When applying for an Australian partner visa, the married vs de facto partner visa question matters more than you might think. The visa subclasses are the same, but the eligibility rules, timing, and evidence requirements differ in important ways. Here’s how to know which applies to you.
Married vs De Facto Partner Visa: Ultimate Secrets to Success
Key takeaways
- The married vs de facto partner visa distinction is about how you qualify, not which visa you apply for. Both routes use the same subclasses (820/801, 309/100).
- Married couples: A valid marriage certificate skips the 12-month rule. However, you still need evidence the marriage is genuine.
- De facto couples: You must show 12 months of relationship before lodgement, unless an exception applies.
- Two key exceptions to the 12-month rule: relationship registration with an Australian state, or having a child together.
- Same-sex couples are fully recognised under both pathways.
- Evidence requirements (the four pillars: financial, household, social, commitment) apply to both — being married doesn’t reduce evidence needs.

1. The core difference: how you qualify
Applying for an Australian partner visa involves a critical decision: should you apply as a married couple or a de facto couple? While the visa subclasses are identical, the legal requirements for each vary significantly. This guide breaks down the married vs de facto partner visa distinction to help you determine which path fits your relationship and how to prepare the strongest evidence for a successful application in 2026.
Furthermore, Australian migration law recognises two ways to qualify for a partner visa: as a spouse (legally married) or as a de facto partner. The visa itself is the same — subclass 820/801 onshore or 309/100 offshore — but the path to qualifying differs. If you’re legally married, your marriage certificate establishes the relationship in the eyes of the Department of Home Affairs. However, if you’re not married, you must instead prove a genuine de facto relationship that has existed for at least 12 months before you lodge.
Consequently, the married vs de facto partner visa distinction isn’t a “which visa do I apply for” question. Rather, it’s a “which evidentiary path applies to me” question.
Important: Whether married or de facto, you still need to prove the relationship is genuine and continuing. Marriage doesn’t exempt you from providing evidence across the four pillars (financial, household, social, commitment). It just removes the 12-month relationship duration requirement.
2. The married route — what counts as marriage
What Australia recognises as marriage
For partner visa purposes, your marriage must be valid under Australian law. This generally means the marriage was legally registered in the country where it took place. Moreover, both parties must have been free to marry with no existing marriages or prohibited family relationships. Both parties were at least 18 years old (or 16-17 with court approval). Finally, the marriage was conducted by an authorised celebrant or official.
As a result, same-sex marriages have been fully recognised in Australia since 2017. Meanwhile, marriages performed overseas in countries that also recognise same-sex marriage are usually valid here too.
Marriages that don’t count
- Religious-only ceremonies without legal registration in the country of marriage
- Polygamous marriages — Australia only recognises one marriage at a time
- Marriages where one party was already legally married elsewhere
- Forced marriages or marriages of convenience
The advantage of being married
The single biggest practical advantage: no 12-month minimum relationship rule. So you could theoretically marry your partner today and lodge a partner visa application tomorrow. However, lodging that quickly creates a different problem — limited evidence. Home Affairs will scrutinise your application carefully if the marriage is recent and your supporting evidence is thin. As a result, even married couples typically need to demonstrate substantial relationship history through other means.
3. The de facto route — and the 12-month rule
What counts as a de facto relationship
A de facto relationship for partner visa purposes is defined under Section 5CB of the Migration Act 1958. It requires a mutual commitment to a shared life to the exclusion of others. Additionally, the relationship must be genuine and continuing. You and your partner must not be related by family. Usually, you must live together, or don’t live separately on a permanent basis.
Furthermore, a de facto relationship is more than just dating. In fact, it’s a partnership that mirrors marriage in commitment level — without the legal marriage certificate.
The strict 12-month rule
If you’re applying as a de facto partner, your relationship must have existed for at least 12 months immediately before you lodge. This is a hard rule — there’s no flexibility. Lodging at the 11-month mark hoping to reach 12 months during processing leads to refusal. Consequently, the 12 months refers to the substantive de facto period, not casual dating. So if you dated for 6 months before moving in together and then lived together for 9 months, that’s not 15 months of de facto — it’s 9 months. As a result, you’d need to wait another 3 months before lodging.
