Help for Co-Tenancies & Subletting in ACT

Living in a co-tenancy or subletting situation in the Australian Capital Territory (ACT) can sometimes lead to unique challenges. Whether you're facing issues with rent increases, disputing tenancy terms, or managing repairs, knowing where to turn for help is crucial. This guide provides an overview of support options available to renters in the ACT.

Understanding Co-Tenancies and Subletting in the ACT

In the ACT, a co-tenancy involves more than one individual signing a lease and sharing rights and responsibilities under the Residential Tenancies Act 1997. On the other hand, subletting occurs when an existing tenant rents out part or all of the premises to another person.

Both situations require clear communication and understanding of responsibilities to avoid disputes. You should familiarize yourself with your rights and obligations to ensure a smooth renting experience.

Where to Get Help for Co-Tenancies

  • Understand Your Lease Agreement: Review your lease agreement to understand your rights as a co-tenant or subletter. If in doubt, seek clarification through legal advice.
  • Engage with Tenancy Services: Canberra's Tenants' Union ACT offers free information and advice for tenants, including assistance on co-tenancy issues.

You can also apply to the ACT Civil and Administrative Tribunal (ACAT) for advice or dispute resolution regarding tenancy matters. For example, if you are unfairly evicted or need help with a rental bond, ACAT can help mediate the situation.

Forms and Applications

  • Notice to Vacate: This form is used to formally notify a tenant they must vacate the property by a specified date. It must comply with ACT tenancy regulations, which require proper notice periods based on the reason for eviction.
  • Change of Shared Residential Tenancy: This form allows co-tenants to request changes within shared tenancies. It is beneficial for updating or removing a tenant from a lease agreement. Access the form on the ACT Revenue Office website.

Key Legislation

The conduct of landlords and tenants is primarily governed by the Residential Tenancies Act 1997 in the ACT. Additionally, the Fair Trading Act 1987 (Cth) protects consumer rights at a federal level, including those in rental agreements.

  1. What should I do if a co-tenant leaves the lease? You need to update the lease agreement with your landlord and potentially find a new co-tenant to cover the shared responsibilities and costs.
  2. How can I dispute a subletting arrangement that isn’t working out? Raise the issue with the primary tenant and seek advice from legal advisors or make an application to ACAT for a resolution.
  3. Is written consent required for subletting? Yes, you must obtain written consent from your landlord to legally sublet any part of your rental property.

  2. Engage in negotiation: Initially, try to negotiate with your co-tenants to reach a mutually agreeable solution on rent disputes.
  3. Seek advice from Tenants' Union ACT: Refer to the Tenants' Union ACT for expert advice on how to resolve rental issues.
  4. Apply to ACAT for mediation: If disputes cannot be resolved informally, consider applying to ACAT for formal mediation or resolution.

Need Help? Resources for Renters

If you're renting in the ACT and need assistance, several local resources are available:


  1. How can I add or remove a co-tenant legally? You need the landlord's approval and may need to use a form like the "Change of Shared Residential Tenancy" to officially update the lease.
  2. What happens if a subtenant damages the property? In most cases, the primary tenant is responsible for any damages caused by a subtenant unless otherwise stated in the subletting agreement.

In summary, the key to a successful co-tenancy or subletting arrangement in the ACT is awareness of your rights and responsibilities, effective communication, and knowing where to seek help when needed. Utilizing the available resources can make navigating these complex arrangements much smoother.
