Can I get out of my body corporate?
In theory, yes, but the practicalities mean the answer is usually no.
If you lot is physically in a tower or part of a gated community the answer is definitely no. The local authority will simply not allow that.
If you are in a duplex or something very small it might be possible but the first place to check is the town planning restrictions. The local authority may have approved the scheme only because it was strata titled. Leaving a small body corporate like this means dissolving the body corporate – which will only be able to be done with the support of all other owners.
