Handling Co-Tenancy and Subletting Disputes in WA

Sharing a rental property in Western Australia can be economical and convenient. However, disputes in co-tenancies and subletting arrangements can arise, causing stress for all parties involved. Understanding your rights and the correct procedures can help in handling these disputes effectively.

Understanding Co-Tenancy and Subletting

A co-tenancy occurs when multiple people sign a single lease agreement, sharing responsibility for rent and property care. On the other hand, subletting involves a tenant renting out a portion or all of the leased property to another person not on the original lease.

Common Disputes and Their Causes

  • Unpaid rent or bills by one of the tenants
  • Breaches of lease terms, such as damaging the property
  • Disagreements over household responsibilities

Legal Framework in Western Australia

Disputes related to co-tenancies and subletting in Western Australia are primarily governed by the Residential Tenancies Act 1987 (WA)[1]. Understanding this act can provide clarity on responsibilities and rights.

Resolving Disputes

It is advisable to first attempt resolution through open communication between all involved parties. If this fails, tenants can seek formal resolution methods.

Key takeaway: Always communicate openly with co-tenants or sub-tenants to prevent misunderstandings from escalating into legal disputes.
