Is your husband legally responsible for unpaid medical bills if he is the primary insured?

Yes, your husband is legally responsible for unpaid medical bills if he is the primary insured. As the primary insured, he is ultimately responsible for ensuring that all medical bills are paid, regardless of whether he is the one who received the medical care or not. This means that if you and your husband incur any medical expenses that are not covered by insurance, he will be responsible for paying them. It's important for both of you to understand this responsibility and to make sure that you have a plan in place to pay for any potential medical bills.
