Are you on the 6th Edition ADLS Form or something else? If you are on the 6th Edition clause 27.5 will allow you a right of an abatement of a fair proportion of the rent. “Fair” proportion depends on your circumstance, but market at the moment suggest at least 50%. If this is the cause of the dispute, the lease contains a dispute resolution process that can be triggered.
If you are not on the 6th Edition (e.g. some mall leases), this provision may not be in your lease – and the discussion may well be more of a commercial negotiation regarding a rent deferral rather than an abatement. Happy to discuss on 021 705 914. Phil
