There are certain things you need to do in order to maintain your insurance coverage.
Pay your premiums on time. If you do not pay your premiums on time, your policy may be cancelled for non-payment. Your coverage will stop and you will no longer be protected. If your policy is cancelled due to non-payment, you may find it difficult to get coverage in the future, or you may have to pay higher premiums.
For some types of insurance, you must tell your insurer as soon as possible about any change in your circumstances that may affect the insurer's ability to cover your losses. For example, your automobile insurer will need to know if you have convictions for driving offences.
To renew your policy, you may need to tell the insurer about any changes to that information within a certain time period before your current policy ends. Your policy will list the specific procedures you will need to follow to renew your policy.
