ACT Co-Tenancies & Subletting Guide

Navigating co-tenancies and subletting in the Australian Capital Territory (ACT) can be challenging, yet understanding your rights can make it much more manageable. Whether you're considering adding a roommate or subletting part of your rental, being informed about the legal aspects under the Residential Tenancies Act 1997 can protect your interests.

Understanding Co-Tenancies in the ACT

Co-tenancy occurs when two or more tenants sign a lease, sharing equal responsibility for the property and its rent. The main benefits include shared rental costs and shared utility expenses. However, co-tenants also share the responsibility for the property's condition and any breaches of the lease.

Responsibilities of Co-Tenants

  • Sharing rent payments equally or as per agreement
  • Maintaining the property in good condition
  • Jointly managing any legal obligations related to the tenancy.

Adding or Removing Co-Tenants

If you wish to add or remove a co-tenant, you need the landlord's written consent. The process typically involves completing and lodging relevant forms with your landlord. For detailed steps, you can view the ACT Revenue Office website.

Navigating Subletting

Subletting is an arrangement where the primary tenant rents out part or all of the premises to another person, known as the sub-tenant. In the ACT, subletting requires the landlord's written consent.

Steps for Subletting

  • Seek the landlord's permission through the appropriate form.
  • Draft a sublease agreement that aligns with the main lease.
  • Ensure all parties understand their rights and responsibilities.

Legal Considerations

The Residential Tenancies Act 1997 regulates subletting and co-tenancies in the ACT. It is crucial to ensure compliance with these regulations to avoid potential disputes or legal issues. Learn more about your rights under this legislation.
