Co-Owning Property in NSW? What to Sort Out Before You Buy Together

Intro


Co-ownership is on the rise—especially with rising property prices. Pooling resources with someone you trust can help you get into the market or invest together. But it’s critical to have legal clarity before you buy.


Why It Matters


Most co-ownership issues arise when things change. One person wants to sell. Someone can’t contribute anymore. A relationship changes. Without a co-ownership agreement, there’s no legal roadmap to follow—which often leads to dispute.


Choosing the Right Ownership Structure


Joint Tenants: both own the entire property. If one dies, the other inherits automatically.


Tenants in Common: each owns a set share, which can be sold or left in a Will. More flexibility, but more risk if things go wrong.


What a Co-Ownership Agreement Should Cover


  • Initial contributions (deposit, legal fees, stamp duty)

  • Ongoing costs (mortgage, rates, maintenance

  • Living arrangements and exclusive use

  • Rules for exit: how and when an owner can sell their share

  • Dispute resolution procedures


Future-Proofing Your Agreement


Think about what happens if one person:


  • Gets married

  • Loses their income

  • Wants to renovate

  • Wants to rent out their share


A well-drafted agreement can address these upfront.


Listing your app on the Apple App Store or Google Play involves more than ticking boxes.

Tax and Duty Considerations


Buying out a co-owner or restructuring ownership can trigger stamp duty or CGT. The agreement should outline what happens financially if one person exits.


Tip


You can include a clause requiring co-owners to offer their share to the other first before selling to a third party.


What to Do Next


Speak to your lawyer before signing a contract. Get clarity on the title structure, and ensure your agreement is written before settlement. I help co-owners set clear terms from day one—so expectations stay aligned.
