Endorsement to a policy is issued if there is any change in terms and conditions of coverage, premium, deductible, change in name, address or such other policy particulars.

Here there is no change in the policy as you have only made a disclosure to the insurance company. Due to this additional disclosure, if there is some change to be made in the policy such as increase in premium or modifications in coverage, the insurance company will do an endorsement to that effect.

In the absence of any such action by the insurer, it has to be presumed that the insurer has taken your disclosure on board. Your claim cannot be denied on account of non disclosure of material fact on this account. You should however, keep the acknowledgment mail from the insurance company in this regard for your records.

Dear Surya

Do two things

1. Send a mail to service and ask them to send you service request number .

2. If you have a Bupa office in town then submit a letter and take acknowledgement ..

Ideally insurance company should endorse the declaration and you should also demand by calling their service center .
