the landlord may require payment before consent is given.
Service charge can be more complicated. There may be balancing payments, estimated charges, or later adjustments. These should be dealt with in the sale agreement so both sides know who is responsible.
What If the Buyer Wants to Change the Premises?
A buyer may want to change the premises after taking over the business. They may want new signage, a different layout, new equipment, or a different trading use.
This should be checked before completion. If the buyer’s plans do not fit the lease, the landlord may refuse consent or ask for further documents.
For example, a lease may allow use as a retail shop but not as a takeaway. If the buyer plans to change the use, the buyer may need landlord consent, planning advice, or licence approval.
This can affect the timing of the sale.
Common Causes of Delay
Commercial lease assignment delays often happen because sellers start the process too late.
The most common causes include:
- The lease has not been reviewed early
- Landlord consent has not been requested
- The buyer has not supplied financial information
- The landlord asks for an AGA
- There are rent arrears
- There are repair or dilapidation issues
- Alterations were made without consent
- The buyer wants to change the use
- The landlord’s legal costs have not been agreed
Some delays cannot be avoided, but many can be reduced by dealing with the lease before completion is close.
What Sellers Should Do Before Completion
The seller should speak to their solicitor before agreeing a firm completion date. The lease position should be checked alongside the business sale terms.
A practical starting point is to gather the lease, any licences for alterations, rent statements, service charge demands, insurance details, and any correspondence with the landlord about the premises.
If the seller knows there are issues, such as unpaid rent or missing consent for works, these should be raised early. Trying to hide or delay them can cause bigger problems when the landlord or buyer asks questions.
How a Solicitor Can Help
A solicitor can review the lease and explain what is needed for the commercial lease assignment. They can also deal with the landlord’s solicitor, prepare or review the licence to assign, advise on the deed of assignment, and check any AGA before it is signed.
This matters because sellers often want a clear legal process that lets them focus on the business sale, not last-minute lease problems. Onyx Solicitors’ target clients value clear terms, responsive advice, and support that helps avoid costly legal mistakes.
Final Thoughts
A commercial lease assignment should be dealt with early when selling a business. The lease transfer is often as important as the sale agreement because the buyer may need the premises to keep the business running.
Before completion, sellers should check the lease, request landlord consent, deal with any rent or repair issues, and understand the risk of signing an Authorised Guarantee Agreement.
A sale can move more smoothly when the lease documents are ready before the completion date arrives.
