How Are Post-Separation Contributions and Changes in Asset Value Treated?
Separation does not freeze the pool. What happens between separation and final resolution is considered under the current s 79 and s 90SM framework as part of contributions, current and future circumstances and the just-and-equitable requirement.
Key points
- Separation does not freeze the property pool. Under s 79 (married) and s 90SM (de facto) of the Family Law Act 1975 (Cth) as amended with effect from 10 June 2025, the Court identifies the parties' existing rights, interests and liabilities and considers contributions and current and future circumstances up to the date of decision.
- There is no universal valuation date. Assets and liabilities are ordinarily valued as at the date most useful for the actual decision, with account taken of what has occurred since separation; valuation method and date are fact-specific and often supported by expert evidence.
- Post-separation contributions (financial, non-financial, homemaker and parent, and — where the law and evidence support it — the economic effect of family violence) are considered on the same statutory basis as contributions during the relationship. There is no automatic dollar-for-dollar credit for mortgage or outgoing payments.
- Passive market movements are not automatically attributed to any party; active management, preservation, improvement or dissipation may be relevant contributions. Occupation of the home does not give rise to routine occupation rent.
- Post-separation income, savings, new assets, new debts, inheritances, gifts, trust distributions, superannuation accrual and cryptocurrency changes are considered on the facts under s 79 or s 90SM; there is no automatic exclusion or inclusion.
- Married applications must ordinarily be filed within 12 months of the divorce order taking effect (s 44(3); leave under s 44(4)); de facto applications within 2 years of the end of the relationship (s 44(5); leave under s 44(6)). Obtain advice before any irreversible step.

Post-separation events — mortgage and outgoings payments, market movements, business growth, savings and income, new assets and debts, occupation of the home, receipt of inheritances or gifts — are frequently in issue. Their treatment is not mechanical: it is considered under the current s 79 and s 90SM framework.
Current framework (s 79 / s 90SM)
Under the Family Law Act 1975 (Cth) as amended with effect from 10 June 2025, property adjustment is considered under s 79 (married) or s 90SM (de facto), which require the Court to identify the parties' existing rights, interests and liabilities, consider contributions of all kinds, consider current and future circumstances, and be satisfied that any order altering interests is just and equitable in all the circumstances. The former framing that applied to property has been superseded.
Identifying rights and valuation
Identification of existing rights, interests and liabilities is a precondition to a principled decision. Reliable valuation of the relevant asset or liability is required. There is no universal valuation date; typically assets are valued as at the date most useful for the actual decision, with account taken of what has occurred since separation. Valuation method and date are fact-specific and often supported by expert evidence.
Post-separation contributions
Contributions after separation are considered on the same statutory basis as contributions during the relationship. Relevant contributions can include:
- financial contributions — including mortgage principal or interest, outgoings, and payments preserving value;
- non-financial contributions — including active management, preservation and improvement;
- contributions to the welfare of the family — including as homemaker and parent;
- where the law and evidence support it, the economic effect of family violence.
Market movements and active management
Passive market movements after separation are not automatically attributed to either party. Where a party actively manages, preserves or improves an asset, those actions may be considered as contributions. Wastage or dissipation may also be relevant, subject to evidence and the applicable test. There is no presumption that an increase or decrease in value belongs to a particular party.
Mortgage, occupation, income and debts
Mortgage and outgoing payments, occupation of the family home, post-separation income and savings, and new debts are considered as follows:
- Mortgage and outgoings: considered on the facts; no automatic reimbursement or credit.
- Occupation: occupation rent is not routine; whether allowed or offset depends on the evidence.
- Income and savings: considered by reference to source, timing, use and whether they form part of the pool.
- New debts: considered by purpose, benefit and reasonableness in the circumstances.
- Superannuation accrued after separation: considered under Part VIIIB (or Part VIIIAB) as part of the assessment.
Inheritances, gifts, trusts and crypto
Inheritances, gifts, family advances, trust and company interests, cryptocurrency, bonuses and redundancy payments received after separation are considered on their facts. Valuation is often complex and may require expert evidence. Family violence is considered within the current law and the evidence.
Interim relief and preservation
Interim relief may address occupation, mortgage and outgoings, disclosure, preservation, injunctions and, where the statutory conditions are met, orders under s 106B. Interim relief is discretionary and depends on the evidence.
When to obtain advice
Advice should be obtained before any irreversible step is taken and before any applicable time limit approaches. See our related guide on mortgage and household expenses after separation.
Frequently Asked Questions
Does separation freeze the property pool?
No. Separation does not freeze the property pool. Under s 79 and s 90SM of the Family Law Act 1975 (Cth) the Court identifies the parties' existing rights, interests and liabilities as at a date that permits a principled decision on the material before it, and considers what has occurred since separation as part of contributions and current and future circumstances.
Is there a fixed valuation date?
No. There is no universal valuation date. Assets and liabilities are ordinarily valued as at the date most useful for the actual decision, typically the date of trial or agreement, but with account taken of what has occurred since separation. Valuation method and date are fact-specific and often supported by expert evidence.
If I paid the mortgage after separation, am I automatically credited?
No. Post-separation mortgage payments are considered as part of contributions and current and future circumstances. Whether, and to what extent, they are recognised depends on the source of funds, occupation, care of children, competing housing costs, preservation of value and the whole assessment; there is no automatic dollar-for-dollar credit.
If the market rose (or fell) after separation, who gets the benefit or bears the loss?
Passive market movements are not automatically attributed to either party. Active management, preservation, further investment or dissipation may be relevant contributions. How gains or losses are treated depends on causation, evidence and the just-and-equitable requirement.
How are post-separation savings, bonuses or income treated?
Post-separation income, savings, bonuses, redundancy payments and new assets are considered in context. Whether they form part of the pool or are recognised as a contribution or under current and future circumstances depends on source, timing, use and the whole assessment.
Are new debts after separation deducted from the pool?
Not automatically. Post-separation debts are considered by reference to purpose, benefit to the parties or their family, and whether they were reasonable in the circumstances. Deduction is not mechanical.
Is occupation of the family home 'occupation rent' post-separation?
Not automatically. Occupation rent is not a routine debt. Whether it is allowed, offset against mortgage or outgoings paid by the occupier, or dealt with as part of the broader assessment depends on the facts, including any exclusion, safety, children's arrangements and the parties' financial positions.
How are inheritances, gifts, trust distributions or crypto changes after separation treated?
Each is considered on its facts under s 79 or s 90SM. There is no automatic exclusion or inclusion. Timing, source, use, disclosure and evidence matter, and expert evidence may be required for valuation.
Can I get interim orders while final orders are pending?
Yes, subject to the applicable tests. Interim orders can address occupation, mortgage and outgoings, preservation of value, disclosure and access to funds; injunctions or orders under s 106B may be sought where the statutory conditions are met. Interim relief is discretionary and depends on the evidence.
What are the time limits?
Married parties must ordinarily apply within 12 months of the divorce order taking effect (s 44(3)); leave under s 44(4). De facto parties must ordinarily apply within 2 years of the end of the relationship (s 44(5)); leave under s 44(6).
