Heads of Agreement in Family Law: What Is It and Is It Legally Binding?
Umbrella Family Law • June 10, 2026

When separating couples attend mediation, one of the most common outcomes is the creation of a Heads of Agreement. Reaching an agreement at mediation can feel like a huge weight has been lifted, but many people are surprised to learn that a Heads of Agreement is not a legally binding document.
So, what exactly is a Heads of Agreement, and what should you do once you’ve signed one?
What Is a Heads of Agreement?
A Heads of Agreement is a written summary of the arrangements reached between separating parties during mediation or dispute resolution.
It typically outlines the key agreements relating to:
- Property division
- Superannuation splitting
- Spousal maintenance
- Parenting arrangements
- Sale or transfer of assets
- Payment of debts
The document serves as a record of what was agreed during mediation and can help both parties move forward with confidence while their lawyers prepare the formal legal documents.
Is a Heads of Agreement Legally Binding?
No, a Heads of Agreement is NOT a legally binding document.
A Heads of Agreement is generally intended to record the agreement reached during mediation, but it does not create legally enforceable obligations between the parties.
This means that either party may potentially change their position before formal legal documents are prepared and executed.
While a Heads of Agreement can be useful evidence of the intentions of the parties at a particular point in time, it does not provide the same legal protection as properly prepared family law documents.
Why Isn’t a Heads of Agreement Enough?
Many people assume that because they have signed a document at mediation, the matter is finalised.
Unfortunately, that is not the case.
Without formalising your agreement through the appropriate legal process:
- Property settlements may not be legally enforceable.
- Future claims between former partners may remain open.
- Agreed superannuation splits cannot usually be implemented.
- There may be uncertainty about what happens if circumstances change.
For these reasons, it is important to obtain legal advice from a family lawyer as soon as possible after mediation.
How Do You Make a Heads of Agreement Legally Binding?
Once a Heads of Agreement has been reached, each party should obtain independent legal advice.
Your lawyer can review the agreement and advise on the most appropriate way to formalise it.
Depending on your circumstances, this may involve:
Consent Orders
Consent Orders are filed with the Federal Circuit and Family Court of Australia and, once approved, become legally binding court orders.
Consent Orders are commonly used for:
- Property settlements
- Parenting arrangements
- Superannuation splitting
Binding Financial Agreements
In some circumstances, parties may choose to formalise their property settlement through a Binding Financial Agreement (BFA).
A Binding Financial Agreement requires each party to receive independent legal advice before signing and can provide certainty regarding financial matters following separation.
Your lawyer can advise whether Consent Orders or a Binding Financial Agreement is the most suitable option for your situation.
What Should You Do After Mediation?
If you have recently attended mediation and signed a Heads of Agreement, your next step should be to seek legal advice promptly.
A family lawyer can:
- Review the agreement reached
- Identify any potential issues or risks
- Explain your legal options
- Draft the necessary documents
- Help ensure your agreement is properly formalised and enforceable
The sooner this process occurs, the lower the risk of misunderstandings or disputes arising after mediation.
Frequently Asked Questions about Heads of Agreements
Can I rely on a Heads of Agreement if my former partner changes their mind?
A Heads of Agreement may provide evidence of what was discussed and agreed during mediation, but it is not legally binding. If the agreement has not been formally documented through Consent Orders or another legally enforceable mechanism, complications can arise if one party changes their position.
How long after mediation should I formalise the agreement?
It is generally best to obtain legal advice as soon as possible after mediation. Delays can increase the risk of disputes, changes in financial circumstances, or one party reconsidering the agreement.
Can parenting arrangements be included in a Heads of Agreement?
Yes. Parenting arrangements are commonly recorded in a Heads of Agreement. However, if you want legally enforceable parenting orders, you should speak with a lawyer about preparing Consent Orders.
Can a Heads of Agreement include property settlement terms?
Yes. Property settlement terms are often included in a Heads of Agreement following mediation. However, the agreement should be formalised through Consent Orders or another appropriate legal document to provide certainty and enforceability.
Do both parties need separate lawyers?
If you wish to formalise a financial agreement such as a Binding Financial Agreement, each party must obtain independent legal advice. Even where Consent Orders are being prepared, obtaining independent legal advice is strongly recommended.
