How to co-own property without conflict, confusion, or costly mistakes

Buying property with family or friends is becoming increasingly common in today’s market. It’s an exciting achievement, but without the right legal framework co-owning property can lead to conflict, financial stress, and damaged relationships. You shouldn’t have to choose between getting into the property market and protecting your relationships with the people you care about.

With the right plan in place from the start, you can co-own property confidently, protect everyone’s interests, and keep your relationships strong. Call us on 1300 654 590 or email us to hear how we can help you.

Before you buy property with someone else, you need to plan for the “exit”. What happens if someone wants out? What if circumstances change or things go wrong? Property is a long-term, high-value investment, and while the chances of conflict may feel small at the start, when things go wrong, they go very wrong: financially, emotionally, and legally.

 

The problem isn’t what you know, it’s what you don’t…

Who actually owns what share? What happens if one person pays more upfront, or contributes labour instead of cash? What does “joint tenants” even mean, and is it right for your situation? These aren’t the questions you want to be figuring out after you’ve signed you’ve signed a contract.

That’s where we come in.

In our experience guiding clients through property co-ownership, we’ve learned that answering these key questions upfront saves you from painful problems later:

  1. Who owns how much?
  • Is an equal split between the owners, or should ownership reflect what each person actually put in?
  • Will costs (such as the deposit and mortgage repayments) be split evenly, or does one person carry more cost? Will someone pay more upfront, but less towards the mortgage repayments?
  • If someone’s contributing “sweat equity” through labour or renovations instead of cash, how is that fairly valued?

 

  1. How will title be held?
  • As individuals (either as joint tenants or tenants-in-common)?
  • Through a corporate or trust structure?

 

  1. How will the property be used?

Many co-owners don’t realise that as a starting point, each co-owner has the legal right to access and use the whole property, regardless of their ownership share.  No one can be excluded from spaces or claim a room as exclusively theirs.  You should think through:

  • If you’ll be living together: How will you handle a co-owner’s partner moving in? Will they pay rent or contribute to costs, and how will that be calculated? How will you manage guests (including what happens if someone overstays or causes damage) and what they’re expected to contribute?
  • If it’s a holiday home: Will you need a schedule to divide up each person’s time at the property? How are costs and utilities split? What happens when nobody’s using it?
  • If it’s an investment property: Who manages the rental process and decides on tenants? How are rental proceeds divided if ownership shares are unequal?
  • If the use changes down the track (say, one or both of you move out of the property and it becomes a rental): who makes that call, and what happens if you don’t agree?

 

  1. What happens if someone can’t pay?
  • How will you handle missed payments for the mortgage or other expenses related to the property?
  • What if there are significant costs incurred for maintenance or improvements and one owner can’t pay their share? Usually, another owner needs to pay the difference. Do they get compensated with a rate of interest, or are they entitled to acquire a further interest in the property?

 

  1. What are the roles and responsibilities of each owner?
  • Who will be responsible for arranging insurance on the property?
  • Who will hold and collate tax information?
  • Who will maintain the property?

 

  1. What about life events (divorce, bankruptcy, hardship)?
  • If a co-owner goes through divorce, bankruptcy, or financial hardship, how does that affect everyone else? If your co-owner’s share becomes part of family law proceedings, you can be drawn into those proceedings too simply by being a co-owner.

 

  1. How will decisions about the property be made?
  • By majority vote? Unanimous agreement?
  • What if there is a deadlock?

 

  1. What if someone wants out?
  • Does everyone have to sell as soon as one owner wants to sell?
  • Do the other owners have the first right to buy out their share?
  • How much notice does someone have to give that they want to sell?

 

  1. How are the proceeds distributed?
  • Are proceeds/income split 50/50? Or is it in your proportion of ownership?
  • Do historical contributions need to be taken into account?

 

  1. What are the impacts of owning the property on each co-owner?
  • What will the impact of the property be on a pension a co-owner receives (or would like to receive down the track)? What if they need to sell their share of the property to pay for aged care?

 

Left unaddressed, these issues can lead to unnecessary arguments, significant costs, and, in extreme cases, permanently damaged relationships with the people you care about most.

 

The good news is that most of these problems are preventable.

By having open conversations and putting a Co-Ownership Agreement in place, you can buy property with your loved ones without conflict, confusion, or costly mistakes.

Don’t wait for things to go wrong, call us on 1300 654 590 or email us to get started on a Co-Ownership Agreement.

 

Co-Ownership Agreement vs BFA

If you are planning on buying a property with friends or family, a Co-Ownership Agreement is the way to go.

If you are buying property with your spouse or de-facto partner, a Co-Ownership Agreement will not be legally binding. If the relationship breaks down, the property will be dealt with under the Family Law Act 1975 (Cth) as part of a property settlement.

If you and your partner aren’t quite there yet, you might decide to proceed with a Co-Ownership Agreement. However, you need to be aware that once you are married or considered a de-facto couple, it will no longer be legally binding.

What happens if we don’t get a Co-Ownership Agreement?

Maybe everything goes smoothly.

But what if it doesn’t? Without a Co-Ownership Agreement, you may have no choice but to apply to the Court to force a sale of your share of the property.

Here’s the catch, a 50% share of a property doesn’t always equal 50% of the property’s value, and in some cases, the entire property may have to be sold. If it comes to this, you’ll all face significant costs, emotional exhaustion, and strained relationships. From our experience, long legal battles rarely leave relationships intact. Further, you will lose control of the sale process as it will be in accordance with whatever the Court decides.

This should be a last resort but it’s completely avoidable! Don’t let it get this far. Call us on 1300 654 590 or email us to learn how you can protect your property and your relationships today.
