License to Assign: Meaning and When You Need One in Commercial Contracts

If your business is growing (or changing direction), there’s a good chance you’ll need to transfer a contract at some point. Maybe you’re selling the business, moving premises, bringing in a new operating company, or exiting a project that no longer fits.

That’s where getting a license to assign often comes in.

A license to assign is one of those documents that can feel like “admin” until it becomes the thing holding up a deal. If you’re dealing with a commercial lease, it’s especially common for an assignment to be blocked unless you get the landlord’s written consent in the form of a licence.

Below, we break down what a license to assign is, when you’ll need one, what it typically includes, and the practical steps you can take to keep your transaction moving (without accidentally breaching your contract along the way).

What Is A License To Assign?

A license to assign is a written document where one party gives formal consent for a contract to be transferred (assigned) from one party to another.

In plain English:

• Assignment is the legal process of transferring contractual rights (and sometimes the benefit of the contract) to a new party.
• A license to assign is the permission document that allows that assignment to happen where the original contract says you need consent.

You’ll most commonly see a license to assign in the context of:

• Commercial leases (for example, assigning your lease to a buyer when you sell your business)
• Service or supply contracts (where the contract restricts assignment without the other party’s approval)
• Franchise and distribution arrangements (where control over who operates the business is critical)

It’s worth being clear about one key point: in many commercial agreements, assignment is restricted unless the contract allows it (or the other party consents). That means you can’t just “hand over” the contract because it makes commercial sense. You need to follow the contract wording.

License To Assign Vs Deed Of Assignment Vs Novation (What’s The Difference?)

These terms get mixed up a lot, and the difference matters.

• License to assign: a consent document (permission) that allows an assignment to take place under an existing restriction.
• Deed of assignment: the document that actually effects the transfer (i.e. moves the rights from the old party to the new one). For a deeper look at what assignment involves, a Deed of Assignment is often the starting point.
• Novation: replaces a party to the contract entirely (usually transferring both rights and obligations, and typically requiring all parties’ agreement). If the deal structure requires novation rather than assignment, you may need a Deed of Novation.

As a quick rule of thumb:

• If you only need to transfer benefit/rights, assignment might work (if permitted).
• If you need to transfer responsibilities/obligations too, novation is often the cleaner legal solution.

The catch is that leases and commercial agreements often have their own very specific rules on what’s allowed, and what paperwork is required. This is why getting the documents right upfront can save a lot of back-and-forth later.

When Do Businesses Need A License To Assign?

You typically need a license to assign when your contract includes an “assignment clause” that says something like:

• you must not assign the contract, or
• you may assign only with written consent of the other party (sometimes “not to be unreasonably withheld”).

Here are the most common real-world situations where small businesses run into the “license to assign” question.

1. You’re Selling Your Business And The Buyer Wants The Lease

This is probably the most common scenario.

Let’s say you run a café, studio, warehouse business, clinic, or retail store. Your premises are a big part of the value. When you sell, the buyer often wants to “step into” the existing lease rather than negotiate a whole new lease from scratch.

If your commercial lease says you need landlord consent to assign, you’ll usually need a license to assign signed by the landlord (and often also by you and the incoming tenant).

Because leases can be quite technical (and the consequences of getting it wrong can be expensive), it’s common to get a Commercial Lease Review early, so you know exactly what the landlord can ask for and what the timeline might look like.

2. You’re Restructuring Your Business (New Company, New Group Structure)

It’s normal for growing businesses to change structure over time.

For example, you might move contracts from:

• you personally (as a sole trader) to a limited company, or
• one group company to another (for tax, investment, or operational reasons).

Even if the “people behind the business” are the same, the legal entity on the contract is different. If the contract restricts assignment, you may need consent (and therefore a license to assign) before you can move it.

3. You’re Exiting A Project Or Replacing A Contracting Party

Sometimes you’re in the middle of a longer-term agreement and circumstances change. Maybe you’re a subcontractor who needs another provider to take over, or you’re selling a specific product line and want the customer contracts to follow.

If the contract requires consent to assignment, a license to assign may be necessary to make the transfer valid.

4. Your Lease Or Contract Says Consent “Must Not Be Unreasonably Withheld”

In commercial leasing, there’s a well-known legal framework around consent to assignment.

In broad terms, where a lease requires landlord consent to assignment, landlords must generally deal with requests within a reasonable time and cannot unreasonably refuse consent (and must give reasons if refusing). In England and Wales, this is closely linked to the Landlord and Tenant Act 1988.

However, “not unreasonably withheld” doesn’t mean “automatic yes”. It usually means the landlord can ask for sensible conditions (like references, guarantees, or payment of costs), provided those conditions are consistent with the lease and the law.

What Does A Typical License To Assign Include?

A license to assign isn’t just a one-line “yes, you can assign.” In practice, it often sets out the rules of the handover and protects the landlord (or the party giving consent) from extra risk.

What’s included depends on the contract and the negotiating leverage, but these are common clauses you’ll see.

The Parties And The Contract Being Assigned

The license will clearly identify:

• the outgoing party (assignor)
• the incoming party (assignee)
• the landlord/consenting party
• the lease or contract being assigned (with dates and details)

This sounds basic, but errors here can create real enforceability issues later.

