Who is a Parent? (Australian Law Explained)

The question sounds simple. Who is a parent?

In law, it is anything but simple.

Biology matters. Birth matters. Intention matters. Paperwork matters. State law matters. Federal law matters. Sometimes they line up neatly. Sometimes they collide in ways that leave families, lawyers and government departments wrestling with very uncomfortable uncertainty.

That is especially true in a world of IVF, donor conception, surrogacy, same-sex parenting, overseas arrangements and modern family structures that do not fit the assumptions of older legislation.

This seminar, presented in collaboration with Clarence Professional Group, tackled that question head on: when does Australian law recognise someone as a parent, and when does it refuse to do so?

The old legal starting point: birth made motherhood certain

For centuries, the legal system worked from a very old idea: the woman who gives birth is known with certainty, while fatherhood is the thing that must be proved. That ancient starting point shaped parentage law for generations.

Then assisted reproduction changed everything.

Once IVF, egg donation, sperm donation and surrogacy entered the picture, the person who gave birth was no longer always the person understood by everyone involved to be the mother in the social or intended sense. The law’s old assumptions started to creak badly.

Modern parentage law is still, in many ways, trying to catch up.

Why assisted reproductive technology changed the debate

Australia has been a world leader in assisted reproductive technology. IVF developed rapidly here, and techniques such as donor egg treatment, frozen embryo transfer and ICSI transformed what family creation could look like.

ICSI in particular changed the landscape by allowing a single sperm to be injected directly into an egg. Combined with Australia and New Zealand’s strong emphasis on single embryo transfer to reduce risk, the practical realities of fertility treatment today look very different from the early IVF era.

At the same time, DNA testing became highly reliable. That had a huge impact on legal arguments about parentage. Courts no longer had to rely only on presumption and social appearance. Scientific proof could now answer biological questions with far greater confidence.

But biology alone did not settle everything. In many disputes, it simply opened the next question: does biological connection equal legal parenthood?

Status of Children laws: the usual rule for donation

Across Australia, each state and territory has legislation dealing with parentage and children born through assisted conception. The names differ slightly, but the structure is broadly familiar. Where a couple undergoes treatment with the proper consent, the couple is generally recognised as the child’s parents, and the donor is not.

That sounds straightforward, until it is not.

Some laws use old language. Some provisions sit awkwardly beside surrogacy legislation. Some states updated their frameworks more clearly than others. Western Australia, for example, has long had its own distinctive structure, and legislative reform there continues to evolve.

The key point is this: state law often answers parentage questions for births and surrogacy arrangements within that state. But anyone dealing with family law cannot stop there, because federal law may approach the same family in a different way.

The split system problem: state law and federal law do not always match

One of the hardest features of Australian parentage law is that there is no single, perfectly consistent definition of “parent” across every legal context.

That means a person may be treated as a parent for one purpose, but face resistance for another.

Examples include:

• State surrogacy proceedings, where state legislation determines who should be named and how parentage orders are made.
• Family Law Act matters, where the federal court may look at parentage through a different lens.
• Citizenship cases, where the question may become one of fact rather than simple biology.
• Migration matters, where recognition of a family relationship does not automatically mean a child can enter Australia without difficulty.

This is why apparently small mistakes can create major trouble. A classic example is putting the intended parent on the birth registration too early in a surrogacy matter when state law does not yet permit it. That can derail later court processes and generate exactly the kind of avoidable pain nobody needs.

Section 60H and why consent matters so much

Within the Family Law Act 1975, section 60H is one of the most important provisions dealing with children born through artificial conception procedures.

At a broad level, it deals with:

• couples who undergo treatment
• single women who undergo treatment
• a provision concerning men alone, which has not really come to life in practice because no prescribed laws activate it

The central issue is often consent.

If a couple undertook assisted conception and the relevant consent existed, the law may recognise them as parents and exclude the donor. But consent is not always as neat as a clinic form signed in blue pen on a particular day. It may be oral. It may be inferred from conduct. It may become the heart of a factual dispute years later.

That is especially important in lesbian parenting cases, where one woman may have attended treatment and the other may not have physically gone to the clinic. The absence of a clinic signature does not necessarily mean the absence of consent. Equally, silence is not automatically consent either.

Once that issue is contested, the facts before and after conception become critical.

