Understanding Your Rights as a Co-Tenant in NSW

Living in a rental property with others in New South Wales comes with specific rights and responsibilities. Understanding these can help protect you from potential issues regarding co-tenancies and subletting. Whether you are a primary tenant or subletting, this guide will provide you with clear information to navigate your renting experience.

What is Co-Tenancy?

Co-tenancy occurs when two or more people sign the lease agreement as tenants. Each co-tenant shares the same rights and responsibilities under the tenancy agreement. In New South Wales, the Residential Tenancies Act 2010 outlines these obligations and rights.1

Responsibilities and Rights of Co-Tenants

As a co-tenant, you have equal responsibility for paying rent, maintaining the property, and adhering to the terms of the lease. Any breach of these terms by one tenant can affect all others. It's crucial to have a mutual understanding and agreement among all parties.

Understanding Subletting in NSW

Subletting refers to renting out part or all of your property to another person. In New South Wales, you must obtain written consent from your landlord before subletting. Without it, you risk breaching your lease agreement, which can lead to eviction.

How to Legally Sublet

  1. Obtain Written Permission: Request written consent from your landlord to sublet your premises. Without this, the subletting could be considered illegal.
  2. Draft a Subletting Agreement: Create a formal agreement with your subtenant outlining rent responsibilities, duration, and property maintenance duties.
  3. Ensure Compliance: Encourage your subtenant to comply with the original lease terms to prevent any complications.

Co-Tenancy and Subletting Disputes

Disputes can arise from shared living arrangements. It's advisable to resolve disagreements amicably. However, if necessary, you can approach the NSW Civil and Administrative Tribunal (NCAT) for formal dispute resolution.2
