Yes!
The person named beneficiary is the sole recipient, the ex-spouse would not have a supportable claim to any portion of the death benefit.
The Excluded person would have no coverage under the policy. That person would have to have had their own separate policy or there is "no" coverage.
Under normal circumstances, no. A life insurance company will pay the proceeds to the named beneficiary.
Usually the insurance company will want him and his spouse to have their own insurance policy as they should have. If there is some reason for him to be on your policy like the car is still in your name they will probably let you do it. Make sure he is listed as a driver, his spouse is listed as a driver, and anyone else that should be listed is on the policy. If the car is in his name and he does not live with you do not put it on your insurance as there may not be any coverage is a claim happens. Make sure the insurance company know the whole truth about the situation.
No.
Excluded drivers are "NOT" covered on that policy. That's the point of excluding them from coverage. This is insurance fraud and they will not pay.
You do have a right to have a policy on your spouse as you have insurable interest. However you can not take out a policy with out the consent of the person to be insured. There is underwriting that has to be done including possible bloodwork and maybe a physical exam. Your spouse will need to sign to have this completed as well as giving permission for medical records to underwrite the life insurance policy. If you find someone to claim they can does any other way you are probably not dealing with an moral/ ethical company and I would have questions when it comes to claim time if they would pay.
An insurance policy should still remain valid for the remaining term following a claim providing that the claim is such that it does not require the insurer to cancel the policy. You should check with your insurer.
Read your policy
If the life insurance policy had listed as the beneficiary the spouse only then it is not considered part of the estate and is not subject to claims. If the beneficiary is the estate then it is subject to claims. The only problem with the spouse being the only beneficiary is if she was a party to the claims personally then perhaps she and the proceeds from the life insurance could be subject to these claims.
In fact, term insurance policies can be called no risk no fault insurance, as no claim is payable during the tenure of the policy and only in the event of death of the policy holder, claim is payable to the nominated person of the policy.
Although there is no legal requirement in some states, an insurance company will answer questions from the executor of an estate, owner of the policy, or whoever had power of attorney over the policy at the time of the insured's death. The beneficiary has no right to any information on a policy until a claim is to be paid to them.
