Ending A Partnership? Here’s Why You’ll Need A Partnership Dissolution Agreement. (2026 Updated)

Partnerships can be a great way to start and grow a business in New Zealand. You get shared skills, shared costs, and (hopefully) shared wins.

But when a partnership ends, things can get messy surprisingly fast - even if you’re still on good terms.

This 2026 update reflects the practical reality we’re seeing for Kiwi businesses today: more partnerships are operating with online tools, shared digital assets, and informal arrangements that feel “fine” until someone exits. If you want to protect your business (and your relationship with your former partner), a properly drafted dissolution agreement is one of the most important documents you can put in place.

Below, we’ll walk you through what a partnership dissolution agreement is, when you need one, what it should cover, and the common issues it can prevent.

What Is A Partnership Dissolution Agreement (And What Does It Actually Do)?

A partnership dissolution agreement is a written agreement that sets out how you and your partner(s) will end the partnership, including who gets what, what happens to debts, and what each person can (and can’t) do after the split.

In plain English: it’s the “exit plan” for your partnership.

Even if your partnership is informal (for example, you never signed a partnership agreement when you started), it’s still smart to document how the partnership is ending. That’s because a lot of obligations don’t automatically disappear just because you’ve “agreed to move on”.

Why This Matters In New Zealand

In NZ, partnerships aren’t a separate legal person like a company. This generally means partners can be personally responsible for the partnership’s obligations.

So if the partnership took on debts, signed up to service contracts, or owes money to suppliers, you’ll want to be very clear about:

• what the partnership owes;
• who is responsible for paying it; and
• what happens if one partner doesn’t pay.

A dissolution agreement won’t magically erase liability to third parties (like banks, landlords, suppliers or customers), but it can create clear rights between partners - and reduce the risk of disputes later.

When Do You Need A Partnership Dissolution Agreement?

You’ll usually want a partnership dissolution agreement whenever one of these situations happens:

• One partner is leaving but the business will continue in some form (for example, the remaining partner continues as a sole trader, or you bring in a new partner).
• You’re both ending the business and winding everything up (selling assets, paying debts, closing accounts).
• You’re selling the partnership business to a third party and need to document how proceeds and responsibilities are handled.
• The relationship has broken down and you want a clean, enforceable outcome instead of an ongoing argument.

“We’re Still Friends - Do We Really Need This?”

Yes, in most cases.

It’s common for partners to say, “We trust each other” or “We’ll just split everything 50/50”. The issue is that a partnership breakup isn’t just about intentions - it’s about practical details, timing, and risk.

For example:

• Who keeps the client list and who can contact those clients?
• What happens to the business name, website, and social media accounts?
• If there’s a tax bill or chargeback later, who covers it?
• If there are warranties, refunds or ongoing customer obligations, who handles them?

These are the kinds of issues that can turn a friendly split into a costly one.

What Should A Partnership Dissolution Agreement Cover?

There’s no one-size-fits-all document, but a strong dissolution agreement usually covers the following areas in a clear and practical way.

1) The Dissolution Date And What Happens Next

You’ll want to set out:

• the effective date of dissolution (when the partnership ends);
• whether the partnership is winding up entirely, or continuing under someone else; and
• any transition period (for example, a 30-day handover of admin, client work, or supplier relationships).

2) Assets: Who Gets What?

This is where many disputes start - because “assets” aren’t just cash in the bank.

A dissolution agreement should deal with tangible and intangible assets, such as:

• money in bank accounts;
• stock, tools, equipment, vehicles;
• leasehold improvements (fit-out, signage);
• domain names, websites, email addresses, social media pages;
• branding (logos, design files);
• customer lists, pricing lists, supplier arrangements;
• intellectual property (like content, software, training materials).

If the business is being sold, it should also cover how the sale price is allocated and when each partner gets paid.

If you’re unsure whether the business is being sold as a “going concern” or just shutting down, it helps to clarify the commercial intent early - the concept of going concern often comes up in business sales and transitions.

3) Debts And Liabilities (The Part People Forget)

A key purpose of a dissolution agreement is allocating responsibility for liabilities, including:

• supplier invoices and outstanding bills;
• subscriptions (software, advertising, phone plans);
• customer refunds or chargebacks;
• loan repayments and guarantees;
• tax obligations and accounting costs;
• lease obligations (including make-good clauses).

It’s also common to include an indemnity clause, which is a promise that if one partner gets stuck with a debt the other partner agreed to pay, they’ll reimburse them. This is similar in concept to how risk is allocated in an indemnity clause.

4) Clients, Ongoing Work, And Handover

If your partnership provides services (consulting, trades, creative work, professional services), you’ll want to be crystal clear about:

• which client engagements are completed by the dissolution date;
• which work in progress will be finished (and by whom);
• whether one partner takes over certain clients;
• how revenue is split for partially completed work; and
• what happens to client deposits or prepaid work.

It’s also worth documenting how you’ll communicate the split to clients. A well-managed transition reduces reputational risk and avoids confusing customers.

5) Restraints, Non-Solicitation, And Using The Business Name

This is one of the most sensitive areas.

Many partners assume they’re both free to compete immediately. That can be true - but it can also be a recipe for conflict if you’re both chasing the same clients, using similar branding, or arguing about who “owns” the goodwill.

A dissolution agreement can include:

• a restraint of trade (in limited, reasonable circumstances);
• a non-solicitation clause (e.g. not approaching certain clients for a period);
• rules about who can use the business name, social handles, and brand assets; and
• confidentiality obligations (client lists, pricing, supplier terms).

