You cannot 'obtain' a power of attorney. A 'POA' can only be granted by the individual who is voluntarily granting that power themselves, to someone else. It cannot be coerced or it becomes illegal and invalid. You CAN obtain a court ordered "guardianship" over someone who you believe to be mentally/physically incapable of taking care of themselves or their obligations. You must petition the court and a hearing will be held to determine if the person is, or is not, legally competent. You must show the court good reason (probably including medical/psychiatric testimony) as to why it should order that person's individual rights taken away and given to you.
Medically exempt.
You must hire a family attorney who will proceed with all the steps necessary to have you made the woman's guardian. You cannot do this without an attorney and a judge declaring you are the legal guardian.
Generally speaking anyone can be asked to testify. Though someone can be ruled as medically or mentally unable or incompetent to testify.
If they are mentally competent, yes they can. They simply need to execute the statement to that effect.
As I understand it this claim (that he was declared mentally unfit for military service) is unsubstantiated.
If the owner in the home is still mentally capable, they can sign a deed. If they are not mentally capable then you must obtain a power of attorney (from a court) to deal with their affairs and the person with power of attorney can sign the deed (providing a copy of the power of attorney in support). If they are in a home and mentally capable and do not want to sign the deed then you can not transfer the car title.
If the husband has become mentally incompetent as a result of the stroke, he would not be considered mentally competent to grant a power of attorney to anyone. A power of attorney that is granted during the time of one's incompetency would generally not be considered valid. If a person is mentally incompetent, an interested person could generally petition a probate court (in the county in which the mentally incompetent person resides) to have a guardian of the person and the property appointed.
No. Only a competent person can execute a power of attorney, so (by definition) a mentally disabled person cannot execute a valid power of attorney. What would be necessary is the court appointment of a guardian for the brother. Of course, any proceeds from the sale of the brother's property would go first to repay the State of California for his care and the rest would be set aside to pay for his future care.
If they are mentally competent, yes. Their disability does not disqualify them.
If you want to be a climber, you should not be afraid of heights. You should be physically, mentally and medically fit. You all need the right attire for this purpose.
even though they are mentally impaired they should also dressed attractively so that they are nice to see.
Nothing unless person is declared to be mentally incompetent at the time the power of attorney was made
