Navigating Co-Tenancy Risks in ACT

Renting a home with others in the Australian Capital Territory (ACT) can offer many benefits such as shared expenses and companionship. However, it's crucial to be aware of the risks associated with co-tenancies and subletting to avoid potential conflicts and legal issues. Here, we explore these risks and how you can protect yourself as a renter.

Understanding Co-Tenancies in the ACT

In a co-tenancy, all tenants sign the lease agreement and share equal responsibility for the property, rent, and other obligations under the Residential Tenancies Act 1997. This means that if one co-tenant fails to pay their share of the rent, the other tenants are liable for covering the shortfall.

Common Risks of Co-Tenancies

  • Financial Liability: If one tenant fails to pay rent, the others must cover their share to avoid eviction.
  • Disputes: Conflicts about cleaning responsibilities, noise levels, or sharing of expenses can arise.
  • Lease Violations: Unauthorized subletting or damaging property can lead to disputes with the landlord or other tenants.

To mitigate these risks, consider drafting a co-tenant agreement detailing each person's responsibilities and procedures for conflict resolution.

Subletting in the ACT: What You Need to Know

Subletting occurs when a tenant rents part or all of their rented premises to another person. In the ACT, you must get written consent from your landlord to sublet, as per the Residential Tenancies Act 1997. Failing to do so can result in eviction for breach of lease terms.

Potential Issues with Subletting

  • Lack of Control: As the original tenant, you're responsible for the actions of your subtenant, which can include unpaid rent or property damage.
  • Consent Requirement: Without landlord consent, you risk legal consequences, including eviction.
Tip: Always document all agreements in writing and ensure proper communication with your landlord and other tenants.

Handling Disputes in ACT Tenancies

If conflicts arise, whether with a landlord or among tenants, the ACT Civil and Administrative Tribunal (ACAT) is the body responsible for handling residential tenancy disputes. You can apply to ACAT for dispute resolution if needed.
