Assigning A Lease - How A Deed Of Assignment Works (2026 Updated)

If you’re selling your business, moving premises, or restructuring how you operate, your lease can quickly become the “make or break” detail in the deal.

In many commercial tenancies, you can’t just hand the keys to someone else and walk away. You’ll usually need to assign the lease properly, and that often means preparing and signing a Deed of Assignment (plus getting the landlord’s consent).

This guide is updated for current practice and expectations (including the more formal consent and disclosure processes we commonly see now), but it’s written to stay evergreen so you can use it as a practical checklist whenever you need it.

What Does “Assigning A Lease” Mean?

Assigning a lease is when the current tenant (you) transfers your rights and obligations under the lease to another party (the incoming tenant/assignee). After the assignment takes effect, the incoming tenant becomes the tenant under the lease.

This is different from “just letting someone take over” informally. An assignment is a legal transfer that usually needs:

• Landlord consent (often required under the lease terms); and
• A formal legal document, typically a deed, which records the transfer and the parties’ promises.

In practice, lease assignment usually comes up when:

• you’re selling your business and the buyer wants to operate from the same premises;
• you’re exiting a location but the lease still has time to run;
• you’re reorganising your business structure (for example, moving the lease from you personally to a company, or between related entities); or
• you’re taking over an existing business premises and need the lease moved into your name.

It can feel a bit paperwork-heavy, but getting the assignment right is one of the best ways to protect yourself from lingering liability after you’ve moved on.

If you want a broader overview of the concept before diving into the deed, Assigning a Lease is a helpful starting point.

Why Is A Deed Usually Used?

A deed is commonly used for lease assignments because it’s a formal document that can be enforceable even without “consideration” in the contract-law sense (that’s one reason deeds are popular for transfers). In plain terms: it helps make the assignment legally robust and less open to technical arguments later.

That said, the right document (and process) depends on your lease terms and your situation, so it’s worth getting advice before you sign anything.

When Should You Assign Instead Of Sublease Or Surrender?

When you want to exit a lease, assignment is only one option. The right pathway depends on what your lease allows, what the landlord will agree to, and what outcome you want.

Assignment (Transfer)

Assignment is usually the cleanest “handover” option where the new party steps into the lease as tenant.

This is often preferred when:

• you’re selling a business and the buyer needs continuity of the premises; or
• you want a clearer break from day-to-day lease obligations once the assignment completes (noting some leases can still keep you on the hook in certain ways, which we’ll cover below).

Sublease (You Stay The Tenant)

A sublease is where you remain the tenant under the head lease, and you lease the premises (or part of it) to a subtenant.

This can suit situations where you:

• want to keep long-term control of the site;
• only want to lease out part of the premises; or
• are testing whether you’ll return to the premises.

The key risk is that you usually remain responsible to the landlord under the original lease. If the subtenant doesn’t pay rent or breaches the rules, the landlord typically comes to you.

Surrender (Ending The Lease Early)

A lease surrender is an agreement with the landlord to end the lease early. This can be a great solution where assignment isn’t viable (for example, you can’t find an assignee the landlord will accept).

But surrender is usually a negotiation: the landlord may ask for a surrender payment, conditions, reinstatement works, or other concessions.

If you’re exploring that option, a Lease Surrender Agreement can formalise the end of the relationship and clarify what each party must do (and by when).

So Which Option Is “Best”?

There isn’t a one-size-fits-all answer. The right choice depends on:

• what your Commercial Lease Agreement actually says (especially about consent, guarantees, permitted use, and outgoing obligations);
• how strong your replacement tenant is (from a landlord’s perspective); and
• your appetite for ongoing liability after you leave.

If you’re unsure, it’s smart to get the lease reviewed early-ideally before you commit to a sale timeline or tell a buyer that “the lease transfer will be easy”.

How A Deed Of Assignment Works (Step-By-Step)

Most lease assignments follow a similar path. Your lease may add extra steps (or impose strict timeframes), but here’s the process we commonly see in New Zealand commercial leasing.

