Notice to Vacate - Failure to pay rent
If a Notice to Vacate is issued because you have rent in arrears and it is the first or second notice within twelve (12) months, you can pay the full arrears before the effect date and the notice ceases to have effect.
The landlord/agent must accept the arrears if you pay them during the notice period. If it is the third Notice to Vacate for being behind in rent in a 12 month period, the landlord/agent can require you to vacate even if you catch up.
To summarise, if you catch up on the rent within 14 days then you cannot be evicted unless it is your third notice in 12 months.
