Frozen Embryos in Australia: StorageLimits, Separation and Consent

Most IVF cycles create more embryos than can be transferred at once. The spare embryos are frozen and stored, sometimes for years. That’s good news for families who want a sibling later, but it raises questions that many people don’t think about when they sign the clinic paperwork.

How long can frozen embryos be stored? Who decides what happens to them if a couple separates, or if one person dies? And what do your consent forms already say? This guide covers the legal side of frozen embryos in Australia.

How are embryos frozen and stored?

After egg collection and fertilisation, embryos are grown in the lab for a few days. Any good-quality embryos that aren’t transferred straight away are frozen using a fast-freezing method called vitrification and stored in liquid nitrogen. Most frozen embryos survive thawing, and a frozen embryo transfer is now a routine part of IVF. Freezing eggs on their own is different, and our post on egg preservation covers the legal side of egg freezing.

While the embryos are in storage, the clinic holds them under the consent forms you signed. You pay storage fees, and the clinic will contact you when a storage period is about to end. Our page on embryo freezing and gamete transfers covers moving embryos between clinics.

How long can frozen embryos be stored in Australia?

Storage limits depend on your state and on your clinic’s consent forms. Some states set limits in law. Others leave it to national ethical guidelines and clinic policy.

• Victoria: embryos can be stored for an initial period of 5 years, then for up to another 5 years if an extension is approved. Longer storage needs further approval.
• Western Australia: storage is limited by law, with extensions available in some circumstances.
• New South Wales, Queensland and the other states: clinics follow national guidelines and their own storage periods, and Queensland’s Assisted Reproductive Technology Act 2024 adds new rules as it commences.

Whatever your state, your consent forms set the storage period that applies to your embryos. If you want to keep them longer, act before that period ends. If a clinic can’t reach you, it may be able to discard embryos once the period is over.

What do IVF consent forms say about frozen embryos?

Before treatment, each person who provides eggs or sperm signs consent forms. For embryos, these usually cover:

• Use: who can use the embryos, and whether they can be used only by the couple together
• Storage: how long they’ll be stored and what happens when the period ends
• Separation: what happens if the couple separates or divorces
• Death or incapacity: whether a surviving partner can use the embryos
• Disposal and donation: whether unused embryos can be discarded, donated to research or donated to another family

Many people sign these forms quickly, early in treatment. They matter far more than most people realise. Read them carefully, ask questions, and update them if your circumstances change.

What happens to frozen embryos if a couple separates?

This is where most disputes start. Under national guidelines, clinics generally need both people whose eggs and sperm created the embryos to agree before embryos are used, donated or discarded. Either person can usually withdraw consent before an embryo is transferred.

In practice, that means:

• One person can’t use the embryos alone after separation, unless the other consents
• The embryos stay in storage while the storage period and fees allow, or until you both agree what to do
• Courts can be asked to decide in some cases, but outcomes are uncertain and embryos aren’t treated like ordinary property

If you used donor sperm or donor eggs, the position can be different, because only one partner is a genetic parent. That’s common with reciprocal IVF and donor egg treatment. Get advice on your own consent forms. Our page on parentage disputes explains how these cases are handled.

Can I use our frozen embryos after my partner dies?

Sometimes. It depends on what your partner consented to, your state’s law and the clinic’s policy. Some states allow use after death only if the person gave written consent to posthumous use. Others require approval from a regulator or a court. Our page on posthumous conception covers the rules.

Your will can also help. It can’t override consent forms, but it can record what you want to happen to stored embryos.

What are the options for frozen embryos you no longer need?

When your family is complete, you’ll usually have four choices:

• Keep them in storage for now, within the storage limit
• Donate them to another person or couple so they can have a baby.
• Donate them to research, where a licensed research project is available
• Allow them to be discarded at the end of storage

Each option needs the consent of both gamete providers. Counselling is available through clinics and can help with what’s often an emotional decision.

How to protect your frozen embryos

• Read and keep copies of every consent form you sign
• Update your consents if you separate, re-partner or change your plans
• Keep your contact details current with the clinic, so storage reminders reach you
• Make or update your will, and name who can make decisions if you can’t
• Get legal advice before a separation, if you’re moving embryos interstate, or if you’re considering donation

How we can help

We advise individuals and couples on frozen embryos, consent forms, separation disputes, posthumous use and embryo donation. If you’re separating and have embryos in storage, get advice early, before either of you takes a step that’s hard to undo.
