What can be done if an individual who has Power of Attorney is misusing the credit cards of the POA grantor?

Why do they "know" they won't be held responsible? They believe the person who issued the POA will never find out, or ...? Being given a POA is not a license to steal/self-deal. One has a fiduciary duty to the person who issued the POA. * A POA becomes null and void upon the death of the grantor. When the deceased estate is probated any misuse of funds or mishandling of property will be discovered upon the auditing of the estate. A person abusing POA authority can be held directly responsible for such actions and said acts could result in both criminal and civil penalties.
