Travel Insurance Policy Cancellation - When entire trip has been cancelled?

[Lethal]

I had bought a travel insurance policy (from 15th July'2011 to 31st July 2011) for my parents from Royal Sundram. Now the entire trip has been cancelled, so I am looking for cancellation of above travel insurance policy. I have few queries -
1- Do I still need to submit passport, as the travel date is far away from today?

Cancellation of the policy can be done only in cases, where a journey has not undertaken. In your case as the date of start of cover is later date, so no need to submit the passport.

2- Is there any charges for cancellation?

Yes, they charge admin fees around 5-10% of the policy premium.
