The mother is always certain. The father, not so much. The others- donor, surrogate, partner who consented, partner who didn't, intended parent, parent who turned up later- gets harder to navigate every year the technology moves and the legislation doesn't.
At our most recent CPD session, Stephen Page from Page Provan walked members and guests through where the law currently sits on the question of who is a legal parent. In sixty years of assisted reproductive technology, there are three competing systems (federal, state, and Western Australia), and a string of 2025 cases pulling in different directions.
The recording is below.
Ophoven & Berzina Decision & Law Reform
The Ophoven & Berzina appellate decision came down in May 2025. It confirmed that a man can be a legal parent with no biological connection to the child, no gestational connection, and without having consented to the conception. What matters is their conduct after.
The second reason is the Australian Law Reform Commission's surrogacy review, with the final report due to the Attorney-General by 29 July 2026. The law on parentage is about to evolve, and Stephen has spent more than three decades watching it move.
What the session covered
Stephen took the room from first principles (the Roman law presumption that the mother is always certain) through to where parentage law actually lands in 2026. The thread connecting it all: parenthood today is a question of fact, and the facts include biology, intention, conduct, and the state you happen to be in.
A few of the points that landed hardest:
- The history of ART in Australia. Australia produced the world's third IVF baby in 1980 and pioneered single embryo transfers in the 1990s. The legal framework has been chasing the technology ever since.
- The Ophoven facts. Seven actions over five years that turned a man with no biological tie into the child's legal father.
- The Lloyd & Compton 2025 case, where Queensland intended parents who used overseas commercial surrogacy ended up referred to the Director of Public Prosecutions and their lawyer referred to the NSW Legal Services Commissioner. A cautionary tale.
- The "more than two parents" question. The Family Law Act technically allows for it. No-one has tested it yet.
- The state quirks. WA runs a separate system. Victoria's birth register doesn't auto-update with interstate surrogacy orders. Queensland's "no rights or liabilities" donor framing is doing less work than it used to.
