How do you find a lawyer for caregivers rights?

Is child living with elderly parent, legally responsible if medication is not taken (by senile parent) correctly and parent ends up in hospital?

You should find an elder law attorney who knows what is legal for adult caregiving in your state. You don't need to be licensed to care for a family member (in most states) but if you are caring for someone else, you should check with your state regulations. An elder law attorney can help answer both questions.
