Common Co-Tenancy and Subletting Questions in ACT

Renting in the Australian Capital Territory (ACT) can often involve shared housing arrangements, such as co-tenancy and subletting. These setups bring with them various questions and concerns. In this article, we'll delve into some of the most commonly asked questions about co-tenancies and subletting in the ACT, helping you navigate your rights and responsibilities as a renter.

Understanding Co-Tenancy

Co-tenancy occurs when two or more individuals sign the same lease agreement with a landlord. Each co-tenant shares responsibility for adhering to the lease terms, including paying rent and maintaining the property.

Key Rights and Obligations

  • Joint Liability: All co-tenants are jointly and severally liable. This means that if one tenant doesn't pay their share, the others must cover the shortfall.
  • Lease Changes: To change a co-tenant, you generally need the landlord's written consent and a jointly signed agreement by all tenants on the lease. Refer to the Residential Tenancies Act 1997 for specific provisions.

Navigating Subletting

Subletting occurs when a tenant rents out part or all of their rented home to another person. If you're considering subletting, there are crucial legal steps you need to understand.

Legal Considerations

  • Landlord's Consent: Secure written permission from your landlord before subletting. According to the ACT Residential Tenancies Act 1997, subletting without the landlord's consent is prohibited.
  • Subletting Agreement: Create a formal agreement outlining rent, terms of stay, and responsibilities. This document serves as protection for both parties.

FAQs on Co-Tenancy and Subletting

  1. What happens if a co-tenant wants to leave?

    A co-tenant can leave, but they remain liable for rent until they are removed from the lease. A Change of Tenancy Agreement needs to be signed by all current tenants and the landlord.

  2. Can a landlord refuse to allow subletting?

    A landlord can refuse permission if there are valid reasons, such as concerns over potential property damage or if the proposed subtenant doesn't meet criteria.

  3. How can disputes between co-tenants be resolved?

    Disputes may be settled through negotiation or mediation services. If unresolved, the ACT Civil and Administrative Tribunal (ACAT) can provide a binding resolution.
