Leaving A Partnership in New Zealand

Partnerships are a popular way to start a small business in New Zealand. They’re relatively simple to set up, you can share skills and workload, and you can move fast.

But there’s a catch that many business owners only properly focus on when things get tense: liability.

If you’re planning on exiting a partnership (or you’ve already left and you’re worried about what you’re still “on the hook” for), it’s worth slowing down and getting clear on how leaving a partnership can affect your liability in practice.

Below, we’ll walk you through what can happen to your personal liability when you leave, what steps usually reduce risk, and the key documents and conversations that can make the exit cleaner (and safer) for your business future.

Why Leaving A Partnership Can Be Risky (Even If You’re “Out”)

In a general partnership, each partner can be personally liable for the partnership’s debts and obligations. That’s not just the “fair share” you might have in mind - it can be broader than that.

In New Zealand, general partnerships are governed largely by the Partnership Act 1908. While the law is old, the practical outcome for modern businesses is still very relevant: partners can be exposed to significant personal risk.

Joint And Several Liability (In Plain English)

One of the biggest concepts to understand is that partners can be liable on a joint and several basis. In practical terms, this can mean:

If the partnership owes money, a creditor may pursue any one partner for the full amount (not just a split).
That partner might then need to chase the other partners to recover their share (which can be difficult if relationships have broken down or someone can’t pay).

This is the core reason liability questions come up so often when leaving a partnership: you might leave operationally, but a creditor may still view you as responsible unless the exit is handled properly.

Your Partnership Agreement Matters More Than You Think

If your partnership has a written Partnership Agreement, it should set out what happens when a partner leaves - including payments, notice periods, ownership of assets, restraints, and who carries what risk.

If you don’t have one (or it’s outdated), exits are usually slower, messier, and more expensive because you end up relying on default legal rules and arguing about what was “agreed” verbally.

What Liability Do You Keep After Leaving A Partnership?

When you leave a partnership, there are generally two buckets of liability to think about:

Liability for what happened before you left (historic debts/obligations)
Liability for what happens after you leave (new debts/obligations)

They’re treated differently - and mixing them up is where a lot of risk comes from.

1) Liability For Debts Incurred Before You Left

As a general rule, if the partnership incurred a debt or obligation while you were a partner, you can remain liable for it even after you exit.

This can include things like:

supplier invoices for goods ordered while you were still a partner
tax obligations arising during the period you were a partner (this can be fact-specific, so it’s worth getting advice on your position)
breaches of contract that occurred while you were a partner
claims that relate to events that happened before your exit, even if the claim is made later

This is why exit paperwork often focuses heavily on indemnities (i.e. the continuing partners agree to cover you if something historic comes back). Indemnities can be helpful - but they don’t automatically stop a third-party creditor from suing you.

2) Liability For Debts Incurred After You Left

Ideally, once you leave, you don’t want to be liable for anything the ongoing business does.

However, your exposure after exit can depend on the situation and the specific claim. For example, it may turn on things like:

whether a creditor had notice you left (and whether you were “held out” as still being a partner)
whether you’re still named on contracts, leases, guarantees, or finance arrangements
whether you still appear (publicly) to be a partner (for example, your name is still used in branding, signage, or communications)

In many real-world scenarios, the risk isn’t that you intended to stay connected - it’s that you didn’t fully “disconnect” legally and commercially.

3) Your Personal Guarantees Can Outlive The Partnership Relationship

A very common trap: you might leave the partnership, but you’ve signed a personal guarantee for a lease, loan, supplier account, or equipment finance.

A personal guarantee is usually a separate promise from you personally to pay, even if you’re no longer involved. Leaving the partnership does not automatically cancel that promise.

This is one of the biggest practical drivers of disputes about liability after leaving a partnership - you can be “out” of the business but still exposed if the business defaults later.

How Do You Reduce Liability Risk When Leaving A Partnership? (A Practical Checklist)

There isn’t a single magic step that makes all liability disappear. But there is a clear pattern: the cleaner the exit process, the less likely it is you’ll be dragged back into someone else’s business problems later.

Here’s a practical checklist many small businesses work through when a partner is leaving.

1) Confirm How The Partnership Is Ending (Or Continuing)

Start with the basics: is the partnership continuing without you, or is it ending entirely?

If the partnership is continuing, you’re effectively “retiring” and the business continues with remaining partners (or new partners).
If it’s ending, you may be dissolving the partnership and winding up assets/liabilities.

Where partners are splitting, a written Partnership Dissolution Agreement (or exit deed) can be the document that prevents ongoing disputes about money, assets, and who pays what.

2) Put The Exit In Writing (Even If You’re On Good Terms)

Handshake exits are the kind that come back to bite later - often when someone’s memory “changes” or when a creditor appears.

At a minimum, you typically want a document that covers:

your exit date (and what happens to drawings/profits up to that date)
how the partnership will value and pay out your interest (if applicable)
who owns key assets (equipment, stock, IP, domain names, social media accounts)
what happens with existing liabilities (and any indemnities)
restraint / non-solicitation (if relevant and reasonable)
confidentiality

If you’re unsure what should go in, it can help to read about how to end a business partnership in a way that minimises legal loose ends.

