Which insureance is best for someone with a terminal illness: life or burial?

I am sorry to learn of your brother's condition. Life insurance is based on health, so it is not an option. If your brother is going to be receiving Medicaid, the pre-payment of his funeral and burial will protect those assets from being subject to Medicaid spend down. You can prepay his final expenses by going to a funeral home and making the arrangements or through the purchase of a final expense trust, which is a form of life insurance. Pre-paying these expenses relieves his loved ones from having to make difficult decisions during a time of mourning.