If restraint clauses are too broad, they may be difficult to enforce - so it’s worth getting tailored legal advice rather than using a template. The enforceability depends heavily on what’s reasonable in your industry and situation.

6) Employee And Contractor Arrangements

If the partnership employed staff or engaged contractors, you’ll need a plan for:

• who becomes the new employer (if the business continues);
• what happens to accrued entitlements (annual leave, alternative holidays, etc.);
• who communicates with staff, and when; and
• what contracts need to be updated or reissued.

If the business will continue under one partner, you may need updated Employment Contract documents that reflect the new employer and the right terms for your team.

If you’re continuing with contractors, you might also need a clear Contractor Agreement so everyone understands the new relationship and expectations.

7) Settlement, Releases, And “No Future Claims”

A dissolution agreement often includes:

• a statement that each partner releases the other from claims related to the partnership (with appropriate carve-outs);
• a record of any final payments (for example, one partner paying the other for their share); and
• confirmation that once the agreed steps are completed, the matter is settled.

This “clean break” function is one of the biggest reasons to formalise your breakup in writing.

Common Partnership Breakup Problems A Dissolution Agreement Can Prevent

Most partnership disputes aren’t caused by one huge dramatic event. They’re caused by dozens of small unclear things that add up over time.

Here are some of the most common issues we see - and how a dissolution agreement helps.

Disputes Over Money In The Bank

If there’s cash sitting in the partnership account, you’ll want to be clear about:

• what bills must be paid first;
• whether one partner is reimbursed for expenses they covered personally; and
• how remaining funds are split.

Without a written plan, one partner withdrawing funds can quickly be seen as “stealing” - even if they thought it was fair.

Arguments About Who Owns The Brand And Website

Digital assets are now some of the most valuable assets in a small business.

It’s common for:

• one partner to have registered the domain name personally;
• social accounts to be tied to one person’s email/phone;
• design files to be stored in one person’s cloud account; and
• customer data to live in one person’s CRM.

A dissolution agreement can set out a practical handover process (including logins, transfers, and deadlines) so the business isn’t held hostage by account access problems.

Ongoing Liabilities That Show Up After The Split

Some liabilities appear later, such as:

• warranty claims;
• late supplier invoices;
• rent outgoings adjustments;
• tax reassessments;
• customer refunds (especially for online sales).

Allocating responsibility in advance reduces the chance you’ll be stuck paying for something you didn’t agree to.

One Partner Keeps Trading Under The Same Name

If one partner keeps operating and the other leaves, you’ll want to avoid confusion in the market.

For example, if your old partnership had quality issues near the end, the leaving partner may want reassurance that they won’t be blamed for future work.

A dissolution agreement can cover:

• how the business is described publicly after the split;
• who is responsible for past work and future work; and
• any disclaimers or notices to clients where appropriate.

How To Approach A Partnership Dissolution The “Right” Way

If you’re in the middle of a partnership breakup, it can feel overwhelming - especially if you’re also trying to keep the business running.

Here’s a practical approach that usually helps partners move forward without unnecessary drama.

Step 1: Get Clear On The Facts (Not Just The Feelings)

Before you negotiate anything, gather the basics:

• bank statements and current balances;
• a list of debts and creditors;
• the lease and any key supplier contracts;
• a list of physical assets and approximate values;
• logins/ownership details for key digital assets; and
• any agreements you already have in place.

This is also a good time to check whether you already have a written Partnership Agreement - if you do, it may set out a process for exits and dispute resolution.

Step 2: Decide Whether The Business Will Continue

There’s a big difference between:

• ending the partnership and shutting down the business; versus
• ending the partnership but continuing the business under one person (or a new structure).

If someone is continuing, it’s often worth considering whether the business should move into a company structure for clearer ownership and liability boundaries. In that case, documents like a Company Constitution or a Shareholders Agreement may become relevant if there will be multiple owners going forward.

Step 3: Document The Agreement Properly (Don’t DIY The Legal Part)

It’s tempting to download a free template and “just sign something”. But partnership dissolutions are one of those areas where small drafting gaps can create big problems later.

A properly drafted dissolution agreement should reflect:

• your actual assets and liabilities (not generic placeholders);
• how your business operates (online, in-person, service-based, product-based);
• who is taking what risk; and
• what happens if something goes wrong after the split.

Spending the time to get the agreement right now can save you months of disputes later.

Step 4: Follow Through On The Practical Steps

Signing the dissolution agreement is only part of the job. You’ll also need to action what it says.

That may include:

• notifying suppliers and customers (where appropriate);
• closing or transferring bank accounts;
• updating signatories and payment authorities;
• transferring domains, IP, social accounts, or phone numbers;
• finalising accounting and tax returns; and
• ending or assigning leases and contracts.

If your partnership has a commercial lease, it’s especially important to confirm whether the lease can be assigned, surrendered, or needs landlord approval - this is often a major source of “surprise liability” after a breakup.

Key Takeaways

• A partnership dissolution agreement sets out how you and your partner(s) will end the partnership, split assets, allocate debts, and manage the transition.
• Even if your partnership was informal or you’re splitting on good terms, documenting the breakup can prevent disputes about money, clients, digital assets, and liabilities that arise later.
• A dissolution agreement should typically cover the dissolution date, asset division, debts and indemnities, client handover, confidentiality, restraints/non-solicitation, and staff/contractor arrangements.
• Partnerships can create personal liability exposure, so it’s important to be clear about who is responsible for what - and what happens if something goes wrong after the split.
• Generic templates often miss key business-specific issues (like online accounts, IP, and ongoing customer obligations), so getting tailored legal help is usually a smart investment.
