Yes, you can. However, if your tenants are always late paying the rent, you should be serving them with the notice of non-payment of rent (Form N4) which gives them fourteen days to pay the arrears. If they do not pay within that time or make only a partial payment then you can apply to the Landlord and Tenant Board after the fourteen days are up. However, if they do pay up you will have to wait until the next time they are late and serve the N4 again. You may have to do this several times before attempting to evict them based on persistent late payment of rent, at which point you would serve a Form N8.