1) Check The Lease For Assignment Rules

Start with the lease. Many commercial leases:

• require the landlord’s written consent before any assignment;
• set out what information you must provide about the incoming tenant;
• allow the landlord to impose “reasonable conditions” on consent (for example, requiring a deed of assignment, guarantees, or updated insurance information); and
• require you to pay the landlord’s legal fees (sometimes on a solicitor-client basis).

This is where a lot of surprises live-like a requirement to refurbish the premises before assignment, or a clause that keeps you liable even after you leave.

2) Get The Landlord’s Consent (Usually In Writing)

In most cases, you can’t finalise the assignment until the landlord consents. Practically, the landlord will want comfort that the incoming tenant can meet the lease obligations.

Expect the landlord to ask for things like:

• company and director details (if the incoming tenant is a company);
• financial information or references;
• the intended business activity (to confirm it matches “permitted use”);
• details of any guarantors; and
• proof of insurance and compliance steps (where relevant).

Consent can be straightforward, but delays happen-especially if the landlord’s lawyer is involved, or if there are changes requested as part of the handover.

3) Negotiate Any Related Changes (If Needed)

Sometimes assignment is bundled with changes like:

• updating the “permitted use” (if the new tenant will run a different type of business);
• resetting the rent or rent review dates;
• changing outgoings or maintenance responsibilities; or
• updating the guarantor arrangements.

If the parties are varying the lease at the same time, this might be documented via a Deed of Variation alongside the deed of assignment (or incorporated into the assignment package, depending on drafting and the landlord’s preference).

4) Prepare And Sign The Deed Of Assignment

The deed usually involves three parties:

• Assignor (the outgoing tenant – you);
• Assignee (the incoming tenant); and
• Landlord.

Once signed and dated, the deed will specify an effective date (sometimes called the “assignment date”). From that date, the incoming tenant becomes responsible for performing the lease obligations.

If you need a properly drafted document for this step, a Deed of Assignment of Lease is the standard instrument used to formalise the transfer and record everyone’s responsibilities.

5) Complete The Handover (Practical Completion Steps)

Finally, you’ll usually deal with the practical side of the transition, such as:

• handover of keys, security codes, access cards, and manuals;
• meter readings and transfer of utilities (if applicable);
• condition reports and any agreed reinstatement/repair works; and
• bond transfers or releases (depending on how the landlord holds security).

These details matter. If the handover is messy, disputes can follow-especially about damage, cleaning, signage removal, or make-good obligations.

What Should Be In A Deed Of Assignment (And Landlord Consent)?

Even when landlords have their “standard form”, a deed of assignment isn’t just a formality. The wording can affect who is liable for what, and what happens if something goes wrong after you’ve left.

While each deed is drafted differently, here are the clauses and concepts you should expect to see (and understand) before you sign.

Parties And Background

• Correct legal names of all parties (including NZBN/company number where relevant).
• Clear reference to the original lease (date, premises description, and any variations).
• A statement that the landlord consents to the assignment (often subject to conditions).

Effective Date And Transfer Of Rights

The deed should clearly state:

• the date the assignment takes effect; and
• that the assignee takes over the tenant’s rights and obligations under the lease from that date.

Assignee Covenants (Promises)

The incoming tenant typically promises to:

• comply with the lease terms (rent, outgoings, repair obligations, use restrictions, insurance, etc.);
• pay rent and other sums from the assignment date; and
• perform any tenant obligations that continue over time (like maintenance responsibilities).

Release Of The Assignor (Outgoing Tenant)

This is one of the biggest “watch this carefully” items.

In some assignments, the landlord releases the outgoing tenant from future liability from the assignment date. In other cases, the landlord might only partially release you, or keep you liable in certain scenarios (for example, if the assignee defaults within a certain period).

Whether a release is given (and how broad it is) depends on:

• your lease terms;
• the landlord’s bargaining position; and
• how strong the assignee’s covenant is (i.e., how likely they are to pay and comply).

This is a key reason to get advice before signing-because you don’t want to assume you’re “off the hook” when you aren’t.

Guarantees And Security

Landlords often require additional comfort, especially where the incoming tenant is a new company or a small operator. Common arrangements include:

• personal guarantees from directors or business owners;
• bank guarantees or bonds; and/or
• updated security documents and enforcement rights.

