Reviewing your earlier question, I understand that you have now found the Will that generally cuts you out.
If you are not receiving any assets from your husband then you are not legally liable for debt that was in the sole name of your husband. This would specifically apply to credit card debt.
There is a possibility that you are liable for the medical bills if there are not enough assets that he left to the sisters to cover the cost of the medical bills.
I cannot provide you with legal advise. I have provided you with information about the law related to your question. My answer, and any information that you find online, should not take the place of having a consultation with a lawyer in your area to advise you regarding your specific issues.
