How can I trace my policy no and amount and claim maturity amount?

I am separated from my husband. He has kept all my LIC policy papers and not willing to give them back. I don't know any details about the policy. I just know that they are about to mature. How can I trace my policy no and amount and claim maturity amount?

Without policy no or the branch name it is almost impossible to get the maturity amount.
If you know the agent, via whom your insurance policy had taken, he may help you out.