Common error: Couples often confuse “knowing each other for 12 months” with “being de facto for 12 months.” The Department wants 12 months of committed shared life. So lodging too early is one of the most common reasons de facto applications get refused.
4. Exceptions to the 12-month de facto rule
Australian migration law builds in three important exceptions. Meeting any one of these waives the 12-month requirement.
Exception 1: Relationship registration
This is the most powerful exception and the easiest to use. If you register your relationship with an Australian state or territory authority, the 12-month requirement is legally waived. Relationship registration is currently available in New South Wales (NSW), Victoria (VIC), and Queensland (QLD). Furthermore, it is available in South Australia (SA), Tasmania (TAS), and the Australian Capital Territory (ACT).
Western Australia does not currently offer relationship registration for migration purposes. So if you’re in WA and need to skip the 12-month rule, marriage or relocating to register interstate are your options. Registration typically takes about 28 days from application. Importantly, this is far faster than waiting another 12 months.
Exception 2: Children of the relationship
Having a biological or legally adopted child together waives the 12-month requirement entirely. So if you have a child with your partner — or are expecting one — you can lodge straight away regardless of how long you’ve been together.
Exception 3: Compelling circumstances
In rare cases, the Department may waive the 12-month rule for compelling reasons. Examples include legal or safety barriers preventing you from living together in your home country. This might include LGBTQ+ persecution or serious illness affecting one party. However, this exception is harder to rely on. Outcomes vary case by case and the Department applies it strictly. So most applicants relying on compelling circumstances should seek migration agent advice first.
5. Evidence: married vs de facto requirements
One common myth: married couples need less evidence than de facto couples. In fact, the evidence requirements are nearly identical. Both routes need to satisfy the four pillars.
The four pillars (apply to both)
| Pillar | What it means | Examples |
|---|---|---|
| Financial | Shared finances and economic interdependence | Joint accounts, joint loans, shared bills, super beneficiary |
| Household | Shared domestic life and living arrangement | Joint lease/mortgage, utility bills in both names, mail to same address |
| Social | How others perceive you as a couple | Photos at events, wedding invites, Form 888 statutory declarations |
| Commitment | Long-term plans and emotional bond | Wills, life insurance beneficiaries, future plans, communication history |
What’s different for married couples
Married couples need only one extra document beyond the four pillars: a valid marriage certificate. However, having a certificate doesn’t reduce what’s needed in the other four areas.
What’s different for de facto couples
De facto couples need to additionally prove the 12-month duration of the relationship (or the exception that applies). So expect to provide lease agreements showing shared address for the period. Furthermore, include bills, mail, and government correspondence. Provide bank statements showing parallel financial activity. Additionally, provide photos covering the relevant period. If using exceptions, include the registration certificate or child’s birth certificate.

Take the Quiz →6. Which route gives a stronger application?
This is the question most couples ask: should we get married before applying to make the case stronger? The honest answer: it depends. In practice, an established de facto relationship with strong four-pillar evidence is just as strong as a recent marriage with weaker evidence. So the route doesn’t matter as much as the substance.
When marriage strengthens your case
- You’re under the 12-month de facto threshold and can’t register your relationship (e.g. living in WA)
- You want to skip waiting another year to qualify
- Cultural or family expectations make marriage more authentic for your relationship
- You’re applying for the subclass 300 prospective marriage visa
When de facto is just as strong
- You’ve been living together for 1+ year with consistent evidence across all four pillars
- You have joint financials, shared lease, and clear commitment evidence
- You can rely on relationship registration to skip the 12-month rule
- You’re philosophically opposed to marriage but committed to the relationship
Don’t marry just to strengthen the visa. A marriage entered into solely for migration purposes is grounds for refusal under Public Interest Criterion 4020. The Department looks at intent. So if marriage is right for you as a couple, it strengthens the application. If it’s purely strategic, it can backfire.
7. What if your status changes during the wait?
Partner visa processing takes 12–24 months. So it’s common for couples to experience life changes during the wait — and some of these affect your application.
