What are the risks of being in a ‘De Facto’ Relationship?

Deemed de factos and de facto property entitlements: a little word of warning …

The modern approach to relationships finds many couples co-habiting long before considering marriage. However, you could be in a de facto relationship without even realising it – and, if so, your personal assets are at serious risk if you and your de facto part ways.

The Federal Government now has jurisdiction over de facto relationships under the Family Law Act 1975 (Cth) (“the FLA”).

Deemed de factos

Under the FLA, as soon you live with someone on a genuine domestic basis you are deemed to be de facto partners, provided you are not already related by family and not married to each other.

So, how do you determine whether you are living together on a genuine domestic basis? The considerations include:

  • The duration of the relationship;
  • The nature and extend of the couple’s common residence;
  • Whether a sexual relationship exists;
  • The degree of financial dependence;
  • The ownership, use and acquisition of their property;
  • The degree of mutual commitment to a shared life;
  • Care and support of children; and
  • The reputation of the relationship in the public.

If you live with someone on a genuine domestic basis and have a child, you are immediately considered a de facto couple for the purposes of the FLA, and have immediate property and maintenance entitlements.

There is no discrimination between heterosexual and homosexual relationships under these provisions of the FLA.

Some issues to be aware of – Centrelink and Income Tax Returns

Centrelink considers a couple to be in a de facto relationship from the time they start living together as a couple. It is important to keep this in mind when accepting or applying for Centrelink benefits as it may affect your entitlements.

The Australian Tax Office does not have a fixed timeframe for deeming a couple to be de facto – a couple can access tax benefits (such as offsets) as soon as they start living together as a couple.


The FLA allows a court to also make orders about superannuation interests if a claim is made by a de facto partner after the breakdown of the de facto relationship. This is an important power for the courts to have because many people hold a significant portion of their wealth in super.

However, the FLA provides a mechanism by which de facto partners (or people contemplating entering into a de facto relationship) can prospectively contract out of a court order about super in a Binding Financial Agreement or ‘BFA’ This is discussed further below.

Binding Financial Agreements

Binding Financial Agreements (or, as they are more commonly known, “pre-nups” or “BFAs”) are largely used before a couple become married, but they can also be entered into by de facto partners or people contemplating living together as a couple.

These agreements are a legally enforceable way to safeguard the assets that you have when entering a relationship. However, the agreement must comply with the various requirements in the FLA to withstand a challenge by an ex-partner, and we strongly recommend that both partners seek comprehensive legal advice before signing on the dotted line.

It is important to be aware that most Binding Financial Agreements will cease to have effect if you later marry your de facto partner, so it is worthwhile to re-assess the situation and seek new advice if you are planning to marry your de factor partner.

I am sincerely wanting to thank Marie and Catherine along with the extended Andreyev team for guiding me through the most terrifying, stressful and complex legal matter.

Along with the expertise and knowledge, the team at Andreyev helped guide me through the whole process with patience, kindness and understanding. The constant reassurance and professionalism conducted payed off in my legal matter.

I feel incredibly thankful that Marie and Catherine took my case and helped me start my new life.


As a Co-Founder and Executive Director of a fast-growing business securing the right legal advice is paramount to my professional needs, and personal security. Recognising I required the best of guidance and support I needed to find a legal practice and practitioner who could understand my specific needs and provide tailored recommendations to ensure my business kept growing and my assets remained secure.

From the onset I was delighted with the approach from Andreyev Lawyers. They took the time to understand my unique situation and provided considered recommendations. As I do not have a legal background, I particularly appreciated the clarity of communications enabling me to make clearly informed decisions. Subsequently, I decided to proceed with creating a Binding Financial Agreement (BFA) with my partner.

Andreyev Lawyers facilitated the BFA from beginning to end with great care and attention to detail, at each stage keeping me informed and supported. Their attentive and professional service not only resulted in the successful completion of the BFA but all parties ending very satisfied with the outcome due to the ease of process he had led.

I highly recommend Andreyev Lawyers for their professionalism and care and would not hesitate to engage them again in the future.

Don’t lose your business along with your marriage

Separation is never easy, but it can be even more difficult for business owners. This is because business owners have the added uncertainty of having their jobs (and often livelihoods) tied up in a business that is considered an asset of the relationship. For many business owners, the most daunting aspect of their separation is the possibility of losing their business.
