I was joint on my brothers bank accounts. He died in July 2013. I closed the money market account but left the checking account open to pay bills. I am getting medical bills for services he received. I paid 3 but I know there is still one for over $5000. He had no will, no estate, no heirs. Only these accounts (in Florida). I live in Michigan. Am I liable for his medical bills? Do I have to use the joint account money and pay his bills? These are above and beyond insurance/medicare.