If you marry during processing
You don’t need to switch streams. Instead, simply notify Home Affairs through ImmiAccount and upload your marriage certificate. The Department updates your file. So your existing application continues — only stronger.
If you have a child during processing
Notify Home Affairs and upload the birth certificate. A child of the relationship is some of the strongest evidence possible. Consequently, your case becomes meaningfully stronger.
If you separate during processing
This is more complicated. Generally, if you separate before the temporary visa is granted, the application typically can’t continue. However, if separation happens after the temporary visa is granted but before the permanent stage, limited pathways may still apply. For more detail on this, see our complete partner visa guide — section 9 covers relationship breakdown.
8. Common mistakes to avoid
Lodging too early as de facto
The most common mistake. Couples count their entire relationship history (including dating) instead of the de facto period. So they lodge before they’re eligible and face refusal. Always count from when you actually started living a committed shared life.
Assuming marriage means you skip evidence
A common myth. Marriage proves you went through a ceremony — not that the relationship is genuine. So you still need to demonstrate the four pillars with the same depth as a de facto applicant.
Trying to register your relationship in WA
Western Australia doesn’t currently offer relationship registration for migration purposes. So couples in WA who want to skip the 12-month rule need to either marry, register interstate (with proof of residence in that state), or wait.
Missing exemption opportunities
Many couples don’t realise they qualify for an exception. As a result, they wait an extra 6 months unnecessarily. If you have a child, are expecting one, or could register your relationship — those exceptions apply immediately.
Inconsistencies between partners’ statements
Both partners write personal statements describing the relationship. However, if dates, locations, or facts contradict each other, the Department flags the file. So coordinate the basics — first meeting date, when you moved in, key events — before submitting.
9. Frequently asked questions
Is the visa subclass different for married vs de facto?
No. Both routes use the same subclasses — 820/801 onshore or 309/100 offshore. The difference is in how you qualify, not which visa you receive.
Can we just register our relationship to skip the 12-month rule?
Yes, in most Australian states. Registration in NSW, VIC, QLD, SA, TAS or ACT waives the 12-month rule. However, you still need genuine relationship evidence — registration alone isn’t enough.
Does our marriage need to be recognised in Australia?
Yes. The marriage must be valid under Australian law. Most marriages legally registered overseas are recognised. However, polygamous marriages, religious-only ceremonies without legal registration, and marriages where one party was already legally married elsewhere are not.
Are same-sex couples treated the same way?
Yes. Australia recognises same-sex marriage and same-sex de facto relationships equally for partner visa purposes. The same eligibility rules and evidence requirements apply.
Can our online relationship count toward the 12 months?
Generally no. Time spent purely dating online without actually living together usually doesn’t count. The 12 months refers to a substantive de facto partnership, which typically requires shared physical life. Some exceptions exist for unique cases — speak to a migration agent if your situation is unusual.
What if we got married overseas?
Most overseas marriages are recognised under Australian law. You’ll need a translated marriage certificate (NAATI-certified) if it’s not in English. Same-sex marriages performed in countries that recognise them are usually valid in Australia too.
If we have a baby during processing, does our case get stronger?
Yes, significantly. A child of the relationship is among the strongest evidence possible. So notify Home Affairs through ImmiAccount immediately and upload the birth certificate.
Can we lodge as de facto if we still legally married to someone else?
Yes, technically. However, you cannot register your relationship in most states while still legally married elsewhere. So you’d need to satisfy the 12-month rule or rely on another exception. Also, you’d need to provide evidence the previous marriage has effectively ended.
Does the application fee differ between married and de facto?
No. Both pay the same base application charge of $9,365 (2025–26 financial year). The fee is determined by visa subclass, not by relationship status.
Should we get married just to strengthen the application?
No. Marriages entered into solely for migration purposes are grounds for refusal under Public Interest Criterion 4020. So marriage should be a relationship decision, not a visa strategy. If you’re already considering it, the visa benefit is a bonus. However, marrying purely to strengthen a visa case can backfire badly.
