Risks Renters Face with Co-Tenancies & Subletting in NSW

Living in co-tenancies or subletting arrangements is common among renters in New South Wales. While sharing a residence can offer financial and social benefits, it can also expose tenants to various risks. Understanding these potential issues is crucial for protecting your rights and ensuring a harmonious living environment.

What Are Co-Tenancies and Subletting?

In New South Wales, a co-tenancy occurs when two or more people are named tenants on a single tenancy agreement. All co-tenants have equal rights and responsibilities under the Residential Tenancies Act 2010. Subletting, on the other hand, involves an existing tenant leasing part or all of the rented premises to another person, referred to as a sub-tenant.

Risks and Challenges

  • Liability for Rent and Damage: In a co-tenancy, each tenant is jointly and severally liable for the entire rent and any damages to the property. This means if one tenant fails to pay rent, the others must cover the shortfall to avoid breaching the agreement.
  • Eviction and Notices: If issues arise, such as unpaid rent, all co-tenants may face eviction notices, risking housing stability for all parties.
  • Disputes Among Tenants: Disagreements may lead to a hostile living environment. It's vital to establish clear agreements among co-tenants regarding responsibilities and expectations.

Legal Requirements and Rights

Subletting usually requires the landlord’s written consent. Without it, you risk breaching your tenancy agreement, which might lead to eviction. Familiarize yourself with your rights under the Residential Tenancies Act 2010 to avoid pitfalls associated with unauthorized subletting.

Tip: Always negotiate rental terms clearly and document any agreements made among co-tenants.

Where to Get Help

  1. Contact NSW Fair Trading for issues regarding rent increases, repairs, and unfair evictions.
  2. Consult the NSW Civil and Administrative Tribunal (NCAT) for tenancy disputes.

It's important to keep communication open with your landlord and co-tenants and regularly review your tenancy agreement to ensure all parties comply with their obligations.

Need Help? Resources for Renters


  1. How can I legally sublet in NSW? Ensure you have written consent from your landlord before subletting. Discuss expectations with your sub-tenant and use a formal subletting agreement.
  2. What if my co-tenant stops paying their share? Communicate with your co-tenant first. If unresolved, you might need to cover their share temporarily while planning further action, such as a dispute hearing at NCAT if necessary.
  3. Can I be evicted if only one co-tenant fails to comply? Yes, if one co-tenant violates the agreement, all tenants could be at risk of eviction unless resolved swiftly.
  4. What forms are needed for tenancy issues? Use the 'Notice to Terminate' form for ending agreements due to breaches, found on NSW Fair Trading.