Conditions Of Consent

Consent is often conditional on things like:

• financial and identity checks on the incoming party (references, accounts, bank references)
• authorised guarantee agreement (AGA) requirements (common in leases), where the outgoing tenant guarantees the incoming tenant’s performance
• rent deposit requirements (especially if the incoming tenant is a new or smaller business)
• payment of the landlord’s costs (legal fees and administrative fees)

If you’re the outgoing tenant, it’s important to understand which conditions are standard, which are negotiable, and which might be unreasonable in your specific situation.

Release (Or No Release) Of The Outgoing Party

This is a big one. Many business owners assume that once they assign a lease, they’re “off the hook.” That’s not always true.

Depending on the lease terms and the structure of the assignment:

• you might remain liable via an AGA or guarantee, or
• you may have ongoing liability for historic breaches (e.g. unpaid rent or property damage before assignment).

This is why assignment paperwork should be reviewed carefully, especially where you’re selling a business and want a clean exit.

Execution Formalities

Licences to assign are often executed as deeds, particularly where the underlying lease (or the landlord’s requirements) calls for it. That means signing requirements can be stricter than a standard contract.

If you’re unsure whether something needs to be executed as a deed (and how to do it properly), the rules around executing deeds can matter more than people expect. A document signed incorrectly can cause delays, or worse, create arguments about whether the consent was valid.

How To Request And Negotiate A License To Assign (Without Stalling Your Deal)

When you need a license to assign, time can become a real pressure point - particularly if you’re selling a business with a completion date, or coordinating a move between premises.

Here’s a practical approach that usually keeps things moving.

1. Check The Assignment Clause Early

Before you agree timelines with a buyer or incoming tenant, check:

• Do you need consent to assign at all?
• Is consent “absolute” (landlord can refuse), or “not to be unreasonably withheld”?
• Are there pre-conditions (e.g. no rent arrears, no breach of covenant)?
• Are there notice requirements or specific forms you must use?

If you’re unsure how to interpret the clause, getting a Contract Review early is usually cheaper than trying to fix things after the other side has already raised objections.

2. Prepare A Strong “Consent Pack”

If you’re asking for consent, aim to make it easy to say yes.

A consent pack might include:

• background on the incoming assignee (who they are and what they do)
• proof of funds or accounts
• trade references or professional references
• confirmation they understand and will comply with key lease obligations

Landlords and counterparties often delay because they don’t have enough information to assess risk.

3. Budget For Fees And Timing

In commercial leases, it’s common for the outgoing tenant (or the incoming tenant) to pay the landlord’s legal costs for the licence to assign. That can be frustrating, but it’s a standard feature of many leases.

Build this into your transaction budget, and don’t be afraid to ask for an estimate upfront.

4. Negotiate The Conditions That Really Matter

Some conditions are worth a closer look, such as:

• how long any guarantee lasts
• what triggers liability for the outgoing tenant
• whether the landlord can require an AGA in the circumstances
• whether a rent deposit is proportionate to the risk

Where possible, negotiate in a way that matches the commercial reality. For example, if the incoming tenant is well-established and financially strong, a large rent deposit might not be necessary.

5. Make Sure Your Other Deal Documents Match

If your assignment is part of a broader transaction (like a business sale), make sure the legal documents line up. Your sale agreement may need to deal with:

• what happens if landlord consent is delayed or refused
• who pays which costs
• what information each party must provide
• the target completion date and any extension mechanisms

This is also where good Contract Drafting can save a lot of pain - because assignment issues are predictable, and the contract can plan for them.

Key Risks And Practical Tips For Small Businesses

A license to assign is usually manageable - but there are a few common traps that catch business owners out.

Risk 1: Assigning Without Consent (And Accidentally Breaching Your Contract)

If you assign a lease or contract without the required consent, you may be in breach. In a lease context, that can potentially lead to enforcement action, costs claims, or even steps towards forfeiture (depending on the lease and circumstances).

Practically, it can also spook buyers and investors, because it creates uncertainty around whether the transfer is legally valid.

Risk 2: Assuming Assignment Transfers All Obligations

Assignment typically transfers rights, but obligations are trickier. That’s why many transactions use novation instead.

If you’re not sure whether you need assignment, novation, or both, it’s worth reading the contract carefully and getting advice. The goal is to ensure the new party has the right legal responsibility moving forward, and you’re not left with unexpected liabilities.

Risk 3: Getting Stuck With Ongoing Liability

In leases, outgoing tenants can sometimes remain on the hook through guarantees or AGAs.

Before you sign a license to assign, be clear on:

• what you’re guaranteeing (if anything)
• how long the guarantee lasts
• what events trigger liability
• whether you can require the assignee to indemnify you in the wider deal documents

Risk 4: Delays That Blow Up Your Completion Date

Consent processes can take time - especially if the landlord has slow internal processes or wants extensive information.

To reduce delays:

• start the consent process early
• provide a complete consent pack upfront
• agree who is responsible for chasing and providing information
• avoid signing completion dates that assume consent will be instant

Key Takeaways

• A license to assign is written permission to transfer a contract where the underlying agreement restricts assignment without consent.
• Small businesses most commonly need a license to assign when assigning a commercial lease as part of a business sale, restructure, or premises move.
• A license to assign is different from the document that actually transfers rights (often a deed of assignment), and different again from novation, which replaces a party to the contract.
• Licences to assign often come with conditions like references, guarantees (including AGAs in leases), rent deposits, and payment of the other party’s legal costs.
• Assigning without the required consent can create serious legal and commercial risk - it’s worth checking the assignment clause early and keeping your transaction documents aligned.
• Because the right approach depends on the specific contract wording and deal structure, getting tailored legal help early can save time, cost, and stress.
