My mom was the primary caregiver for my dad. She recently passed away. He will likely have to go into a nursing home because we are unable to be with him 24 hours/day and can not afford to pay a nurse. He will have to go on Medicaid. My brother recently found a letter from a collection agency in Dad's mail saying that a hospital bill for him that they were fighting before my mom died will be sent to the credit bureau if not paid by 3/8/18. He does not have the money to pay it. He has very little income and his only current asset is his house which will have to be sold. My question is should I pay it? What are the repercussions if we do not pay it?