If there is an existing guarantee, you’ll want clarity on whether it’s discharged, replaced, or continues in some form.

Outgoings, Rent, And Adjustments

Assignments can trigger questions about “who pays what” around the handover date, such as:

• rent paid in advance (apportionment);
• outgoings, rates, utilities, and operational costs; and
• any arrears or credits.

A well-drafted deed (or side agreement) will spell out these adjustments to reduce the risk of post-settlement disputes.

Warranties About The Lease And Premises

The outgoing tenant may be asked to confirm things like:

• the lease is in full force and hasn’t been terminated;
• there are no undisclosed breaches; and
• no side deals exist outside the written lease.

If you give broad warranties, make sure they’re accurate. If there’s a known issue (like an unresolved repair), you may want it disclosed and dealt with up front.

Common Risks And Negotiation Points (So You Don’t Get Caught Out)

Lease assignment isn’t just “sign and done”. A few predictable pressure points tend to come up again and again-especially when the assignment is tied to a business sale timeline.

Landlord Delay Or Refusal

Even where a lease says consent “must not be unreasonably withheld”, there can still be practical delays while the landlord assesses the assignee and negotiates conditions.

To keep things moving:

• prepare the assignee’s information pack early (financials, references, business plan summary);
• check whether landlord legal fees are payable and factor that into your timeline; and
• avoid promising fixed completion dates until you’ve confirmed the consent process.

Ongoing Liability After Assignment

One of the most common mistakes is assuming assignment automatically releases you from all future obligations.

Depending on the lease and deed:

• you might still be liable if the incoming tenant breaches and the landlord enforces a continuing obligation;
• you might have indemnities you’ve agreed to; or
• you might be exposed through a personal guarantee that hasn’t been properly released.

This is why it’s worth getting the assignment documents reviewed, not just signed.

“Change Of Use” And Compliance Issues

If the incoming tenant wants to run a different type of business, the landlord may require the permitted use clause to be amended and may ask for evidence that the new use complies with:

• council rules and consents (depending on the activity and location);
• health and safety obligations under the Health and Safety at Work Act 2015 (for workplace risks); and
• any building or fire safety requirements applicable to the premises.

If you’re the outgoing tenant, you’ll want to make sure any compliance upgrades required for the new use are clearly the incoming tenant’s responsibility (unless you’ve agreed otherwise as part of a broader business sale deal).

Make-Good And Condition Disputes

Many leases require you to “make good” at the end of the lease-often meaning you must remove fit-out, repair damage, and restore the premises to an agreed condition.

Assignment can complicate this because:

• the landlord may still require certain make-good items before consenting; or
• the incoming tenant may want you to leave fit-out in place (and may pay for it as part of the transaction).

It’s important to document what’s staying, what’s being removed, and who pays if something needs fixing later.

Don’t Rely On Templates

Assignment deeds look “standard”, but the details are where risk lives: release wording, guarantees, disclosure of breaches, adjustment mechanics, and consent conditions.

A generic template can easily miss what your lease requires, or fail to protect you on the issues that matter most in your specific transaction.

If you want peace of mind before you sign, a Commercial Lease Review can help you understand what you’re agreeing to and what you should negotiate.

Key Takeaways

• Assigning a lease is a formal transfer where the incoming tenant takes over the lease rights and obligations, usually with the landlord’s written consent.
• A Deed of Assignment is commonly used to record the transfer and set out clear obligations for the outgoing tenant, incoming tenant, and landlord.
• Before you commit to timelines (especially in a business sale), check your lease’s assignment clause for consent rules, landlord conditions, and fee obligations.
• Assignment doesn’t always mean you’re automatically released from liability-make sure the deed deals properly with release wording and any guarantees.
• If the incoming tenant’s business use differs from yours, you may need extra documentation (and potentially a variation) so the use and compliance obligations are clear.
• Make-good and condition issues are a common source of disputes-document what happens to fit-out, repairs, and handover responsibilities.
• Lease assignment documents are rarely “just standard”; getting legal advice early can prevent expensive problems after you’ve moved on.
