The RTB8 form is for a tenant to use if they do not get a response to the initial notice of delay form.
If you have sent an initial notice of delay form (RTB6) to your landlord they must then either move the sale along within 1 month or send you a ‘counter notice’. The counter notice will say that they’ve already replied or explain why they can’t speed things up.
If your landlord doesn’t reply within a month of getting the RTB6, fill in the ‘operative notice of delay’ form (RTB8).
This means that any rent you pay while you’re waiting to hear from your landlord could be taken off the sale price.
