Don’t Waive Your Rights! Understanding Legal Privilege in Family & Surrogacy Law

Legal professional privilege is one of those legal concepts that sounds technical, but it protects something very practical and very important: the confidentiality of communications between a lawyer and a client.

In family law and fertility law matters, that protection can make a real difference. It applies in obvious settings such as litigation, but it also matters in more cooperative legal processes, including surrogacy arrangements, where everyone may be working towards the same outcome.

The key point is simple. Legal professional privilege belongs to the client. It is the client’s right to keep certain legal advice and related documents confidential. But that protection can be lost if privileged material is shared too freely.

What is legal professional privilege?

Legal professional privilege is a protection recognised under the common law. It safeguards confidential communications and documents between a lawyer and a client from being disclosed to others.

At its core, the rule exists so clients can speak openly with their lawyers. People need to be able to seek legal advice honestly and completely, without worrying that their private communications will later be handed over to someone else.

That is why privilege is such a fundamental part of the legal system. It supports candid advice, proper preparation, and fair legal representation.

For a general overview of legal rights and obligations in Australian legal matters, the Australian Government Attorney-General’s Department provides useful public information on the legal system.

Who does the privilege belong to?

This is where many people get tripped up. Even though the communication is with a solicitor, the privilege does not belong to the lawyer. It belongs to the client.

That means it is the client’s right to claim, preserve, or potentially waive that protection.

Lawyers should be careful not to do anything that could waive a client’s privilege. But clients also need to understand their own role. A person can unintentionally undermine their own protection by forwarding advice, sharing documents, or discussing legal communications with third parties without first checking whether it is safe to do so.

In other words, privilege is valuable, but it is not automatic forever. It needs to be protected.

The dominant purpose test

Not every document connected to a legal matter is automatically privileged. The central question is whether the communication or document was created for the dominant purpose of one of the following:

• giving or receiving legal advice, or
• use in existing or anticipated litigation.

This is often called the dominant purpose test.

If that test is satisfied, the communication or document is generally protected by legal professional privilege and should not be disclosed to a third party.

The idea of “dominant purpose” is important. A document may have several purposes, but the main or prevailing purpose is what matters. If the main reason it was created was to obtain legal advice, or to prepare for litigation, privilege may apply.

The Federal Circuit and Family Court of Australia is also a useful reference point for people involved in family law disputes, particularly where questions arise about court procedure and disclosure obligations.

Why privilege matters so much

Privilege protects more than just a letter or an email. It protects a client’s ability to seek legal advice candidly. That matters in emotionally charged and high-stakes matters such as:

• parenting disputes
• property settlements
• fertility law matters
• surrogacy arrangements
• other family law proceedings

If privileged material is disclosed when it should not be, the consequences can be serious. A client may lose the right to keep that material confidential, and in some situations the loss of privilege may extend beyond a single document.

That is why caution matters. Even where disclosure seems harmless, it may not be.

Privilege in litigation is usually easier to spot

In litigation, the risks are often more obvious. When parties are opposed to each other in a dispute, they are naturally more guarded about what they share. Most people understand instinctively that legal advice obtained in a contested matter should not be handed to the other side.

Because the conflict is clear, people are often more careful. They think before forwarding documents. They ask before disclosing advice. They recognise that communications with their solicitor are likely to be confidential.

Even so, mistakes can still happen. A well-intentioned email chain, a copied message, or an attachment sent without checking can create problems very quickly.

Non-litigious matters can be riskier than people realise

Where things become especially tricky is in matters that are not overtly adversarial.

In non-litigious contexts, parties may feel comfortable with one another and may be working cooperatively. That can create a false sense of safety around information sharing.

Surrogacy is a very good example.

In a surrogacy arrangement, the intended parent or intended parents and the surrogate are usually independently represented. Each party has their own lawyer, but they are often working towards the same broad goal. There may be goodwill, openness, and a genuine desire to keep things moving smoothly.

That dynamic can make it tempting to share legal advice received from one’s own lawyer with the other party, especially if it seems helpful or efficient. But the fact that the matter is cooperative does not mean privilege disappears.

If a communication or document satisfies the dominant purpose test, then sharing it with the other side could amount to a waiver of privilege.

What is a waiver of privilege?

Waiver of privilege happens when the protection over privileged material is lost.

This can occur intentionally or unintentionally.

Intentional waiver is fairly straightforward. It happens when a client knowingly discloses privileged advice or documents to another person.

Unintentional waiver is the more dangerous trap because it can happen through ordinary, everyday conduct. For example:

• forwarding legal advice to the other side
• sharing a solicitor’s written comments to “speed things up”
• circulating legal documents beyond those who need to see them
• discussing confidential advice in a way that reveals its substance

People often assume that because they did not mean to give up privilege, it will remain intact. Unfortunately, that is not always how it works.

The domino effect: losing privilege over associated material

One of the most important warnings in this area is that a waiver may not stop with a single document.

In some circumstances, disclosing one privileged communication can affect privilege over related documents or information as well. That is why lawyers are often very cautious about even limited disclosure.

Once privilege is compromised, it can create a much larger problem than first expected. A seemingly minor email or attachment may have consequences for the broader chain of advice, related drafts, or associated communications.

This is one reason legal professional privilege should never be treated casually, even in friendly or collaborative legal matters.

Practical steps clients should take

The safest approach is a simple one: if in doubt, check with a lawyer before sharing anything.

That includes documents, screenshots, emails, letters, file notes, and even summaries of legal advice.

Some sensible habits include:

• Do not forward legal advice to the other party without legal clearance.
• Do not assume cooperation means disclosure is harmless.
• Keep solicitor communications confidential unless advised otherwise.
• Ask before sharing documents that were prepared for legal advice or litigation.
• Be careful in group emails and message threads where third parties are included.

For people involved in surrogacy arrangements, independent legal representation is not just a formal requirement. It also helps ensure that each party receives advice that remains properly protected unless and until there is a clear reason to disclose it.

Why this matters in family and fertility law

Family and fertility law matters are often deeply personal. Clients are dealing with sensitive information, significant decisions, and relationships that may be delicate even when they are respectful.

That is exactly why confidentiality matters.

Whether the issue is a family court dispute or a surrogacy arrangement built on trust and shared intention, legal professional privilege helps create a safe space for proper advice. It allows clients to understand risks, consider options, and make informed decisions without exposing their confidential legal communications unnecessarily.

In Australia, surrogacy laws differ by state and territory, and official legal framework information can be accessed through relevant government resources, including the Australian Government Department of Health, Disability and Ageing for broader reproductive and health policy context.

A final word of caution

Legal professional privilege is not just a technical rule for lawyers to worry about. It is a client right, and it can be lost more easily than many people realise.

The danger is often greatest when people are trying to be helpful, transparent, or cooperative. In family law and surrogacy law matters especially, that instinct is understandable. But good intentions do not prevent waiver.

If a communication was created for the dominant purpose of legal advice or litigation, it may well be privileged. Before passing it on to anyone else, it is worth pausing and getting legal advice first.

That one step may protect not just a single document, but an entire body of confidential legal advice.
