I hope this information helps …. From the Office of Fair Trading web site: All strata schemes must review their by-laws by 30 November 2017. NB: It appears that your Scheme has already reviewed your By-laws at your last AGM thereby complying with this requirement.
Owners can adopt a model by-law as their own or make their own by-law.
Owners corporations can choose to adopt these model by-laws or make changes to better suit their circumstances to manage issues in strata like overcrowding, pets, parking, and smoke drift. Schemes are not required to adopt or adapt any of the model by-laws, they are available to assist schemes in reviewing and making by-laws to suit their scheme. Model by-laws cannot be the by-laws for your scheme unless they are first formally adopted by the owners corporation and registered with the Office of the Registrar-General.
Model By-Laws are here:
