My father passed away last year in a nursing home. He left no estate as all of his assets went to pay for his care. The nursing home has now filed a lawsuit against my sister and I for 13,000 that they say is the unpaid balance. We have no way to verify this is even the amount owed as the home never sent an itemized bill. I never signed anything stating I was willing to take responsibility for this debt. We are in PA, Can the home just sue us for a random amount of money that they claim my deceased father owed them and can we be held responsible for paying it? We are in no position to take on anyone else's debt.
