Revoking (cancelling) a Power of Attorney (POA) can be easy. If you have a POA in place, you have the right to revoke that power if you no longer want that person(s) managing your assets and financial affairs.
If you lack capacity and your family members or others feel that your assets and financial affairs are being misused by your attorney, or your attorney is not acting in your best interests, the NSW Ageing and Disability Commission can help.
