yes
ia an additional credit card holder liable for the whole debt of the credit card account
Depends on what "Type" of Credit Holder you are. Here is how that will go: If you are what is known as an authorized user on the account. (i.e. - The Primary account holder has given you permission to make charges on the account), the answer is No. The primary account holder is responsible for any charges he/she has allowed you to make on the account. If you are a Secondary account holder (i.e. -your name was put on the account APPLICATION at the time the card was applied for), then your answer is YES. If the Primary account holder defaults on the account, then the credit card company will turn to try and collect from the Secondary account holder. BEWARE of becoming a secondary holder on anything that has to do with credit. If you know that the Primary holder may default, you could get stuck with a huge amount of debt on your hands, and if you can't pay, your nice credit score of 783 could very quickly go down the drain to 535 or lower.
Account holder deceased
If you are a joint account holder you can still use the card. The creditor should be notified of the death of the other account holder. They may simply remove the person from the account or require you to open a new account in your name. However, if you are the joint holder you are responsible for the entire amount owed on the account.
Name of account holder refers to the name of the person who owns the account. This can be for bank accounts, credit accounts, loans or utility services.
No you must close the account.
Illinois is not a community property state, therefore a spouse who is not a joint account holder is not responsible for the credit card debt of the other spouse.
No, credit card accounts are not transferrable. It might be possible for the person to become a joint account holder, but that would depend upon the card issuer's lending policy.
A joint account holder cannot be removed from the account, the account will have to be closed.
Interest does not accrue on credit card debt after the card holder is deceased. It can occur however, if the spouse is on the account.
Yes, as long as your listed as a "Co-signer" on the account. Credit is not build if you are just an "Authorized User" if this was a credit card account. Lastly, this all assumes that whatever this joint-account is that it reports to credit.
If the cardholder has an estate, the credit card company can pursue that. In practice they don't really do that. If the account is a joint account, the other account holder becomes wholly responsible for the debt. Otherwise the bank eats the money.
