Do We Really Need a Contract?

Bret Gower | June 2, 2026

It is a common question for business owners: do we really need a contract, or can we rely on trust?


The short answer is that, while many arrangements are legally valid without being written down, relying on informal agreements can expose your business to unnecessary risk.

Do We Really Need a Contract?

Verbal agreements vs written contracts


In New Zealand, a verbal contract can still form a legally binding agreement if the essential elements are present.


However, the difficulty is not whether a contract exists – it is whether you can prove what was agreed if something goes wrong.


Without written evidence, disputes often come down to one person’s word against another’s. By contrast, a written contract provides clarity, certainty and a clear record of each party’s rights and obligations.


Why contracts matter for businesses


A well-prepared business contract is not about formality – it is about protecting your position and making your business easier to run.


Clear terms and conditions help to:


  • set expectations from the outset
  • define payment terms and avoid disputes over invoices
  • clarify responsibilities and delivery obligations
  • provide a framework for resolving issues
  • protect your business if the other party does not perform


They also give you a stronger footing if you need to enforce your rights, rather than trying to reconstruct an agreement after the fact.



Reducing risk and protecting value


As your business grows, so does your exposure. A supplier failing to deliver or a customer failing to pay can have knock-on effects across your operations.


Having a clear commercial contract in place helps manage those risks and reduces the likelihood of disputes arising in the first place. It also demonstrates that your business is well-structured, which can be important when seeking finance or preparing for sale.


Keep it simple and practical


Contracts do not need to be complicated. In many cases, a clear set of terms and conditions or terms of trade will be sufficient, provided they reflect how your business actually operates.


The key is that the agreement is clear, commercially sensible, and understood by both parties.


So, do you really need a contract?


For low-risk, everyday transactions, an informal arrangement may be enough.


But for anything involving real value, ongoing obligations or potential liability, a written business contract is a practical and commercially sensible safeguard.


If you are unsure whether your current arrangements adequately protect you, it is worth getting advice before issues arise.
