Contract Variations: Legal Guidelines for Small Businesses

Table of Contents

In Short

  • A contract variation modifies specific terms of an agreement without replacing the original. This can involve deadlines, payment terms, or services provided.
  • Mishandled variations can lead to disputes, unenforceable changes, and financial loss.
  • Follow legal requirements, document changes thoroughly, and ensure all parties agree to avoid risks.

Tips for Businesses

Always check your original contract for variation clauses and follow the required procedures. Document changes in writing and ensure all parties agree to the variation. If you’re unsure about legalities or the implications, consult a commercial contracts solicitor to ensure your variations are valid and enforceable.

In business, circumstances and deals can quickly change, meaning contractual terms needs to change. Changing a contract can help your small business stay agile and adapt its agreements to the evolving circumstances. Poorly managing contract variations can lead to problems, from disputes to unenforceable changes and financial risks. As such, your small business must take the time to understand what a contract variation is and how to vary a contract correctly. This article explores how to effectively manage written business-to-business contract variations and avoid risk as a small business. 

What is a Contract Variation? 

Your small business can vary a contract by changing specific terms without completely replacing the original agreement. This can help save time and costs. 

For example, you might want to tweak your contract payment terms or move deadline goalposts to meet a client’s requirements.

Variations in a contract provide flexibility but do come with risks. Mishandling changes to a contract can increase the risk of disputes, especially if one party later denies agreeing to the variation. Managing variations correctly is, therefore, vital for your small business. Your small business can vary a contract in multiple ways, depending on the terms of the original agreement. 

For example, you can vary a contract through a written agreement, a deed, or by agreeing to specific changes in writing. However, you must ensure the contract is varied correctly and according to legal rules.

Written variations work best because they clearly document the agreed changes. You can do this in different ways. For example, drafting a formal contract variation amendment or entering into a deed of variation. In some contracts, one party can update terms unilaterally. 

Can Varying a Contract Help a Small Business?

Varying a contract may benefit your business relationships in certain circumstances. For example, when a client asks for a service extension, you can use the opportunity to negotiate better payment terms or secure additional work. Agreeing to reasonable changes with suppliers or partners also shows flexibility and can help foster goodwill. As such, it is essential to understand how to handle variations correctly. Circumstances may also require you to vary your contracts, such as a change in legal rules that affects them.

What Risks Do Contract Variations Pose to Your Small Business?

Variation disputes can be challenging and disrupt your small business significantly. In such cases, the courts will typically examine whether both parties agreed to the variation or whether one party had the right to make the change alone.

You must, therefore, make sure you handle and execute variations properly. Depending on the contract, this might require a deed, a formal written agreement, or an email exchange may suffice. Additionally, variations must involve consideration (something of value exchanged between the parties).

Consideration can take many forms, including the assumption of additional obligations. For example, agreeing to quicker delivery in return for a higher cost could provide sufficient consideration. To minimise disputes and arguments around valid consideration, you can formalise your contract variations as deeds or include nominal consideration amounts, such as a payment of £1.

What Key Steps Should Your Small Business Take to Prevent Risk When Varying Contracts?

Here are some key steps your business can take to prevent risk when varying a contract:

  • to reduce risks, you should always check your original contract to see what it says about variation and any formalities you need to follow. Many agreements include specific procedures for making variations, such as terms requiring the parties to agree to a variation in writing;
  • a variation must comply with any formalities set out in the original contract or required by law for a variation to be valid. If the contract includes a clause requiring variations to be in writing, for instance, verbal or informal changes will not be enforceable;
  • you should make sure all parties to the original contract are a party to the variation where required; and
  • you should also make sure that changes are clearly documented and mutually agreed upon by all parties. You should carefully review potential ‘consequential amendments’. For example, how a variation might affect other parts of the contract or related agreements. Working with a commercial contracts solicitor can help you with this and ensure you avoid pitfalls such as conflicts and other unintended consequences arising from the variation agreement. 

It is essential to take your time to address contract variations correctly and thoroughly. Even if you are in a rush to change a project’s terms (for instance, at a client’s urgent request), you should carefully consider the necessary steps to vary your contract correctly to ensure the variations are legally sound and enforceable.

Frequently Asked Questions

What is a contract variation?

A contract variation is when your business and another party agree to change specific contract terms while keeping the rest of the agreement as is. For example, you might agree to tweak your delivery times or payment terms but keep the rest of your agreement the same. 

Why is it important to document contract variations?

Documenting variations ensures a clear record of the agreement. This can help prevent misunderstandings or disputes and make the changes legally enforceable. Business owners can seek legal advice from a commercial contracts solicitor if they need support.