Surrogacy in Australia: parentage orders matter

For domestic surrogacy, state and territory laws provide the pathway for intended parents to become recognised as parents through a parentage order. Those orders are vital, and in principle they should be respected across Australia.

In practice, there have still been absurd complications. A parentage order made in one state may be perfectly valid, yet administrative issues can arise when trying to alter a birth register in another state. Victoria has been a notable example, requiring extra procedural steps in some cases where the child was born there but the order came from elsewhere.

That kind of duplication makes little policy sense. It adds cost, stress and delay to families who have already been through the legal process once.

Anyone considering local arrangements should understand the legal framework carefully before anything begins. Page Provan’s fertility law team advises on these issues across Australia and internationally.

International surrogacy: recognition has improved, but danger remains

International surrogacy has long produced some of the most difficult parentage disputes in Australia.

For years, outcomes in the Family Court were inconsistent. Similar facts could produce very different answers depending on the judge, the evidence and the legal route taken.

There has been real improvement. Changes to the Family Law Regulations now mean that for certain overseas jurisdictions, birth registration can create a presumption of parentage under federal law. If the overseas birth certificate names the intended parents, and the jurisdiction is prescribed, that can significantly simplify recognition.

That does not mean overseas surrogacy is easy.

Far from it. Citizenship, parentage, criminal law risk in some states, migration and document recognition all still require careful planning. A family can be lawfully recognised in one legal sense and still run into serious trouble in another.

For broader background on preparing for those risks, the Australian Government’s Smartraveller advice and the Department of Home Affairs citizenship and migration information are essential reference points.

Masson v Parsons: intention became impossible to ignore

If one case changed the modern Australian conversation about parentage, it is Masson v Parsons.

The High Court accepted that parentage under the Family Law Act can be a question of fact, and that biology is not always the whole story. Intention, conduct and the role actually played in the child’s life can matter profoundly.

That case involved a known sperm donor who was not merely a donor in the clinical, detached sense. He provided sperm with the understanding that he would be a father, was named on the birth certificate, and acted in that role. On those facts, the court found he was a parent.

This was a major point. It showed that a sperm donor is not always safely outside parenthood simply because donor conception occurred. Much depends on what was intended and how people behaved.

So when is a sperm donor a parent?

The uncomfortable but honest answer is: sometimes.

A donor may not be a parent where the arrangement clearly shows donation only, with no intention to parent and no later assumption of that role.

But a donor may be treated as a parent where facts point the other way, such as:

• an express understanding that he would be a father
• his name appearing on the birth certificate
• shared parenting conduct after birth
• the child knowing and relating to him as a parent

Written agreements are not magic, but they are extremely important. They help show intention at the beginning, before relationships sour and memories improve themselves.

That becomes even more pressing in informal arrangements and at-home insemination. The less structure there is, the more scope there is for later dispute.

Can there be more than two parents?

Australian law still tends to operate around a two-parent model, especially administratively. But modern case law leaves open the possibility that reality is more complicated.

Polyamorous families, blended donor-parent arrangements and other non-traditional structures challenge the neat old categories. Courts have shown increasing willingness to focus on the social and psychological role of a person in a child’s life, not just genetics.

That does not mean the law has fully embraced multi-parent recognition. It has not. But the direction of travel is clear enough: family life is changing faster than legislation.

Adoption, citizenship and migration can still trip families up

Another trap is assuming that recognition for one legal purpose solves everything else.

It does not.

An overseas adoption may be recognised under family law, yet still create migration complications. A surrogacy arrangement may produce a valid foreign order, yet still prompt a citizenship dispute. A family may feel perfectly secure until a government department applies a narrower or simply different test.

That is why early advice matters so much. Fixing a problem before a journey begins is usually far easier than rescuing one after the child is born overseas.

The practical lesson

The law of parentage in Australia is not a single tidy rule. It is a patchwork of history, statute, court decisions, administrative practice and social change.

Some broad themes do emerge:

• Biology matters, but it is not always decisive.
• Birth still carries enormous legal significance.
• Intention can be critical, especially in donor and non-traditional family cases.
• State and federal systems do not always align.
• Surrogacy, citizenship and migration issues should never be approached casually.

Parentage disputes are rarely just technical. They go to identity, family formation and a child’s place in the world. That is why this area of law matters so deeply, and why getting it right matters even more.
