Usually a power of attorney is not responsible for the principal's debt. Only if the debts are caused by the power of attorney's grossly irresponsible acts can the power of attorney be held liable, according to Nolo.

Generally, if the power of attorney follows instructions given by the principal, there is little legal risk involved, according to Nolo. Only when the power of attorney strays from the principal's instructions and wishes does he have a risk of liability.

Upon death of the principal, the power of attorney is relieved of all duties to the principal's instructions and of all legal liabilities. This includes the principal's debt, according to Nolo.

Power of attorney is not responsible for the principal's debts, unless she previously shared joint responsibility for debts. In this case, the power of attorney will more than likely have to pay the debts, according to Nolo.
