Are verbal contract changes legally binding?

We agreed on updates during a call, but nothing was signed—does that still count?

Answer

Sometimes, but often not. Verbal contract changes can be legally binding if both parties clearly agree to the new terms. However, they are much harder to enforce, especially if nothing is written or signed.

In many cases, the original written contract still controls unless the changes are properly documented.

When can verbal changes be valid?

Verbal changes may be valid if there is clear agreement between both parties and the basic elements of a contract are present, like offer and acceptance.

In some cases, there must also be "consideration," which means something of value is exchanged. For example, one side may agree to do more work or accept different terms in return.

However, even if valid in theory, verbal changes can be difficult to prove. Without written evidence, it may come down to conflicting accounts of what was said.

Some contracts also require all changes to be in writing. If your agreement includes this type of clause, verbal updates are usually not enforceable.

When are verbal changes not enforceable?

Some types of agreements must be in writing under certain laws (often called the statute of frauds). In those cases, verbal changes may not be valid, even if both sides agreed.

Verbal contract changes may also not hold up if:

The contract requires written amendments.
There is no clear proof of agreement.
There is no exchange of value (in some situations).

Why is writing still the safer option?

Written amendments provide clear proof of what was agreed and help avoid disputes. They also make it easier to show that both parties accepted the changes.

In some cases, writing is not just safer—it is required by law.

What to do next...

Check if your contract requires changes to be in writing.
Write down the agreed changes as soon as possible.
Confirm the terms with the other party in a clear format.
Have both parties sign a formal amendment.

What to consider in your specific situation

While verbal agreements can sometimes count, your situation may depend on several factors.

Whether your contract includes a "no oral changes" clause.
The type of contract and applicable legal requirements.
How clearly the verbal terms were agreed upon.
Whether there is any written follow-up (like emails).
The importance of the changes to your business.
The risk of disagreement between the parties.
