1. How to change my agent?
There is no need and no provision to change your LIC agent, as there is no contract between you and an LIC agent. As far as a policyholder is concerned, the contract is with insurance company. The agent is just a facilitator.
2. If I delay premium payment for 2-3yrs, what will be the consequences ?
Depending on the policy type, periodicity of premium payment and grace period, the policy may lapse. In some cases, the policy may be reactivated by paying all arrears premium with extra charges and interest; and medical check up also may be needed. You have to contact concerned LIC office or nearby LIC office for specific details.
3. If I withdraw policy, is there any refund or I will loose all money, so far i paid 3.5lakhs in premium?
Policy cannot be unilaterally withdrawn, but surrendered. Please read the policy terms and conditions. There will be a surrender value after a lock in period. Depending on the period run, type of policy and policy terms, you may get a fraction of the premia paid and some bonus. The policy if already assigned to someone, then the amount can be claimed by the assignee only by forfeiture. Please contact the LIC branch along with your policy document for specific details.
