When long-term marriages reach a breaking point, many older Australians hesitate to pursue formal divorce proceedings. For some, the emotional strain, financial implications, and religious or social considerations make divorce less appealing.
Under the Family Law Act 1975 (Cth), there is no legal obligation for separated spouses to divorce. Instead, couples can adopt legally recognised alternatives that maintain autonomy while managing financial and estate obligations responsibly.
This guide outlines the primary legal, financial, and procedural options available to older couples seeking alternatives to divorce in Australia.
Legal separation is the most common alternative to divorce for senior spouses. It allows couples to live apart and separate their finances without dissolving the marriage.
Under section 49 of the Family Law Act 1975 (Cth), separation occurs when one or both parties intend to end the relationship and communicate that intention. While divorce terminates marital status, separation simply ends the shared household or marital consortium.
Key legal implications include:
Legal separation is often chosen by older Australians who wish to protect financial arrangements, preserve pension entitlements, or maintain continuity in health and aged-care planning.
Even without divorce, separated spouses can finalise property and financial matters under the Family Law Act 1975 (Cth).
Sections 90B–90KA (for marriages) and 90UA–90UN (for de facto relationships) allow parties to enter Binding Financial Agreements (BFAs) that formalise asset division, superannuation splitting, and maintenance obligations.
Benefits of formal agreements include:
In the absence of a formal agreement, the Federal Circuit and Family Court of Australia retains jurisdiction to determine equitable division under section 79 of the Act, applying principles of justice and fairness.

Remaining legally married after separation has direct consequences under succession law. Unless a will specifies otherwise, a separated spouse may still inherit the deceased partner’s estate under intestacy provisions.
To prevent unintended outcomes, couples should:
Estate planning is particularly critical for older Australians. Without updated documents, the surviving spouse could claim the estate under family-provision legislation such as the Succession Act 2006 (NSW) or equivalent statutes in other jurisdictions.
A trial separation is a temporary legal arrangement that enables couples to live apart while assessing whether reconciliation or permanent separation is appropriate.
During a trial separation, parties may:
Although not required by law, formalising a trial separation through a Separation Agreement or Consent Orders can prevent misunderstandings, particularly where real property or shared accounts are involved.
Older Australians must carefully consider how separation affects retirement entitlements. Under the Social Security Act 1991 (Cth), marital status and financial independence determine eligibility for Age Pension and related benefits.
Couples who separate but remain legally married are usually assessed as individuals if they no longer live together or share finances.
Additionally:
Legal and financial advice is essential to avoid unintended tax or benefit consequences.

The Family Law Act 1975 (Cth) encourages reconciliation where possible. Sections 13A–13C require lawyers to inform clients about counselling and reconciliation services prior to filing for divorce. For older couples, professional counselling can provide clarity and structure in decision-making.
Common options include:
These processes are confidential and can coexist with legal consultation to ensure informed consent and compliance with procedural fairness.
Many senior couples prefer to maintain proximity for emotional or family reasons while living independently.
Under Australian family law, separation can occur even when spouses reside under the same roof - known as “separation under one roof.”
To establish this legally, evidence must show:
Affidavit evidence may be required if a divorce is later filed, so clear documentation is key. LegalFinda can connect you with professionals to find a family lawyer experienced in handling these unique living arrangements.
Although family law focuses on rights and obligations, emotional consequences cannot be ignored.
Long marriages often involve decades of shared identity and assets. Separation in later life can affect mental health, social networks, and family dynamics - especially when adult children or grandchildren are involved.
Family counsellors and psychologists trained in elder relationship issues can help couples navigate the transition while safeguarding emotional wellbeing.

Below are the most common legal and procedural questions older Australians ask when considering alternatives to divorce.
Legal separation, Binding Financial Agreements, trial separation, and formalised estate planning are all valid alternatives under Australian family law.
Yes. Couples may live separately without dissolving the marriage. However, they should formalise property and estate matters to avoid future disputes.
It can. Separated spouses may be individually assessed for Age Pension benefits, and superannuation can be split via court orders even without divorce.
If one spouse dies without a new will, the surviving spouse retains inheritance rights. Updating estate documents is essential to ensure intended distribution.
While not mandatory for separation, lawyers must advise clients about available counselling services before filing for divorce under sections 13A–13C of the Family Law Act 1975 (Cth).
For older Australians, the decision not to divorce is as much a legal strategy as a personal choice.
By leveraging instruments such as financial agreements, separation documentation, and updated estate plans, couples can achieve legal clarity without terminating their marriage.
