My parents took out a life insurance policy on me when i was young i have been adult can they cash it out now?

As I said in answer to your other question, this policy does NOT belong to you. It belongs to your parents. It is their property, they paid for it, and only they can make changes to it. You have no legal right to the policy at all.

You have no rights to that policy. You can not make changes to it. If it has a cash value, you can't borrow that. You can not cash it out. Your parents can make changes. Your parents can cash it out. You can't do anything related to that policy. Your parents are the owners of the policy. They do not have to show it to you or let you have any access to it. They are not "hiding" it from you. It's not your property. They don't have to show you that any more than they have to show you their tax documents. If you need life insurance you will need to get your own policy.

They can if they want to, but unless the policy has been in force over 40 years, it's probably not WORTH anything to cash out. Other relatives are trying to create trouble. No, beneficiaries CANNOT "cash out" a policy. Only the OWNER of the policy can cash it out, or borrow against it. And CHILD life insurance is SUCH a ripoff, when they do the math, they'll learn that they can't cash out NEARLY as much as they have paid into it, over the years. The owner of the policy, who has been PAYING for it, picks the beneficiaries, or can cancel the policy (cash it out), or can make changes, or borrow against it (under the wild assumption there's enough cash value to borrow against - not likely with child life insurance). It doesn't matter that you're an adult. It's not your policy. It hasn't been your money paying in. You can't make changes. Heck, you probably don't even understand that the DEATH benefit only pays out if you die - you can't borrow against that. Life insurance isn't a savings account, or an investment, or a cheap cash cow - it's a FUNERAL cost planning tool. If you want life insurance that YOU can control, go buy some.

They're probably "hiding" it from you...or just not giving it to you, because they don't trust you to not cash it in. They want to have some life insurance coverage on you in case you die. They own it so they get to decide what to do with it.

If they own the policy, you cannot "make changes to it." Only the policy owner can do that. Whether it has any cash value depends on the type of policy. If you need life insurance, you should be buying your own policy.

As other have said, the policy owner (not the insured party) controls the policy. You're age 40 and can't have an honest conversation about this with your parents? That's REALLY sad.
