Superannuation and Divorce in Australia: How to Split Super After Separation

Superannuation is often the second-largest asset in a relationship after the family home — yet it's the one most people overlook during separation. Under the Family Law Act 1975, super is treated as property and can be split between separating spouses. But it works differently from dividing a bank account or selling a house.

Splitting super does not give you cash. It transfers a portion of one person's super balance into the other person's super account, where it remains locked until that person reaches their preservation age or meets another condition of release. Understanding how this process works — and the strict procedural requirements — is critical to getting it right.

How Super Splitting Works

A superannuation splitting order directs the trustee of one party's super fund to transfer a specified amount or percentage to the other party's super account. The receiving party must have (or open) their own super account to receive the transfer.

There are three ways to formalise a super split:

1. Consent orders — the most common method, where both parties agree on the split and file with the Federal Circuit and Family Court
2. Court orders — made by a judge after a contested hearing
3. Binding Financial Agreement (BFA) — a private contract between the parties, but both must receive independent legal advice

Regardless of which method you use, the super fund trustee is a mandatory participant in the process.

The 28-Day Trustee Notification Rule

This is where most self-represented litigants get caught out. Before you file superannuation splitting orders with the court, you must:

1. Send a draft copy of the proposed super splitting orders to the fund trustee
2. Give the trustee at least 28 days to review the orders and confirm they can be administered
3. Include the trustee's response with your court filing

If you skip this step or don't allow the full 28 days, the court will refuse to make the orders. The trustee also has the right to object if the orders are drafted in a way the fund cannot execute — for example, specifying a dollar amount that exceeds the member's balance.

Valuing Superannuation

The valuation method depends on the type of fund:

Accumulation Funds

Most Australians hold accumulation-style super (AustralianSuper, Hostplus, Sunsuper, REST, etc.). The value is simply the current account balance shown on the most recent member statement. Request an up-to-date statement from the trustee — online portals typically show the latest balance, but a formal statement may be required for court purposes.

Defined Benefit Funds

Defined benefit funds are common among public servants, defence personnel, teachers, and emergency services workers. They do not have a simple account balance. Instead, benefits are calculated using formulas based on years of service, final salary, and age-based multipliers.

The family law value of a defined benefit interest must be calculated using actuarial methods prescribed under the Family Law (Superannuation) Regulations 2025. The fund trustee will provide raw data via a Form 6 declaration and an information request, but they will not calculate the family law value. You need a consulting actuary or specialist financial planner to do that.

For the 2025-26 financial year, the interest rate applied to defined benefit base-amount adjustments is 6.9%, as published in the Commonwealth Gazette.

Self-Managed Super Funds (SMSFs)

SMSFs require the trust deed and three years of audited financial statements. Valuing SMSF assets can be complex if the fund holds real property, unlisted investments, or related-party loans.

Finding Hidden Super

If you suspect your former partner has super accounts they haven't disclosed, you don't have to take their word for it. Once family law proceedings are active in the FCFCOA, you can apply through the court for the Australian Taxation Office (ATO) to conduct a comprehensive search. The ATO will disclose all registered super interests held in that person's name, including lost super and SMSF balances.

Super Splitting vs Offsetting

You don't have to split super directly. An alternative is offsetting — where one party keeps their full super balance and the other receives a larger share of other assets (like more equity in the family home) to compensate. Offsetting avoids the administrative complexity of splitting orders and trustee notifications.

However, offsetting isn't always fair. Super and cash have different characteristics: super is locked until preservation age, while cash or property equity is available now. A dollar of super is not worth a dollar of cash if you are 35 and won't access it for 30 years. A good settlement accounts for this time-value difference.

Practical Steps

1. Request member statements from every super fund — both parties, all funds
2. Identify fund types — accumulation vs defined benefit matters for valuation
3. Send the ATO search request early if you suspect hidden accounts
4. Engage an actuary if either party has a defined benefit fund
5. Draft the splitting orders and serve them on the trustee with the 28-day notice
6. Include the trustee's response when filing consent orders
