You’ve either just started receiving spousal maintenance, or you’ve just been ordered to pay it, and the same question is sitting there unanswered: how long does alimony last and actually go on for?
It’s a genuinely important question to get right. Assume it’s permanent when it isn’t, and you might structure your finances around support that’s going to stop sooner than expected. Assume it’ll end quickly when the circumstances actually support a longer arrangement, and you might walk away from support you were entitled to, or underestimate an obligation you’re going to be paying for years.
This guide explains how long alimony, known legally in Australia as spousal maintenance, actually lasts, what determines the duration, and what can cause it to end earlier or later than expected.

Alimony vs Spousal Maintenance: A Quick Clarification
Australian law doesn’t use the term alimony, that’s the term used in the US, it’s referred to as spousal maintenance here, sometimes called spouse maintenance. Alimony in Australia works differently to how it’s understood overseas, and understanding that difference matters before you can even answer the “how long” question properly.
It means financial support one spouse or de facto partner may be required to provide to another after separation or divorce, where one party genuinely can’t support themselves and the other has the capacity to pay.
Spousal maintenance is financial support intended to bridge a genuine gap, not to punish the paying party or reward the recipient. Our guide on spousal maintenance in Australian family law covers the basics if you’re new to the topic.
Who Can Apply for Spousal Maintenance, and What Are the Time Limits?
Before duration becomes relevant, eligibility has to be established first. Both married and de facto partners can apply for spousal maintenance, provided they meet the legal criteria, and time limits apply strictly to the application for spousal maintenance itself: generally 12 months from a divorce becoming final for married couples, and two years from separation for de facto couples. Missing these time limits generally means needing the court’s special permission to apply late.
Whether spousal maintenance is payable comes down to a two-part test the court considers whether the applicant is unable to adequately support themselves, and whether the respondent’s capacity to pay exists once their own reasonable needs are met.
In relation to spousal maintenance, both conditions generally need to be satisfied, an applicant who cannot meet their own reasonable expenses still won’t succeed if the other party genuinely can’t provide financial support either.
There’s No Fixed Duration for Spousal Maintenance
Unlike child support, which generally continues until a child turns 18, there’s no set duration written into the Family Law Act 1975 for spousal maintenance. Spousal maintenance is not automatic in the first place, and once it is ordered, how long it lasts depends entirely on individual circumstances, not a fixed rule or standard timeframe. Maintenance may run for a matter of months or considerably longer, and maintenance is usually reviewed against the same underlying question throughout: does the applicant still need support, and does the other party still have the capacity to pay it.
This is one of the most common points of confusion. People often assume alimony works the same way it does in some other countries, running for years or even a lifetime by default. In Australia, that’s rarely the case. Spousal maintenance is generally intended as temporary financial support, not a permanent income, and the court’s aim is to help someone become self-sufficient, not to equalise two people’s incomes indefinitely.
This reflects a broader principle in Australian family law, that spouses have an equal duty to support and maintain each other where genuine need and capacity to pay both exist, not an open-ended entitlement.
Urgent, Interim, and Final Maintenance
How long alimony lasts also depends on what type of order is in place, and the court may make different orders depending on how urgent the situation is:
- Urgent spousal maintenance: short-term support ordered quickly, when someone is in immediate financial need and can’t wait for the full process to play out. This bridges the gap until a more considered order can be made.
- Interim maintenance: support ordered while a matter is still being finalised, before a final decision is reached, often covering the period during property settlement negotiations, and an order is made on the basis of the information available at that point.
- Final maintenance: the longer-term arrangement, decided either by agreement between the parties or by court order after considering the full financial picture. This can be a lump sum, or spousal maintenance payments made periodically for a defined or indefinite period, and either party can apply to vary a final order if circumstances genuinely change later.
Factors That Determine How Long Spousal Maintenance Lasts
When deciding how long an order should run, the court considers many of the same factors used to decide whether spousal maintenance is payable in the first place, weighing property and financial resources alongside personal circumstances, including:
- The length of the marriage or de facto relationship. Longer relationships more often support longer maintenance arrangements, particularly where one partner’s earning capacity was significantly affected by the relationship, such as time out of the workforce raising children.
- Age and health of the receiving party. Older applicants, or those with health conditions limiting their ability to work, may receive maintenance for longer than someone expected to become self-sufficient relatively quickly.
