The concept of contract certainty holds significant importance in agreements and transactions. For businesses operating under the jurisdiction of UK law, understanding what certainty means in contract law is vital to ensure valid and binding contracts. 

In this article, we'll delve into the key aspects of contractual certainty and why it matters to small business owners.

What is certainty in contract law?

Certainty in contract law refers to the clarity and precision of the terms and conditions within a contractual agreement. All parties involved in a contract need to fully understand and interpret its terms. A contract should be a complete and final agreement, leaving no room for ambiguity or misunderstanding. 

Do contracts need certainty?

Certainty is the cornerstone of a legally binding contract. Without it, contracts are susceptible to disputes and legal challenges as to their validity. Ensuring your contract has certainty is important to protect your interests and maintain trust with partners, customers and suppliers. Contracts which are too vague or not capable of judicial interpretation may be void by reason of uncertainty.

Contract certainty requirements

Contract certainty entails several aspects as follows:

  • Agreement of all terms – all parties must agree on every aspect of the deal, including price, delivery, payment terms and any special conditions etc, and these should all be explicitly set out in the contract (this is very important as otherwise there can be a lack of certainty as to the parties’ intentions)
  • Written contract – in many cases, contracts should be in writing to provide a clear record of the agreement reached and to act as an ongoing reference point as the business relationship develops
  • Clear drafting – all terms and conditions should be explicitly stated (and not vague and uncertain) within the contract, leaving no room for interpretation

Contract certainty timescales

In contract law, specific timescales play an important role in ensuring contractual certainty. Any deadlines or timescales specified in a contract should be clear, unambiguous and capable of enforcement. 

Failure to specify deadlines precisely can lead to disputes and legal challenges. This is particularly the case when the timescales are at the heart of the contract, such as for example delivery deadlines or service of notice deadlines.

Avoid vague terms 

Confusion often arises when contract terms and definitions are vague or open to multiple interpretations. You may find yourself in disputes if you haven't clearly defined your agreements. 

How is contract certainty governed?

In the UK, contract certainty is primarily governed by English contract law. English contract law sets the framework for how contracts are formed, interpreted and enforced.
