Is Your Landlord Violating Co-Tenancy Laws?

Understanding the complexities of co-tenancy and subletting agreements in Victoria is essential for any renter involved in shared housing arrangements. This guide provides insights into whether your landlord might be violating co-tenancy or subletting laws, helping you ensure your rights are safeguarded.

Co-Tenancy and Subletting: What You Need to Know

In Victoria, a co-tenancy arrangement means all tenants are on the lease, sharing equal responsibility for rent and damages. Subletting, on the other hand, involves a tenant renting out their space to another party. Both arrangements require landlord consent under the Residential Tenancies Act 1997.1

Recognizing Violations

Landlords may violate these laws if they:

  • Refuse to grant consent for subletting without valid grounds
  • Impose excessive fees for adding a co-tenant
  • Fail to recognize rights of all tenants on the lease

It's crucial for renters to know their rights and responsibilities to prevent and address potential violations.

Action Steps if You Suspect a Violation

  1. Communicate with Your Landlord: Start by discussing your concerns directly with your landlord. Open communication can often resolve misunderstandings.
  2. Use Official Forms: If negotiation fails, submit a Tenant Notice to Landlord of Breach of Duty (Form 9). This form formally notifies your landlord of the purported breach.
  3. Seek Mediation: If issues persist, VCAT (Victorian Civil and Administrative Tribunal) offers a platform for dispute resolution. More information can be found on the VCAT website.
Always maintain records of your communication and any submitted documents. They might be crucial if the dispute escalates.

Need Help? Resources for Renters

If you're struggling with a landlord violating co-tenancy or subletting laws, reach out to these resources for support and advice:


  1. How do I know if I am in a co-tenancy or subletting arrangement? Determine by checking the lease agreement; in a co-tenancy, all tenants are named, whereas subletting involves a separate agreement with the sitting tenant.
  2. Can my landlord increase rent for new co-tenants? Rent increases require proper notice and, in some cases, landlord consent, especially when a new tenant is added.
  3. What should I do if my landlord refuses to acknowledge a breach? If communication fails, formalize the complaint with a Tenant Notice to Landlord of Breach of Duty (Form 9) and consider seeking VCAT intervention for resolution.

  1. What should I do if my landlord refuses to acknowledge a breach? Begin by sending a formal written notice of the breach to your landlord. If this does not resolve the issue, consider seeking resolution through VCAT.
