They would have to prove to the court that the POA was awarded AFTER the effects of the Alzeheimer's had become a factor in the ward's mental processes. If it was awarded BEFORE the ward manifested the illness this might prove a difficult burden to overcome.
In most cases they would not be able to serve in that capacity. The court is not likely to appoint someone with Alzheimer's to serve as executor.
No only the grantor can revoke a power of attorney. That may be the court. And death will terminate the power of attorney.
The power of attorney terminates on the death of the principle. At that point the family makes decisions.
no, having joint custody gives you more control than having power of attorney.
The power of attorney has no rights after the death of the grantor.
The power of attorney will have control of the property as long as the individual remains living. The life estate and the power of attorney expire on the death of the grantor.
If a life insurance beneficiary has alyztimers and is in a nursing home, can the power of attorney or nearest living relative receive it?
It would depend on who granted the uncle the power of attorney. If the grandmother granted the PoA, she can revoke it at any time. If the PoA was granted by a court, no she cannot.
If the Attorney In Fact dies, then the Power of Attorney is null. In most states this means that if the individual is incapacitated the next of kin can have that person adjudicated incompetant in Probate/Family court and can take over the affairs. NB: a Power of Attorney is a document. An Attorney In Fact is the person to whom a power of attorney is granted.
You need to speak with an attorney as soon as possible. If your mother is legally incapacitated she cannot execute a POA document nor can she change her will. You need to petition the court to be appointed her guardian so that you can take care of her, her assets and protect her from predators. You should consult with an attorney who specializes in elder affairs or probate. Do not delay.
Unless you were specifically granted a "General Power Of Attorney" your responsibility and powers extend only as far as to what was granted in the POA you possess. You should consult an attorney to have them read it for the specifics.
No one because a power of attorney represents a living person. The power of attorney ends with the death of the grantor. They can apply to the court to be made executor, but there is no precedence.
