What if someone put you on their credit card without authorization from you are you responsible for that bill once that person dies?

If someone added you as an authorized user to their credit card without your consent, you typically wouldn't be responsible for the debt after their death. Authorized users are not legally liable for the debt incurred on the card; that responsibility lies with the primary cardholder. However, if you were a co-signer or had any legal obligation, the situation might differ. It's advisable to consult a legal expert for specific guidance based on the circumstances.