3) Notify Key Third Parties (So You’re Not “Held Out” As A Partner)

One practical step people overlook: notice.

If suppliers, customers, lenders, or landlords still think you’re a partner, you can end up with arguments that you’re still responsible (or that the partnership acted with your authority).

Common parties to notify include:

your bank or lender
major suppliers (especially any with ongoing credit accounts)
your landlord/property manager
insurers
key customers (where you were the relationship-holder)

Exactly how notice should be given depends on your situation and your contracts - but the main goal is to avoid confusion and reduce the chance of “apparent authority” issues.

4) Deal With Contracts You’re Personally Attached To (Don’t Assume They’ll Update Themselves)

To properly manage liability risk when leaving a partnership, you need to identify any contracts where you are:

a party (named as a partner), and/or
a guarantor, and/or
listed as an authorised signatory or account holder

Then you need a plan for each one. Sometimes the remaining partners can take over. Sometimes the other side will require a renegotiation. Sometimes you’ll need a formal legal mechanism (like novation).

Leases, Loans, Suppliers And Staff: The Big Liability Hotspots

In small businesses, partnership liabilities tend to cluster around a few “big ticket” arrangements. If you’re leaving, these are usually the contracts to prioritise.

Commercial Leases (And Personal Guarantees)

If the partnership leases a premises, check:

who is listed as the tenant (the partnership name? all partners individually?)
whether you’ve provided a personal guarantee
whether the lease allows an assignment or change in tenant

If the lease needs to be transferred, the paperwork might involve Assigning a lease or a variation agreed by the landlord. Landlords will often assess the remaining partners’ financial position before agreeing to release you.

Don’t ignore this step. A lease is one of the most common reasons someone leaves a partnership but still faces liability years later.

Loans, Finance Facilities And Security

Debt arrangements are rarely as simple as “take my name off, please”. You may be dealing with:

business loans in the partnership’s name
overdrafts or revolving credit facilities
equipment finance
security documents

Sometimes lenders require personal guarantees from all partners. Sometimes there’s a security interest over business assets. It’s also worth understanding how security arrangements work in NZ, including what a General Security Agreement means for enforcement and risk.

If your name stays on a guarantee or security document, you may still have exposure even if you’ve completely exited day-to-day operations.

Supplier Accounts And Ongoing Trade Credit

Supplier accounts can be a quiet liability risk because they’re often “set and forget” during the life of the business.

Check whether you:

signed credit applications in your personal name
agreed to terms that include personal liability
are still an authorised purchaser on the account

Where possible, get confirmation in writing that:

you are no longer authorised to order on behalf of the business, and
you are released from any ongoing personal obligations (if the supplier agrees)

Employees And Employment Obligations

If the partnership employs staff, you’ll want to be very clear on who the employer is and what happens after you exit. Employment issues can create liabilities through unpaid wages, holiday pay, or disputes.

If the business continues, ensure the ongoing business has proper documentation in place (including an Employment Contract where relevant) and that payroll/account access is correctly transitioned. (Employment and tax issues can be complex, so consider getting advice on your specific circumstances.)

Even if employment claims don’t ultimately land on you personally, they can become costly distractions during a partnership breakup.

Do You Need A Novation, Assignment, Or Something Else?

A lot of people assume that if the remaining partners “agree” to take over responsibility, that’s enough. Internally, that agreement helps. Externally, it often doesn’t.

Here are the main legal mechanisms that come up when untangling liability issues when a partner exits.

Assignment (Common For Certain Rights, But Limited)

An assignment can transfer certain rights (and sometimes obligations, depending on the contract structure and consent requirements), but it doesn’t always release the original party from responsibility.

That’s why, for key contracts, you may need something stronger.

Novation (Often The “Clean Break” Option)

A Deed of novation is commonly used when you want to replace one party with another in a contract so the old party is released and the new party steps in.

This is often relevant for:

customer or supplier contracts
service agreements
certain finance arrangements (subject to lender approval)

Novation usually requires the consent of all parties - which is a good thing, because it creates clarity. But it can take time and negotiation, so it’s worth planning for.

Indemnities (Helpful, But Not A Shield Against Creditors)

It’s common for the remaining partners to indemnify the exiting partner (i.e. promise to cover them if an old liability pops up).

Just keep in mind:

an indemnity is only as good as the person’s ability to pay, and
it doesn’t stop a third-party creditor from pursuing you in the first place

Indemnities are still valuable - they can give you a legal path to recover losses - but they’re not a substitute for dealing directly with key contracts and third parties.

Key Takeaways

Liability after leaving a partnership is a real risk in NZ because partners can be personally liable for partnership debts, including on a joint and several basis.
You can remain liable for obligations incurred while you were a partner, even if a claim or invoice appears later.
Exiting the partnership doesn’t automatically cancel personal guarantees for leases, loans, or supplier credit accounts.
A written exit arrangement (often a dissolution or retirement deed) helps clarify payout, ownership of assets, and internal responsibility for debts.
To reduce risk, notify key third parties and deal proactively with contracts - some situations require formal steps like a novation or lease assignment.
If you’re unsure what exposure you still have, it’s worth getting tailored advice before you sign exit documents or agree to “quick fixes”.
