Residential Tenancies Act 1986, s 56
Either you or your landlord can apply to the Tenancy Tribunal for a termination order ending the tenancy if the other side has breached the tenancy agreement or the Residential Tenancies Act and hasn’t fixed the problem. The other side has to have been given a notice saying what the problem is and telling them to fix it within a set time, which has to be at least two weeks. The Tribunal can end the tenancy if it’s satisfied that it would be unfair (“inequitable”) not to do this. The landlord can use this process if, for example, you’re behind in the rent or you’ve damaged the property.
