Not every couple applying for an Australian partner visa is married, and Home Affairs treats de facto relationships as fully equivalent to marriage for visa purposes — provided you can prove the relationship is genuine and meets the legal definition. The catch is that “de facto” carries specific legal requirements that surprise a lot of applicants, particularly around the 12-month cohabitation rule.
Here’s what actually qualifies, what doesn’t, and how the exemptions work.
What Counts as a De Facto Relationship?
Under Australian migration law, a de facto relationship exists when two people, regardless of gender, are not married to each other but live together on a genuine domestic basis. Home Affairs looks at the same four categories of evidence used for married couples — financial, household, social, and commitment — to decide whether the relationship is genuine.
Where de facto applications differ from married applications is the additional requirement to prove the relationship has existed for a minimum period before you can apply.
The 12-Month Rule
In most cases, you need to have been living together in a de facto relationship for at least 12 months immediately before lodging your visa application. This isn’t 12 months of dating, or 12 months of a long-distance relationship — it specifically means living together under one roof as a couple.
Short periods of separation (for work, family obligations, or travel) generally don’t break this continuity, provided the relationship clearly continued throughout. But the bar is living together, not just being a couple, so this is one of the most misunderstood requirements in the entire partner visa process.
Exemptions to the 12-Month Rule
You don’t always need to meet the full 12 months. There are two main pathways around it:
- Registered relationship — if your relationship is registered under an Australian state or territory relationship register, the 12-month living-together requirement doesn’t apply in the same way, because the registration itself serves as formal evidence of the relationship.
- Compelling and compassionate circumstances — Home Affairs can waive the requirement where there are reasons that justify it, such as situations involving family violence, or other circumstances that genuinely prevented the couple from living together for the full period.
Relationship Registers
Several Australian states and territories run relationship registers that let de facto couples formally register their relationship, similar in effect to a marriage certificate. If you’re not yet at 12 months of cohabitation but want to apply sooner, registering your relationship (where eligible) can be the most straightforward way to do that — assuming you otherwise meet the eligibility criteria for registration in that jurisdiction.
Evidence That Specifically Matters for De Facto Claims
Because there’s no marriage certificate to lean on, de facto applicants generally need a more robust evidence file across all four categories. Case officers tend to scrutinise these applications a little more closely, simply because there’s no single legal document doing the heavy lifting that a marriage certificate provides.
- A clear timeline of when cohabitation began, supported by lease agreements or shared address documents
- Joint financial commitments that started early in the relationship, not just recently
- Consistent evidence of social recognition as a couple from the same approximate starting point
- Statutory declarations (Form 888) from people who can confirm specifically when you started living together
Common Mistakes in De Facto Applications
- Assuming dating for 12+ months satisfies the requirement, when it specifically requires cohabitation
- Applying just under the 12-month mark without a clear exemption basis
- Inconsistent dates between the two partners’ statements about when they moved in together
- Not addressing periods of separation directly, leaving the case officer to assume the worst
- Relying heavily on social evidence (photos, social media) while under-supporting financial and household evidence
Same-Sex De Facto Couples
Australian migration law treats same-sex de facto relationships identically to opposite-sex relationships for partner visa purposes — the same 12-month rule, the same evidence categories, and the same exemptions apply. If you’re in a same-sex relationship and want more detail on documentation specific to your situation, that’s covered in more depth elsewhere on evidence strategy for these cases.
If You’re Close to the 12-Month Mark
Couples sometimes ask whether it’s better to wait until they’ve cleared 12 months or to apply early using an exemption. The honest answer depends heavily on the strength of your specific case, and it’s worth getting that assessed properly rather than guessing. The team handling partner visa Australia exemption cases at One Planet Migration Law regularly works through exemption arguments for couples who are close but not quite at the standard threshold, and can tell you fairly quickly whether an exemption pathway is realistic for your situation or whether waiting is the safer call.
What If You’ve Lived Together On and Off?
Couples who’ve moved in and out of shared accommodation for practical reasons — study, work contracts, family circumstances — sometimes worry this breaks their cohabitation timeline. Home Affairs generally looks at the substance of the relationship rather than treating any short interruption as fatal, but the burden is on you to explain these periods clearly rather than leaving the case officer to interpret gaps unfavourably. A short written explanation alongside your evidence addressing any obvious gaps in shared addresses tends to resolve this concern proactively.
De Facto Couples With Children
If you have children together, this is meaningful evidence of a genuine de facto relationship, and birth certificates naming both partners can help establish both the relationship and its timeline. That said, having a child together doesn’t automatically satisfy the cohabitation requirement on its own — you’ll still want supporting evidence across the financial, household, and social categories to build a complete picture.
International De Facto Relationships
If part or all of your relationship took place overseas before either of you moved to Australia, that time can still count toward your de facto history, provided you can document it. This often means gathering evidence from a different country’s systems — overseas lease agreements, foreign bank statements, utility bills in another language requiring translation — which takes more lead time to assemble than evidence generated entirely within Australia.
How De Facto Evidence Strategy Differs by Life Stage
Younger couples just starting out together often have less financial entanglement (separate leases, less joint property) simply because of where they are in life, while couples in their thirties, forties, or later may have deeper financial ties but a shorter relationship history if it’s a second relationship after a previous marriage or partnership ended. Both situations are entirely valid, but each benefits from a slightly different emphasis in how the evidence is gathered and presented.
Frequently Asked Questions
Does a de facto relationship need to be registered to qualify for a visa?
No, registration isn’t mandatory — it’s one route to an exemption from the 12-month rule, but you can still qualify as de facto through standard evidence of 12 months’ cohabitation without ever registering the relationship.
Can same-address roommates be mistaken for a de facto relationship, and does that cause problems?
Living at the same address alone doesn’t establish a de facto relationship — Home Affairs looks at the full picture across financial, social, and commitment evidence, not just a shared address, so this isn’t typically a source of confusion in genuine applications.
What if we lived together for 12 months but broke up briefly during that time?
A genuine, short-term breakup during the relevant period can complicate a straightforward 12-month claim, and it’s worth addressing this honestly and directly in your application rather than hoping it goes unnoticed, since case officers may identify gaps in evidence regardless.
Final Thoughts
De facto partner visa applications are entirely viable and successful every day in the Australian system — but they do require a slightly more deliberate approach to evidence than married applications, simply because there’s no certificate doing part of the proving for you.
