> How can I be legally responsible for my parents?
Well your parents are legally responsible for you for a period of time. There are many countries (I am most familiar with Germany in this regard) where the children are considered responsible for the parents. I was not aware this was the case in the USA.
In some countries it's quite difficult / impossible to disown or disinherit various relatives.
In Germany, the obligation to pay alimony depends on the child's income. Only when the childs income (before taxes) excceeds 100,000 Euros per anno she/he has to pay something. There exists no obligation to pay alimony for grandparents.
The law provides for exceptions in serious cases. However, the German Federal Court of Justice has interpreted this quite strictly. A son who had no contact with his father for 40 years and was disinherited except for the compulsory portion still had to pay alimony. The court reasoned that the son had received substantial assistance from the father during his first 18 years and that the father had only made use of his right to testamentary freedom.[1]
Just a side note: If someone has received gifts from a person who later becomes destitute, he or she must return the gift under certain conditions (the gift was made no more than 10 years ago, the recipient was not destitute on his or her part, it was not a gift of decency such as a small birthday or Christmas present, etc.).
