Welcome to Yahoo Finance’s legal column where lawyers Alison and Jillian Barrett from Maurice Blackburn tackle problems everyday Aussies face — whether it be consumer, property, money matters impacting relationships or work. This week, a father’s concerned about a financial leg up he gave his son to get on the property ladder.

Question

My son built a house on land we gave him funds to buy. When it was completed, he and his girlfriend moved in. They have lived in the house together now for several years. If their relationship broke down would she be entitled to any settlement from the property? She contributes with the usual living expenses while he pays his mortgage. Could our gift contribution be included in a settlement payout if there was one?

Answer

Navigating property settlements following the breakdown of a relationship can be a complex and emotionally charged process. Hopefully, your son never needs to tackle this.

RELATED

In Australia, de facto couples have similar rights and obligations as married couples when it comes to property settlement. According to the Family Law Act 1975, a de facto relationship is defined as a relationship between two people who are not married to each other but live together on a genuine domestic basis.

Given that your son and his girlfriend have lived together for over four years, their relationship would likely be considered de facto under Australian law.

If their relationship breaks down, either party can apply for a property settlement.

The court will consider various factors to determine the division of property, including the duration of the relationship, the financial and non-financial contributions made by each party, the future needs of each party, and the care and support of any children from the relationship.

A precise formula isn’t applied (or a 50/50 split), it depends on the circumstances of the case.

In your son’s case, his girlfriend’s contributions to the usual living expenses and the fact that they have lived together for over four years would be taken into account.

If her financial contributions were intended to be rent and there is documentation to support this, then it could influence the property settlement.
