Defined Benefit Super Splitting in a Divorce: SASS, CSC & Tasmania Public Sector

Splitting a defined benefit super fund in a divorce is fundamentally different from splitting an accumulation fund. There's no simple account balance to halve — instead, the split reduces a future pension entitlement, requires an actuary, and takes months longer to process.

Why Defined Benefit Is More Complex

An accumulation fund works like a bank account: contributions plus investment returns equal a balance. You can split that balance by dollar amount or percentage, and the mechanics are straightforward.

A defined benefit fund promises a pension calculated from your salary, years of service, and a scheme-specific formula. The "value" of the benefit depends on projected future payments, life expectancy, discount rates, and the scheme's rules. There's no account balance to divide — an actuary must calculate the present value of those future entitlements under the Family Law (Superannuation) Regulations 2025.

Common Defined Benefit Schemes in Tasmania

Tasmania's public sector workforce commonly holds interests in:

State Authorities Superannuation Scheme (SASS) — Covers employees of Tasmanian state government agencies and authorities. The Retirement Benefits Fund administers SASS interests. The scheme has specific family law information kits that outline how valuations and splits are handled.

Commonwealth Superannuation Corporation (CSC) — Federal public servants, defence personnel, and military members often hold CSS, PSS, or PSSap interests. CSC has its own family law processing team and requires submissions through their dedicated portal.

Both schemes require fund-specific valuation information before the split can be processed. You cannot simply agree on a dollar amount and have it transferred.

The Valuation Process

Submit a Form 6 Declaration and Information Request to the fund trustee. For defined benefit schemes, the response includes either:

• A valuation calculated by the scheme's actuary based on the Regulations
• A direction to engage an independent actuary, along with the data they need

The valuation determines the "eligible superannuation interest" — the portion of the benefit that's available for splitting under family law. Not all components of a defined benefit may be splittable (preserved vs unrestricted components, for example).

For SASS, the Retirement Benefits Fund provides a family law valuation on request. Ask the fund for its current processing time when you submit the request.

How the Split Works

Unlike an accumulation fund where the trustee simply transfers a dollar amount, a defined benefit split typically:

1. Reduces the member's future pension entitlement by the agreed amount or percentage
2. Creates a "splittable payment" — either a lump sum rolled into the receiving spouse's chosen accumulation fund, or in some schemes, a separate defined benefit interest

The method depends on the scheme's rules. CSC schemes, for example, may offer both a lump sum and a new defined benefit interest option, each with different financial implications.

The 28-Day Procedural Fairness Notice

The same 28-day notice requirement that applies to accumulation fund splits applies here — but defined benefit trustees are more likely to raise objections during this period. Common issues include:

• Proposed orders that are inconsistent with the scheme's splitting rules
• Orders that reference an incorrect valuation date
• Orders that attempt to split a component the scheme considers non-splittable

Serve the draft consent orders on the trustee and give them the full 28 days. If the trustee raises issues, you'll need to amend the orders and re-serve, which can add another 28-day review period.

Timeline Expectations

Accumulation fund splits can be processed in weeks. Defined benefit splits generally take longer than accumulation splits. Ask the trustee for its current processing timeline and budget extra time when planning your property settlement.
