A Memorandum of Understanding (MOU) is a formal document that sets out the key principles of a proposed business arrangement between two or more parties. It is often used in Australian commercial law to record the intentions of the parties before entering into a legally binding contract.
An MOU is sometimes called a Letter of Intent. It is a practical tool used by businesses to clarify the scope of cooperation, responsibilities, and shared goals at the early stages of a commercial relationship.
In this article, our business contract lawyer will help you to understand MOUs. We are also able to help Australians who may need a lawyer to draft one.
Key Takeaways
An MOU records the intent of the parties and outlines key commercial principles.
It is usually not legally binding, but may become binding if drafted incorrectly.
It helps parties clarify roles, responsibilities, and next steps before entering into a contract.
Legal advice ensures your MOU reflects your intentions and protects your business.
When to Use a Memorandum of Understanding
An MOU is a pre-contractual document. It helps the parties express their willingness to proceed with a deal while allowing flexibility before committing to a binding contract.
You may want to use an MOU if you:
are not yet ready to enter into a legally binding agreement
want to outline a mutually beneficial business relationship
wish to record the mutual goals of a commercial partnership
need a framework for negotiation or due diligence
An MOU provides structure and clarity for discussions. It can serve as the starting point for contract negotiations, ensuring all parties are aligned before moving forward.
Is a Memorandum of Understanding Legally Binding in Australia?
MOUs are not usually legally binding, but in some cases, they can be.
Under Australian contract law, an MOU will only be legally binding if it contains all the elements of a contract:
an offer and acceptance
consideration
intention to create legal relations
certainty of terms
This distinction can make MOUs risky because they:
may not be legally binding (even if you want them to be), or
may be legally binding (when you don’t intend them to be).
That’s why it’s essential to have a lawyer review or draft your MOU — to make sure it reflects your intentions clearly.
When an MOU Is Not Legally Binding
An MOU will not be legally binding if it does not include all the elements of a binding contract.
In many cases, this is intentional. Businesses often use an MOU to record the principles of an agreement without creating enforceable obligations.
Sometimes, a non-binding MOU is beneficial because:
it allows the parties to walk away or change their intentions without penalty
it promotes trust and collaboration before legal commitments are made
To ensure an MOU is not legally binding, it should include a clause such as:
“This document is not intended to be legally binding or legally enforceable.”
This makes the parties’ intentions clear.
When an MOU Becomes Legally Binding
An MOU may be legally binding if:
it includes all the elements of a contract; or
the language used demonstrates an intention to be bound.
For example, if the MOU sets out commercial terms such as price, duration, or exclusivity, a court may interpret it as creating enforceable obligations — even if the parties didn’t intend it to.
What Should Be Included in an MOU?
The process of preparing an MOU often begins with each party proposing its ideal terms. The goal is to create a shared understanding before formalising the agreement in a contract.
An MOU generally includes:
a description of the parties
the date of the document
a description of the project or arrangement
the scope of the MOU and each party’s role and responsibilities
a statement that the document is one of intent only
a statement that the document is not legally binding (if intended)
an execution clause for the parties to sign
While not legally binding, an MOU is an important step in a commercial relationship. It requires careful drafting to ensure it accurately records the parties’ commercial understanding and avoids creating unintended legal obligations.
To create an MOU, the parties must first agree on key commercial principles. This provides a roadmap and clarity on priorities before formal contracts are prepared.
The Difference Between an MOU and a Contract
The key differences between a Memorandum of Understanding and a contract are:
Memorandum of Understanding
Contract
Usually not legally binding
Always legally binding
Expresses an intent to enter into a future contract
Expresses the full extent of the agreement
Used to negotiate or record commercial principles
Typically drafted in general terms
Contains specific and enforceable obligations
Definitively states the commercial terms
An MOU can be a useful step before a contract because it documents preliminary terms without committing the parties to a binding arrangement.
For example, a retailer and manufacturer might use an MOU to outline how they will collaborate to achieve mutual commercial goals before negotiating pricing and supply terms under a later contract.
Why You Should Have a Lawyer Draft Your MOU
Although an MOU is not always binding, the language used can have legal consequences.
If the terms suggest a binding commitment, a court could enforce it even if the parties intended otherwise.
A commercial lawyer can:
ensure the document reflects your intentions
include appropriate disclaimers and binding/non-binding clauses
prepare an MOU that supports negotiation while protecting your position
