Not if she is listed as part owner of the vehicle.
You can "exclude" anyone from your policy. This is frequently done when a young person is of driving age and you don't want your policy to cover them because the rates would go up. So yes, you can exclude a current, separated, or whatever spouse or any other person from your policy.
While there might be a state law somewhere that allows it, I would be surprised. A separation does not remove the duty of each spouse to support the other. If the employee has the insurance befre the separation, he will have to keep it until a divorce, remarriage after divorce, she obtains her own insurance or a court orders otherwise.
That would not be a very nice thing to do, what you should do is write to your spouse and the insurance company, point out that you are now separated and indicating that you will no longer be paying for your spouses insurance after a fixed date in the future. This informs the insurance company of your intentions and allows your ex spouse to arrange their own health insurance.
If she is still being carried on his insurance as his spouse then she has insurance.
yes they can
If you are legally separated, you are free to see other people. South Carolina divorce does use adultery as one of the grounds options, but dating while you are separated is not adultery.
spouse did not know name was on policy or that the other name was removed without knowledge
That depends a great deal on the situation. There may be an insurance clause that would apply. Typically the estate must resolve the debts first.
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.
I would let your insurance company know. They can remove them from the policy. That might help lower your rates. Sorry for your lost.
If the separated spouse is still legally married to the debtor spouse and/or co-signed the original obligation while married, yes.
You are the "spouse" until you are no longer legally married.
