By way of background, a Certificate of Currency (CoC) is issued by your Owners Corporation’s Insurer, usually at the request of lenders at the time of a Lot’s sale or refinancing, and it confirms that there is a current policy in place and the amounts of monetary coverage for individual risks as of the date that it’s issued.
I’ve found that a copy of the receipted Policy Schedule will usually suffice in such circumstances, but if a CoC is requested of an Owners Corporation’s Strata Manager by a lender or by an individual Owner then the Insurer charges a fee for preparing it, and that’s what your Strata Manager is passing on, possibly together with their own admin. fee for making the (on-line) application.
So YES…. that’s common practice, and if there is an admin. fee from your Strata Manager then that would be declared in one of the Schedules to their Agency Agreement.
