These are the raw versions of my Flat Chat columns for the Sydney Morning Herald’s ‘Domain’ section. Some of the issues are specific to New South Wales, some are universal. There will almost certainly be differences in strata law between NSW and other states and countries. If you have a serious problem, contact the agencies (in Australia) listed in our contacts sections. Or contact a properly qualified and experienced strata lawyer. These columns should not be regarded as a substitute for professional legal advice.
