A tenancy agreement is a legally binding agreement that can only be ended in certain ways.
An agreement may end:
when a fixed term has ended (correct notice has been given)
during a periodic agreement (correct notice has been given)
if the property manager/owner and tenant mutually agree in writing to end a fixed term
there is a serious unremedied breach (e.g. for unpaid rent, damage to the property, illegal use of property, property owner fails to maintain property)
a serious breach of the agreement occurs in the same way more than twice in one year (QCAT order)
the tenant has not complied with a QCAT order
the tenant has abandoned the property
the property is to be sold (and the tenant is on a periodic agreement)
a mortgagee is in possession of the property
sole tenant dies, or
QCAT order ends the agreement (e.g. for excessive hardship)
The person ending the agreement must use the correct form and comply with the appropriate notice period.
