There are various ways a tenancy agreement can end. Fixed term tenancies have a set ending date (see 'Fixed term or periodic tenancies?'). A landlord or tenant may seek to end an agreement in certain circumstances. An 'interested party' such as a tenant's neighbour may also seek to end a tenancy if the tenant's conduct is unacceptable.
At the end of an agreement, there are certain steps that should be taken to finalise the relationship between landlord and tenant.
In some instances, specific notices or forms should be served on the other party as part of the process of finalising a tenancy. For copies of the relevant forms, visit the SA Gov - Forms and Factsheets for Private Rental Tenancies website.
