Hi Jeremy Phuah, thanks for writing to us on AskGuru.
MCST refers to Management Corporation Strata Title (MCST) for the management of common property in strata-titled developments such as condominiums. The Building Maintenance and Strata Management Act (BSMA) provides that a non-profit corporation, called the Management Corporation (MC) must be formed by all the subsidiary proprietors (after legal completion) to own and administer the common property.

Hope this answers your question.
