When Do Terms and Conditions Become Effective?

Table of Contents

Drafting comprehensive terms and conditions is crucial when embarking on new business ventures and ensuring good business relationships. However, the effectiveness of these terms hinges on a critical question: at what point does a customer accept them, and when does a contract become legally binding? This article aims to unravel the intricacies of this process, shedding light on the various forms of acceptance and their implications for businesses in New Zealand.

What Are the Terms and Conditions?

Terms and conditions are the legal backbone of business agreements, setting out the rights and responsibilities of the parties involved, which shapes the relationship between you, your customers, and suppliers. These agreements, often called contracts, govern the dynamics of your business operations. A well-crafted set of terms and conditions is essential for the smooth functioning of your business.

The specifics of your terms and conditions depend on the industry in which your business operates. For example, they could include the following:

  • clauses about goods and services your company provides;
  • delivery mechanisms;
  • payment terms;
  • termination procedures;
  • intellectual property protection; and
  • dispute resolution processes. 

Terms and conditions must comply with specific conditions to become operational. 

Determining When Terms and Conditions Take Effect

One fundamental aspect that determines the effectiveness of terms and conditions is the clarity of language used. Courts generally favour clear and unambiguous terms, ensuring that parties are fully aware of their obligations. 

Ambiguities can lead to disputes, making it essential for businesses to communicate in an easily understandable manner by the average consumer.

Acceptance Mechanisms

Understanding when a customer accepts your terms and conditions is paramount, as it marks the commencement of the contract. A legally accepted contract requires both parties to fulfil their obligations outlined in the terms. Without clear acceptance, the contract is not legally binding, and the clauses will not be enforceable.  

There are two primary forms of acceptance, which we will explore below.

1. Express Consent

The most straightforward method is to obtain express consent from your customers. This involves clear communication where customers explicitly state their acceptance. Physical documents, presented independently or attached to service quotes, can serve this purpose. Electronic delivery, including email, is also acceptable.

Websites often employ this method by displaying terms and requiring customers to confirm their agreement by clicking a checkbox. It is crucial to ensure customers have adequate time to review the terms, even if they may not necessarily read every detail.

2. Implied Consent

Implied consent arises when it can be inferred from the parties’ conduct. For example, if a customer instructs you to proceed with your services, their conduct may be construed as accepting your terms and conditions.

Websites may use an agreement where users are deemed to accept terms by accessing the site. However, caution is advised in such situations, as explicit acceptance provides a more secure legal footing.


The timing of when terms and conditions take effect depends on the context of the transaction. 

In pre-contractual negotiations, parties engage in discussions that may or may not lead to a formal agreement. During this stage, invitations to treat and offers are distinct. An invitation to treat is an invitation for potential negotiations, while an offer is a clear proposal to enter into a contract. Only upon acceptance of the offer do the terms and conditions become binding.

In online transactions, click wrap and browse wrap agreements are two common mechanisms. 

  1. clickwrap agreements require users to actively click “I Agree,” signalling explicit acceptance of the terms and conditions, meaning they start to take effect from that point onward; or
  2. in contrast, browsewrap agreements rely on users’ continued website use to indicate acceptance, making them less secure. 

Other Key Considerations 

In New Zealand, consumer transactions have additional layers of protection under the Consumer Guarantees Act 1993. This legislation protects consumer rights, where businesses must ensure fair and reasonable contract terms.

Unfair contract terms can face legal scrutiny, including those unclear or disproportionately favouring one party. Striking a balance between protecting consumers and allowing businesses reasonable contractual freedom is crucial for terms and conditions to take effect. 

Practical Tips for Consumers and Businesses

For consumers, the key lies in reading and understanding the terms and conditions before agreeing.  Seeking legal advice when in doubt can prevent future complications. On the other hand, businesses should focus on drafting clear and transparent terms. 

Providing a summary or FAQ section can assist users in grasping the essence of the agreement.

Key Takeaways 

Terms and conditions are vital components of a contract, and they can only take effect when the other party, such as a customer, explicitly or implicitly accept them through their actions. Without a valid acceptance, the legal system does not acknowledge the existence of a valid contract that is legally binding.
