Is a victim of unauthorized credit card purchases liable to pay the bill

Most credit card companies excuse charges made by a thief with a stolen credit card. Since the "thief" in this case is your son-in-law, prepare for the company to argue that the card was not "stolen" and you knew your son-in-law better than they did, thus between the two of you, the company is the more innocent victim. However, if the store did not check I.D. and the receipt was forged, there may be liablilty to the store and certainly to your son-in-law for fraud and/or theft. Your question does not present enough facts to give you a more detailed response; call a lawyer in your area or try to locate one at the Avvo site. Good luck.
