u need to lodge a report at IDAC first to ascertain the damages
u need to claim (if u intend to do a claim).
depending on ur insurance company, most will allow you to proceed
to repair ur damages once the initial survey reports are out nefore
they proceed to claim against any 3rd party. this will take time
and you do not need to pay any money to the insurance company (why
the hell do u think we pay an arm and leg for insurance?). however,
u will still need to pay the excess (depending on the named driver)
on your insurance if your claim against the 3rd party was
unsuccessful.
some companies will require you to claim your own insurance before
they proceed to investigate the liability. in whichever case, if
the claim against the 3rd party is successful, (if it is proven
that you were not at fault) you will not lose your NCB.
