What is a licence to assign in a commercial lease assignment?

A licence to assign is a formal document in which the landlord consents to the tenant assigning the lease to a named assignee. It often sets conditions, such as payment of arrears, legal costs, or an authorised guarantee agreement.

What is an authorised guarantee agreement in a lease assignment?

An authorised guarantee agreement, or AGA, is a guarantee given by the outgoing tenant for the assignee’s lease obligations. It is commonly required by landlords as a condition of consent to assignment.

What does a guarantor do in a commercial lease assignment?

A guarantor may support either the outgoing tenant or incoming tenant. In some assignments, a guarantor guarantees payment of rent and performance of lease obligations if the relevant tenant defaults.

Does the assignor remain liable after assigning a commercial lease?

In most cases, liability passes to the assignee after completion, but the assignor may remain liable under an AGA or older lease rules. The exact position depends on the lease date, lease terms, and assignment documents.

What obligations does the assignee take on after lease assignment?

The assignee usually takes on the tenant obligations for the rest of the lease term, including rent, service charge, insurance contributions, repair obligations, use restrictions, and compliance with lease covenants.

What is the solicitor’s role in a UK commercial lease assignment?

A solicitor commonly drafts or reviews the deed of assignment, licence to assign, title documents, completion arrangements, and registration requirements. Legal advice is important because commercial lease liabilities can be significant.

What role can a managing agent have in a lease assignment?

A managing agent may handle practical landlord functions, such as collecting rent and service charge, providing arrears statements, coordinating consent requests, and supplying building management information.

Who signs a deed of assignment of lease?

The deed of assignment is usually signed by the assignor and assignee, and sometimes by the landlord if consent or covenants are included. Execution requirements depend on whether each party is an individual, company, LLP, or partnership.

What happens on completion of a commercial lease assignment?

Completion occurs when the assignment becomes legally effective. The assignor transfers the lease interest, the assignee becomes tenant, completion monies may be paid, and any required notices or registrations are dealt with afterwards.

What is a notice of assignment in a commercial lease?

Notice of assignment is a formal notification to the landlord that the lease has been assigned. Many leases require the assignee to serve notice and pay a registration fee after completion.

Does the assignee need to register the lease assignment at HM Land Registry?

If the lease is registered, or registration is otherwise required, the assignee may need to register the assignment at HM Land Registry. This protects the assignee’s legal title to the leasehold interest.

When is a superior landlord involved in a lease assignment?

A superior landlord may be involved where the immediate landlord itself holds a leasehold interest. Consent may be needed from both the landlord and superior landlord if the lease or superior lease requires it.

How does a lease assignment affect an undertenant or subtenant?

An undertenant or subtenant may remain in occupation under an underlease after the headlease is assigned. The assignee becomes the new immediate landlord of the undertenant, subject to the underlease terms.

What happens to a rent deposit on assignment of a commercial lease?

A rent deposit holder, often the landlord or stakeholder, may need to release, transfer, or replace a rent deposit. The parties should check whether a new rent deposit deed is required for the assignee.

Why are party roles important in a UK commercial lease assignment?

Parties and roles are essential because each party’s consent, liability, covenants, execution method, and post-completion duties affect whether the deed of assignment is valid and commercially effective.

Who Usually Signs A Deed Of Assignment Of Lease?

In a UK commercial lease assignment, the assignor and assignee commonly sign the deed transferring the outgoing tenant\'s leasehold interest. The landlord may instead give consent by a separate licence to assign, but may also be a party where the structure includes direct covenants, an authorised guarantee agreement, release wording, or simultaneous landlord approvals.

Which Parties Can Delay A Commercial Lease Assignment?

The main timing risks usually sit with the landlord, any superior landlord, any lender with security over the lease or freehold, and any required guarantor. If the lease requires consent, notices, references, bank guarantees, rent deposit deeds or lender consent, completion should not be assumed until those requirements are satisfied.

Why Do Guarantors And AGAs Matter?

For leases granted on or after 1 January 1996, the Landlord and Tenant (Covenants) Act 1995 changed continuing liability rules. However, a landlord may still require the outgoing tenant to give an authorised guarantee agreement for the assignee\'s performance if the lease and statutory conditions allow it. This can leave the assignor with post-completion financial exposure.

What Should Parties Check Before Completion?

Lease restrictions: check alienation clauses, consent conditions, notice requirements and whether a deed or licence is prescribed.
Identity of signatories: companies, LLPs, partnerships, trustees, charities and insolvency office-holders may have different execution and authority requirements.
Third-party consents: confirm landlord, superior landlord, lender, management company and guarantor involvement early.
Completion deliverables: agree apportionments, assignment deed, licence to assign, AGA, rent deposit deed, notices, keys, certificates and any Land Registry forms where registration is required.
