There is no such thing as a power of attorney for a dead person. It is also not legally possible to make oneself a power of attorney. Only a living person can give a power of attorney to anyone, and all powers of attorney legally cease to exist upon the death of the person who gives it. So anything the older son has done or is doing under a purported power of attorney is completely illegal and fraudulent. The power of attorney doesn't need to be revoked, since it is already totally invalid.
