In NSW, oral (verbal) tenancy agreements are legally valid and enforceable under the Residential Tenancies Act 2010. If there is no written agreement, the standard terms set out in the Act still apply automatically to both parties.

However, without a written record, disputes over specific terms - such as the rent amount, bond, or any special conditions - can be difficult to resolve. Landlords who fail to provide a written agreement when required may also face penalties under the Act. A written agreement is strongly recommended to protect both parties and provide a clear reference point throughout the tenancy.
