- It provides a practical explanation of legal risks, evidentiary issues and how conduct can unintentionally create binding obligations.
Tips for Businesses
Do not assume an unsigned contract is not binding. Avoid starting work until agreements are finalised. Use “subject to contract” wording during negotiations. Keep clear records of communications and conduct, and ensure contracts are properly signed to reduce uncertainty and legal risk.
An unsigned contract is a written agreement that has not been formally executed, but it may still be legally binding if the parties’ actions show they accepted the terms. For your business, this creates real risk, as you could be bound by obligations you assumed were not final, or struggle to enforce terms without clear evidence of agreement. Courts focus on conduct, intention and performance rather than signatures alone, making informal dealings legally significant. This article explains when an unsigned contract can be binding and the risks you should manage.
What is a Commercial Contract?
A commercial contract is a legally binding agreement between two businesses. It may be in writing, oral or partly both. A typical example is when one party requests a service in return for a specific sum of money.
Is it Common for Commercial Contracts to Be Unsigned?
It is not standard practice for you to proceed without signing a contract. However, in fast-moving commercial environments, you may begin performing your obligations before formally signing the contract.
While it is still unusual for you to follow agreed contract terms without signing a binding document, this can happen in practice. For example, you or the other party may simply overlook signing the contract due to time pressures or competing priorities.

Can an Unsigned Commercial Agreement Bind My Company?
Yes, but only in limited circumstances. In most situations, if you do not sign a contract, it is typically not legally binding and a court may find that no agreement was formed. However, in some cases, a court may still find that the contract terms have legal effect.
Some of the most common scenarios are below.
Can Your Conduct Make an Unsigned Contract Binding?
A court will consider your actions and whether you have acted in line with the agreement. This is because a court may treat a contract as binding if it believes you intended to follow its terms, even if you did not sign it.
For example, if your company receives goods or services under the terms of an unsigned contract and makes payment according to the agreed schedule, a court may find that you accepted the contract through your conduct. Similarly, if you and the other party perform your obligations for several months without signing the document, this pattern of behaviour may indicate that you agreed to be bound by its terms.
Can a Verbal Agreement Be Legally Binding?
If you do not have a written document, you cannot record a signature. However, verbal contracts can still be legally binding. The main issue is proving exactly what you and the other party agreed, as there is no written document to refer to.
A verbal contract (also known as an oral or parol contract) is when you agree to terms through spoken words rather than in writing. Even so, the agreement must still include the essential elements of a contract: offer, acceptance, consideration and an intention to create legal relations.
As with unsigned written contracts, a court will also consider your conduct after the agreement. For example, how you and the other party acts can help show agreed terms.
Therefore, you are in a binding contract in England, whether in writing or verbal, regardless of signing anything.
Exceptions
However, you must sign some commercial agreements for it to be legally binding.
For example, this can include agreements to transfer shares or assign intellectual property rights. These requirements depend on the type of contract and the applicable legal rules.
As a result, you should seek legal advice if you are unsure whether a signed or unsigned agreement will bind your business, as some contracts have strict formal requirements while others do not.

Nevertheless, this will not stop them from declaring contract arrangements legally binding when the parties’ conduct suggests so. This is not a simple area to navigate, and, because of this, many business owners obtain expert legal advice regarding any unsigned commercial deal.

Frequently Asked Questions
A court will look at all available evidence to determine whether you and the other party intended to be bound. This may include email correspondence, invoices, delivery notes, payment records and witness evidence. If you have been invoicing or making payments in line with the terms of an unsigned agreement, or referring to it as binding in your communications, this can support the existence of a contract. The more consistently both parties act as if the agreement applies, the stronger the case for enforcement.
It can be difficult to avoid liability once you begin performing under an unsigned contract. If you accept goods, make payments or otherwise act in line with the terms, a court may find that you accepted the agreement through your conduct, even if the performance was unintentional. However, this will depend on the circumstances. For example, if you can show there was a genuine mistake about a key term, or that you clearly communicated that you did not accept the contract, you may be able to argue that it is not binding.
Unsigned contracts create uncertainty. In most cases, they are not legally binding, which can lead to disputes about whether an agreement exists and what terms apply
You should ensure both parties sign the contract before starting work. This provides clear evidence of agreement and reduces the risk of uncertainty or enforcement issues.
