As the property is some 70 years old it seems the Articles have never been changed and remain as is from 1960. The levies also remain unchanged since 1960.
OMG…If your levies have never been changed since the 1960’s then you must be laughing with the minimal payments you are all making as shareholders to keep the company/unit block going.
Perhaps you are not being as frank as possible as to divulging past events in your unit block. You have posted before on this forum, with a previous question pertaining to a shareholder intending taking over the laundry area as part of their shareholding. You have been given some sage advice in relation to this.
Who managed the unit block prior to 5 years ago? Where are the records? If you can get other shareholders on side with your issues of concern, then pay a company title lawyer to impart some legal advice as to the validity of property boundaries.
If you aren’t prepared to do this, then selling up to be rid of your neighbors who are causing you so much angst may be your only recourse.
