After this period, the policy is considered incontestable, meaning the insurance company cannot dispute its validity based on misrepresentation or other factors.

What is the validity of a demand draft issued by state bank of India?

Any demand draft/ bankers cheque is normally valid for a period of six months from the date of issue. However if the demand draft is presented after the validity period, the bank still pays it, so long as the bank still holds that amount in its custody, by simply updating the validity, and may be cashed any given time. It may charge a small sum if the amount is above a particular slab. So therefore for all practical purposes the DD or bankers cheque remains still valid, any given time so long as the bank holds the amount and is the custodian of the amount, on behalf of the payee.
