An eviction notice, usually called a Notice of Termination, may be invalid if it gives too little notice, is not properly written or signed, has the wrong termination date, or is not served correctly. It may also fail if the landlord does not state a legally required reason, follow the correct procedure for rent arrears or another breach, or send a copy to the RTB where required. The exact requirements depend on the reason for termination and the tenancy’s circumstances. The RTB ultimately decides whether a notice is valid, so consider getting advice from Threshold or a solicitor.
