Legal Question in Elder Law in Kentucky

Re: Power of attorney.

(1) What are the duties and powers of power of attorney (POA),with respect to an elderly family member(care responsibilities of that elderly person)...

Usually, to manage financial matters. If the POA is more specific, it might include personal matters, including medical consent, etc. However, this would normally be done by utilizing a healthcare surrogate rather than POA. If in doubt, you should consult the attorney who drafted the POA.

and (2)the other children in the family.

The only such obligation would be to not misuse funds which might later be part of the inheritance, or to otherwise take advantage of the person who granted the POA.
