If you're wanting to find out if someone has a life insurance policy in Texas, there are a few ways you can go about it.
You can start by contacting the person's life insurance company directly. If they are insured through a specific company, that company should have records of the policy. You could also try searching for the person's name in the Texas Department of Insurance's Life and Health Policy Locator.
If you're unable to find any information through those methods, you could also try contacting a local life insurance agent. They may be able to help you locate a policy or put you in touch with someone who can.
