Apart from anything else, family has zero obligation to pay their brother-in-laws medical bills after death (or before). Hospitals will pull all sorts of shady stuff to strongly imply that you should pay for a family members medical bill, however. From very strongly hinting that you're obligated to, through to impugning honor, "It would be doing the right thing by your dad", etc.