- Earning capacity and financial resources. If the receiving party has skills, qualifications, or resources that could realistically support them again soon, maintenance is often shorter, sometimes tied to a specific retraining or job-search period, since support depends heavily on how quickly someone can reasonably become self-supporting.
- Caring for children of the relationship. A parent with primary care of a child of the relationship may need longer support, since their capacity to work full-time is genuinely reduced, particularly while children are young.
- Standard of living during the relationship, weighed against what’s realistic and equitable going forward, rather than an exact replication of pre-separation life, and the court will consider whether the applicant can reasonably be expected to support yourself adequately within a shorter timeframe or not.
When Does Spousal Maintenance End?
A few specific events commonly bring spousal maintenance to an end:
- The recipient remarries. Spousal maintenance ends automatically when the receiving party remarries, unless there are exceptional circumstances that justify the court making an order for it to continue.
- A new de facto relationship begins. Unlike remarriage, this doesn’t end maintenance automatically, but the court can take the new partner’s financial circumstances into account when deciding whether to reduce or end the arrangement.
- The fixed term expires. If the order specified a set period, maintenance simply ends once that period is up, unless either party successfully applies to vary it beforehand.
- The recipient becomes able to support themselves. If financial circumstances change enough that the original threshold test is no longer met, either party can apply to the court to end or vary the order.
- The payer’s capacity to pay changes. A significant change, such as job loss, illness, or retirement, can also be grounds to apply to reduce or end maintenance, even before an agreed end date.
Can Spousal Maintenance Be Varied or Reviewed?
Yes. Spousal maintenance arrangements aren’t necessarily locked in once made. Either party can apply to the court to vary, suspend, or terminate an existing order if there’s been a genuine and significant change in financial circumstances, on either side, since the order was made. This isn’t automatic or guaranteed, the court will look at whether the change is real and substantial, not simply inconvenient. Our guide on how spousal maintenance interacts with other financial issues after separation covers some of the financial disclosure obligations relevant to this process.
Married Couples vs De Facto Couples: Does Duration Differ?
The underlying principles are the same for both, but there are some practical differences worth understanding. Time limits to apply differ, married couples generally need to apply within 12 months of a divorce becoming final, while de facto couples generally have two years from the date of separation. Once an order is made, though, the same factors, length of relationship, age, health, earning capacity, and care of children, determine how long the maintenance itself will run, regardless of whether the relationship was a marriage or a de facto relationship. This applies whether your matter is heard through the Federal Circuit and Family Court of Australia or the Family Court of Western Australia.
Planning for a Spousal Maintenance Arrangement That Will End
Because most spousal maintenance is genuinely temporary, it’s worth planning your finances around that reality from the start, rather than treating it as permanent income. Our guide on budgeting after separation is a useful practical resource if you’re working out how spousal maintenance, along with other income sources, fits into your overall financial position going forward.
When to Seek Legal Advice
Because how long spousal maintenance lasts depends so heavily on individual circumstances, it’s worth getting advice from an experienced family lawyer early, whether you’re applying for maintenance, responding to a claim, or trying to understand how a change in your circumstances might affect an existing order. Formalising an arrangement through consent orders or a binding financial agreement can also provide more certainty than an informal understanding about when, and how, the arrangement will end.

Frequently Asked Questions
How long do I have to pay spousal support in Australia?
There’s no fixed period, it depends on the circumstances of your case. Some arrangements last only a few months, intended to help someone get back on their feet, while others continue for years in cases involving long relationships, health conditions, or ongoing care of young children. Either party can apply to vary or end the arrangement if circumstances change significantly.
What is the highest alimony payment?
There’s no fixed maximum or cap under Australian law. The amount is based on the receiving party’s genuine need and the paying party’s capacity to pay, assessed individually in each case, so higher payments generally reflect higher income and financial resources on the paying party’s side, not a standard or capped figure.
Does the wife get half in a divorce in Australia?
No, there’s no automatic 50/50 split, and the law applies equally regardless of which partner is applying. Property settlement is based on financial and non-financial contributions during the relationship, along with future needs, so the outcome can be even or meaningfully uneven depending on the circumstances, separate from any spousal maintenance arrangement.
How much child support will I pay if I make $100k in Australia?
There’s no single answer, since child support is calculated using a formula that also factors in the other parent’s income, how many children you have, their ages, and the care arrangement, not your income alone. The Child Support Agency’s online estimator is the most reliable way to get a figure specific to your situation, since two people earning $100k could have very different assessments depending on these other factors.
